摘要： Data structures, a method, and an associated transmission system for multicast transmission on network processors in order both to minimize multicast transmission memory requirements and to account for port performance discrepancies. Frame data for multicast transmission on a network processor is read into buffers to which are associated various control structures and a reference frame. The reference frame and the associated control structures permit multicast targets to be serviced without creating multiple copies of the frame. Furthermore this same reference frame and control structures allow buffers allocated for each multicast target to be returned to the free buffer queue without waiting until all multicast transmissions are complete.

摘要： System and method for fully transparent IP mobility services for clients in a dynamic LAN Ethernet environment. The functionality within a proxy server, a combination of network address translation, proxy address resolution protocol, and proxy domain name service, allow the proxy server to support and provide full IP client functionality to any IP-enabled network device in any proxy server enabled LAN. The proxy server may be added to an existing Ethernet (or Ethernet-emulated) LAN. Once configured with the necessary subnet range, DNS, and IP pools, the proxy server provides support for any mobile device that enters the LAN.

摘要： A device that automatically configures the high speed (100 Mbps) port of a switch both physically and logically is provided. For physical configuration, the device determines the transmit pair conductor and the receive pair conductor interconnecting a switch port and Data Terminal Equipment (DTE). The switch port can be termed “Primary” while the connected DTE is termed “Secondary” or vice versa. For logical configurations, the device makes the determination. The device includes a switching relay, a controller and impedance matching transformers. The controller switches the connections between the relay and the transformer so that the impedance is substantially constant even though the output from the high speed port is feeding different resistive transmission lines.

摘要： A network switch configured for switching data packets across multiple ports uses decision making logic to generate frame forwarding decisions. The switch buffers data frame header information in an internal memory for processing by the decision making logic. The switch employs a modular architecture that enables the decision making logic to perform its processing independently from other logic functions of the switch.

摘要： A system and method of increasing message throughput in a communications system utilizing priority management, conglomeration and compression, TCP retransmission filtering and pull transmission. The priority manages ranks the messages in a message queue as a function of the priority and time to live of each message. The conglomerator conglomerates messages into assemblies destined for the same destination radio. The TCP filter prevents the retransmission of successfully received messages. The messages are transmitted as a function of the availability of the destination radio to receive.

摘要： A router and method for routing table cache population technique is disclosed. In particular, the illustrative embodiment routes packets through it more quickly than comparatively expensive routers in the prior art. The present invention recognizes that a fast router has small routing table cache that has a high hit ratio and that a high hit ratio can be achieved with a small routing table cache by predicting which entries will be needed in the routing table cache in the future and by populating the routing table cache with those entries before they are needed. The illustrative embodiment of the present invention comprises: an input port for receiving a succession of packets, wherein each of the packets comprises a destination address; a plurality of output ports; a switching fabric for interconnecting the input port to each of the plurality of output ports; a processor or building a temporal model of the occurrence of the destination addresses at the input port, for populating the routing table cache based on the temporal model and at least one entry that is stored in a routing table, and for routing at least one of the packets from the input port to one of the output ports through the switching fabric based on the entry that is stored in the routing table cache.

(4) Multiplexing the live media unit sequence and the plurality of delayed media unit sequences to generate a multiplexed sequence. (5) Transmitting the multiplexed sequence to at least one end user.

摘要： Scheduling circuitry, for use for example in an ATM network unit to schedule cell transmissions, includes a master calendar (1) for holding entries corresponding respectively to events (cell transmissions) that are to occur within a preselected master-calendar scheduling range (SR), and a slave calendar (12) for holding entries corresponding respectively to events that are to occur beyond that scheduling range. When an event is to be scheduled, calendar control circuitry (24) makes an entry corresponding thereto in the slave calendar (12) if the interval between a current time and a desired scheduling time for the event exceeds said scheduling range. The entry in the slave calendar includes timing information representing the desired scheduling time. The calendar control circuitry monitors the entries in the slave calendar (12) and causes an entry therein whose corresponding event becomes within the scheduling range to be transferred to the master calendar (1). Such scheduling circuitry can deal effectively with events that are to be scheduled at widely disparate intervals (very short and very long) without requiring the calendars to be large and without complicated processing of the calendar entries.

摘要： A network router has a distributed processing scheme for multicast packets. The router has a look-up and forwarding engine operative in response to the reception of an internet protocol multicast packet to direct the packet to a multiplicity of transmit ports which may or may not be connected to the source network segment from which the multicast packet was received by the router. Each transmit port is associated with a predetermined default network segment and the engine directs the packet to the ports (e.g. across the router's backplane) with an identification of the source network segment and control flags which enable processing means associated with the ports to determine by comparison of the respective network segment and the source network segment whether the packet is bridged from the respective port or routed, with relevant modification of the packet, from that port. The control flags comprises a first flag which can be set to allow the relevant modification and a second flag which can be set to allow the comparison between the source segment and the predetermined default segment.
