A system and method for uniform scanning of logical links

Abstract

The invention discloses a logical link uniform scanning system. The system includes: a storage module, which is used to establish the corresponding relationship between each physical port number and the logical link number in a logical link table, and establish the corresponding relationship between each physical port number. The starting address, and the storage address of each logical link number; the calculation module is used to set the total number of scan rounds required to scan all the logical links in the logical link table, and according to the total number of scan rounds and The total number of logical links corresponding to each physical port number calculates the number of logical links to be scanned corresponding to each physical port number in the current round; the acquisition module is used to obtain each logical link to be scanned The storage address of the link in the logical link table, and read all corresponding logical link numbers to be scanned in the logical table. Through the present invention, uniform scanning of logical links of each physical port is realized.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a system and method for evenly scanning logical links. Background technique [0002] Operation Administration and Maintenance (OAM) messages mainly complete daily network and business analysis, prediction, planning, and configuration work, perform daily operations on network and business testing, and fault management, and detect network traffic through regular queries. Faults, various maintenance and alarms are generated, the fault information is transmitted to the management entity, and the normal operation of the network is guaranteed by scheduling or switching to other entities. Programmable gate arrays can be used in network equipment to be responsible for sending and receiving fast OAM messages. [0003] The communication network equipment is equipped with multiple logical links, such as 16K logical links, which are used to send business data most of the time, but in...

Problems solved by technology

Therefore, if the 16K logical links are scanned in order to obtain the corresponding physical ports, and the OAM message sending request is sent out from the physical port, the physical port will send messages unevenly.

For example, when scanning logical links, among the 16K logical links, the physical port corresponding to the 0-2K logical link is 0, and the corresponding physical port to the 2K-4K logical link is 1. At this time, the port 0 will receive requests to send OAM packets continuously in a short period of time, while physical port 0 is idle in the rest of the time, and port 1 is the opposite, so physical ports will send OAM packets unevenly. , and will cause too many requests for sending packets on a certain physical port, causing congestion and even packet loss

For another example, among the 16K logical links, only 0-4K logical links have OAM packet sending requests, and the sending requests of 0-4K logical links are evenly distributed on multiple ports. Within a period of 1 logical link, the packet sending request of the physical port is uniform, but when scanning the following 12K logical links, all the physical ports are in the idle state, which also causes the physical port to send the packet.

[0004] Therefore, the present invention proposes a technical solution for uniform scanning of logical links, which solves the problem of uneven message sending requests of physical ports in the prior art
