The embodiment of the disclosure provides a traffic forwarding method, which comprises the following steps:
forwarding, by a first routing unit, a first session traffic originating from a first target IP address to a second routing unit according to a first routing path generated according to first configuration information, so that the second routing unit forwards the first session traffic to a second target IP address, wherein a plurality of routing paths are included between the first routing unit and the second routing unit, and each routing path includes a session holding device;
and forwarding, by the second routing unit, a second session traffic originating from the second target IP address to the first routing unit according to a second routing path generated according to second configuration information, so that the first routing unit forwards the second session traffic to the first target IP address, where the first session traffic and the second session traffic belong to the same session, and communication nodes of the first routing path and the second routing path are the same.
Fig. 1 schematically illustrates an application scenario diagram of a traffic forwarding method, apparatus, device, medium and program product according to an embodiment of the present disclosure.
As shown in fig. 1, a system architecture 100 according to this embodiment may include a first routing unit 101, a second routing unit 102, a first session holding device 103, and a second session holding device 104.
The first routing unit 101 and the second routing unit 102 may be various types of routing devices, and are used for connecting two or more networks, functioning as a gateway between the networks, and performing storage and packet forwarding processing on data packets between different networks.
The first session holding device 103 and the second session holding device 104 may be used to keep a certain session (same source IP and destination IP, homologous port, destination port, etc.) state on the device, so that incoming and outgoing traffic is passed through, or to find backhaul traffic, which may be various types of firewalls, IPs, etc., for example.
In the application scenario of the present disclosure, the first routing unit 101 and the second routing unit 102 may analyze destination addresses of data packets transmitted from various different types of networks according to different protocols, for example, an ethernet protocol used by a certain local area network, a TCP/IP protocol used by the internet, and convert addresses of non-TCP/IP networks into TCP/IP addresses, or vice versa; and then transmitting each data packet to a designated position according to the optimal route according to the selected routing algorithm.
According to an embodiment of the present disclosure, the data forwarding is performed in the above scenario, for example, communication may be established between a communication device located in the routing area 1 and a communication device located in the routing area 2 and having a plurality of IP addresses, and the traffic may be originated from a first IP destination address located in the routing area 1, and in the case where the traffic is forwarded to the first routing unit 101, the first routing unit 101 forwards the traffic data to the second routing unit 102 according to a routing path (for example, may be a first path routed through the first session holding device 103 or a second path routed through the second session holding device 104) generated according to the configuration information according to a preset routing algorithm or routing policy, so that the second routing unit 102 forwards the traffic to the second IP destination address in the routing area 2. Since the first path and the second path are connected in series with the session holding device, the backhaul traffic (originating from the second IP destination address in the routing area 2 and forwarding to the first destination IP address in the routing area 1) needs to pass through the same session holding device.
It should be appreciated that the number of first routing unit 101, second routing unit 102, first session holding device 103 and second session holding device 104 in fig. 1 is merely illustrative. There may be any number of routing units and session holding devices, as desired for implementation.
The flow forwarding method of the disclosed embodiment will be described in detail below with reference to fig. 2 to 9 based on the scenario described in fig. 1.
FIG. 2 schematically illustrates an application scenario diagram of a related art implementation of link high availability through routing loads; fig. 3 schematically illustrates an application scenario diagram of a traffic forwarding method according to an embodiment of the present disclosure.
The router/switch works at the three-layer routing level, where the high availability of links is usually achieved by routing the load, and the route determines which link to walk by the destination address of the route when forwarding. When two links are loaded, the problem of inconsistent round-trip paths exists.
As shown in fig. 2, from a to D, there are two paths a→b→d and a→c→d, and similarly, one session is bidirectional, and d→b→a and d→c→a can be returned, and since the two paths are loads, there is a 50% probability in each of the two paths in traffic selection, and there is a case that the back and forth paths are inconsistent. In this case, as shown in the scenario of fig. 3, if devices requiring session maintenance are connected in series in a path, since the devices requiring session maintenance need that the traffic round-trip paths are all maintained on one device, how to maintain the consistency of the round-trip paths is a problem to be solved.
In order to solve the above problems, for example, the following method can be adopted:
for example, the main and standby devices can be distinguished by the X-A device and the X-B device which need to be maintained in a session, the two lines are not loaded, paths where the X-A device and the X-B device are located are respectively a main path and a standby path, a default flow forwarding path is the main path, and the back-and-forth paths are kept consistent. For example: setting X-A as main equipment, setting X-B as slave equipment, setting default flow forwarding path as X-A main path on route exchange A, setting default flow forwarding path as X-A main path on route exchange D, switching to X-B standby path if main path is unavailable.
For example, the state synchronization can be performed between the devices X-A and X-B, so that the X-B device and the X-A device learn the state table maintained by the session, and the necessary conditions for forwarding are provided on both sides, thereby achieving the capability of forwarding on both sides.
In the process of realizing the present disclosure, the following technical defects are found to exist in the method:
after the two devices distinguish the main device from the standby device, the performance of the devices is lost, and the standby device does not perform calculation and forwarding, so that the overall efficiency is reduced. State synchronization can make it possible for devices to interact when they encounter a BUG. For a session problem that enables the device X-A to crash and restart, the session problem is also retransmitted to X-B, so that X-B and X-A restart together, and the overall redundancy is affected. Meanwhile, the A and the B maintain the same session table, when the session bursts, the two devices can have the session overstock, and the two devices are affected.
In view of this, embodiments of the present disclosure provide a traffic forwarding method.
Fig. 4 schematically illustrates a flow chart of a traffic forwarding method according to an embodiment of the present disclosure.
The method of the embodiments of the present disclosure is described below with reference to fig. 4 and fig. 3 described above.
As shown in fig. 4, the traffic forwarding of this embodiment includes operations S401 to S402.
Forwarding, by the first routing unit, the first session traffic originating from the first target IP address to the second routing unit according to the first routing path generated according to the first configuration information so that the second routing unit forwards the first session traffic to the second target IP address, wherein a plurality of routing paths are included between the first routing unit and the second routing unit, each routing path including the session maintenance device;
in operation S402, forwarding, by the second routing unit, the second session traffic originating from the second target IP address to the first routing unit according to the second routing path generated according to the second configuration information, so that the first routing unit forwards the second session traffic to the first target IP address, wherein the first session traffic and the second session traffic belong to the same session, and communication nodes of the first routing path and the second routing path are the same.
According to an embodiment of the present disclosure, the first routing unit and the second routing unit (the routing switch a and the routing switch D shown in fig. 3) may be various types of routing devices for connecting two or more networks, functioning as a gateway between the networks, and performing storage and packet forwarding processing on data packets between different networks. The first routing unit is located in the routing area 1, the first target IP address is any IP address in the routing area 1, the second routing unit is located in the routing area 2, and the second target IP address is any IP address in the routing area 1.
In an application scenario of the present disclosure, communication is established between a first target IP address located in routing area 1 and a second target IP address located in routing area 2 to communicate traffic data. A plurality of routing paths may be included between the first routing unit and the second routing unit, each routing path including a session maintenance device. For example, as shown in fig. 3, two routing paths may be included between the first routing unit and the second routing unit, where each path is connected in series with a session maintenance device X-a device and an X-B device, respectively. According to an embodiment of the present disclosure, the session maintaining device is configured to keep a certain session (same source IP and destination IP, homologous port, destination port, etc.) state on the device continuously, so that incoming and outgoing traffic is passed through, or backhaul traffic is found, which may be various types of firewalls, IPs, etc., for example.
According to an embodiment of the present disclosure, in the case where, in the above scenario, traffic originating from the first IP destination address in the routing area 1 is forwarded to the first routing unit (routing switch a), the first routing unit forwards traffic data to the second routing unit (routing switch D) according to the first routing path (for example, one of the two routing paths, X-a path and X-B path, shown in fig. 3) generated according to the first configuration information, so that the second routing unit forwards traffic to the second IP destination address in the routing area 2.
In accordance with an embodiment of the present disclosure, in the case where backhaul traffic (originating from the second IP destination address in routing area 2) is forwarded to the second routing unit, the second routing unit forwards traffic data to the first routing unit (routing switch a) in accordance with the second routing path (which may be, for example, one of the two routing paths, X-a path and X-B path shown in fig. 3) generated from the second configuration information, so that the first routing unit forwards traffic to the first IP destination address in routing area 1.
According to an embodiment of the present disclosure, the session holding device is included in each of the routing paths between the first routing unit and the second routing unit, and thus, the paths of the outbound traffic and the inbound traffic paths need to be kept consistent, i.e. the communication nodes of the first routing path and the second routing path are the same, and the first routing path and the second routing path both pass through the same session holding device (in the X-a device or the X-B device).
According to an embodiment of the disclosure, the first configuration information is generated by a first routing unit according to a preset routing policy, the second configuration information is generated by a second routing unit according to a preset routing policy, and in order to keep the round-trip paths consistent, the first configuration information may be generated according to a routing policy based on a source address; the second configuration information is generated according to a destination address based routing policy.
The embodiment of the disclosure provides a method for sharing multiple paths and guaranteeing consistency of back and forth paths based on IP scheduling, which ensures that traffic is reserved on both sides of an IP layer load (wherein for the same session, the routing paths pointed by the routing configuration information of both ends are kept consistent) by pre-configuring the routing configuration information of routing switching equipment at both ends, and the consistency of the back and forth paths of the same session is realized by forwarding the traffic according to the routing paths determined by the configuration information. According to the flow forwarding method, the flow is loaded in the network layer, the configuration is simple, the pressure of equipment needing to be maintained by a session is reduced, new management and control equipment is not needed, the flow is easy to balance, the equipment maintained by the session is not interconnected and synchronous, the probability of mutual influence is reduced, the problems that forwarding efficiency is low and two pieces of equipment maintained by the session are mutually influenced in the prior art are solved, and the high availability of a system architecture is improved.
According to an embodiment of the present disclosure, in the above method: the first routing unit and the first target IP address belong to a first routing segment area, and the second routing unit and the second target IP address belong to a second routing segment area. The first routing segment area and the second routing segment area are routing areas of two communication ends (source end and destination end). In the scenario shown in fig. 3, the first routing unit is located in the routing area 1, the first target IP address is any IP address in the routing area 1, the second routing unit is located in the routing area 2, and the second target IP address is any IP address in the routing area 1.
The first configuration information includes: mapping relation between each IP address in the first route network section area and the route path; the second configuration information includes: mapping relation between each IP address and the routing path in the second routing network segment area. The first configuration information can be used for generating a routing path corresponding to each IP address in the first routing network segment area, and the second configuration information can be used for generating a routing path corresponding to each IP address in the second routing network segment area so as to forward traffic according to the routing paths.
According to the embodiment of the disclosure, first configuration information is generated according to a preset routing strategy through a first routing unit, second configuration information is generated according to the preset routing strategy through a second routing unit, and in order to keep the round-trip paths consistent, the first configuration information is generated according to the routing strategy based on the source address; the second configuration information is generated according to a destination address based routing policy.
In the scenario shown in fig. 3, policy routing (source address-based routing policy) is configured on the routing switch a, and normal routing (destination address-based routing policy) is configured on the routing switch D. For example, the first configuration information set at the route switch a may be: traffic originating from IP1, walks the X-a path; meanwhile, the second configuration information configured on the routing switch D may be: the destination is the flow of IP1, the X-A path is walked, the consistency of the round-trip flow path under the same session can be ensured by configuring the routing information at the two ends of the communication according to different routing strategies (the first configuration information is generated according to the routing strategy based on the source address, and the second configuration information is generated according to the routing strategy based on the destination address) and forwarding the flow according to the routing path determined by the configuration information.
According to an embodiment of the present disclosure, in the foregoing traffic forwarding method, in configuring the first configuration information and the second configuration information for the first routing unit and the second routing unit, respectively, it is necessary to determine which end is configured with a policy route, so that configuration information of the one end is generated according to a routing policy based on a source address, and at the same time, a normal route is configured at the other end, so that configuration information of the other end is generated according to a routing policy based on a destination address. Therefore, it is necessary to distinguish between the upper access route and the lower access route and select an appropriate route splitting network segment.
According to an embodiment of the present disclosure, it may be selected to configure policy routing at the end with a smaller number of routing segments, i.e. if the first configuration information is generated by the first routing unit (in the first routing segment area) according to the source address based routing policy, and the second configuration information is generated by the second routing unit (in the second routing segment area) according to the destination address based routing policy, then the precondition is that: the number of routing segments in the first routing segment area is less than the number of routing segments in the second routing segment area.
In the scenario shown in fig. 3, in the network environment, the IP address segment set of the routing area 1 and the IP address set of the routing area 2 are necessarily not coincident, otherwise, the related traffic does not pass through the following area.
According to the embodiment of the disclosure, the policy route is configured on the side with few route entries, for example, assuming that there are 10 route segments in the route area 1 and 100 route segments in the area 2, the policy route is configured in the route exchange a in the route area 1, so that the configuration quantity can be effectively reduced, and the operation and maintenance difficulty can be reduced.
According to the embodiment of the present disclosure, since the mapping relationship between each IP address and the routing path in the relevant routing segment area is specified in the first configuration information and the second configuration information, in configuring the first configuration information and the second configuration information for the first routing unit and the second routing unit respectively, a traffic splitting manner needs to be determined, specifically:
The first configuration information is related to session characteristics of each IP address in the first routing network segment area in a preset historical time period and sensitive parameters of the session maintenance equipment;
the second configuration information is related to session characteristics of each IP address in the second routing segment area for a preset history period and sensitive parameters of the session maintenance device.
That is, in configuring the first configuration information and the second configuration information, a path of each IP address is determined according to session characteristics of the IP address in a preset history period and sensitive parameters of the session holding apparatus.
In the scenario shown in fig. 3, it is assumed that there are 10 routing segments in routing area 1, and 100 routing segments in area 2, policy routing is performed on routing switch a, and normal routing path is performed on routing switch D. Then 10 routes in region 1 need to be split. Since the configuration of the routing policy is determined based on a specific IP or IP segment, session characteristics (such as more frequent new sessions, longer session duration, etc.) of each IP segment over a period of time need to be collected, and according to the session characteristics of each IP segment, N sets of address segments are allocated according to the number N of paths between the routing switch a and the routing switch D in combination with the sensitive parameters of the session maintenance device, where the session characteristics of the addresses in each set are approximately average. For example, 10 of the routing segments in routing area 1 have 3 IP-associated X-A paths and the remaining 7 IP-associated X-B paths.
The sensitive parameter refers to what specification of attribute the session keeping device X-a is sensitive to, that is, the sensitive parameter is an attribute that the session keeping device X-a is most likely to reach a performance bottleneck in daily use. For example, a session maintenance device can achieve line speed forwarding on traffic, but has a bottleneck in the number of sessions, which is a sensitive parameter. For another example, the firewall is sensitive to the number of new sessions and the number of continuous sessions, and the number of new sessions and the number of continuous sessions are sensitive parameters of the firewall.
According to an embodiment of the present disclosure, the above scenario is, for example: if a routing path of an IP in the routing area 1 is required to be configured on the routing exchange a, session characteristics of the IP in the past period of time are collected, for example, the number of newly-built sessions of the IP is more frequent, and the IP can be set to share one routing path independently or associate a smaller number of IPs with the routing path corresponding to the IP in combination with the routing exchange a to be sensitive to the sensitive parameter of the number of newly-built sessions.
According to embodiments of the present disclosure, the sensitive parameter key attribute of the session maintenance device may be any parameter of interest between 4-7 layers in the OSI7 layer model, including, for example, but not limited to: traffic bandwidth, number of new sessions, number of persistent sessions, number of packet forwarding, etc.
According to the embodiment of the disclosure, the flow splitting mode is determined according to the session characteristics of each IP address and in combination with the sensitive parameters of the session holding equipment, so that the sensitive characteristics of the flow holding equipment are fully considered, the flow splitting mode is more reasonable, and the phenomena of flow congestion, session interruption and the like caused by unreasonable flow distribution in the communication process are avoided.
According to an embodiment of the present disclosure, the first configuration information further includes a mapping relationship between each IP address in the first routing segment area and the backup routing path; the second configuration information includes a mapping relationship between each IP address in the second routing segment area and the backup routing path.
According to the embodiment of the present disclosure, by the above manner, a standby path may be set for each routing path corresponding to each IP, for example, in the scenario shown in fig. 3, it is assumed that there are 10 routing segments in the routing area 1, 100 routing segments in the area 2, a policy routing is performed on the routing switch a, and a normal routing path is performed on the routing switch D.
On the route exchange D, 10 routes on the route exchange A are split, the flow is split according to the required proportion, one part of the destination IP section is configured with a route path main path to point to X-A, the standby path to point to X-B, the other part of the destination IP end is configured with a route path main path to point to X-B, and the standby path to point to X-A. The method of traffic splitting may refer to the method of determining the traffic splitting method according to the session characteristics of each IP address and the sensitive parameters of the session maintenance device in the foregoing embodiment. Meanwhile, strategy routes are configured on the route exchange A according to a preset proportion, a part of strategy route configuration of the source IP section is directed to X-A, the standby path is directed to X-B, and the other part of strategy source IP section configuration route main path is directed to X-B, and the standby path is directed to X-A according to a required proportion.
According to the embodiment of the disclosure, by setting the backup paths for the routing paths corresponding to each IP respectively, high availability of the paths can be realized, and under the condition that the main path is unavailable, traffic is conveniently switched to the backup paths, so that the reliability of the session is improved.
According to the embodiments of the present disclosure, the traffic forwarding method described in the embodiments of the present disclosure is not limited to the application scenario of the system architecture shown in fig. 3, and may be applied to scenarios of various system architectures. For example: a case where the first routing unit or the second routing unit is provided with a plurality of, a case where each routing path includes a plurality of session holding devices, and the like.
Fig. 5 schematically illustrates another application scenario diagram of a traffic forwarding method according to an embodiment of the present disclosure. In the scenario shown in fig. 5, more than two routing paths may be included between the first routing unit and the second routing unit, where each path is connected in series to a session-maintaining device.

In the scenario shown in fig. 6, the first routing unit and the second routing unit are provided in plurality, i.e. there is redundancy in the routing switches a and D.
Fig. 7 schematically illustrates yet another application scenario diagram of a traffic forwarding method according to an embodiment of the present disclosure.
