Abstract
Methods and apparatus for enabling a layer 2 node associated with an open systems interconnection (OSI) reference model to perform resource reservation protocol (RSVP) processing are disclosed. According to one aspect of the present invention a layer 2 device associated with an OSI reference model includes a first interface, a processing arrangement, and a second interface. The first interface intercepts a message associated with a on-path signaling protocol for at least one selected from a group including resource reservation and admission control at a layer above layer 2. The processing arrangement processes the message, and the second interface sends the message.
