摘要

Procedure link management level data link for communications networks, routing method of data frames, device networking and network combining both procedures.; This link management level data link (OSI Layer 2) comprises a method for constructing a tree of hierarchical expansion from a network bridge (bridge) chosen as root, which hangs at least one network bridge connected to said root through a designated port and a local hierarchical MAC address (HLMAC) corresponding to the designated port identifier is assigned. Frames with a destination address are routed HLMAC by a method using hierarchical tree expansion. All bridges (Christen here as bridges combined) that hierarchical local MAC address assigned may also processing frames with universal MAC addresses assigned to the destination terminal. This hierarchical tree is constructed with the standard tree (802.1D), forming a mixed tree expansion bridges comprising both combined as conventional operating under 802.1D.
