Fig. 1 is a scene architecture diagram of an application scene to which a packet routing method according to an embodiment of the present invention is applied. In particular, referring to fig. 1, the application scenario relates to a cross-room communication system, which includes a central room 10 and a plurality of front-end rooms 20. The number of room devices (e.g., servers) included in the center room 10 and the number of room devices included in each front-end room 20 are not limited. The method steps in the embodiment of the present invention may be executed by any or designated equipment in the corresponding equipment room, and specifically may be executed by a process in the equipment room.

In the prior art, machine rooms in a communication system crossing machine rooms are generally distributed in different countries or regions, communication is performed based on the Internet, the statuses of the machine rooms are generally equal, when one machine room a (which may be called a starting machine room) wants to send a data packet to another machine room B (which may be called a destination machine room or a destination machine room), the data packet is directly sent according to the address of the machine room B, and the Internet Protocol (IP) interconnection between the machine room a and the machine room B is unreliable due to the fact that the network quality between the machine room a and the machine room B cannot be guaranteed due to various factors, and the problems can be improved to a certain extent by adopting network lines such as IPLC and the like, but the cost is high, and the implementation of enterprises is not facilitated.

In the embodiment of the present invention, a central machine room 10 is additionally provided in a cross-machine-room communication system, other machine rooms related to actual services are called front-end machine rooms 20 or ordinary machine rooms (such as the machine room a and the machine room B), the front-end machine room 20 detects network quality from the machine room to other machine rooms, and sends network quality detection information containing network quality information to the central machine room 10, the central machine room 10 can plan a data routing path with network quality superior to that of the original path sent from the starting machine room to the destination machine room directly according to the network quality detection information reported by each front-end machine room 20, and sends the data routing path to the front-end machine room 20, and the front-end machine room 20 sends data packets according to the received data routing path, so that network quality of the path in a data packet sending process can be improved, and probability of successful reception of the data packets can be improved.

Fig. 2 is a schematic flow chart of a packet routing method according to an embodiment of the present invention, where the method may be executed by a packet routing apparatus, where the apparatus may be implemented by software and/or hardware, and may be generally integrated in a machine room device, such as a server, of a central machine room in a communication system across machine rooms. As shown in fig. 2, the method includes:

step 201, network quality detection information sent by a front-end machine room is obtained, wherein the network quality detection information includes network quality information from the machine room to other machine rooms, which is detected by the front-end machine room.

For example, the central machine room may directly receive the network quality detection information reported by the front-end machine room, may also receive the network quality detection information reported by the front-end machine room and forwarded by other machine rooms or devices, and may be actively obtained by the central machine room or actively sent by the front-end machine room. The acquired network quality detection information may be from all front-end machines in the communication system, or may be from part of the front-end machines in the communication system. Generally, network quality information between two machine rooms may be different according to different machine rooms from which detection is initiated, that is, between the machine room a and the machine room B, the machine room a detects that the network quality from the machine room to the machine room B is a, and the machine room B detects that the network quality from the machine room to the machine room a is B, where a and B may be the same or different, if a and B are the same, only part of network quality detection information sent by front-end machines may be obtained for reducing data volume transmission, and of course, even if a and B are the same, in order to ensure information accuracy, network quality detection information sent by all front-end machines in a system may also be obtained, and specifically, the network quality detection information may be set according to actual requirements. The network quality detection information includes network quality information from the machine room to other machine rooms detected by the front-end machine room, and the other machine rooms may include the front-end machine room, and may also include a central machine room or a machine room with other functions, such as a central agent machine room in the following, which is not limited specifically.

For example, the network quality may be measured by using an indicator such as a packet loss rate or Round-Trip time (RTT). Optionally, the network quality information may include at least one of a packet loss rate and RTT. Of course, other more indexes or parameters may be selected for evaluating the network quality, and the dimensionality of the network quality information is enriched, such as data Packet transmission Delay, data Packet Delay Variation, data Packet Error Rate, and the like, taking a data Packet as an IP Packet, which may include IP Packet Transmission Delay (IPTD), IP Packet Delay Variation (IPDV), IP Packet Error Rate (IPER), and the like, so that more accurate network quality information may be obtained, and may be specifically set according to actual requirements.

Illustratively, when the front-end computer room performs network quality detection, a first preset frequency may be used for detection, and reporting is performed at a second preset frequency, and when reporting, network quality conditions from a last reporting time to a current reporting time may be summarized to obtain network quality detection information to be reported. The first preset frequency may be higher than or equal to the second preset frequency, and the values of the first preset frequency and the second preset frequency may be set according to actual conditions, for example, the first preset frequency is 1 time/second, and the second preset frequency is 0.1 time/second.

Step 202, determining a data routing path from a starting point machine room to a destination machine room according to network quality detection information corresponding to a plurality of front end machine rooms, wherein the starting point machine room and the destination machine room comprise the front end machine rooms, and the network quality corresponding to the data routing path is superior to that from the starting point machine room to the destination machine room.

For example, the number of the front-end machines in this step may be less than or equal to the total number of the front-end machines in the communication system. The data routing path may also be referred to as a data transit path. For every two front-end machines in the communication system, one of the front-end machines (assumed machine room a) may be determined as a starting-end machine room, the other machine room (assumed machine room B) may be determined as an ending-end machine room, and a path with better network quality from a to B is calculated, for example, the network quality from a to B may be determined according to the network quality detection information from the machine room a to the machine room B reported by the machine room a (assuming that the packet loss rate is evaluated and the packet loss rate from a to B is 10%), then the network quality from a to other machine rooms may be determined according to the network quality detection information from a to other machine rooms reported by a, and the network quality from other machine rooms to B may be determined according to the network quality detection information from the machine room to B reported by other machine rooms, for example, the packet loss rate from a to C is 0, and the packet loss rate from C to B is 0, so that the network quality corresponding to the path from a to C and then to B is better than the network quality from a to B, the path may be used as a data routing path corresponding to a, and at this time C may be referred to as a transit room in the path. Of course, if the packet loss rate from C to B is 5%, the packet loss rate from C to D is 0, and the packet loss rate from D to B is 0, the path from A, C, D to B in sequence may also be used as a data routing path corresponding to a, that is, the number of transit rooms may be two or more. Subsequently, B may be used as a starting point computer room, a may be used as a terminal point computer room, and the data routing path corresponding to B may be determined by referring to the above-mentioned process. It is understood that each front end machine room in the communication system may become a start-point machine room, a terminal machine room, or a relay machine room.

Optionally, the determining a data routing path from the starting point machine room to the destination point machine room according to the network quality detection information corresponding to the multiple front-end machine rooms includes: and determining a data routing path from the starting machine room to the terminal machine room according to a preset maximum hop threshold and network quality detection information corresponding to the front-end machine rooms, wherein the hop count of the determined data routing path is less than or equal to the preset maximum hop threshold. The advantage of setting up like this lies in, restricts the hop count of data routing route, is equivalent to control the quantity of transfer machine room, can guarantee the transmission efficiency of data packet, improves the success rate of data packet transmission when also guaranteeing data packet transmission efficiency promptly. The preset maximum hop count threshold may be set according to actual requirements, for example, 6.

Step 203, issuing the data routing path to a corresponding starting machine room, for instructing the starting machine room to send a corresponding data packet to a corresponding destination machine room according to the data routing path.

For example, after determining the data routing paths corresponding to the starting machine rooms, the central machine room issues the data routing paths to the corresponding starting machine rooms, and may instruct the starting machine rooms to send data packets to be sent to the corresponding destination machine rooms through the relay machine rooms according to the corresponding data routing paths.

By adopting the technical scheme, when the front-end machine rooms transmit the data packets, the routing paths of the data packets are planned by the central machine room according to the network quality information among the front-end machine rooms, so that the network quality of the paths in the data packet transmitting process can be improved, and the probability of successfully receiving the data packets is improved.

In some embodiments, the sending the corresponding data packet to the corresponding destination computer room according to the first data routing path includes: acquiring a first original data packet corresponding to a terminal machine room in the first data routing path; packaging the first original data packet and the related information of the first data routing path into a load of a first data packet based on a preset communication protocol, wherein the related information of the first data routing path comprises first address information of a terminal machine room in the first data routing path; determining second address information of the transit machine room according to the first data routing path; and sending the first data packet to the relay machine room according to the second address information, so as to instruct the relay machine room to forward the first original data packet to a corresponding destination machine room according to the first address information. The method has the advantages that the first original data packet and the related information of the first data routing path are packaged into the load of the other data packet and sent to the transfer machine room, and the transfer machine room can successfully acquire the first original data packet and the real destination machine room from the load by analyzing the received data packet and perform subsequent forwarding operation, so that the real destination machine room can successfully receive the first original data packet. The preset communication Protocol may be, for example, a User Datagram Protocol (UDP), and the first address information and the second address information may be, for example, IP addresses.

Optionally, the first address information of the destination machine room may include address information of a service interface process in the destination machine room, that is, address information of machine room equipment to which the service interface process in the destination machine room belongs; the second address information of the relay machine room can include address information of the relay forwarding process in the relay machine room, that is, address information of machine room equipment to which the relay forwarding process in the relay machine room belongs. The actual destination of the first original data packet may be a destination server in the destination room, the first address information may further include address information of a final receiving device (e.g., the destination server) of the first original data packet, and the service interface process in the destination room may forward the first original data packet to the service destination process in the destination server after receiving the first original data packet.

In some embodiments, the first data routing path includes at least two relay rooms, and the related information of the first data routing path further includes second address information of other relay rooms except for the first relay room; the sending the first data packet to the relay machine room according to the second address information, configured to instruct the relay machine room to forward the first original data packet to a corresponding destination machine room according to the first address information, including: and sending the first data packet to a first relay machine room according to second address information corresponding to the first relay machine room, and being used for indicating the first relay machine room to send a second data packet to a next relay machine room according to the second address information of the next relay machine room, wherein a load of the second data packet comprises a first original data packet corresponding to the first data routing path, the first address information and second address information of the remaining relay machine rooms. The configuration has the advantages that when a plurality of relay rooms exist, the number of second address information contained in the data packet to be transmitted can be sequentially reduced according to the positions of the relay rooms in the whole path, and the data packet transmission efficiency is improved. The remaining relay rooms may include a relay room located after the next relay room in the first data path, and the remaining relay rooms have not received the data packet including the first original data packet.

For example, the first data routing paths are A, C, D, E to B, C, D and E are relay rooms, then a packet a sent to C contains an original packet that a originally sends to B, first address information of B and second address information of D and E, C extracts second address information of the next relay room D (i.e. next hop) from the original packet a after receiving the packet a, encapsulates the original packet, the first address information of B and the second address information of E into a packet B, sends the packet B to D according to the second address information of D, D extracts the second address information of the next relay room E from the received packet B, encapsulates the original packet and the first address information of B into a packet C, sends the packet C to E according to the second address information of E, E receives the packet C, and B can extract the original data packet sent by A from the data packet d, thereby completing the data packet sending from A to B.

It can be understood that the first front-end machine room may also become a relay machine room, and when the identity of the first front-end machine room is the relay machine room in the second data routing path, the third data packet sent by the second front-end machine room may be received, where the third data packet includes a second original data packet corresponding to the second data routing path, first address information of the destination machine room, and second address information of the remaining relay machine rooms, and a fourth data packet is sent to a next relay machine room according to the second address information of the next relay machine room, where a load of the fourth data packet includes the second original data packet corresponding to the second data routing path, the first address information, and the second address information of the remaining relay machine rooms. It is to be understood that, when the first front-end machine room is the last transit machine room, the payload of the fourth packet does not need to include the second address information of the remaining transit machine rooms.

In some embodiments, the method may further comprise: receiving a first uplink signaling routing path corresponding to the first front-end computer room and issued by the central computer room, wherein the first uplink signaling routing path is determined by the central computer room according to network quality detection information corresponding to a plurality of front-end computer rooms, the first front-end computer room is a starting point in the first uplink signaling routing path, and the central computer room is a terminal point in the first uplink signaling routing path; and reporting the network quality detection information to the central machine room according to the first uplink signaling routing. The method has the advantage that the success rate of the central machine room for receiving the network quality detection information reported by the front-end machine room can be improved.

In some embodiments, the encapsulating the first original packet and the information related to the first data routing path into a payload of a first packet based on a preset communication protocol includes: when detecting that the size of a first data packet is larger than a first preset value after the first original data packet and the related information of the first data routing path are encapsulated to the load of the first data packet based on a preset communication protocol, splitting the original load of the first original data packet into at least two original sub-loads; for each original sub-load, encapsulating the packet header of the first original data packet and the current original sub-load into corresponding fragment packets, wherein fragment packets except the last fragment packet are provided with fragment identifiers, and fragment packets except the first fragment packet are provided with fragment offsets; and for each fragment packet, packaging the current fragment packet and the related information of the first data routing path into the load of a corresponding first data packet based on a preset communication protocol, wherein the number of the first data packet is consistent with that of the fragment packets. The sending the first data packet to the relay machine room according to the second address information, configured to instruct the relay machine room to forward the first original data packet to a corresponding destination machine room according to the first address information, including: and sending the first data sub-packet to the transfer machine room according to the second address information, and instructing the transfer machine room to forward the sub-packet to a corresponding destination machine room according to the first address information, so that a service interface process in the destination machine room can transmit the sub-packet to a destination server in the destination machine room, and instructing the destination server to obtain the first original data packet according to the sub-packet recombination. The advantage that sets up like this lies in, can promote communication system to the processing performance of great data package, and directly with big package (big data package) split into a plurality of small packages (little data package), and avoid the merging of terminal computer lab business interface to the packet, can directly pass through and give real final purpose server, avoid the extra performance consumption of terminal computer lab, promote the concurrency performance of handling big package, and guarantee that same packet head keeps the packet head the same under the circumstances of burst transmission, avoid out of order scheduling problem, the transmission reliability has been strengthened.

For example, the first preset value may be freely set, and may be, for example, a Maximum Transmission Unit (MTU), the MTU is used by the data link layer to limit the size of the data packet that can be transmitted, and the value of the widely used ethernet is 1500, that is, one ethernet packet can carry 1500 bytes of data at most. Generally, the number of the original sub-loads can be two, which can meet the requirements of the current technical level, and the number can be more along with the development of related technologies such as network protocols and the like. When the original load is split, the splitting can be performed on average or in a preset size. For example, the preset size is 800 bytes, and if the original payload is 1500 bytes, the original payload can be split into 800 bytes and 700 bytes; if the original payload is 1500 bytes, the original payload can be split into 600 bytes, and 300 bytes. The fragment id may be used to indicate that the current fragment packet is followed by other fragment packets, such as a fragment flag (MF). The slice offset may be used to represent the sum of the sizes of all slice packets prior to the current slice packet. For example, a fragmentation offset of 100 may indicate that the sum of the sizes of the preceding fragmented packets is 800 bytes. After a plurality of fragment packets are generated according to the original data packet, each fragment packet can be used as the original data packet to perform encapsulation of the data packet sent to the relay machine room, and the data packet obtained by encapsulation can be called a data sub-packet. Because the packet headers of the fragment packets are consistent with the packet headers of the original data packets, the destination server can reassemble the original data packets according to the packet headers of the original data packets, the fragment flag bits and the fragment offset, and finally complete the transmission of the original data packets.

In some embodiments, the switch in the first front end machine employs a policy routing configuration. The receiving a first data routing path corresponding to the first front-end machine room and issued by the central machine room includes: receiving, by the switch, a first data routing path corresponding to the first front-end computer room and issued by the central computer room, and forwarding the first data routing path to a service interface process in the first front-end computer room when determining, based on the policy routing configuration, that a preset field in a control signaling corresponding to the first data routing path is a preset value; receiving the first data routing path through the traffic interface process. After said receiving said first data routing path through said traffic interface process, further comprising: announcing first address information of a terminal machine room in the first data routing path to the switch through the service interface process based on a preset routing protocol, so as to inform the switch to forward a first original data packet sent to the terminal machine room in the first data routing path to the service interface process; the sending the corresponding data packet to the corresponding destination computer room according to the first data routing path includes: and sending the corresponding data packet to a corresponding terminal machine room through the service interface process according to the first data routing path. The method has the advantages that the switch adopts the strategy routing configuration, the service interface process declares the address information of the terminal machine room to the switch based on the preset routing protocol, the switch can deliver the original data packet sent to the terminal machine room to the service interface process for processing, the service non-perception access mode can be realized, when the service is accessed into the communication system provided by the embodiment of the invention, the matching modification is not needed, the universality of the communication system is improved, and the cost of a service party is saved.

Optionally, the switch may be a core switch. Generally, a router or a core switch may forward an IP packet according to a destination address of the IP packet, but Policy-Based Routing (PBR) may implement forwarding according to other attributes of the IP packet, such as a source IP address, a Type of Service (TOS), or a packet length. The preset field may be, for example, a TOS field, and the preset value may be a pre-negotiated value for indicating that data or signaling is to be forwarded to the traffic interface process. The preset routing Protocol may be a Protocol for updating routing information to the switch, and may be, for example, Border Gateway Protocol (BGP) or link state routing Protocol (Open short Path First, OSPF).

Optionally, when the communication system further includes a central agent room, the method further includes: and sending network quality detection information to the central agent room, wherein the network quality detection information is used for indicating the central agent room to forward the received network quality detection information to the central agent room.

Optionally, when the communication system further includes a central agent room, the method further includes: and receiving a first data routing path which is sent by the central agent machine room and corresponds to the first front-end machine room. Optionally, if the first data routing path issued by the central machine room is successfully received, the corresponding data packet is sent to the corresponding destination machine room according to the first data routing path issued by the central machine room, and if the first data routing path issued by the central machine room is not successfully received, the corresponding data packet is sent to the corresponding destination machine room according to the first data routing path sent by the central agent machine room.

Fig. 5 is a flowchart of a packet routing method according to an embodiment of the present invention, where the method is applicable to a front-end machine room (denoted as a first front-end machine room) in a cross-machine room communication system, where the communication system further includes a central machine room, a central agent machine room, and multiple other front-end machine rooms.

Illustratively, the method may comprise:

step 501, reporting the network quality detection information to a central machine room and sending the network quality detection information to a central agent machine room, and instructing the central machine room to determine a data routing path from a starting machine room to a destination machine room according to the received network quality detection information reported by the first front-end machine room and the received network quality detection information reported by other front-end machine rooms.

The network quality detection information comprises network quality information from the machine room to other machine rooms detected by the front-end machine room, the starting machine room comprises a first front-end machine room, and the network quality corresponding to the data routing path is superior to the network quality from the starting machine room to the terminal machine room. After receiving the network quality detection information sent by the first front-end machine room, the central agent machine room forwards the network quality detection information to the central machine room.

Step 502, a core switch receives a first data routing path and a first uplink signaling routing path corresponding to a first front-end machine room, which are issued by a central machine room.

Optionally, the first data routing path and the first uplink signaling routing path may be included in the same control signaling to implement simultaneous delivery, or may be included in different control signaling to implement separate delivery. In the first front-end machine room, a control signaling sent by the central machine room is received through the core switch.

Step 503, when it is determined that the preset field in the control signaling corresponding to the first data routing path is a preset value based on the policy routing configuration through the core switch, forwarding the first data routing path to the service interface process in the first front-end computer room.

The policy routing configuration may specifically be a PBR configuration.

Step 504, receiving the first data routing path through the service interface process, announcing first address information of the destination machine room in the first data routing path to the core switch based on a preset routing protocol, and notifying the core switch to forward the first original data packet sent to the destination machine room in the first data routing path to the service interface process.

Illustratively, the pre-set routing protocol may be BGP. When a server in a first front-end machine room generates a data packet to be sent to a certain machine room (or can be understood as a service interface process sent to the machine room), the data packet is sent to the core switch in a unified manner, and the service interface process has announced to the core switch that the sending of the first original data packet is processed by the service interface process, so that the core switch can forward the original data packet to the service interface process.

And 505, acquiring a first original data packet corresponding to a destination machine room in a first data routing path sent by the core switch through the service interface process.

Step 506, encapsulating the first original data packet and the related information of the first data routing path into a load of the first data packet based on the preset communication protocol through the service interface process.

The related information of the first data routing path includes first address information of a destination machine room in the first data routing path, and specifically may be address information of a service interface process in the destination machine room.

Optionally, when it is detected that the size of the first original data packet is greater than a first preset value, the original load of the first original data packet may be split into at least two original sub-loads. For convenience of description, an example of splitting an IP big packet into two IP small packets is described below, fig. 6 is a schematic diagram of an unpacking process provided by an embodiment of the present invention, and fig. 7 is a schematic diagram of an unpacking principle provided by an embodiment of the present invention, and referring to fig. 6, the unpacking process may include:

step 601, when it is detected that the size of the first original data packet is larger than a first preset value, splitting the original load of the first original data packet into at least two original sub-loads.

When a service interface process of a first front-end machine room (also called a source machine room) receives a source IP packet, a new IP packet may be constructed, the source IP packet is placed in a UDP load of the new IP packet, and if it is determined that the total size of the new IP packet exceeds MTU, the load of the original IP (IP of the source IP packet) may be split into 2 parts, where the first part is the first 800 bytes and the second part is the part after the first 800 bytes are deducted. Currently, the MTU of the ethernet is 1500, and as shown in fig. 7, assuming that the original load is 1480 bytes, if the information related to the first data routing path is added, it may exceed 1500, and therefore, the MTU is split into the first 800 bytes and the second 780 bytes.

Step 602, for each original sub-payload, encapsulating the header of the first original data packet and the current original sub-payload into a corresponding fragment packet.

Wherein, the first slice packet is provided with a slice identifier (MF bit), and the second slice packet is provided with a slice offset (100). Illustratively, the header of the source IP packet is a real IP header, the header of the first fragment packet is an IP1 header, the header of the second fragment packet is an IP2 header, and the IP1 header, the IP2 header and the real IP header are the same, i.e., the IP quintuple is maintained. The IP five-tuple refers to a set of five quantities, namely an IP source address and a destination address, a source port and a destination port of TCP/UDP, and an IP transport protocol, and the five-tuple is generally used to uniquely identify a session in network transmission. In this way, the entry module (which may be understood as a module in the service interface process responsible for adding the relevant information of the first data routing path) is equivalent to receiving 2 IP fragment packets, and the two fragment packets are processed separately.

Step 603, for each packet, encapsulating the current packet and the related information of the first data routing path into the corresponding load of the first data packet based on the preset communication protocol, wherein the number of the first data packet is consistent with the number of the packet.

As shown in fig. 7, a new IP header is added to two fragment IP packets, a non-fragment identifier is set, and the fragment packets and the information (e.g., UDP shown in the figure) related to the first data routing path are used as the load of the first data packetization, and the first data packetization is obtained by encapsulation. The new IP header may be set according to the first address information of the destination machine room (or, when there are a plurality of relay machine rooms, may be set according to the second address information of the next relay machine room).

And 507, determining second address information of the relay machine room according to the first data routing path through the service interface process, and sending the first data packet to the relay machine room according to the second address information, so as to instruct the relay machine room to forward the first original data packet to a corresponding destination machine room according to the first address information.

For example, if the packetization operation is performed as described above, the first data may be packetized and sent to the relay room according to the second address information.

As shown in fig. 7, after receiving the two data packets, the service interface process in the terminal equipment room decapsulates the two data packets, takes out the fragment packets, and sends the fragment packets to the final destination server, and after receiving the two fragment packets, the final destination server may reassemble the two fragment packets into one IP packet according to the IP1 header and the IP2 header, so as to obtain the source IP packet.

And step 508, when it is detected that the network quality detection information reporting event is triggered, sending the network quality detection information to the central agent room according to the first uplink signaling routing, and sending the network quality detection information to the central agent room.

Illustratively, when it is detected that the network quality detection information needs to be reported again, the network quality detection information can be reported to the central machine room by adopting the previously received first uplink signaling routing, so that the receiving success rate of the central machine room is also improved, and meanwhile, the network quality detection information is also sent to the central agent machine room, so that the reliability is enhanced.

The data packet routing method provided by the embodiment of the invention is characterized in that a central machine room, a central agent machine room and a plurality of front-end machine rooms are arranged in a cross-machine room communication system, the signaling interaction between the front-end machine rooms and the central agent machine room is double data and can be sent through different paths, the stability and the reliability are enhanced, the front-end machine rooms report network quality detection information to the central machine room, the central machine room determines a data routing path from a starting machine room to a destination machine room and an uplink signaling routing path according to the network quality detection information corresponding to the front-end machine rooms, the network quality corresponding to the routing path is superior to that from the starting machine room to the destination machine room, the front-end machine room receives the data routing path sent by the central machine room, and when the data packet is required to be sent, the front-end machine rooms package original data packets and related information of the data routing path into new data packets, the IP fragment packets are transmitted to a corresponding terminal machine room, when the size of a new data packet after encapsulation is predicted to be overlarge, sub-packet operation can be carried out, the IP large packet is decomposed into two IP fragment packets in a source service interface process, so that the IP fragment packets do not need to be recombined after the service interface process of the terminal machine room is unpacked, the IP fragment packets are directly transmitted to a real final destination server, and the final destination server recombines the IP fragment packets, thereby avoiding the performance consumption of IP fragment packet recombination of a service interface of the destination machine room, greatly improving the concurrency performance of processing the large packet, ensuring that the same IP packet keeps the same five-element group under the condition of fragment transmission, avoiding the problems of disorder and the like, and enhancing the transmission reliability. By adopting the technical scheme, when the front-end machine rooms transmit the data packets, the routing paths of the data packets are planned by the central machine room according to the network quality information among the front-end machine rooms, so that the network quality of the paths in the data packet transmitting process can be improved, and the probability of successfully receiving the data packets is improved.

The communication system of the cross-machine room in the embodiment of the invention can be applied to the service scene of IP interconnection communication among a plurality of machine rooms deployed by enterprises in various regions around the world, the communication system can realize the process of forwarding data packets such as service packets to a service interface of the same machine room by adopting a mode of combining BGP and PBR in a machine room server, and realizes the service-unaware access mode, namely, the communication system becomes an upper-layer service-unaware intelligent routing system, so that application services can be conveniently accessed into the intelligent routing system without additional modification, direct communication between machine rooms with network faults is avoided, other path machine rooms with good network quality can be intelligently bypassed, and reliable communication between the machine rooms is ensured.

Illustratively, the system may include two types of process modules, the first type is a Central control process Central-Controller and an agent process CC-Proxy thereof, which are deployed in a Central machine room, in order to further ensure reliability, the Central control process and the Central agent process may be respectively deployed in a Central machine room and a Central agent machine room, the Central machine room and the Central agent machine room may be located in the same city, and a metropolitan area network connection is adopted, and network communication is considered as reliable. The second type is a front-end process, which is deployed in each machine room (front-end machine room) and comprises a detection process pkgloss, a Relay forwarding process Relay and an interface service process transit-Edge. The Central control process Central-Controller can be understood as a master control center of the system, other modules or processes can report states to the Central control process, and the Central control process calculates a relay path of each machine room in real time according to the network quality of each machine room and sends the relay path to a service interface process; the CC-Proxy process of the central control agent is used as an agent of the central control process, and the signaling interaction between the central control process and the front-end process is forwarded, so that the signaling interaction between the central control process and the front-end process is duplicate data and is sent through different paths, and the reliability is improved; the detection process pkgloss is used for detecting network quality (such as packet loss rate, RTT and the like) between every two machine rooms and reporting to the central control process; the Relay forwarding process Relay forwards the received packet (i.e. the data packet received by the Relay room in the embodiment of the present invention) conforming to the predetermined format to the next hop; and the service interface process transit-Edge receives the service packet in the same machine room, encapsulates the service packet in a UDP load, forwards the service packet through a plurality of relays, finally reaches the service interface process of the target machine room of the service packet, and decapsulates the original service packet from the service interface process of the target machine room and sends the original service packet to the final target server.

Fig. 8 is an interaction diagram of a communication system according to an embodiment of the present invention. As shown in fig. 8, all the control signaling received by the central agent process from the front end is forwarded to the central control process, and all the control signaling sent by the central control process to the front end is copied and sent to the central control agent process, and the central control agent process is forwarded to the corresponding front end process, that is, all the control signaling communications through the central control agent process, the central control process and the front end process are duplicated. The detection process can detect the network quality from the computer room to all other computer rooms and report the network quality to the central control process at regular time. And the central control process calculates a path with good network quality among the machine rooms according to the acquired network quality of the machine rooms. For example, in the above example case, the packet loss rate from the machine room a to the machine room B is 10%, but there is no packet loss from the machine room a to the machine room C, and there is no packet loss from the machine room C to the machine room B, a relay path (data routing path) such as the machine room a ═ B ═ C may be calculated, and then the relay path of the machine room is sent to the service interface process of the corresponding machine room (machine room a). The service interface process declares the destination IP address to be transferred to the core switching machine by using BGP according to the transfer path, and the switch gives the packets sent to the destination IP address to the switch for processing. For the above example, the service interface process in the machine room a declares the service IPb in the machine room B to the switch, and the service interface process in the machine room a receives the packet whose destination IP is IPb, and then encapsulates the IP packet in the UDP load and adds the related information (such as the address information of the service interface process in the machine room B) of the service interface process in the final destination machine room (the destination machine room, that is, the machine room B), and sends the packet to the relay forwarding process in the machine room C, and the relay forwarding process in the machine room C parses the packet, takes out the next hop destination address as the service interface process in the machine room B, and forwards the next hop destination address to the service interface process in the machine room B, and the service interface process in the machine room B receives the packet, decapsulates the original IP packet, and obtains the original IP packet, and sends the destination service process in.

Because the front-end process is in each machine room around the world, there may be network failure between the front-end process and the machine room where the central control process is located. Under the condition of the network fault, various abnormal conditions that the detection process cannot report the network quality or the service interface process cannot receive the transfer path issued by the central control process may occur, so that the intelligent routing system cannot normally provide service for the service. Therefore, in the embodiment of the present invention, the control signaling interacting between the central control process and the front-end process can be further made to solve the transmission when the network fails through the relay forwarding path provided by the central control process, and the reliability is increased through another control signaling forwarded by the central control agent process.

The control signaling (which may be called downlink control signaling) sent from the central control process to the front end can set a preset value in the TOS field of the IP header, and as the core switch uses PBR configuration, an IP packet with the TOS field set as the preset value is received, and the IP packet is forwarded to the service interface process of the machine room by default. And the service interface process receives the IP packet with the TOS field as the preset value, encapsulates the IP packet in UDP load, adds related information such as the final destination machine room service interface process and the like, and finally reaches the front-end process of each machine room through a relay forwarding process.

Fig. 9 is a schematic diagram of a transmission process of a downlink control signaling according to an embodiment of the present invention, and as shown in fig. 9, a downlink signaling routing path corresponding to the downlink control signaling is from a machine room 1 to a machine room 2, and then to a machine room 4 (a starting machine room of a data routing path). The central control process of the machine room 1 sends the control signaling to the central control agent process of the machine room n, the central control agent process forwards the control signaling to the front-end process of the machine room 4, the central control process of the machine room 1 sends the control signaling with the preset value TOS to the core switch of the machine room 1, the core switch of the machine room 1 forwards the control signaling to the service interface process of the machine room 1, the service interface process of the machine room 1 sends the control signaling encapsulated in the UDP to the relay forwarding process of the machine room 2, the relay forwarding process of the machine room 2 forwards the encapsulated control signaling to the service interface process of the machine room 4, and the service interface process of the machine room 4 sends the de-encapsulated control signaling to the front-end process of the machine room 4. Therefore, the control signaling sent to the front end by the central control process is a duplicate packet with different paths, and the reliability of control signaling transmission can be ensured.

Communication from the front-end process of each machine room to the central control process, that is, a control signaling (may be called an uplink control signaling) sent from the front-end process of the machine room to the central control process, announces a server IP where the central control process is located to the core switch through a service interface process of the machine room, and thus, when a network fails, the central control process can reach the machine room around other machine rooms.

Fig. 10 is a schematic diagram of a transmission process of an uplink control signaling according to an embodiment of the present invention, and as shown in fig. 10, a routing path of an uplink signaling corresponding to the uplink control signaling is from a machine room 4 (a front-end machine room that needs to report network quality detection information) to a machine room 2 and then to a machine room 1. The front-end process of the machine room 4 sends the control signaling to the central control agent process of the machine room n, the central control agent process of the machine room n forwards the control signaling which takes the destination IP as the central control process to the central control process of the machine room 1, meanwhile, the front-end process of the machine room 4 sends the control signaling which takes the destination IP as the central control process to the core switch of the machine room 4, the core switch of the machine room 4 forwards the control signaling to the service interface process of the machine room 4, the service interface process of the machine room 4 sends the control signaling encapsulated in the UDP to the relay forwarding process of the machine room 2, the relay forwarding process of the machine room 2 forwards the control signaling to the service interface process of the machine room 1, and the service interface process of the machine room 1 sends the control. Therefore, the control signaling from the front end to the central control process is a duplicate packet with different paths, so that the reliability of control signaling transmission can be ensured.

Fig. 11 is a block diagram of a packet routing apparatus according to an embodiment of the present invention, where the apparatus may be implemented by software and/or hardware, and may be generally integrated in a central computer room in a communication system across computer rooms, such as a server, and may perform packet routing by implementing a packet routing method.
