Simulated evaluation system for mapping mechanism under IPv6 (Internet Protocol version 6)

Abstract

The invention provides a simulation evaluation system of a mapping mechanism under IPv6, comprising: a data processing module, including: an acquisition sub-module for obtaining the direction attribute of a data packet for input original data; a conversion sub-module for converting The data packet is converted from IPv4 format to IPv6 format; the encapsulation router module includes: a mapping query sub-module, which is used to determine whether the mapping information is hit in the cache when receiving the data packet, and if not, send a query to the distributed mapping system , and trigger the discarding submodule; the discarding submodule is used to perform the discarding operation of the data packet according to the direction attribute; the distributed mapping system module is used to respond to the query according to the instantiated distributed mapping system; record A module, configured to obtain and record the mapping cache hit information of the encapsulation router module, and the query response information of the distributed mapping system module. The invention is used to realize the evaluation of the conventional function of the mapping mechanism under the IPv6 edge network address.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a simulation evaluation system of a mapping mechanism under IPv6. Background technique [0002] With the development and growth of the Internet, the problem of routing scalability is becoming more and more serious: the exponential expansion of the core routing table and the update of the global routing system widely affect the stability of the routing system; the root cause of the routing scalability problem is the IP address Multiple semantics such as user ID, user location ID, and user routing ID are overloaded; edge networks require multi-homing, traffic engineering, and other reasons, so that a large number of edge routes enter the core routing table, which contradicts the core network's requirements for route aggregation. [0003] The separation scheme is an effective way to solve the problem of routing scalability. It separates the edge network address from th...

Problems solved by technology

[0005] However, the evaluation methods of the existing mapping mechanism are mainly aimed at the performance of the local cache of the encapsulation router (ITR, Ingress Tunnel Router), or are limited to the mapping mechanism under the IPv4 (Internet Protocol Version 4, Internet Protocol Version 4) edge network address, and There is a lack of evaluation of the general performance of the mapping mechanism for IPv6 (Internet Protocol Version 6) edge network addresses
