Abstract

The invention discloses a method and system for acquiring and processing a multiplexing address and a port range. The method comprises the following steps: a client side at a user side sends a port acquiring request to a server side at a network side through a PCP-PR (Port Control Protocol-Port Range); the server side selects the port range which is allocated to the client side for use from a port address pool, wherein the port address pool comprises ports which are not distributed yet; and the server side returns a port acquiring response message to the client side through the PCP-PR, records a current port allocation entry in a local state table, updates the port address pool and deletes the port range from the port address pool, wherein the port acquiring response message comprises an IPv4 (Internet Protocol Version 4) multiplexing address and the port range, and the current allocation entry comprises corresponding relationship information of an IPv6 (Internet Protocol Version 6) address, the IPv4 multiplexing address and the port range. The method and system disclosed by the embodiment of the invention can ensure that the available port range and the multiplexing address can be acquired at the user side.

Description

technical field [0001] The invention relates to communication technology, in particular to a method and system for acquiring and processing multiplexed address and port ranges. Background technique [0002] At present, the fourth version of the Internet Protocol version (hereinafter referred to as: IPv4) addresses have become more and more scarce. According to the address usage data of the Internet Assigned Numbers Authority (hereinafter referred to as: IANA) in the last three years, It is predicted that global IPv4 address resources will be exhausted around the end of 2011. In my country, the shortage of IPv4 addresses is particularly serious. Insufficient address space will certainly hinder the further development of the Internet. In order to expand the address space, the prior art redefines the IP address space through the sixth version of the Internet Protocol (hereinafter referred to as: IPv6). [0003] In a variety of transition schemes from IPv4 to IPv6 (hereinafte...
