Abstract

The invention discloses an optimization method for defining flow interaction in an IPv6 transition scenario based on software. The method comprises two aspects of control plane flow transfer and data plane flow transfer. According to the flow optimization method provided by the invention, a flow interaction load can be effectively reduced, and the forwarding efficiency of the conventional transition technology is obviously improved, so that sustainable development of the IPv6 transition technology is promoted; the method disclosed by the invention is applicable to major transition technologies comprising DS-Lite, Public 4over6, Lightweight 4over6, MAP-E, NAT64 and the like.

Description

technical field

[0001] The invention belongs to the technical field of the Internet, in particular to a flow interaction optimization method based on software-defined IPv6 transition. Background technique

[0002] With the rapid development of the Internet, IPv4 address resources have been exhausted, and the global IPv4 address space has been allocated in February 2011. IPv6 has become an effective solution to completely solve the shortage of address space. Due to the incompatibility between IPv6 and IPv4, how to smoothly transition from IPv4 to IPv6 has become the focus of both academic and industrial circles.

[0003] Currently, popular IPv6 transition technologies include DS-Lite, Public 4over6, Lightweight 4over6, MAP-E, NAT64, etc. The use scenarios of each transition mechanism are inconsistent, the compilation methods are not uniform, and the flow granularity is greatly different, which leads to the inability to flexibly deploy transition technologies and the poor ver...
