摘要： The present invention provides a method and apparatus for obtaining addresses for multiple interfaces in a device. The method comprises generating a message and transmitting the message to a server over a communication link. The message includes a request for a server to provide a first address to assign to a first interface of a client device and a second address to assign to a second interface of the client device. The method further comprises receiving a response from the server configuring at least one of the first interface and second interface based on the response received from the server. The response includes the first address and the second address.

摘要： A method, data processing system, and computer usable code are provided for protocol definition for software bridge failover. In a first aspect of the present invention, a first software bridge determines the proper working operation of a physical adapter. Limbo packets are sent to a second software bridge alerting the second software bridge that the first software bridge is no longer bridging traffic responsive to the physical adapter failure in the first software bridge. The second software bridge receives the limbo packets, and, in response to receiving the limbo packets, asserts primary control and initiates bridging of traffic. In an alternative aspect of the present invention a first software bridge sends keep-alive packets. A second software bridge monitors the keep-alive packets from the first software bridge and, in response to a failure to detect the keep-alive packets from the first software bridge, the second software bridge initiates bridging of traffic.

摘要： Methods, systems, and products are provided for tunneling IPv6 packets. Embodiments include receiving, by an origin IPv6 border router from an origin IPv6 host, an IPv6 packet having an IPv6 destination address; receiving, by an origin IPv6 border router from an origin IPv6 host, an IPv4 address for a destination IPv6 border router retrieved from a data structure associating IPv6 destination addresses with IPv4 addresses for destination IPv6 border routers; encapsulating, by the origin IPv6 border router, the IPv6 packet in an IPv4 packet; and sending the encapsulated packet to a destination IPv6 border router at the IPv4 address. In many embodiments, encapsulating, by the origin IPv6 border router, the IPv6 packet in an IPv4 packet is carried out by adding an IPv4 header to the IPv6 packet.

摘要： A system and method for allocating resources on a network, including a server and at least one client. The resources are associated within a single set, such that the number of resources within the network can be easily incremented or decremented. Flags are associated with each resource, where the flags may be set to one of two states: a first state or a second state. When the server receives a connection request from a client, the server examines the flags associated with the resources to find a flag set to a second state. Upon finding a resource with a flag set to the second state, that resource is assigned to the client. Once the resource is assigned to a client, the associated flag is set to a first state and another flag associated with another resource is set to a second state.

摘要： The invention relates to a router that keeps a short-lived cache of DHCP packets. Each time the router receives a DHCP request or discover packet, the router checks to see if the packet is already in the cache. If the packet is in the cache and has already been processed, the router will discard or ignore the duplicate packet.

摘要： A method, apparatus, and computer instructions for managing network addresses. A received network address from a current server is compared for use in identifying the data processing system with a prior network address from a previous server. A release data packet is created if the received network address is a new network address and the previous server is a different server than the current server in which the release data packet includes the prior network address. The release data packet is sent to the previous server in which the release data packet causes the previous server to release the prior network address for reuse.

摘要： A computer implemented method, apparatus, and computer usable program code for configuring a remote data processing system. A configuration is identified for the remote data processing system to form an identified configuration. The hardware for the remote data processing system is configured. An installation application is sent to the remote data processing system across a communications link after the hardware in the remote data processing system has been configured, wherein the installation application executes on the remote data processing system to configure the remote data processing system. Installation files are sent across the communications link to the installation application executing on the remote data processing system. The installation program uses the installation files to configure install a set of operating systems, install applications, and configure software on the remote data processing system.

摘要： A resolver queries a DNS server for any network addresses associated with the particular domain name. If the resolver detects a response for the DNS server with multiple network addresses for a particular domain name, then the resolver creates and sends a shortest path query to at least one router enabled to receive and respond to shortest path queries. The shortest path query indicates at least one source address and the multiple destination addresses returned by the DNS server for the particular domain name. The router detects a separate length for each path accessible between each source address and each of the multiple destination addresses. The router then orders the destination addresses from shortest path to longest path and returns the ordered destination addresses to the requesting resolver. The resolver caches the ordered network addresses in the local cache in association with the particular domain name, such that for future requests for the particular domain name, the resolver retrieves from local cache the shortest path network address as ordered by the router. In addition, the resolver, responsive to receiving the ordered destination addresses, selects the shortest path network address for a response to an application requesting the resolution of the particular domain name.
