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.

Abstract translation: 根据一个实施例，可以生成标识生成树的最佳根节点的第一消息。 生成树可以由访问域来实现。 消息可以独立于生成树协议实例生成。 第一聚合节点可以将第一消息发送到接入域的多个接入节点。 可以接收来自多个接入节点的数据业务。 多个接入节点的每个接入节点可以实现选择最佳根节点作为生成树的根节点的生成树协议实例。 数据流量可以与多个接入域的其他数据业务聚合，并且聚合的数据业务被发送到聚合网络。
