Description

Technical Field

[0001] The present invention relates to the technical field of network communication, and in particular to a load balancing output system for implementing network traffic differential replication based on Barefoot. Background Art

[0002] With the rapid development of network technology, the network has penetrated into thousands of households, bringing more and more convenience to people's work and life. Therefore, the application scenarios are also increasing and becoming more and more complex, and users have higher and higher requirements for network traffic processing capabilities. In the multi-user control scenario, users have put forward more and more customized output requirements for the message copying and output of communication products. Traditional switching chips cannot modify the content of the copied messages again while processing user traffic replication, which seriously affects the user's work efficiency and results. Therefore, the existing implementation scheme can no longer meet the needs of most customers, and a smarter and faster message copy output processing method is urgently needed. To solve this problem, how to achieve differentiated output required by different users after copying a message is a difficult point. Summary of the invention

[0003] To solve the above problems, this patent proposes a system for implementing differentiated replication and load balancing output of network traffic based on Barefoot. According to the ACL rules configured by different users, the identification, extraction and matching of network traffic are realized, and one flow input and multiple flows are differentiated and replicated for the traffic matching the ACL, with a maximum of 8 different flows, each of which is output from a load balancing port selected in a different port aggregation group; the characteristic field at a specific position of the message entering Barefoot is extracted, and the number of copies of the message is identified in the characteristic field. If multiple copies are required, the message is transferred to the TM module, and after the TM module replicates multiple copies of the message, it is handed over to the Egress module to parse and reassemble the replicated message, thereby modifying the replicated message and outputting it in a load balancing manner.

[0004] The specific steps are as follows: Step 1: A load balancing output system for network traffic differentiation replication based on Barefoot includes ACL management module, ACL matching module, user management module and Barefoot processing module. The functional modules are divided as follows: Figure 3 As shown, the ACL management module implements the management of adding, deleting and checking ACL rules, the ACL matching module implements the table lookup and matching of ACL rules to network traffic, the user management module implements the management of adding, deleting and checking users, and the Barefoot processing module implements the differential replication and port aggregation group load balancing output functions.

[0005] Step 2: The ACL management module and user management module complete the ACL rule configuration for different users. The ACL matching module realizes the identification, extraction and matching of network traffic, and marks the traffic matching the ACL rules with a feature field at a specific position. The feature field identifies the number of copies of the message.

[0006] Step 3: The feature field at a specific position of the message entering Barefoot is extracted. The feature field identifies the number of copies of the message. If multiple copies are required, the message is transferred to the TM module. After the TM module copies multiple copies of the message, it is handed over to the Egress module for parsing and reassembly of the copied message, thereby modifying the copied message and outputting it in a load-balanced manner.

[0007] Compared with the prior art, the technical solution of the present invention has the following significant beneficial effects: 1. According to customer needs, you can choose multiple copies and output the copied messages in a diversified way, which is convenient and fast.

[0008] 2. Realize load balancing output of port aggregation group to improve performance.

[0009] 3. Facilitate subsequent function iteration. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] In order to make the purpose and technical solution of the present disclosure more clearly understood, the present disclosure is further elaborated in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0014] Combination Figure 1Overall flow chart and Figure 2 Barefoot replication principle diagram, first parse and extract the message of the access device, then match the extracted message content with the ACL rules, and mark the message that matches multiple users with a specific tag and hand it over to Barefoot for processing. Barefoot extracts the characteristic field at a specific position of the received message, and the characteristic field identifies the number of copies of the message. If multiple copies are required, the message is transferred to the TM module. After the TM module copies multiple copies of the message, it is handed over to the Egress module to parse and reassemble the copied message, thereby realizing the modification of the copied message and load balancing output.

[0015] This solution effectively solves the problem of achieving differentiated load balancing output according to the needs of different users after copying a message, and can customize the message content required by different users.

[0016] The specific steps are as follows: Step 1: A load balancing output system for network traffic differentiation replication based on Barefoot includes ACL management module, ACL matching module, user management module and Barefoot processing module. The functional modules are divided as follows: Figure 3 As shown, the ACL management module implements the management of adding, deleting and checking ACL rules, the ACL matching module implements the table lookup and matching of ACL rules to network traffic, the user management module implements the management of adding, deleting and checking users, and the Barefoot processing module implements the differential replication and port aggregation group load balancing output functions.

[0017] Step 2: The ACL management module and user management module complete the ACL rule configuration for different users. The ACL matching module realizes the identification, extraction and matching of network traffic, and marks the traffic matching the ACL rules with a feature field at a specific position. The feature field identifies the number of copies of the message.

[0018] Step 3: The feature field at a specific position of the message entering Barefoot is extracted. The feature field identifies the number of copies of the message. If multiple copies are required, the message is transferred to the TM module. After the TM module copies multiple copies of the message, it is handed over to the Egress module for parsing and reassembly of the copied message, thereby modifying the copied message and outputting it in a load-balanced manner.
