摘要： PURPOSE: To extend a remote interface to a 2nd network in a transparent way by providing a network service to a data frame of 1st and 2nd networks through a local interface and the remote interface. CONSTITUTION: A border router 12 is provided with a local interface that service a service to a local LAN 9, and the LAN 9 provides an access to a network resource in the border router to an end system of the LAN 9. The border router 12 interfaces similarly other local LAN and includes a remote routing interface 17. The remote routing interface 17 provides an interface to a network resource with respect to a plurality of end systems of a remote network 11. In order to support the remote routing interface 17, the order router stores an end system directory 18 to provide the service to a higher level protocol group of the remote network 11.

摘要： PROBLEM TO BE SOLVED: To provide the early initialization of transmission of data in a network interface that includes a dedicated transmit buffer in a system which includes logic for transferring frames of data composed by a host computer into the transmit buffer. SOLUTION: The amount of data of the frame which is downloaded by the host to the transmit buffer is monitored to make a threshold determination of an amount of data of the frame resident in the transmit data buffer (34). A network interface controller includes logic (36) for initiating transmission of the frame when the threshold determination indicates that a majority of the frame is resident in the transmit buffer, and prior to transfer of all of the data of the frame buffer (34) into the transmit buffer. The monitoring logic includes a storage device (43), which is programmable for storing a threshold value. Thus, the threshold value may be set by a host system to optimize performance.

摘要： PROBLEM TO BE SOLVED: To overcome a problem that packet service node selected randomly in a mobile network. SOLUTION: In response to detection of a mobile client within a service area of a wireless node, a registration request is sent from the wireless node to a control node. When receiving the request from the wireless node, the control node determines an external agent for providing communication services to the mobile client based on mobile client information records, wireless node records, and a plurality of external agent records associated with the wireless node, and can select a final service external agent associated with the mobile client. If selecting an external agent different from the final service external agent, the control node sends a registration renewal message to the final external agent for providing services, so that a communication session can be finished.

摘要： PROBLEM TO BE SOLVED: To provide a system and method for transmitting information between a mobile node and the home agent of the mobile node. SOLUTION: A mobile node is connected to an HAAA server. The address of the HAAA sever is decided. Information, indicating a method for connecting the mobile node to the HAAA server and for deciding the address of the home agent of the mobile node, is received. A proxy sever determines the address of the home agent, by using the information received from a PDSN. Then, information is transmitted from the mobile node to the home agent by using the address.

摘要： PURPOSE: To provide an adaptor parallelly operating with another process without an excessive load in a client computer in a LAN system. CONSTITUTION: A DMA ring buffer is provided for receiving PIO to copy a packet directly to the memory of a host when FIFO buffer 190 is full. In order to reduce a delay time, an adapter 10 can be programmed to generate an early receiving interruption at the time of receiving only a part of the packet and to generate a second early interruption signal so that the copy of the packet to the host may be overlapped with the last reception of the packet. At the time of starting packet transmission before the transmission completion of the packet to the adapter 10 from the host, the delaying time is reduced more. As the delay time is minimized, receiving/transmitting FIFO buffers 170 and 190 which are small enough to be included within RAM of ASIC 210 including the other circuits 110, 130, 140, 200, etc., can be used.

摘要： A mobile node may roam away from its home network to a foreign network. The mobile node may communicate using the Mpbile Internet Protocol, and it may use Internet Protocol security to communicate with its home network. A foreign agent on the foreign network and a home agent on the home network may dynamically link a policy to be used for a Internet Protocol security session between the foreign agent and the home agent. The foreign agent and the home agent may dynamically create a filter to be used for the Internet Protocol Security session.

摘要： A system and method for determining a MAC layer address of a network interface on a remote device, based on an IP address associated with the same network interface on the remote device. The disclosed system identifies an internetworking device, for example a router, that is attached to the remote subnet to which the network interface of the remote device is attached. The system identifies the network interface of the router that is attached to the remote subnet, and obtains the MAC address of that network interface from an address resolution protocol (ARP) cache associated with it. The system transmits a series of request packets having an IP destination address equal to the provided IP address of the remote device, each including a time to live value, indicating a maximum number of network hops over which each particular packet may be forwarded. The time to live values of the request packets result in each successive request packet being forwarded one hop further along the path to the remote device. The internetworking devices along the route to the remote device each receive one request packet that cannot be forwarded because the time to live value has been decremented to zero. As a result, each internetworking device along the route returns a reply packet to the requesting device indicating its IP address.

摘要： A method of finding a mobile wireless communications device when an Internet Protocol (IP) packet from a remote user is sent to the device over an IP network. The mobile device does not have to register with the IP network in order to receive the IP. The method comprises the steps of receiving the IP packet at a home agent associated with a wireless communications network. The IP packet includes an IP address assigned to the device. If there is no current mobility binding record for the mobile device, instead of dropping the packet the home agent sends an access-request packet, containing the IP address, to an authentication server. The authentication server, e.g., a RADIUS server, maintains a table mapping the IP address for the device to an identification number uniquely associated with the device, such as the device's International Mobile Subscriber Identity number. The authentication server sends an access-accept packet to the home agent in the event that the device is authorized to receive the IP packet, in which case the access-accept packet includes the identification information. The home agent uses the identification number to locate, page and automatically connect the wireless device to the IP network via an InterWorking Unit (IWU) configured as a IP network access server.
