Openflow Specification - an overview ScienceDirect Topics

WebOpenFlow is a programmable network protocol that manages and directs traffic among Ethernet switches, routers, and wireless access points over the network in support of Software-Defined Networking (SDN) applications. OpenFlow enables network controllers to determine the path of network packets across a network of switches. The controllers are distinct from the switches. This separation of the control from the forwarding allows for more sophisticated traffic management than is feasible using access control lists (ACLs) and routing protocols. Also, OpenFlow allows switches from different vendors — often each with their own proprietary interfaces and scripting languages — to be managed remotely u… greenleaf laboratoryWebOpenFlow, NETCONF, OpenConfig, its system architecture is not directly tied to them. 2.

Open Flow Switch: What Is It and How Does It Work

Webport. OpenFlow ports have limited state such as \up", \down" and whether spanning tree ood packets should be forwarded out the port. Additional con- guration of ports may handled by the OpenFlow con guration protocol. There are several OpenFlow virtual ports used to indicate, for example, ooding or the ingress port (see 3.3). 3 Flow Table WebOpenFlow flows are defined by various elements. Table 1 outlines the support for flow elements in OpenFlow v1.0 and OpenFlow v1.3.1. The elements supported by the OpenFlow versions uniquely identify a flow. Flow entries specify wildcard match conditions for fields that do not require an exact match.
