Method and device for processing routing of time division multiplexing service

Abstract

The invention discloses a method and device for processing intelligent routing of a time division multiplexing service. The method comprises the steps of: selecting a work mode and a transmission interface for a time division multiplexing device and determining a transmission direction of to-be-carried services on the time division multiplexing device and a total bandwidth of the transmission direction according to the selected work mode and the selected transmission interface; distributing the to-be-carried services to the transmission interface according to the type of the transmission interface, determining the specific positions of the services in a channel, and sequencing as well as numbering the services; establishing connection relationships between local services and the to-be-carried services distributed on the transmission interface so as to finish routing distribution of the local services. For the realization of the technical scheme of the invention, the method and device for processing intelligent routing of the time division multiplexing service, disclosed by the invention, have the advantages of simple configuration of a routing mechanism and routing rules, easy implementation and wide application range, and are suitable for transmission channels with different rates and different non-standard transmission channels. According to the technical scheme of the method and device for processing intelligent routing of the time division multiplexing service, disclosed by the invention, complex bottom layer operation is avoided, exchange operation of the service routing and maintenance difficulty of the device in a later period are simplified, and usability of the device is improved.

Description

technical field [0001] The present invention relates to the technical field of network communication, and more specifically, relates to a method and device for processing time division multiplexing (English full name is Time Division Multiplex, hereinafter referred to as TDM) service routing. Background technique [0002] In the current narrowband multi-service multiplexing equipment based on TDM technology, the transmission interface is E1 interface, of which the E1 interface is the European E1 standard (2.048Mbit / s). The bandwidth of each time slot is 64Kbit / s, and the length of the time slot is 8bit. The equipment multiplexes various services to be processed into each time slot of the framed E1 for transmission, and the minimum unit for processing services is 64Kbit / s. [0003] When maintenance personnel perform routing and switching on various services, they regard various services and transmission channels as some E1 channels with a granularity of time slot (64kbit), th...

Problems solved by technology

[0004] For some special application scenarios, such as: compressed voice services (bandwidth less than 64Kbit / s), data services that are not integer multiples of 64Kbit / s (Ethernet, UART, etc.), transmission channel bandwidth less than 2.048Mbit / s (not Standard private frame structure), etc., these special requirements will lead to the unfixed bandwidth of the transmission channel, and the granularity of business processing is not fixed. If the above method is still used for routing management, it is necessary to design a variety of different routing tables and algorithms, corresponding to different The transmission rate and business processing granularity are very high, and the design and implementation are very complex. In addition, the complex underlying business processing process in units of bits is exposed to the maintenance personnel. This configuration method also brings great difficulties to the later maintenance and use. Great difficulty, requiring maintenance personnel to be very familiar with relevant business features, including some non-standardized services and transmission channels, which brings great difficulty to maintenance personnel
