Embodiment Construction

[0020] In order to make the object, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below with reference to the accompanying drawings and examples.

[0021] In the embodiment of the present application, a method for allocating IPv4 addresses for PTN end-to-end tunnels is provided. By dividing the IPv4 addresses in the IPv4 address pool into N network segments, any two adjacent network segments on an end-to-end tunnel When a network element allocates an IPv4 address, an IPv4 address different from the network number corresponding to the configured IPv4 address of the corresponding network element is allocated to each of the two network elements from the IPv4 address pool. It can automatically assign IPv4 addresses to network elements carrying end-to-end tunnels, saving labor costs, and avoiding the problems of repeated network addresses and repeated IPv4 addresses that are easy to occ...

Abstract

The present application provides a method and device for allocating IPv4 addresses for PTN end-to-end tunnels, the method comprising: configuring an IPv4 address pool, dividing the address pool into N network segments, and assigning a network number to each network segment; Each network segment corresponds to M IPv4 addresses; when assigning IPv4 addresses to any two adjacent network elements on an end-to-end tunnel, assign a corresponding network element configured IPv4 address to the two network elements from the IPv4 address pool. The IPv4 addresses corresponding to different network numbers are IPv4 addresses, and the IPv4 addresses assigned to the two network elements are different. This solution can automatically allocate IPv4 addresses for network elements carrying end-to-end tunnels, saving labor costs, and avoiding the problems of repeated network addresses and repeated IPv4 addresses that are easy to occur during manual allocation.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for allocating IPv4 addresses of the fourth version of the Internet protocol for end-to-end tunnels of a packet transport network (Packet Transport Network, PTN). Background technique [0002] PTN is a new generation of packet-based, connection-oriented multi-service unified transmission technology. While taking into account traditional time division multiplexing (TDM) services, it can better carry carrier-class Ethernet services, and can adapt to various types of services. It has a strong End-to-end networking capabilities. [0003] End-to-end management is an important part of PTN network management. End-to-end management is divided into three layers, tunnels, pseudowires, and services. End-to-end tunnels provide end-to-end connectivity and are the most basic layer. When creating an end-to-end tunnel, the automation of the creation process can simpli...
