Problems solved by technology

However, the defect of this solution is that it will prolong the switching time of waiting for services in the queue. The later in the queue, the longer the switching time of services, and it cannot fully utilize the characteristics of fast recovery of ASON network services.

Embodiment Construction

[0024] Embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0025] Such as figure 1 with figure 2 As shown, the method for concurrent processing of large traffic in the automatic switching optical network of the present invention comprises the following steps:

[0026] A1. First, a parallel processing area is set for the service source network element 1, and the parallel processing area is the number of services that can enter the signaling processing flow at the same time. At both ends of the parallel processing area, the business on the left is the business that has completed the signaling processing flow, and the business on the right is the business waiting to be processed; the signaling processing stage of the business in the parallel processing area is divided into two parts: Sending signaling packets waits for the corresponding area and prepares to send signaling packets area.

[0027] A2. At...

Abstract

The invention provides a high-service volume concurrent processing method in an automatically switched optical network (ASON), relating to the field of ASON. In the method, by setting a concurrent processing area and the volume of concurrent processing services, the number of the services entering into a signaling processing procedure simultaneously is restrained; the services which need processing enter into the concurrent processing area firstly; and the services in the concurrent processing area are removed out of the concurrent processing area after being processed, and queuing services enter into the concurrent processing area in sequence, thus avoiding overlong service switching time caused by simple queuing and avoiding service processing failures caused by network congestion, multi-retransmission of signaling messages, inaccurate real-time data of routing calculation and the like, reducing service switching time, and realizing the high-service volume concurrent processing.

Description

technical field [0001] The invention relates to the field of automatic switching optical network, specifically a method for concurrent processing of large traffic in automatic switching optical network. Background technique [0002] With the demand for flexibility in service scheduling in the optical network, Automatically Switched Optical Network (ASON, Automatically Switched Optical Network) emerges as the times require. One of the main advantages of ASON is that due to the addition of the control plane, the automatic and flexible processing of services can be realized. The signaling response message returned by the service source network element to the service sink network element indicates the completion of the processing process, which includes: service establishment and deletion, dynamic recovery in case of business failure, and automatic return after the failure is cleared. The ASON control plane processes the business in parallel. The source of the business sends si...
