摘要： A method and apparatus is provided for searching a knowledge base to determine whether a search object matches any of a plurality of knowledge base entries. When the knowledge base includes a partially matched entry, the group of partially matched entries (elements (3, 5, 7, 9, and 11) in the figure) is identified. Thereafter, at least one previously unselected search object bit is selected and examined to determine whether the group of partially matched entries includes a further matched entry the represents the same bit pattern in its bit that corresponds to the previously unselected search object bit and when it does not, the search is terminated indicating no match.

摘要： An asymmetric network communication system for use in a client-host environment having independent forward and return channels operating at different speeds and/or under different protocols on the same or different communication media to provide efficient utilization of shared resources. A network manager, such as a hybrid access system, effects transmission of packetized data on a forward (downstream) channel from the host server to multiple client devices coupled with a shared downstream media at 10 or more megabits per second while simultaneously providing selectable multiple lower speeds of operation on shared or dedicated return (upstream) channels from the client devices to the host server depending on bandwidth availability, bandwidth demand, service level authorization, etc, for the return channel. Forward and return channels may be located on the same or different communication medium including a CATV network, direct broadcast satellite network, television or radio RF broadcast network, wireless or mobile cellular facilities or the like. The return channel may reside on a PSTN either directly coupled with the host server or connected with the network manager for subsequent transmission to the host server. The network manager handles or controls the forward and return communication to establish asymmetric communication between the host and plural client devices in a way to pre-authorize the amount of upstream data sent by a remote client.

摘要： In a managed repeater (10) having an address learn capability wherein receipt at a particular port (30) of a data packet having a received source address different from a stored source address associated with the particular port replaces the stored source address with the received source address, a source address locking circuit includes an address learn circuit associated with the particular port, for replacing the stored source address with the received source address when the stored source address does not match the received source address, and an address lock register for the particular port, coupled to the address learn circuit, for storing a bit value to disable the address learn circuit from replacing the stored source address with the received source address. This managed repeater provides improved security in a network having source address updating by allowing an administrator to disable the source address update for a particular port in the managed repeater. Each address lock register is externally programmable, and the administrator is able to program time windows to disable source address updating for a particular port. The administrator may program each address lock register independently to prevent the stored source address associated with each port from being updated. The managed repeater allows the administrator to determine on a per port basis whether the managed repeater's address learning capability should be enabled or disabled for a programmable time window.

摘要： The invention provides a method for segregating traffic amongst a plurality of stations that are associated with an access point, comprising the steps of providing a distribution system comprising multiple virtual local area networks (VLANs), wherein every station that associates with said access point can create a new VLAN with itself and said distribution system as its members, wherein a creator of a new VLAN can authenticate stations that wish to join said new VLAN; and separating traffic between trusted and untrusted stations even though they associate with a same access point.

摘要： A bridge (60, 61, 62) capable of reducing unwanted WAN multicast packet traffic in a LAN (40) is disclosed. The bridge (60, 61, 62) examines the contents of WAN multicast query and report packets and includes this information in its filtering database (88). The bridge (60, 61, 62) designates ports (80a, 80b, 80c, 80d, 80e) on which query packets are received as query ports. When there is no WAN router (64, 66) generating multicast query packets into the LAN (40), the bridge (60, 61, 62) simulates the behavior of a WAN router (64, 66) and generates WAN multicast query packets so as to cause report packet generation by end systems (50, 51, 52). A timeout interval for undesignating query ports and a method for determining an appropriate timeout for a port is disclosed.

摘要： A programmable arbitration system including control logic to select one of several arbitration schemes for selecting the ports of a network switch, a memory to store priority values indicating the relative priority of each of the ports, monitor logic to monitor each of the ports and to program the priority values in the memory based on a priority scheme selected by the control logic, and arbitration logic to select a port having the next highest priority. The arbitration schemes preferably include a round-robin priority scheme, a first-come, first-served (FCFS) priority scheme, a weighted priority scheme, or any other desirable priority scheme. The monitor logic includes polling logic to periodically poll the ports and to program a priority value of each port. The memory includes receive and transmit lists to indicate of which of the ports have indicated needing service and a corresponding priority value. The arbitration logic includes a receive arbiter and a transmit arbiter, each of which use a corresponding arbitration count.
