Class DefaultGroupBucket

java.lang.Object

org.onosproject.net.group.DefaultGroupBucket

All Implemented Interfaces:

GroupBucket, StoredGroupBucketEntry

public final class DefaultGroupBucket
extends Object
implements GroupBucket, StoredGroupBucketEntry

Group bucket implementation. A group bucket is collection of instructions that can be performed on a traffic flow. A select Group can have one or more Buckets where traffic will be processed by a single bucket in the group, based on device specific selection algorithm (e.g. hash on some fields of the incoming traffic flows or round robin) and hence can contains optional weight field to define the weights among the buckets in the group. A failover group bucket is associated with a specific port or group that controls its liveness.
