Embodiment Construction

[0046] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described below are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0047] When the present invention carries out PTN network planning, design and optimization, described PTN network has the following characteristics:

[0048] (1) The topology of the PTN network is known according to the actual application, including the number of nodes and the connectivity of the nodes.

[0049] (2) For the bandwidth requirements of the business, each network node has the ability to allocate wavelengths completely.

[0050] (3) The PTN network equipment has a control plane, so as to support the switching of the service working path to the protection path when it is affected.

[0051] (4) The P circle in the network refers to the LSP tun...

Abstract

The invention discloses a method and a device for protecting PTN network services, and relates to a PTN network service planning technology based on P-cycle protection in communication network planning and design. The method includes: traversing each service in the PTN network service set, establishing a service path for each service route, and obtaining N service paths corresponding to the N services; Each link is configured with a protection circle suitable for multi-service; it is characterized in that: for the configured protection circle of any link traversed by multiple service paths in the N service paths, two protection paths are established, so that the two protection paths are The protection paths respectively provide protection for the link service sets of the protection circle. The invention can make use of the inseparable characteristics of PTN service flow and the advantages of high protection efficiency of the P-circle, and configure the P-circle protection of two protection paths for the spanning link, thereby improving the utilization rate of the network bandwidth.

Description

technical field [0001] The present invention relates to the technical field of combining network planning technology with computer applications, in particular to the PTN network service planning technology based on P-cycle protection in communication network planning and design, that is, to make the services in the PTN network meet the P-cycle protection, and at the same time A planning method and device for improving the utilization rate of network bandwidth, which minimize the required capacity of the configured P-cycle and provide the largest protection capability. Background technique [0002] Packet Transport Network (PTN: Packet Transport Network) is a new generation of packet-based, connection-oriented multi-service transport technology. TDM: Testing Data Management / Technical Data Management) business. In the metropolitan area network of Chinese operators, PTN technology is mainly positioned at the convergence access layer of the metropolitan area. The main services ...
