Detailed Description

In this embodiment, key terms are defined as follows:

Abbreviations	English full name	Chinese interpretation
			SRv6	Segment Routing IPv6	IPv6 source routing
SID	Segment Id	Segment identifier
			Node-SID	Node Segment ID	Device segment identifier
VPN-SID	Virtual Private Network Segment ID	Virtual private network segment identifier

Nowadays, SRv's 6 traffic is divided into two main classes SRv BE and SRv TE. Referring to fig. 1, when the be service is decapsulated, only one SID, i.e., IPv6Da, needs to be processed. Referring to fig. 2, te traffic needs to process two SIDs, node-SID (IPv 6 Da) and VPN-SID (last SID in SRH), respectively, when decapsulating.

It is found that the current device only supports processing one SID in one pipeline, and for a scene needing to process two SIDs, the decapsulation process can be completed by executing the pipeline twice in a loop-back mode. As shown in FIG. 1, the node for decapsulation is PE2, and for SRv-BE service, PE2 only needs to process IPDA (D1:100), and the decapsulation process is performed. For SRv6-TE traffic, PE2 needs to handle IPDA (D1: 40) and SID [0] (D1: 100).

It is known that the existing network chip pipeline only supports SRv SIDs once, and for SRv-TE traffic, more complex processing operations need to be performed. Referring to fig. 2, the method includes: the first pass pipeline matches IPDA, performs a SWAP operation, copies SID [0] to the IPDA location, loops back to the reentry pipeline. The second pass pipeline matches IPDA, which is now SID [0], performs the DECAP (decapsulation) operation, and completes the business process.

Under the condition that SRv-TE service needs to carry out loopback processing, in view of the fact that the loopback bandwidth of a network chip is limited, the bandwidth of the network chip is generally only 1/4 or less of the whole bandwidth of the network chip, and therefore when the loopback bandwidth is insufficient, packet loss occurs and the service is affected. Even if the loop-back bandwidth of the network chip is upgraded, for example, 1/2 of the overall bandwidth of the network chip is taken as the loop-back bandwidth, the bandwidth providing capability of the network chip is affected, and the available bandwidth which is finally provided may be only 1/2.

Based on the above-mentioned research, the embodiment of the present invention provides an information processing scheme, compared with the prior art for SRv-TE traffic, the first pass uses IPDA to search, performs a SWAP (SWAP) operation, SWAPs the last SID (SID [0 ]) in the extension header to the IPDA position, and then loops back, and when the second pass pipeline processes, the IPDA is processed as the first pass process. In the embodiment, the processing logic of SRv-TE service messages is skillfully improved, and the SRv-TE service messages are processed in one assembly line without carrying out loop-back processing as in the prior art, so that the processing convenience of SRv-TE service messages is improved, the bandwidth of a network chip is saved, the available service bandwidth of the network chip is further increased, packet loss caused by insufficient loop-back bandwidth is avoided, and the message processing reliability is improved.

Fig. 3 is a block diagram of an electronic device 100 according to the present embodiment, where the electronic device 100 in the present embodiment may be a server, a processing device, a processing platform, etc. capable of performing data interaction and processing. The electronic device 100 includes a memory 110, a processor 120, and a communication module 130. The memory 110, the processor 120, and the communication module 130 are electrically connected directly or indirectly to each other to realize data transmission or interaction. For example, the components may be electrically connected to each other via one or more communication buses or signal lines.

Wherein the memory 110 is used for storing programs or data. The memory 110 may be, but is not limited to, random access memory (Random Access Memory, RAM), read Only Memory (ROM), programmable read only memory (Programmable Read-only memory, PROM), erasable read only memory (Erasable Programmable Read-only memory, EPROM), electrically erasable read only memory (Electric Erasable Programmable Read-only memory, EEPROM), etc.

The processor 120 is used to read/write data or programs stored in the memory 110 and perform corresponding functions.

The communication module 130 is configured to establish a communication connection between the electronic device 100 and other communication terminals through the network, and is configured to transmit and receive data through the network.

It should be understood that the structure shown in fig. 3 is merely a schematic diagram of the structure of the electronic device 100, and that the electronic device 100 may further include more or fewer components than those shown in fig. 3, or have a different configuration than that shown in fig. 3. The components shown in fig. 3 may be implemented in hardware, software, or a combination thereof. For example, a network chip for SRv traffic handling may be included in the electronic device 100.

Referring to fig. 4 in combination, a flowchart of an information processing method according to an embodiment of the invention may be executed by the electronic device 100 shown in fig. 3, for example, may be executed by the processor 120 in the electronic device 100. The information processing method includes S110, S120, S130, and S140.

S110, obtaining SRv-TE service messages to be processed.

S120, analyzing the SRv-TE service message to obtain the Internet protocol destination address and the segment identifier of the segment routing message header of the SRv-TE service message.

S130, searching and obtaining the searching state corresponding to the SRv-TE service message based on the Internet protocol destination address and the segment identifier.

And S140, determining processing logic corresponding to the SRv-TE service message according to each searching state.

By skillfully setting processing logic, SRv-TE service messages are processed in one-pass assembly line without loop-back processing, so that the bandwidth of a network chip is saved, the available service bandwidth is improved, and the convenience and reliability of SRv-TE service message processing are improved.

In S120, the section identifier of the section routing header and the internet protocol destination address obtained by parsing SRv-TE service packets can be flexibly implemented.

For example, the SRv-TE service packet may be directly parsed to obtain an ip destination address of the SRv-TE service packet, which is identified as IPDA.

For another example, when the value of NextHeader field of the Header is the first set value, the Routing Type may be extracted from the Routing Header. The first setting value is used for representing that the SRv-TE service message carries a Routing Header. And under the condition that the Routing Type is a second set value, extracting SID [0] from the SRH, and taking the SID [0] of the SRH as a segment identifier of the segment Routing message header. Wherein the second set point is used for characterizing the SRH format.

For example, referring to fig. 5, in the case that the format of SRv-TE service packet is shown in the structure table in fig. 5, the main contents in the structure are defined as follows:

Internet protocol (Internet Protocol, IP), destination address (Destination Address, DA), internet protocol destination address (Internet Protocol Destination Address, IPDA), internet protocol version six (Internet Protocol Version, IPv 6), internet protocol version six destination address (IPv 6 DA).

The IPv6Valid represents that the message is in IPv6 format, and is identified by the ETHERTYPE =x0806 field of the ethernet message.

NextHeader is a field of the IPv6 header, which is used to indicate the type of the following content of the IPv6 header, taking the first setting value as 43 as an example, and when NextHeader is 43, it indicates that the following content of the IPv6 header is an SRH extension header (Segment Routing Header).

Based on the above definition, as the flow shown in fig. 5, the message parsing flow is as follows:

For SRv6-TE traffic packets, since the first 12 bytes of the ethernet packet are ethernet addresses, the next 2 bytes are ETHERTYPE, when ETHERTYPE =0x0806, IPv6 valid=1.

The Next Protocol is fetched from the 7 th Byte of the IPv6 Header, and if 43, the Routing Header is carried, and then the Routing Type is fetched from the 3 rd Byte of the Routing Header. If 4, representing the SRH format, srhValid =1, and SID [0] is taken from the 9 th Byte of the SRH.

IPv6DA is taken from the 9 th byte of the IPv6 header and SL (Segment Left) is taken from the 4 th byte of the SRH.

In the case that SRv-TE service packets are obtained by parsing, S130 may be implemented as follows: and searching whether the SRv-TE service message corresponds to a first searching result or not based on the IPDA.

For example, based on IPDA, searching the IPv6Valid of the SRv-TE service message, and under the condition that the IPv6Valid is found, analyzing to obtain the IPv6Da.

And putting the IPv6Da into a Hash0Key to perform Hash searching. If the hash result is found, the hash0Cmd is taken out from the hash result, SWAP operation is configured on the hash0Cmd to replace IPv6Da, and hit0 is set to be 1. If the hash result is not found, setting hit0 to 0; wherein, when hit0 is 1, it indicates that there is a first search result, and when hit0 is 0, it indicates that there is no first search result.

For example, srhValid of the SRv-TE service packet is looked up based on SID [0] of the SRH.

And under the condition that SrhValid is found and the SL is obtained through analysis as a third set value, putting SID [0] into a Hash1Key for Hash searching. If the hash result is found, the hash1Cmd is taken out from the hash result, the unpacking operation is configured in the hash1Cmd, the IPv6 and the SRH are deleted, and the hit1 is set to be 1. If the hash result is not found, set hit1 to 0. Wherein, when hit1 is 1, it indicates that there is a second search result, and when hit1 is 0, it indicates that there is no second search result.

For example, referring to fig. 6, after the message parsing is completed as shown in fig. 5, if IPv6Valid is found, the IPv6Da obtained by the parsing is put into the Hash0Key, a standard Hash lookup is performed, if there is a result in the Hash lookup, hit0 is set to 1, and the Hash0Cmd is taken out from the Hash lookup result, and the typical SWAP operation configured by the Hash0Cmd replaces the IPv6Da.

If SrhValid is found and the parsed SL is 1, the parsed SID [0] is put into a Hash1Key, standard Hash lookup is executed, if the Hash lookup has a result, hit1 is set to 1, the Hash1Cmd is taken out from the Hash lookup result, the general decapsulation operation of the Hash1Cma configuration is carried out, and both IPv6 and SRH are deleted from the message.

In this embodiment, the searching based on the internet protocol destination address and the segment identifier may be performed in parallel, so as to obtain the searching states corresponding to SRv-TE service packets respectively. Illustratively, for SRv-TE service messages, the last SID (SID [0 ]) in the IPDA and message extension header is parsed, and the searching and processing are performed in parallel. On the basis of completing SRv-TE service message processing by one-pass assembly line, the processing efficiency is further improved.

In the case that the search status is whether the first search result and the second search result are corresponding, S140 may be implemented by: and under the condition that the first search result and the second search result exist, the first search result represents that the SRv-TE service message needs to be processed locally, and the second search result represents that the SRv-TE service message needs to be unpackaged, the SRv-TE service message is determined to be unpackaged locally.

And under the condition that the first search result exists and the second search result does not exist, determining to exchange the SRv-TE service message locally.

For example, referring to fig. 7, after obtaining the states of Hit0 and Hit1 based on the flow shown in fig. 6, subsequent processing logic is determined according to the states of Hit0 and Hit 1:

If Hit0 has no lookup result, then no processing is needed, skipping the logic of SRv.

If Hit0 has a search result, but Hit1 has no search result, the operation of hash0 is executed at this time, and standard IPv6Da exchange operation is performed.

If Hit0 has a search result and Hit1 also has a search result, which means that the message needs to be terminated, standard decapsulation operation is performed, and the IPv6 header and SRH header information is deleted.

Thus, the SRv-TE service message is conveniently and reliably processed in one-pass pipeline.

In order to more clearly illustrate the implementation principle of the present embodiment, please refer to fig. 8 in combination, and take the implementation of each function of the information processing method based on the parsing module, the searching module and the processing module as an example, the scheme of processing two SIDs based on a pipeline in the present embodiment is illustrated.

in fig. 8, the parsing module is configured to parse the message to obtain SID [0] of the IPDA and the SRH, and corresponding IPv6Valid, srhValid and SL.

The searching module is used for supporting two parallel searching, and adding one parallel searching to search SID [0] on the basis of supporting the original one-time searching and fixing the use of IPDA, and checking whether SL is 1 before searching SID [0] and possibly performing decapsulation (Decap) when SL is 1 in order to avoid the situation of mismatching.

The processing module is used for merging (merge) results according to the two searching states to determine message processing logic. The processing module performs mainly two operations, one is switching (Swap) and the other is decapsulating (Decap). Based on the search states corresponding to IPDA and SID [0], three processing states exist for the message:

First, the message is terminated and the packet is Decap (hit1=1 and hit0=1 in fig. 7).

Second, the next SID is copied to IPDA by Swap to continue processing for subsequent devices (hit1=0 and hit0=1 in fig. 7).

Third, the message that needs no processing is filtered, the SRv processing is skipped, and normal routing processing is performed (hit1=0 and hit0=0 in fig. 7).

Taking fig. 2 as an example, in the case where the IPv6DA of the message received by the device is D1::40, the SID [0] in the SRH is D1::: 100, and sl=1 in the SRH, since the message is in IPv6 format and carries the SRH, two searches are performed, the IPv6DA is used for the first time (D1: 40), and the SID [0] is used for the second time (D1: 100). When the device is not D1:40, the first search will not result, and therefore will not process SRv. When the device is D1:40, but D1:100 is not the device configuration, the first lookup will have the result, performing standard SWAP operations. When the device is D1:40 and D1:100 is the device configuration, both the first and second lookups will have results and SL=1, thus standard decapsulation operations will be performed.

By using the information processing scheme in the embodiment of the invention, the service message of SRv-TE only needs to be executed once in the unpacking equipment, and twice in the unpacking equipment is not needed, so that the processing capacity is improved by about one time. The new search interface and the processing logic are completely parallel to the original pipeline search interface and the processing logic, so that the length of the pipeline is not increased, the forwarding delay is kept, and the hardware cost is not increased. The newly added searching interface decides whether to search according to the characteristics of the message, so that invalid searching and abnormal conditions caused by invalid searching are avoided, and the power consumption of the chip is reduced.

In order to perform the respective steps of the above-described embodiments and the respective possible ways, an implementation of an information processing apparatus is given below. Referring to fig. 9, fig. 9 is a functional block diagram of an information processing apparatus 140 according to an embodiment of the present invention, where the information processing apparatus 140 can be applied to the electronic device 100 shown in fig. 3.

The information obtaining module 141 is configured to obtain SRv-TE service packets to be processed.

The information processing module 142 is configured to parse the SRv-TE service packet to obtain an internet protocol destination address and a segment identifier of a segment routing header of the SRv-TE service packet; searching and obtaining the searching state corresponding to the SRv-TE service message based on the Internet protocol destination address and the segment identifier respectively; and determining processing logic corresponding to the SRv-TE service message according to each searching state.

On the basis of the above, the embodiment of the invention also provides a computer readable storage medium, which comprises a computer program, and when the computer program runs, the electronic equipment where the computer readable storage medium is located is controlled to execute the information processing method.

Compared with the prior art that the processing flow needs to be looped back and executed twice for SRv-TE service, the scheme in the embodiment of the invention is inconvenient to realize, and packet loss possibly occurs due to insufficient bandwidth of the looped back. In the embodiment, the processing logic of SRv-TE service messages is skillfully improved, and the SRv-TE service messages are processed in one assembly line without carrying out loop-back processing as in the prior art, so that the processing convenience of SRv-TE service messages is improved, the bandwidth of a network chip is saved, the available service bandwidth of the network chip is further increased, and the message processing reliability is improved.
