Abstract

The invention relates to the technical field of communication, in particular to a multilevel message caching device and method for distributed communication equipment. Which comprises a TM chip and at least one group of PP chips and PIC chips, and is characterized in that the TM chip is connected with an exchange network, sends a service message to the PP chips, and controls the sending and pause of the service message according to a first flow control signal of the PP chips; the PP chip is the backward stage of the TM chip, and the PP chip processes the service message, controls the sending and pause of the flow according to the second flow control signal of the PIC chip, and sends the corresponding first flow control signal to the TM chip according to the own cache data volume; and the PIC chip is the post-stage of the PP chip, is connected with the physical port of the panel, processes the physical port of the panel, and sends a corresponding second flow control signal to the PP chip according to the own cache data volume, so that the flow lower than the rate of the panel port does not enter the cache. According to the invention, the requirement of a 5G bearer network on port cache time delay can be met, and the problem of cache bottleneck of a single chip is solved.

Description

Technical field

[0001] The present invention relates to the field of communication technologies, in particular to a device and method for multi-level message caching of distributed communication equipment.

Background technique

[0002] Large-scale video services such as short video, live TV, high-definition video on demand, and virtual reality (VR for short) are the main application scenarios in the early stage of 5G development. One of the key technologies of these video services is the large-scale reporting of 5G bearer network equipment. Only enough packet buffers can support smooth high-definition video playback. 6. When 5G networks carry large video services such as short videos, live TV, high-definition video on demand, VR, etc., according to the statistics of each operator, communication equipment is required. Only with the ability of port buffering 60ms packets can it meet the smooth playback of various high-definition videos.

Examples

Embodiment 1

[0042] In this embodiment, a plurality of chips with different functions are used to form a multi-level cache, and the multi-level flow control is triggered through the linkage among the multiple chips, so as to expand the packet cache capacity of the single board card.

[0043] like figure 1 As shown, it is a schematic diagram of the chip connection of the apparatus for multi-level message buffering of distributed communication equipment provided in this embodiment in a typical communication equipment service board card. In the device provided in this embodiment, each single board is connected by multi-level chips, including a TM chip 1 , and at least one group of PP chips 2 and PIC chips 3 . Each group of PP chips 2 and PIC chips 3 are serially connected and connected to an interface of the TM chip 1 to complete packet parsing and processing and physical interface sending and receiving. Each PP chip 2 and PIC chip 3 are connected in parallel to realize the processing and fo...

Embodiment 2

[0059] On the basis of the apparatus for multi-level message buffering of distributed communication equipment provided in the above-mentioned Embodiment 1, the present invention also provides a method for carrying out message buffering by the above-mentioned apparatus.

[0060] like Figure 4 As shown, the specific steps of the method for multi-level packet buffering of a distributed communication device provided by the embodiment of the present invention are as follows:

[0061] Step 101: Use the TM chip in the apparatus for multi-level message buffering of the distributed communication equipment provided in Embodiment 1 to connect to the switching network.

[0062] Using the apparatus provided in Embodiment 1, multi-level chip connection is implemented on the service board of the distributed equipment. like Figure 5 Shown: The TM chip is connected to the switching network, which is used for traffic management of the entire service board. The PP chip is used in the front-...
