Time slot assignment method and network communication device

Abstract

The embodiment of the invention relates to a technical field of network communication and in particular discloses a method for distributing time slots. The invention includes the following processes:when a node receives a request message of time slot distribution of a service and searches for the usable time slots according to the request message; a 4n time slot unit grouping is taken as the searching object and every time slot is browsed in the 4n time slot unit grouping; if a usable time slot is found out, the usable time slot is distributed to the corresponding service of the request message; if the n is a integer greater than zero, capacity of the 4n time slot unit grouping is not less than the time slot capacity needed by the service. The embodiment of the invention also discloses anetwork communication device used for realizing the time slot distribution. By using the proposal of the invention, the reasonable distribution to the time slot can be realized; the generation of fragment time slots can be effectively reduces; the arrangement work for the time slot in the late stage can be avoided, thus reducing usage rate of additional spending of the system due to the arrangement of the fragment time slots.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a time slot allocation method; the invention also relates to a network communication device for realizing time slot allocation. Background technique [0002] With the rapid development of network interconnection technology and communication requirements, Automatically Switched Optical Network (ASON) technology has emerged. ASON is a new generation of intelligent optical network that completes automatic switching functions under routing and signaling control. It can also be regarded as an optical transport network with standardized intelligence. Intelligent optical network is an optical fiber communication technology that emerged in the last century and has only been widely used by operators in this century. Compared with traditional SDH networks, intelligent optical networks can make full use of existing network resources and provide more efficient network manageme...

Problems solved by technology

Therefore, for standard concatenation services that require a larger value, for example, 64 standard concatenation services, 64 consecutive time slots must be allocated accordingly, if the link bandwidth is sufficient, but "enough" at this time usually means that there are many fragmented There are less than 64 consecutive time slots, which affects the normal allocation of time slot resources for concatenated services

[0006] Obviously, this technical solution is an after-the-fact remedy method, and its essence cannot avoid the generation of fragmented time slots. The disadvantage is that the network management needs to frequently organize the fragmented time slots, and also optimize and adjust the original services , not only takes up a lot of system resources, but also the entire implementation operation is very complicated and inconvenient. In addition, this technical solution will also face some limiting factors, such as link or node failure during defragmentation, which may affect business.
