Abstract

The invention discloses an OpenFlow-based SDN virtualization platform upstream signaling flow label processing method. The data packet is received; when the physical switch receives the data packet, the flow table in the physical switch is firstly inquired. If the flow table does not exist with the data packet If there is a matching entry, the packet header is encapsulated in the uplink signaling and sent to the network virtualization platform; the network virtualization platform acts as the controller of the physical switch; the network virtualization platform receives the submitted data packet; judges the data packet Whether it has a flow label; if the data packet has a flow label, it indicates that the data packet is a data packet inside the virtual network; if the data packet does not have a flow label, it indicates that the data packet is an unclassified data packet.

Description

Technical field

[0001] The invention belongs to the technical field of computer networks, and specifically relates to an OpenFlow-based SDN virtualization platform uplink signaling flow label processing method. Background technique

[0002] With the rapid development of Internet technology, the number of Internet applications and users has increased rapidly, and the Internet based on TCP / IP has gradually exposed many problems and drawbacks. Many countries have proposed next-generation Internet plans, and software-defined networks have emerged.

[0003] The OpenFlow software-defined network consists of two parts: the data plane, used to forward network data packets; the control plane, used to control the forwarding strategy of network data packets. The OpenFlow switch of the data plane maintains a flow table internally, which is called a virtual network flow rule description table. The virtual network flow rule description table can be matched according to the characteristics of t...
