Abstract: A MANET protocol, comprising: receiving a data packet (DP) from a current sender (CS) by a recipient, defining: an identity of the CS, a prior sender (PS) from which CS received DP, and a target recipient (ID), a count (HC) of hops previously traversed by DP, and a sequence identifier (SI); updating a forwarding table (FT) to mark CS as being reachable in one hop, and PS as being reachable in two hops via CS as next hop; determining if ID is the recipient; determining whether to rebroadcast by recipient, if and only if the SI is not present in a list of prior SIs; and selectively rebroadcasting DP by recipient in dependence on said determining, modified by: replacement of CS with an identity of the recipient, PS with CS, and ID with a next hop from the FT if present, and incrementing HC.

Abstract: A mesh network protocol, comprising: receiving a packet from a sender, identifying the sender, a prior sender, a flood mode, a time-to-live, and a sequence identifier; marking the recipient as critical if during a full flood period, the recipient is the same as the prior sender, and marking the recipient as non-critical if no packet is received with the recipient the same as the prior sender; rebroadcasting the packet, modified by updating sender with the recipient, and sender as prior sender, decrementing the time to live until expiration, and, the identity of the recipient is different from the identity of the prior sender in full flood mode; or the identity of the recipient is different from the prior sender, and the recipient is critical, in partial flood mode.

Abstract: A system and method for managing congestion in a multi-hop wireless network, employing congestion notification messages. The technology has three main components: a mechanism at the Medium Access (MAC) layer for determining when a given source or transit node is deemed congested; a mechanism at the Network Layer (NL) determining how to propagate this information to applications, including suitably combining overload indications received from neighbors; and a mechanism at the Transport Layer (TL) of each source of traffic for determining when a source is generating excessive traffic, and combining it with Medium Access Control (MAC)-based overload indication from downstream nodes, thus providing a multi-layer approach to traffic throttling.

Abstract: The present invention relates to methods and apparatuses for extending the benefits of vectoring technology to xDSL systems including disparate types of xDSL lines. In embodiments, the invention includes a scheme to match the symbol frequencies of ADSL2 and VDSL2 lines, to then enable vectoring of ADSL2 FEXT into VDSL2 lines.

Abstract: A system and method for canceling noise in a received signal are provided. A signal is received at a receiver comprising a frequency domain equalizer (FEQ). A noise prediction error of the signal is determined. The FEQ is updated with the noise prediction error, wherein the act of updating mitigates the effect of noise in the signal.
