Abstract

The embodiment of the invention discloses a method and a device for crossing time slots. The method comprises the following steps of: receiving a transmission convergence layer (TC) frame and extracting at least one time slot unit from payload of the TC frame, wherein each time slot unit has different units; performing crossed scheduling on the extracted time slot unit according to the preset time slot table; and outputting a crossed TC frame according to the preset generating frame header information and the crossed scheduling result, wherein a bandwidth map in the crossed TC frame at least comprises an initial position and an end position of the time slot unit, and the payload of the crossed TC frame comprises the time slot unit. The embodiment of the invention also provides an exchangedevice. In the technical scheme provided by the embodiment of the invention, the time slot units in the crossed TC frame do not need to supplement idle data to ensure that each time slot unit has thesame unit, so that the waste of bandwidth resource is reduced.

Description

technical field

[0001] The present invention relates to the field of communication technology, in particular to a time slot crossover method and crossover device. Background technique

[0002] Existing networks carry various services, such as voice, video, online games, and web browsing. The time slot crossover technology plays an important role in supporting the transmission of various service data in the network. By adopting the time slot crossover technology, the equipment centralizes the service data, classifies the service data, and sends the service data to the target address, so that each The transmission path of such business data in the network is more reasonable.

[0003] The current MAN network includes: Synchronous Digital Hierarchy (SDH, Synchronous Digital Hierarchy), Multi-service Transport Platform (MSTP, multi-service transport platform), Packet Transmission Network (PTN, Package Transmission Net), Layer 2 Ethernet, etc. form. Therefore, multiple transmis...
