Device and method for realizing dynamic multiplexing transmission of TDM and packet services

Abstract

The invention discloses a device and method for realizing dynamic multiplexing transmission of TDM and packet services, and relates to the technical field of optical network communication. A main control module of the device generates various control signals according to user configuration information; a dynamic channel resource switching module performs configuration and scheduling switching of channel resources according to the generated control signals, so that channel connection between a multiplexing data transmission module and a TDM cache or packet cache is established; a receiving module processes client side data according to the generated control signals; a segmentation data cache module stores the processed data in the corresponding TDM cache or packet cache; and the multiplexing data transmission module obtains data from the TDM cache or packet cache by utilizing the current channel connection according to the control signals, and forwards the data to the system side. On the premise that channel port resources are not increased, dynamic multiplexing transmission of the TDM and packet services is realized; redundancy of the channel port resources is avoided; and the utilization rate of the channel port resources is increased.

Description

technical field [0001] The invention relates to the technical field of optical network communication, and specifically relates to a device and a method for realizing dynamic multiplexing and transmission of TDM (Time Division Multiplexing, time division multiplexing) and packet services. Background technique [0002] Regardless of the long-distance transmission of services or the rapid growth of IP (Internet Protocol, Internet Protocol) services in the future, it is very necessary to adopt the joint networking mode of TDM services + packet services. Considering the many advantages of the joint networking mode, it is recommended to use the joint networking mode for the construction of the metropolitan local network except in areas where there is no TDM service or the TDM service cannot cover the backbone core points in a short period of time. The TDM service + packet service joint networking mode, with its powerful IP service access, aggregation and flexible scheduling capabi...

Problems solved by technology

[0003] In the prior art crossover equipment, although the joint networking mode of the TDM system + packet system has been used to achieve normalized transmission on the same board and a single disk, the technical solution uses two sets of channel and port resources to be separated method of transmission

For example, when a 100G board needs to achieve a maximum of 100G TDM and a maximum of 100G packet services, the technical implementation plan requires a 200G port resource channel system for separate transmission, 100G channel resources are used for TDM transmission channels, and 100G is used for packet service transmission , such a technical implementation scheme greatly wastes channel port resources, and a 100G board needs to be configured with a 200G port resource system module

However, in actual use, the 100G TDM transmission channel or the 100G packet service transmission channel will not be used at full capacity. Therefore, there is a large resource redundancy, resulting in a low utilization rate of the port channel resource module of a single board. The cost of a single line card is also relatively high, which cannot meet the access requirements of new equipment forms where TDM and packet mixed services coexist
