802.1AXbq - Link Aggregation Amendment: Distributed Resilient Network Interconnect
The full title of this PAR is "Standard for Local and Metropolitan Area Networks - Link Aggregation Amendment: Distributed Resilient Network Interconnect".
This amendment enhances Link Aggregation, its protocols, procedures and managed objects, to provide a resilient interconnect using multiple links among one or more nodes in a network and one or more nodes in another, separately administered, network. The Distributed Resilient Network Interconnect (DRNI) preserves the Link Aggregation model of establishing a single logical link consisting of multiple links, and will be backward compatible with existing conformant implementations of Link Aggregation. The DRNI will specify a means to ensure that frames belonging to any given service will use the same physical path in both directions between the two networks.
The purpose of this amendment is to enhance Link Aggregation so that a set of physical and/or virtual bridge components or end stations provide a redundant connection between two separately administered networks. The DRNI enables the independence of the networks' management and control protocols, isolates each from the other's fault recovery events, and can forward data frames belonging to any given service over the same physical path in both directions between the two networks.
There is a need to enhance Link Aggregation, its protocols, procedures and managed objects, to provide a resilient interconnect using multiple links among one or more nodes in a network and one or more nodes in another, separately administered, network.
