Link Aggregation provides protocols@ procedures@ and managed objects that allow the following: ?? One or more parallel instances of point-to-point links to be aggregated together to form a Link Aggregation Group (LAG)@ such that a Link Aggregation Client can treat the LAG as if it were a single link. ?? Conversation-sensitive Collection and Distribution (CSCD) that specifies a means to identify the distribution algorithm in use to assign frames to individual links in a LAG@ and to convey that information to the System at the other end of the LAG. ?? Distributed Resilient Network Interface (DRNI) that enables a LAG to terminate at a pair of cooperating Systems in order to provide system level as well as link level resiliency. Purpose Link Aggregation allows the establishment of point-to-point links that have a higher aggregate bandwidth than the individual links that form the aggregation@ and the use of multiple systems at each end of the aggregation. This allows improved utilization of available links in Bridged Local Area Network (LAN) environments@ along with improved resilience in the face of failure of individual links or systems. In applications connecting separately administered networks@ the networks are isolated from each other??s fault recovery events.
