Problems solved by technology

[0006] This solution has the following problems: it still does not support the mapping of the call COS to the end-to-end connection that carries the call; the call and the connection are implemented using the same signaling, it is difficult to realize the independent function of the call and the connection, and it is difficult to realize the call between different nodes request; modification of call COS is not supported

Embodiment 1

[0087] Embodiment 1: The calling node A initiates a call request to the called node Z, and the connection operation corresponding to the calling COS is to create a new connection. In the process of this embodiment, Figure 5 The functions of each node on the control plane are: node A is the calling controller, node Z is the called controller, node B is both the calling side network controller and the connection controller, and node D is the called side network controller. It is called the function of side network controller and connection controller. Node C and node E are intermediate nodes, which do not participate in call processing, but only participate in the connection processing process as connection controllers.

[0088] The specific process of this embodiment is as follows Figure 6 shown, including the following steps:

[0089] Step 601: Node A sends a Notify message to Node B as a call request. In addition to carrying standard call parameters, the Notify me...

Embodiment 2

[0111] Embodiment 2: The call COS is modified between the calling node A and the called node Z.

[0112] The specific process of this embodiment is as follows Figure 7 shown, including the following steps:

[0113] Step 701: Node A sends a Notify message to Node B as a call request. In addition to standard call parameters, the Notify message also carries a newly added COS object;

[0114] Step 702: Node B finds that the new call parameters are different from the locally saved call parameters, considers it a call modification operation, and maps the call COS value in the call request to a specific connection operation and connection according to the local mapping table and user policy data. parameters, and generate call negotiation parameters according to the connection operation and connection parameters:

[0115] If a new connection is added during the call, the call controller of Node B selects the source SNP, bandwidth, protection type, etc. of the new connect...

Abstract

A method for mapping COS to connecting of load-carry call includes sending a calling request with call COS to calling side NCC by calling controller, obtaining relevant call consultation parameter by calling side NCC according to said call COS and sending said parameter to called side NCC, carrying out consultation on said parameter from calling side NCC by called side NCC, returning consulted out call parameter back to calling side NCC and triggering connection operation corresponding by calling side NCC according consulted out call parameter returned from called side NCC.

Description

technical field [0001] The invention relates to the field of network technology, in particular to a mapping method for implementing call service levels to connections bearing calls. Background technique [0002] With the rapid development of data services and leased line services, the demand for network bandwidth continues to increase, and the requirements for dynamic allocation of network bandwidth are becoming more and more urgent. The network needs to be able to provide dynamic provisioning capabilities, support mesh network structures, and have Flexible expansion capability and fast protection recovery function. However, the service scheduling of the traditional optical network adopts the static configuration method of the network management, does not support the dynamic provisioning method, and mostly adopts linear or ring networking, and the protection and recovery adopts multiplex section protection and sub-network connection protection (Sub-Network Connection Protect...
