Abstract: This memo describes the LLRMP, a lightweight link level signalling protocol used to setup resources in shared medium and bridged or switched LANs. Network layer resource management protocols like RSVP or STII, or a local network manager, may invoke the LLRMP to request a certain quality of service over a bridged LAN. The LLRMP protocol supports a distributed admission control over each shared medium segment within the bridged LAN. Each node running the protocol has knowledge about the resources reserved on its local network segment. Resources are reserved independently on each segment, as a LLRMP reservation message travels along the data path from the source to the receiver.
