摘要： Disclosed herein is a resource allocation method for providing load balancing and fairness for a dual ring. The resource allocation method includes the step of determining whether a bandwidth allocation request message is received from one of other nodes. If the bandwidth allocation request message is received, it is determined whether one or more of two rings of the dual ring fulfill a request of the bandwidth allocation request message. If the rings fulfill the request, a path is allocated to one of the rings having a lower weighted cost. A resource allocation information notification message is provided to other nodes. If the rings cannot fulfill the request, the process ends.

摘要： Disclosed herein is a shared Local Area Network (LAN) emulation method and apparatus. The method includes the following four steps. At the first step, a Logical Link Identifier (LLID) management table is set up to assign unique LLIDs to a plurality of Optical Network Units (ONUs) and manage the assigned LLIDs so as to identify the plurality of ONUs connected to a single Optical Line Terminal (OLT). Thereafter, a MAC address table is set up for the LLIDs to learn MAC addresses of the ONUs. Thereafter, the unique LLIDs are assigned to ONUs when the ONUs request registration from the OLT. Finally, data frames, which are received by a Shared LAN Emulation (SLE) layer of the OLT, are bridged using the LLIDs, VIDs of Virtual LANs to which the ONUs belong and destination MAC addresses of the data frames so as to provide a single matched port between a Logical Link Control (LLC) layer and a MAC layer of the OLT.
