This module also implements some of extensions shown in "OpenFlow Extensions for 1. 3 Switch(Core switch) using Ling Aggregation, so as to be configured as single L2Switch network from 1. It also summarizes the OpenFlow features and supported forwarding actions, which are actions that OpenFlow can take when a packet matches the terms of a flow entry. For example, the Time-To-Live (TTL) field in the IP header can be decremented, which is unsupported in OpenFlow 1. 2: pages 21-25, 57-62 Instruction Processing Each flow entry of a flow table has a set of instructions to apply to all matching packets. Actions 14 Forward (output) Mandatory Forwarding of packet to physical or virtual ports Enqueue Optional Forward a packet through a specified queue attached to a port Drop Mandatory Implicit action associated with a flow-entry that has no specified action •Each flow entry has zero or more actions that determine how the switch handles matching. Of course, this offloading requires a translation between the OpenFlow specific messages to hardware related commands, which means to take the OpenFlow commands and map them to API calls inside of the switch. $ tshark -G protocols | grep -i openflow OpenFlow openflow openflow OpenFlow 1. 0:安全通道+单张流表+ipv4Openflow1. 3, the feature is using the Experimenter mechanism with the ONF Experimenter ID. 3 module for ns-3.
