摘要： A system and method of mapping a host computer address space into a network interface adapter (NIA) address space. A network interface processor within the NIA requests a memory allocation from the host computer. The host computer responds with an assigned base address in the host computer address space, and a length defining the contiguous addresses within the host computer address space equal to the allocation requested by the NIA processor. A hardware trap is set such that an interrupt to the NIA processor is generated when the host computer attempts to access data at an address within the allocated address range of host computer contiguous addresses. The network interface processor translates the received host address to a physical address within the NIA address space, reads the data at the respective NIA physical address, and transfers the data to the host computer.

摘要： A system and methods are shown for selecting a packet data serving node (PDSN) for a mobile node in an Internet Protocol network. A network node receives a message associated with a mobile node. The message includes a service request parameter corresponding to a requested service. The network node uses the service request parameter to select the address of a packet data serving node (PDSN) offering the service. The network node then sends a response message directing a connection with the selected PDSN. The service request parameter may be an international mobile subscriber identifier (IMSI) that identifies a subscriber requesting a static IP address, in which case the network node directs a connection with a PDSN that offers an. Internet connection with the static IP address.

摘要： A system of switch modules comprises input demultiplexers connected to ports on each of the modules and output multiplexers connected to each of the modules. Each module has output and input interfaces for mesh links and at least one output interface is looped back to an input interface on the same module. The arrangement reduces module-to-module traffic and corresponding increases the transmit bandwidth of a module.

摘要： A system with at least one, and preferably at least two, end devices that operates according to a point-to-point protocol such as the IEEE standard 802.3ad. The two end devices communicate with each other through a trunk cluster formed from a plurality of cluster devices. Each of the cluster devices has a synchronization means for configuring all of the cluster devices with a same logical identity to communicate with the end device according to the point-to-point protocol as if all of the cluster devices were a single device.

摘要： An apparatus for and method of encapsulating Ethernet frame data in HDLC frames for transmission over a VDSL transport facility. The HDLC frames are transmitted over a point to point VDSL link where they are subsequently extracted and forwarded as standard Ethernet frames. The VDSL facility transport system comprises one or more Ethernet to VDSL CPEs coupled to a DSLAM over a VDSL transport facility. The Ethernet to VDSL CPE functions to receive a 10BaseT Ethernet signal and encapsulate the Ethernet frame into a HDLC frame for transmission over the VDSL facility. In one embodiment, a single chip microcontroller on the CPE performs both Ethernet controller and HDLC controller functions. The DSLAM is adapted to receive HDLC frames from one or more CPEs, extract Ethernet frames therefrom and generate and output a standard Ethernet signal. Ethernet frames are encapsulated within HDLC frames and transmitted on the wire pair without regard to the state of the SOC signals. This overcomes the problems associated with synchronizing the transmission of the Ethernet data with the SOC signals.

摘要： A method for allocating network addresses comprises providing an address pool comprising a plurality of network addresses and then dividing the address pool into a plurality of address sub-pool that comprise a unique subset of the network addresses of the address pool. Each of the sub-pools is available for use by any one of a plurality of routing devices of a network access server. The method then comprises receiving a request to assign a first network address to a first user, allocating a first address sub-pool of the plurality of address sub-pools to a first routing device of the plurality of routing devices and transmitting a first message to the other routing devices to indicate that the first address sub-pool has been allocated. The method additionally comprises assigning the first network address to the first user from the first address sub-pool and advertising an aggregate route for the first address sub-pool over a network.

摘要： A system and method is provided for transferring packet-switched data across a network. A network interface may be connected to a primary switch and a secondary switch, both of which may be connected to a network. The network interface may also convert between circuit-switched data and packet-switched data. Further, packet-switched data may be transferred between the network interface and the network across the primary switch if the primary switch is operable, and across the secondary switch if the primary switch is inoperable. The system and method may also include a selection switch, route server and controller. Additionally, the system and method may include a primary router and a secondary router. Packet-switched data may be transferred across the primary router if the primary router is operable, and across the secondary router if the primary router is inoperable.
