Description

Message processing method and device
Technical Field
The embodiment of the invention relates to the technical field of communication, in particular to a message processing method and device.
Background
At present, operators usually use Provider Backbone Bridge (PBB) technology to provide two-layer tunnel service for users, and referring to fig. 1, a Backbone Edge Bridge (BEB) device performs PBB encapsulation on a received message from a user network (customer network), and adds a Backbone MAC (Backbone MAC, B-MAC) and a Backbone VLAN (Backbone VLAN, B-VLAN) allocated by the operators into the message to form a PBB message; and sending the PBB message to a Backbone network core bridge (BCB), and forwarding the PBB message in a Provider Backbone Bridge (PBBN) by the BCB according to the B-MAC and the B-VLAN. For the PBB message sent by the BCB to the BEB, the BEB also carries out decapsulation and then sends the decapsulated PBB message to the user network.
On the BCB side, a large number of various messages can be received, and the messages can be forwarded from the BCB to the BEB, but the messages are not all messages required by the BEB; moreover, for the BCB, a port (such as the port D1 in fig. 1) where the BCB is connected to the BEB may have congestion due to a large amount of packet forwarding, and the congestion may cause the BCB to discard a part of the packet, which may further cause the BEB to fail to receive the required packet. In order to reduce the impact of message congestion, in the prior art, it is attempted to set a permitted VLAN on the BCB side, where the permitted VLAN is set according to the VLAN channel of the BVLAN created on the BEB, so it is equivalent to drop the message of the BLAN on the non-BEB. This approach reduces the instances of port congestion to some extent, but still presents problems: for example, it may be possible to allow a portion of the same message as the BVLAN but with a different I-SID to be sent to the BEB, which is not required; or, if the BEB device is used to forward a normal data packet, the normal data packet will be discarded because it is not transmitted through the BVLAN; these conditions all affect the reception of the target message required by the BEB, and from the BEB perspective, the message transmission efficiency of the current transmission network is low, that is, the target message required by the BEB cannot be quickly transmitted to the BEB.

Detailed Description
In order to improve the message transmission efficiency of a Provider Backbone Bridge (PBB), so that the BCB can quickly send a target message required by the BEB to the BEB, and a port on the BCB side is not excessively congested, the main idea of the scheme designed in the embodiment of the present invention may be seen in fig. 2, where the BEB sends its message configuration information to the BCB, where the message configuration information is used to limit characteristics corresponding to the target message to be received by the BEB.
Examples are as follows: assuming that a certain BEB is configured with a VSI (Virtual Switch Interface) instance (the instance includes an I-SID and a B-VLAN having a set of corresponding relationships), the VSI instance is bound to the port e1 in fig. 2, and the port e1 is a port used by the BEB to connect to the BCB, it means that the BEB receives only the packet transmitted from the BCB and satisfying the I-SID and the B-VLAN at the same time at the port e1, and the packet may be referred to as a target packet (i.e., a packet that the BEB wants to receive). The BEB may send the I-SID and B-VLAN, which may be referred to as message configuration information, to the BCB.
On the BCB side, selecting a message meeting the requirement of message configuration information from a large number of received data messages according to the message configuration information transmitted by the BEB, wherein the message is a target message which is required to be received by the BEB; and the BCB sends the target message to the BEB.
Examples are as follows: BCB receives two messages, each message carries I-SID and B-VLAN, then BCB compares the information with message configuration information transmitted by BEB received in advance, wherein I-SID and B-VLAN of one message are the same as I-SID and B-VLAN in the message configuration information, BCB confirms that the message is a target message to be received by BEB, and sends the target message to BEB through a port c1 in figure 2; and the B-VLAN of the other message is the same as the B-VLAN in the message configuration information, but the I-SID of the two messages is different, so that the BCB can determine that the message is not the target message to be received by the BEB according to the I-SID of the two messages, and discards the message.
The advantages of the above-described embodiment of the invention can be illustrated by comparison with the prior art as follows: suppose that the BCB receives a large number of data packets, taking three data packets as an example, the I-SID and B-VLAN of the first packet are the same as the corresponding information in the above-mentioned packet configuration information, the I-SID of the second packet is the same as the packet configuration information but different from the B-VLAN, and the B-VLAN of the third packet is the same as the packet configuration information but different from the I-SID. Then, if the messages are filtered by the B-VLAN according to the prior art, and only the B-VLAN is sent to the BEB identically, the first message and the third message are sent to the BEB, and the second message is discarded; in this case, port c1 of BCB may be congested due to more packets, and the third packet is not the packet intended by BEB; however, if the scheme of the embodiment of the present invention is adopted, the BCB will only send the first packet to the BEB, which not only further reduces the number of packets at the port c1 and alleviates the congestion condition, but also accurately sends the target packet required by the BEB to the BEB, which will improve the packet transmission efficiency.
Based on the above-mentioned technical idea of the embodiment of the present invention, as follows, a specific implementation of the embodiment of the present invention is described in detail, and with reference to fig. 3, the method shown in fig. 3 may include the following steps:
301. the BEB starts the intelligent anti-congestion function.
If the BEB can perform the above processing, for example, the BEB sends its message configuration information to the BCB, so that the BCB performs message filtering accordingly, this may be referred to as "intelligent anti-congestion function of the BEB". In specific implementation, an optional configuration can be set for whether the BEB starts the intelligent congestion prevention function, and when the BEB is not configured with the intelligent congestion prevention function, the BEB is the same as the common BEB and does not send message configuration information to the BCB; the flow of embodiments of the present invention may be performed when the BEB configures the intelligent anti-congestion function. The following of this embodiment is the message processing flow described on the basis that the BEB starts the intelligent congestion prevention function.
Of course alternatively, the BEB may be directly configured to have an intelligent anti-congestion function.
302. The BEB obtains the message configuration information of the BEB.
In this embodiment, the message configuration information of the BEB itself is used to define the feature corresponding to the target message to be received by the BEB. The message configuration information may include: and the backbone network service instance of the target message identifies the I-SID and the corresponding BVLAN. Referring collectively to fig. 4, the BEB may include a plurality of ports, such as port e1, port e2, and port e3, e1 being ports for connecting BCBs; the BEB configures a VSI instance, the VSI instance comprises a B-VLAN and an I-SID which have corresponding relations, the BEB binds the VSI instance with a port e1, namely the BEB is used for indicating that the port e1 can only receive messages which simultaneously carry the B-VLAN and the I-SID in the VSI instance, and the messages meeting the condition are called as target messages of the BEB.
In another embodiment, the message configuration information may further include: the bridge MAC address of the BEB equipment and message scheduling parameters corresponding to different types of messages, wherein the message scheduling parameters are used for expressing the scheduling priority and/or the weight index of the different types of messages.
Examples are as follows: assuming that there are three types of messages, that is, a PBB message unicast to the BEB, a PBB message multicast or broadcast to the BEB, and a non-PBB message, the message scheduling parameters of the three types of messages may be configured on the BEB, for example, the message scheduling parameters of this embodiment may include sp (scheduling priority) and/or weight (Weighted value) used in Weighted Round Robin (WRR) scheduling, that is, a weight parameter; for example, if the queue a is set to sp, the queue B is set to 15, and the queue C is set to 1, then if the bandwidth of the C1 port of BCB is 100M in total, and all three messages of A, B, C send 50M traffic, according to the above message scheduling parameters, the messages should be preferentially allocated to the queue a50M, and the remaining 50M bandwidth, the queue B and the queue C are scheduled according to the ratio of 15:1, that is, the queue B is divided into about 47M, and the queue C is divided into about 3M.
It should be noted that, the setting of the message scheduling parameters of the three messages is only an optional manner, and in a specific implementation, different scheduling parameters may be set according to actual transmission needs, for example, when a "non-PBB message" is more important for a BEB than a "PBB message multicast or broadcast to a BEB", a weight parameter of the "non-PBB message" may also be set to 15, and a weight parameter of the "PBB message multicast or broadcast to the BEB" is set to 1 (this is an example, and a value of the weight parameter in the specific implementation may be changed according to an actual situation). In addition, the setting of the message scheduling parameter may be global setting or port setting. With reference to fig. 4, the global setting means that all ports (including e1, e2, and e3) of the BEB can be set to the same message scheduling parameter, for example, when the port e2 receives a message, the setting is also according to the above-described embodiment; while port down setting means that, for example, only port e1 is set with the scheduling arrangement described above, the setting of the message scheduling at port e2 may be different from port e 1.
In another embodiment, the message configuration information may further include: and the PBB mode information is used for indicating that the target message is a PBB message or a non-PBB message.
Examples are as follows: a configurable option can be set on the BEB device, namely whether a certain port of the BEB is configured to be opened in a 'PBB mode'; if the PBB mode is set, the BEB is only used as the BEB equipment, namely only the PBB message is received; if the non-PBB mode is configured, the BEB can receive both PBB messages and non-PBB messages.
In this step, the BEB acquires the above-mentioned message configuration information, where the BEB may be configured to be provided with a Link Layer Discovery Protocol (LLDP) module, and the LLDP module may collect the message configuration information of the BEB device at the local end, assemble the information into type/length/value (TLV) information, and encapsulate the TLV information in the LLDP message.
303. And the BEB sends the message configuration information to the BCB.
In this embodiment, the BEB sends an LLDP message to the BCB, where the LLDP message carries the message configuration information acquired by the BEB. In specific implementation, the BEB may send the LLDP packet periodically, and when the packet configuration information is updated, the BEB may immediately send the updated packet configuration information to the BCB.
304. And the BCB generates a message filtering strategy at the port according to the received message configuration information.
Referring to fig. 5 in combination, after receiving the message configuration information sent by the BEB, the BCB may generate a message filtering policy according to the information, where the message filtering policy is used for enabling the BCB to select a target message required by the BEB from the received massive data messages. For example, the message filtering policy may be recorded in the form of an Access Control List (ACL).
Because the ACL is a common method for filtering messages, the specific list of the ACL in this embodiment will not be listed, and only the possible setting conditions of the ACL are described briefly: for example, it may be configured to "discard the message if the I-SID and the B-VLAN do not hit information in the message configuration information at the same time, that is, are not identical to the I-SID and the B-VLAN in the message configuration information," or configured to "discard the message if the message is a non-PBB message," and so on, and no further enumeration is performed. In this step, the BCB generates the ACL rule according to the packet configuration information, for example, if the packet configuration information is "PBB mode is" 1 "(assuming that 1 indicates that only the PBB packet is received and 0 indicates that the non-PBB packet can be received)", the above-exemplified ACL rule "can be generated by the BCB" if the packet is a non-PBB packet, the packet is discarded ".
In addition, the message filtering policy generated by the BCB may be bound to the port, for example, referring to fig. 5, assuming that the BCB includes three ports, where the port c1 is a port for connecting with the BEB, and the port c3 is a port for connecting with other equipment (possibly another BEB), the above message filtering policy may be bound to the port c1, which is equivalent to issuing the ACL to the port c1, only the message sent to the port c1 needs to be filtered according to the ACL, and the message sent from the port c3 may not be filtered according to the ACL.
305. The BCB receives the message.
In this step, the message received by the BCB is a message transmitted from the PBBN network in fig. 1, and may be transmitted from another BCB in the PBBN. The received messages include multiple message types, such as PBB messages and non-PBB messages, unicast messages or multicast messages, and the like.
306. And the BCB filters the message according to the message filtering strategy to obtain a target message.
In step 305, the BCB receives a large number of various data packets with a large number of types, and in this step, the BCB filters the packets according to the set packet filtering policy, selects a target packet that the BEB wants to receive from the large number of packets, and may discard other packets to prevent packet congestion.
307. The BCB sends the target message to the BEB.
It should be noted that, in this step, when the BCB sends the selected target packet to the BEB, the above-mentioned packet filtering policy may be used; for example, as described above, the message filtering policy is generated according to the message configuration information, that is, the message filtering policy may include message scheduling parameters of different types of messages, and then the messages may be sent according to the parameters when being sent to the BEB, for example, the queue a with the parameters set to sp performs priority scheduling, and the queue B and the queue C perform scheduling according to the ratio of the WRR scheduling weight parameter.
Specifically, how the BCB selects and sends the target packet according to the packet filtering policy is specifically described in the following embodiments.
Further, after receiving the message configuration information sent by the BEB, if the message configuration information sent by the BEB is not received again within the preset time, the BCB clears the message configuration information received this time.
How the BCB selects a target packet and transmits the target packet according to the packet configuration information transmitted by the BEB will be described in detail below, i.e., steps 306 and 307 in fig. 3. The method comprises the following specific steps:
firstly, the message filtering policy generated by the BCB side according to the message configuration information may include the following:
rule one is as follows: for the received message, if the I-SID and the B-VLAN in the message configuration information are not hit at the same time, the message is not belonged to the BEB, and the message is discarded;
rule two: for the received message, according to the 'PBB mode' set in the message configuration information, if the value of the PBB mode is '1', only allowing the PBB message to be sent to the BEB, and discarding all non-PBB messages; if the value of the PBB mode is '0', allowing the PBB message and the non-PBB message to pass through; the present embodiment assumes that the PBB mode set by the message configuration information is "0";
rule three: for the received message, according to the destination address in the message, if the destination address is the bridge MAC of the BEB set in the message configuration information, the message is indicated to be unicast to the BEB; if the destination address is a broadcast address or a multicast address, indicating that the destination address is a message broadcasted or multicasted to the BEB; and different message scheduling parameters are set for the 'unicast message to the BEB', 'broadcast or multicast message to the BEB' and 'non-PBB message', and different types of messages are transmitted with different scheduling priorities. In this embodiment, it is assumed that the message scheduling parameter set by the message configuration information is "the parameter of the PBB message unicast to the BEB is sp, the parameter of the PBB message multicast or broadcast to the BEB is 15, and the parameter of the non-PBB message is 1"; the above "scheduling priority" means that different scheduling resources are configured for different types of packets according to the configured packet scheduling parameters, for example, if the bandwidth of the C1 port of the BCB is 100M in total, and all three packets A, B, C send 50M traffic, the packets should be preferentially allocated to the queue a50M, the remaining 50M bandwidth, and the queues B and C are scheduled according to a ratio of 15:1, that is, the queues B are divided into about 47M and the queues C are divided into about 3M, as described above.
Then, it is assumed that the BCB side of the present embodiment will receive various types of packets as described above, and these packets may be congested at port c1 of the BCB side; the BCB may filter the packet according to the following procedure, solve the congestion problem, and improve the packet transmission efficiency, see fig. 6, including the following processing, but not limiting the execution sequence of the steps:
601. BCB discards the I-SID and B-VLAN if the I-SID and B-VLAN in the message configuration information are not hit (hit, namely are the same) at the same time;
602. the BCB allows the PBB message and the non-PBB message to pass through according to the second rule, namely the PBB message and the non-PBB message are not discarded; the PBB message is a message for hitting I-SID and B-VLAN;
603. BCB obtains the destination address in the message and determines the message type by comparing the destination address with the bridge MAC of BEB in the message configuration information;
specifically, for a received message, according to a destination address in the message, if the destination address is a bridge MAC of a BEB set in message configuration information, it indicates that the message is a unicast message to the BEB; if the destination address is a broadcast address or a multicast address, the destination address is a message broadcast or multicast to the BEB.
604. The BCB classifies different types of messages into corresponding message queues to be transmitted;
specifically, the BCB may put the unicast message to the BEB into the queue a; the messages broadcasted or multicasted to the BEB are classified into a queue B; and classifying the non-PBB message into a queue C. Referring to fig. 7, the three message queues described above are shown.
In an embodiment, the manner of classifying different types of messages into different queues may be to set a value of an identification field in the message, so as to classify the message by changing the value; for example, the priority of dot1p in the message can be changed according to the message matching the ACL field to enter different queues.
605. And the BCB transmits the messages to the BEB according to the message scheduling parameters corresponding to the different types of messages and different scheduling priorities.
Referring to fig. 7, the different lengths of the arrow lines on the right side of the message queue represent the scheduling priority of the message queue, that is, the priority of the "unicast message to BEB" is the highest, and the scheduling resource requirement of the type of message will be satisfied preferentially; the priority of the 'message broadcast or multicast to BEB' is the lowest, and the scheduling resources in corresponding proportion are distributed according to the proportion setting of the scheduling parameters corresponding to the type of the message, wherein the priority of the 'non-PBB message' is the lowest. This scheduling order is set according to the message scheduling parameters set by the above three rules.
The application scenarios of such packet scheduling priorities are, for example: when BCB is congested, the aggregated message includes the above three types of messages, and then congestion is likely to cause message loss, so a message relatively important for BEB should be delivered preferentially, and "unicast to BEB message" is most important because the message is definitely for BEB, "broadcast or multicast to BEB message" is likely not to belong to BEB, and therefore is of the second importance, and so on. The BCB will, according to the example described above, preferentially allocate scheduling resources for "unicast to BEB messages" so that the most important messages are preferentially delivered to the BEB, which reduces the possibility of important messages being lost due to congestion when congestion occurs, and even if the important messages are lost, only the less important messages may be lost, which has less impact on the BEB.
According to the message processing method provided by the embodiment of the invention, the BEB sends the characteristics of the target message to be received by the self side to the BCB, so that the BCB selects the corresponding target message to be transmitted to the BEB according to the characteristic information, the message requirement of the BEB side can be met, the message required by the BEB is rapidly transmitted to the BEB, and the message transmission efficiency is improved; meanwhile, the bandwidth occupation of useless messages is eliminated, and the effective bandwidth of a BCB port is saved.
Fig. 8 is a schematic structural diagram of a BEB according to an embodiment of the present invention, where the BEB may execute the message processing method according to the foregoing embodiment, and this embodiment only briefly describes the structure of the BEB, and a specific working principle of the BEB may be combined with the method embodiment. As shown in fig. 8, the BEB may include: an information acquisition unit 81 and an information transmission unit 82; wherein,
