  • Aggregating data traffic from access domains
    Patent number: 9553736
    Abstract: 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.
    Type: Grant
