STRUCTURE FOR IMPLEMENTING OPENFLOW ALL GROUP BUCKETS USING EGRESS FLOW TABLE ENTRIES

摘要

An embodiment of the invention includes an Openflow switch. The Openflow switch includes Openflow ALL groups. The Openflow ALL groups include ALL group buckets. During ingress ALL group buckets are represented in ingress as a list of output ports with associated queue ID's and associated copy-counts. Each ALL group bucket is represented in egress by an egress Openflow table entry where the egress Openflow table entry matches a group ID and a bucket ID. An action entry in an ALL group bucket table entry is the set of actions in the Openflow ALL group bucket excluding an output port and queue assignment.

1. An Openflow switch comprising:
Openflow ALL groups wherein the Openflow ALL groups comprise: ALL group buckets; wherein ALL group buckets are represented in ingress as a list of output ports with associated queue ID's and associated copy-counts; wherein each ALL group bucket is represented in egress by an egress Openflow table entry wherein the egress Openflow table entry matches a group ID and a bucket ID; and wherein an action entry in an ALL group bucket table entry is the set of actions in the Openflow ALL group bucket excluding an output port and queue assignment.
