NETWORK VIRTUALISATION METHOD, COMPUTER-READABLE MEDIUM, AND VIRTUALISATION NETWORK

摘要

Network virtualisation method, computer-readable medium, and virtualisation network 5 Disclosed is a network virtualisation method, comprising: receiving a virtual flow entry in respect of a virtual link (vL3); and providing a physical flow entry relating to the virtual flow entry in respect of a physical loopback link (loopLink1) mapped to the virtual link (vL3) for causing a packet flow matching the physical flow entry to be forwarded via the physical loopback link (loopLink1) with an 0 identifier of the virtual link (vL3). The physical loopback link (loopLink1) corresponds to a pair of physical ports of a physical switch (pS1).
