Technical Field

UDP (User Datagram Protocol) is a connectionless-oriented transport layer Protocol that provides transaction-oriented simple unreliable messaging services.
For a TCP/UDP session, the sending and receiving are reciprocal. That is, a and B communicate with each other, a may be sent to B, and B may also be sent to a, in this process, a sends to B or B sends to a packet including 4 delivery parameters, IpSa, IpDa, L4Srcport, and L4DstPort, where IpSa and IpDa represent a pair of source address and destination address, and L4Srcport and L4DstPort represent a pair of source port and destination port; in the prior art, in the process that a sends a session to B and B sends a session to a, two parameters are exchanged with one another in pairs, so that when TCP/UDP sessions are matched by using flow tables such as ACL and IPFIX, two entries, namely two configurations, are needed, and two flow table resources need to be occupied.

Detailed Description
The present invention will be described in detail below with reference to specific embodiments shown in the drawings. These embodiments are not intended to limit the present invention, and structural, methodological, or functional changes made by those skilled in the art according to these embodiments are included in the scope of the present invention.
In practical application, only one TCP/UDP session is generally concerned, and whether the session is sent to B by A or sent to A by B is not concerned, meanwhile, only one Entry is needed for matching the TCP/UDP session by using a flow table, and based on the situation, the chip implementation method for TCP/UDP session identification is disclosed in the patent, and only one flow table is used for identifying the TCP/UDP session.
As shown in fig. 1, a method for implementing TCP/UDP session identification based on a chip according to an embodiment of the present invention includes:
s1, when receiving the session packet of TCP/UDP, parsing the session packet to obtain two sets of transfer parameters, where one set of transfer parameters includes: ipsa and IpDa, wherein another set of delivery parameters includes L4Srcport and L4 DstPort;
sequencing the two groups of transmission parameters respectively according to the sequence of data from big to small or from small to big;
s2, after the sorting is finished, writing the two sorted groups of transmission parameters into the same flow table resource of the memory in sequence;
and S3, when receiving the next group of TCP/UDP session packets, circularly executing the step S1, judging whether the two groups of transmission parameters after finishing the sorting are the same as the transmission parameters stored in the flow table resources, if so, directly calling the flow table resources, and if not, executing the step S2.
In the specific embodiment of the present invention, in step S1, when the switch receives the message, the message is analyzed to obtain two sets of parameters, where one set of transmission parameters includes: IpSa and IpDa, wherein another set of delivery parameters includes L4Srcport and L4 DstPort. And the two groups of parameters are written into the same flow table resource of the memory.
In practical application, the flow table resources mainly include an ACL memory corresponding to the ACL engine and an IPFIX memory corresponding to the IPFIX engine.
In the specific implementation mode of the invention, two groups of parameters are respectively sorted according to the data size, and the parameters are written into the corresponding flow table resources after being sorted, so that only one flow table resource is occupied in the process of data exchange between the same two devices corresponding to the same service, and the data interaction can be realized.
ACL is an abbreviation of Access Control List, Chinese transliteration: an access control list; IPFIX Engine translates to IPFIX Engine, ACL Engine translates to ACL Engine.
In the first preferred embodiment of the present invention, the step S2 specifically includes: after the sorting is completed, the two sorted groups of transmission parameters are written into the same flow table resource of the ACL memory in sequence.
In a second preferred embodiment of the present invention, the step S2 specifically includes: and after the sequencing is finished, writing the two groups of sequenced transmission parameters into the same flow table resource of the IPFIX memory in sequence.
In a third preferred embodiment of the present invention, the step S2 specifically includes: after the sequencing is finished, synchronously or asynchronously writing the two groups of sequenced transmission parameters into the same flow table resource of the IPFIX memory and the same flow table resource of the ACL memory in sequence.
In a specific application of the present invention, it is only ensured that one of the flow table resources corresponding to the two sets of parameters is written and called in an ordering manner, corresponding to a plurality of flow table resources in the switch. Therefore, flow table resources can be saved, and the performance of the device can be improved.
In a preferred embodiment of the present invention, after obtaining the two sets of transmission parameters, the method further includes determining whether the TcpBidiFlowSessionEn signal corresponding to each set of transmission parameters is enabled, and if so, sorting the two sets of transmission parameters according to the sequence of data from large to small or from small to large.
If not, after the TcpBidiFlowSessioneN signal is enabled, the two groups of transmission parameters are sorted according to the sequence of data from large to small or from small to large respectively.
TcpBidiFlowSessionEn is a standard response signal in a switch. In this penalty hit, when it is enabled, the delivery parameters are ordered. When the corresponding service is applied specifically, the transmission parameter sequencing is controlled through the response signal, so that the resources are saved.
Referring to fig. 2, a specific example of a third embodiment is applied to the present invention, in this example, after TCP/UDP pkt enters a switch, the pkt is analyzed to obtain IpSa and IpDa, and L4Srcport and L4 DstPort; when response signals TcpBidiFlowSessioneN of an ACL Engine and an IPFIX Engine are enabled respectively, sequencing two groups of transmission parameters according to the data size respectively; when the response signal TcpBidiFlowSessionEn is not enabled, no sorting process is performed. For example, four positions of IpAddress1, IpAddress2, L4Port1, and L4Port2 are filled in order in the same flow table. Setting the larger data of IpSA and IpDa in each group of transmission parameters, putting the larger data into IpAddress1, and putting the smaller data of IpSa and IpDa into IpAddress 2; the larger of the L4Srcport and L4DstPort data is placed into the L4Port1, and the smaller of the L4Srcport and L4DstPort data is placed into the L4Port 2. And then, the ACL Engine is issued to an ACL memory through CPU software, namely, the software mode is issued. The IPFIX Engine is directly inserted into the IPFIX memory by the chip, namely, the IPFIX Engine is issued in a hardware mode. Thus, an Entry is matched with the TCP/UDP session.
It should be noted that, in the example shown in fig. 2, in the process of implementing recognition of TCP/UDP session by ACL Engine and IPFIX Engine, the processing of IpDa, IpSa, L4DstPort, and L4Srcport by ACL Engine and IPFIX Engine is the same. In other embodiments of the present invention, one of the ACL Engine and the IPFIX Engine may be selected to be sequenced, and the other one may be subjected to session processing in a conventional manner, which is not described herein again.
