摘要:
A mobile node includes a processor, a network interface, and a storage device having computer program code for execution by the processor. The computer program code includes a network layer for transmitting and receiving packets and an intermediate driver that transmits packets to the network layer and receives packets from the network layer using a virtual internet protocol (IP) address to identify the mobile node. The intermediate driver transmits packets to the network interface and receives packets from the network interface using a routable actual IP address to identify the mobile node. The intermediate driver permits the actual IP address to change when the mobile node moves from a first subnet to a second subnet without a corresponding change in the virtual IP address. A corresponding NAT associates the virtual IP address with a second actual IP address when the NAT is notified that the mobile node is in the second subnet.

Overload conditions affecting a processor of a network switch or the like are substantially eliminated, and the processing of traffic is gradually allowed to increase, by inserting, and then monitoring one or more probes which are placed into a queue of the processor. During a given measurement interval, if the number of probes exceeds a threshold then an overload condition exists. This condition is subsequently reduced using “multiplicative decrease” techniques. Conversely, if the threshold is not exceeded and there is little or no chance an overload condition can quickly reappear, traffic is allowed to once again be processed gradually using “additive increase” techniques.

In general, a capability for forwarding packets based on path encoding is presented. The capability for forwarding a packet based on path encoding may be configured to enable forwarding of a packet along a network path by determining a path encoding label for the network path, associating the path encoding label for the network path with the packet, and forwarding the packet along the network path based on the path encoding label associated with the packet. The network path for a packet may include an ordered sequence of node output interfaces of an ordered sequence of nodes. The path encoding label for the network path includes an ordered sequence of node interface labels corresponding to the ordered sequence of node output interfaces of the nodes of the network path. The nodes of the network path forward the packet along the network path based on the path encoding label.

The present invention provides a sagacious routing engine for use with a session initiation protocol (SIP) call. In one embodiment, the sagacious routing engine includes a request manager configured to receive a routing request for an integrated routing target set for the SIP call within a network. Additionally, the sagacious routing engine also includes a route manager, coupled to the request manager, configured to employ a dynamic routing table for the routing request to provide the integrated routing target set to the request manager for routing the SIP call within the network.

A managed Universal Serial Bus (USB) service capability is disclosed. The managed USB service capability is configured to use a mobile computing device (e.g., a smartphone or other suitable mobile computing device) to support a set of services for a computer (e.g., a desktop, a laptop, and the like) capable of connecting to the mobile computing device via a USB connection. The managed USB service capability enables local and/or remote control of the mobile computing device to operate in various USB device classes, such that the mobile computing device can provide various managed USB services for the computer via the peripheral connection. In this manner, the mobile computing device may be dynamically configured to operate as one or more of a network interface, a virtual private network (VPN) client, a smart card, a serial console, a mass-storage device, a booting device, and the like.

A resource assignment capability is presented. A resource specification associated with a plurality of elements is received. The resource specification includes, for each of the elements, a resource request including an indication of a quantity of resources requested by the element and a resource offer including an indication of a quantity of resources offered by the element for use by one or more other elements. A resource assignment, including an indication of an association between the resources requests and the resource offers, is determined using a resource assignment process. The resource assignment process may be a greedy assignment process or a maximum flow resource assignment process. The maximum flow resource assignment process includes constructing a maximum flow resource graph based on the one or more resource specifications and applying a maximum flow process to the maximum flow resource graph to determine thereby the resource assignment.

An exemplary cloud computing apparatus includes at least one compute device controller. A digital data storage of the controller includes a chief management virtual machine program for running a chief management virtual machine. A processor associated with the digital data storage is configured to run the chief management virtual machine. The chief management virtual machine is useful to control first user communications between at least one first user and a first virtual machine and to control second user communications between at least one second user and a second virtual machine. The first virtual machine and the second virtual machine are run by at least one compute resource distinct from the compute device controller. The chief management virtual machine is also useful for isolating the first user communications from the second user communications.
