Problems solved by technology

In the process of ODU multiplexing, the network management system needs to manually configure the time slot port number (Tributary Port Number, TPN) for two adjacent nodes, so that the optical network can be established between the two adjacent nodes according to the allocated TPN. For Optical Channel Transport Unit (OTU) links, since each link is manually configured with TPN, the workload of configuring TPN is huge and the error rate is high

Embodiment Construction

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0038] figure 1 A schematic diagram of an OTU link applicable to the embodiment of the present invention, such as figure 1As shown, when it is necessary to establish a service path of an ODU service, when the ODU service passes through the OTU link between the first node and the neighbor node serving as the first node, specifically, when it is necessary to establish a service path between the service source node and the service sink node When establishing a s...

Abstract

The embodiment of the invention relates to a method, a device and a system for allocating a time slot port number. The method comprises the steps of: receiving a service route requesting message having service classification sent by an adjacent node, confirming an OTU link carrying the ODU service according to the service route requesting message, confirming and leaving a leisure time slot sourcefor carrying the ODU service in the OTU link according to the service classification in the service route requesting message, allocating a time slot port number to the leisure time slot source, and sending a service route confirming message to the adjacent node. The method, the device and the system for allocating a time slot port number of the invention realize automatically acquiring the time slot port number, increase the allocating efficiency of the time slot port number because the operation of manually allocating the time slot port number through a network management system is unnecessary, and the error rate for allocating the time slot port number is decreased because no operator takes part in allocation process.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communication, in particular to a time slot port number allocation method, device and system. Background technique [0002] Optical Transport Network (OTN) technology is a new generation of transport network core technology, including the technical specifications of the electrical layer and optical layer, which can realize flexible scheduling and management of large-capacity services, and has increasingly become the mainstream technology of the backbone transport network . [0003] The original OTN standard (ITU-TG.709) defines three types of OTN containers: Optical Channel Data Unit (Optical Channel Data Unit, ODU for short) 1, ODU2, ODU3, the time slot type of which is 2.5Gb / s, and The rate levels of ODU1, ODU2, and ODU3 are 2.5Gb / s, 10Gb / s, and 40Gb / s, respectively, and contain 1, 4, and 16 time slots respectively. In order to enable OTN to support Ethernet and other new ser...
