Patent CA-2334442-C (CA)
Inventor: QUINLAN SEAN
IPC: H04N7/26
Filed: 2001-02-07
Granted: 2005-07-26
Abstract: A method and apparatus for compressing packets that enables inter-packet compression thereby achieving greater robustness and increased compression ratios without the deleterious effects, e.g., the effect of packet loss multiplying, of prior compression schemes. More particularly, a so-called acknowledgment scheme is employed in conjunction with the specific compression algorithm such that the transmitter, i.e., sender, can limit the history used by the compression algorithm to those packets that are correctly received. In particular, a vector identifying the packets used as the history is included in the compressed packet thereby enabling the receiver to reconstruct the packet history state necessary to decompress the packet.  Advantageously, increased robustness and greater compression ratios are achieved independent of any particular one compression scheme.

Title: Method and system for burst congestion control in an internet protocol network
Inventor: GERSHT ALEXANDER
IPC: H04Q11/04
Filed: 1999-08-27
Granted: 2008-01-15
Abstract: A method and system for controlling congestion in an IP network (160) comprises the steps of preallocating, for a predetermined interval of time, a set of burst access parameters to a set of predetermined routes between a set of source node (100a) and destination node (100c) pairs in the IP network (160) and controlling at the burst level.  Specifically, a network controller (120) for a predetermined interval of time, determines a set of routes between each source-destination node pair in the network, preallocates a set of maximum permitted rates to the predetermined set of routes, respectively, and pre-assigns a set of burst access thresholds to a set of service classes, respectively, in the predetermined routes, where the pre-assigned burst access thresholds are less than or equal to the corresponding preallocated maximum permitted rates. Based on the maximum permitted rates and the burst access thresholds, each source node (100a) in the network (160) then controls, at the burst level, the traffic accessing the network and reserves for each admitted burst the burst peak packet rate on a predetermined route, without communicating with other nodes in the network.
