Abstract: A system for interconnecting widely separated local area networks (LANs) (11,12) by means of a wide area network (WAN) (10) utilizes network level facilities to establish a connection through the wide area network and to create connection table entries at the WAN access point (13,14) which allow subsequent data frames to be transmitted through the wide area network without such network level operations. More particularly, the various LANs are combined into search groups, represented by address prefixes, to which LAN-initiated connection requests can be broadcast and which can respond so as to establish the data path connections. This system has the connection flexibility of a prior art router and, at the same time, the low overhead of a prior art bridge.

Abstract: PROBLEM TO BE SOLVED: To substantially reduce the overall power requirement of a line driver connected to a digital subscriber line DSL by limiting a bandwidth of a signal transmitted to all subscriber lines other than those connected to an intended recipient of a physical data frame. SOLUTION: A shared digital subscriber line modem achieves reduced total power consumption and aquires data security by generating and transmitting a physical data frame which includes a control channel and a data field to only the connected client modem associated with the intended recipient. A second physical frame which does not include the data field is generated and transmitted to all of the other connected client modems.

Abstract: PROBLEM TO BE SOLVED: To provide a mechanism for managing a register map for indirect register file access based on a map in a processor. SOLUTION: The management mechanism includes a register mapping including a map set, and each map of the map set has a plurality of map registers. An actual register set is accessed indirectly by the processor via map entries of the map set. The number of actual registers in the actual register set is larger than the number of map entries in the map set, and the map entries of the map set refer only to subsets of the actual register set at an optional time point. The mechanism includes the step of updating a plurality of map entries of at least one map of the map set in response to the execution of a single update instruction to manage update to a plurality of entries of the map set of the register mapping.

Abstract: PROBLEM TO BE SOLVED: To reduce electric power demand of the line driver of a DSL server modem, by limiting the bandwidth of signals to be transmitted to a related client modem (namely, limiting power in signals), excluding the case where a client is intending data reception in a current physical frame (not in idle state). SOLUTION: A low-power DSL modem transmitter suited for incorporation into an integral DSLAM server line card transmits all the power physical frame, including a control channel and a data field when there are data to be transmitted, and transmits a physical frame having only the control channel or the control channel and a low-power synchronous field, when there are no data to be transmitted. By regulating the flow of data packets to the DSL selectively, a method for controlling total power consumed in the integral DSLAM is provided.

Abstract: The process for determining the best communication route from a source end station to a destination end station is distributed over both source and destination network nodes. Network nodes, at the interface between a wide area network (WAN) and each subnetwork, contain access agents to control the communication flow between the wide area network and an end station in the subnetwork. The task of selecting the best route between two end stations is distributed between the access agents at the WAN interface in the first subnetwork, and the access agents at the WAN interface in the second subnetwork. Each access agent at one WAN interface obtains the best route from itself to the end station in its subnetwork. Each access agent at the other WAN interface finds the best route from each access agent at the first WAN interface through itself to the end station in its subnetwork. One designated access agent collects all the best route information. This best route information is concatenated, and the route with the least weight is selected as the best route between end stations.
