摘要： An access router of a local mobile network includes a delegation resource for delegating address prefixes and a routing resource configured for parsing reverse routing headers from received data packets. The delegation resource supplies each mobile router attaching to the local mobile network with a corresponding unique delegated address prefix within an available network prefix for use within the local mobile network. Each mobile router attached to the access router via another mobile router utilizes a reverse routing header to establish a tunnel with the access router, enabling the access router to source route messages to the mobile router via its corresponding local care-of address and next-hop addresses specified in the reverse routing header. Each mobile router creates a remote care-of address based on the delegated address prefix, minimizing the need for binding updates with the corresponding home agent as the mobile router moves within the local mobile network.

摘要： Methods and devices are provided for identifying end devices and automatically configuring associated network settings. Preferred implementations of the invention do not require users to manually identify connection types (e.g., RFID, IPphone, manufacturing device, etc.) or to manually configure the network device. Accordingly, such implementations allow automatic switch configuration, even for devices that use inconsistent protocols and/or protocols that are not well known. Some methods of the invention employ DHCP options combined with traffic snooping to identify devices and automatically apply appropriate switch port configuration.

摘要： An improved technique for processing a DHCP request from a DHCP client device is performed in a data communications device of a network (e.g., performed in a router). The technique involves receiving the DHCP request from the DHCP client device, evaluating a set of rules in response to the DHCP request to obtain a rule-based classification result, and outputting a DHCP response in response to the rule-based classification result. In some arrangements, a policy manager which is external to the data communications device plays a role in the classification process (e.g., dynamic updating of the set of rules, responding to individual queries from the data communications device when generating the rule-based classification result, etc.). Such improvements over conventional DHCP approaches enables improved flexibility and coordination of the DHCP process.

摘要： A technique controls operation of a BRAS device. The technique involves extracting encapsulation information from a communications exchange between a CPE device and an external server device (e.g., a DHCP server). The communications exchange passes through the BRAS device and a DSLAM device. The technique further involves storing the encapsulation information in local memory of the BRAS device, and controlling a flow of a downstream communication passing through the BRAS device and the DSLAM device toward the CPE device based on the encapsulation information stored in the local memory of the BRAS device. Accordingly, the BRAS device is well suited for performing ATM overhead accounting as well as shaping and policing downstream traffic.

摘要： A method and apparatus for registering auto-configured network addresses includes receiving first data at a networking device connected to a host at a physical connection. The first data is received from a first server and indicates authentication information associated with the host. A first message is received at the networking device from the host. The first message requests configuration information and includes a logical network address for the host determined at least in part by the host. A second message is generated based on the first message and the first data. The second message is sent to a second server that registers the host by associating the logical network address with the first data.

摘要： Disclosed are, inter alia, methods, apparatus, computer-storage media, mechanisms, and means associated with loss of network layer connectivity triggering Dynamic Host Configuration Protocol (DHCP) initialization. According to one embodiment, a network device connected to a network initializes one or more network communication values of the network device using DHCP. The network device monitors Network Layer (Layer 3) connectivity with a remote network device; and in response to detecting a loss of said monitored Network Layer connectivity, DHCP initialization of the network device is performed.

摘要： Techniques for assigning a network address to a host are based on authentication for a connection between the host and an intermediate device. One approach involves receiving first data at the intermediate device from an authentication and authorization server in response to a request for authentication for the connection. The first data indicates at least some of authentication and authorization information. A configuration request message from the host is also received at the intermediate device. A second message is generated based on the configuration request message and the first data and is sent to a configuration server that provides the logical network address for the host. The configuration server provides the logical network address based on authorization and authentication information. The logical network address is thus based on the user, e.g., to limit access by the user to the Internet and other services.

摘要： Methods and devices are provided for locating, identifying and provisioning devices in a network. According to some implementations of the invention, a combination of EPC code information and existing networking standards form the basis of identifying and provisioning methods. For example, first location information included in a DHCPDISCOVER request can be used to determine appropriate configurations for networked devices. In some such implementations, the first location information is read from an RFID tag near the networked device and is inserted in the DHCPDISCOVER request. The first location information may include any type of absolute or relative coordinate, positioning, cartographic or similar information and/or information from which such information may be derived. Second location information, which may be a logical name, is provided to the device. If the device is an RFID reader, the second location information may be included with reads from RFID tags that are transmitted from the RFID reader.

摘要： During one mode of operation, a configuration server receives a signal to modify configuration information associated with a given host computer. To prompt reconfiguration of the given host computer, the configuration server generates a reconfiguration command to the given host computer. A network interface (through which the given host computer accesses a network) intercepts the reconfigure command and terminates a communication link through which the given host computer communicates to access the network. Termination of the communication link prompts the given host computer to initiate a reconfiguration routine for assignment of a new network address. Alternatively, the network interface forwards the reconfigure message to the given host computer and monitors communications from the given host computer to determine whether it executes the reconfigure command. If not, the network interface terminates a communication link prompting the given host computer to initiate a reconfiguration routine for assignment of a new network address.
