Multiple Access Protocol over SONET/SDH (MAPOS) is a link-layer protocol for transmitting network-layer datagrams encapsulated in High-Level Data Link Control (HDLC) frames over Synchronous Optical NETwork/Synchronous Digital Hierarchy (SONET/SDH). This document describes an extension to the Node Switch Protocol (NSP) of MAPOS. NSP is a protocol for automatically assigning addresses to MAPOS network interfaces of nodes. The extension NSP+ enables the nodes to provide their directly connected switches with information about the multicast groups to which the MAPOS network interfaces of the nodes belong, so a switch forwards only required multicast frames to the network interfaces.
