Problems solved by technology

[0003] The CPB module is a brand new module with special functions. Therefore, it needs a verification model and method that can be compatible with multiple ports, two modes and two directions at the same time. However, there is currently no verification model and method that can satisfy the CPB module test. method

Embodiment Construction

[0048] Embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0049] An embodiment of the present invention provides a multi-channel packet cache scheduling simulation verification method, including the following steps:

[0050] Branch line separation direction, according to the test mode selection, the data frames generated by each sequence generator are mapped from each service channel to a unified data channel, and the data frames are scheduled and processed by the ILK scheduler, or the data generated by each sequence generator is The frame is directly mapped to the scheduler corresponding to each service type for scheduling processing; the simulated data frame is received from the central packet buffer module to be tested according to the bus timing, and the data frame is descheduled and sent to the comparator module corresponding to each sequence generator to compare;

[0051]In the direction of bra...

Abstract

The invention discloses a packet cache scheduling simulation verification method and system supporting multiple channels, and relates to the technical field of communications. According to the invention, the mapping and de-mapping of data frames generated by each sequence generator on each service channel and a unified data channel can be realized; bus driving and receiving can adapt to various interface time sequence requirements, and each path and a service channel thereof can be well managed through the link controller, so that the verification requirements of multiple ports and two directions of the CPB can be completely compatible, and the universality and the flexibility are very good.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a multi-channel packet buffer scheduling simulation verification method and system. Background technique [0002] With the rapid development of mobile communications and Internet communications, operators are eager to realize 5G commercial use. At present, 5G-related technical research has entered the system demonstration stage, and 5G pilots have been launched in Beijing, Shanghai and other cities in China. The higher bandwidth and lower latency requirements of 5G have triggered the increase in core network transmission bandwidth. POTN equipment with powerful transmission capabilities and node scheduling capabilities is a converged solution to meet the large-capacity transmission requirements of mobile 5G application backbone networks. The CPB (Central packet buffer, central packet buffer) module is the core module of POTN equipment. It mainly completes unified and cent...
