Example Embodiment

[0044] The present invention will be described in detail below with reference to the drawings and specific embodiments.

[0045] In the embodiment of the present invention, in order to realize the coexistence and cooperation of multiple protocol stacks in the same system, it is first necessary to plan the multiple protocol stacks located in the same system, such as figure 1 As shown, specifically including:

[0046] Location planning: In multiple protocol stacks in the same system, plan a protocol stack facing the external network, and plan the remaining protocol stacks as the protocol stack used in the internal network;

[0047] Network planning: A private network is established between the various protocol stacks in the system, and the protocol stack used in the internal network and the protocol stack facing the external network communicate through the private network; the external public network passes through the external network The external address of the protocol stack communi...

Abstract

The invention discloses a method and a system supporting data forwarding among multiple protocol stacks in the same system. The method comprises the following steps of: in the same system, planning a protocol stack for an external network and planning other protocol stacks in the system to form protocol stacks for an internal network; establishing a private network among all protocol stacks in the system; and allowing the protocol stack for the external network to communicate with the protocol stacks for the internal network through the private network. The protocol stack for the external network has a sub-module for controlling forwarding; and when the external network accesses the special services of the protocol stacks for the internal network, or the protocol stacks for the internal network access the special services of the external network, the sub-module for controlling the forwarding filters out messages needing to be forwarded according to a configured network connection relation control table entry and forwards the messages after the translation of a network address. The method can solve the problem of coexistence and cooperation of the multiple protocol stacks in the same system.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and system for data forwarding between multiple protocol stacks in an MSAN (Multi-Service Access Node, multi-service access node) system. Background technique [0002] Under the combined effect of market competition and technological progress, the telecom industry is undergoing profound changes unseen in a century. On the one hand, the popularity of new communication technologies such as mobile communications, IP telephony, and e-mail has led to the diversion of fixed-line services, which has led to a general decline in the income of global fixed-line operators, forcing traditional telecom operators to shift to integrated information services. On the other hand, the continuous progress and accumulation of communication technology over the years has laid a solid foundation for business and network transformation. The development of IP technology makes it possible for ope...
