Abstract: Apparatus and methods for reducing latency in coordinated networks are provided. The apparatus and methods relate to a protocol that may be referred to as the Persistent Reservation Request (“p-RR”), which may be viewed as a type of RR (reservation request). p-RR's may reduce latency, on average, to one MAP cycle or less. A p-RR may be used to facilitate Ethernet audiovisual bridging. Apparatus and methods of the invention may be used in connection with coaxial cable based networks that serve as a backbone for a managed network, which may interface with a package switched network.

Abstract: A Wireless Local Area Network (WLAN) system based upon peer-to-peer communications. A wireless terminal for peer-to-peer communications acts either as a WLAN master or as a WLAN slave. When the wireless terminal acts a master, the wireless terminal undertakes mastering duties that include transmitting a beacon interval in the frame cycle. When the wireless terminal is not tethered to a power source, mastering duties alternate according to a round-robin WLAN mastering cycle, wherein the wireless terminal acts the WLAN master during at least one frame cycle and acts the WLAN slave during other frame cycles to conserve an untethered power source of the wireless terminal.
