The Cluster Membership object
Table of Contents
The membership component in the Apache Tribes Channel is responsible for dynamic discovery of other members(nodes) in the cluster.
The default implementation of the cluster group notification is built on top of multicast heartbeats
sent using UDP packets to a multicast IP address.
Cluster members are grouped together by using the same multicast address/port combination.
Each member sends out a heartbeat with a given interval (
frequency), and this
heartbeat is used for dynamic discovery.
In a similar fashion, if a heartbeat has not been received in a timeframe specified by
ms. a member is considered suspect and the channel and any membership listener will be notified.
