Aggregating data traffic from access domains

摘要

According to one embodiment, a first message identifying a best root node of a spanning tree may be generated. The spanning tree may be implemented by an access domain. The message may be generated independently of a spanning tree protocol instance. The first aggregation node may transmit the first message to a plurality of access nodes of the access domain. Data traffic from the plurality of access nodes may be received. Each access node of the plurality of access nodes may implement a spanning tree protocol instance that selects the best root node as a root node of the spanning tree. The data traffic may be aggregated with other data traffic of a plurality of access domains, and the aggregated data traffic transmitted to an aggregation network.

1. A method comprising:
generating, by a first aggregation node that does not implement one or more instances of a spanning tree protocol instance, a first protocol message identifying a best root node of a spanning tree implemented by an access domain; transmitting, by the first aggregation node, the first protocol message to a plurality of access nodes of the access domain; receiving data traffic from the plurality of access nodes, each access node of the plurality of access nodes implementing a spanning tree protocol instance that selects the best root node as a root node of the spanning tree; and aggregating the data traffic and other data traffic of a plurality of access domains and transmitting the aggregated data traffic to an aggregation network.
