摘要:
A method of implementing a cloud computing network includes defining, for a cloud computing network including tangible network storage elements and tangible network computing elements, a library of network connectivity building blocks for designing a virtual private cloud computing network within the cloud computing network. Each building block has user-definable attributes and each building block is translatable into a set of network element configuration statements that instantiate an action particular to the building block. Usage rules specifying how the building blocks can be used are defined for the cloud computing network. Dynamically-selected building blocks from the library are accepted and assembled into a configuration template. The configuration template is validated against the usage rules. The virtual private cloud computing network is implemented in accordance with the validated configuration template.

The invention provides a portable customizable desktop environment, enabling a User to replicate and use the User's preferred desktop configuration on any computing device by means of an enabled portable memory device such as USB drive. Further, the portable desktop can be encapsulated, such that little if any trace of the use of the portable desktop are glean-able from the host computer. Also provided is a method of learning to duplicate a program's environment requirements within the portable desktop environment. The invention further provides a means for providing universal synchronization of a portable customized desktop, thereby preserving data and providing alternate access by User.
摘要:
The invention comprises a method and apparatus for managing route selection in a network. Specifically, the method comprises receiving a set of routes from each of a plurality of routers, filtering each of the sets of routes, and selecting at least one route from each of the filtered sets of routes according to routing information associated with each of the respective routers.

Methods, apparatus, and articles of manufacture to provide a multicast virtual private network (MVPN) are disclosed. An example method includes sending a multicast receiver route received from one of a multicast service processor or a provider edge router to another of the multicast service processor or the provider edge router, wherein the multicast service processor is communicatively coupled to the provider edge router via a multicast control plane topology that is non-congruent to a unicast control plane topology, and replicating multicast data received from the other of the multicast service processor or the provider edge router to the one of the provider edge router or the multicast service processor based on the multicast receiver route.
摘要:
A network routing and service control design enables an internet protocol (“IP”) network to effectively divert, on-demand, a given set of IP traffic flow from its normally followed network path to a network-attached application service processing complex and then enable the IP network to re-inject post-processed (e.g., Distributed Denial of Service scrubbed) traffic back into the network for routing to an originally-intended destination. This design also provides a sophisticated control mechanism for application service providers and/or customers/users for service management purposes. For example, application service providers can manage network and service processing resources and customers/users can manage their service requests.

摘要:
A network that supports VPNs is enhanced to allow users in one VPN to communicate with users in another VPN in the course of executing a predefined application, such as VoIP. This capability is achieved dynamically by enabling a device that can communicate with the network elements that operate to normally prohibit inter-VPN communication to direct those network elements to enable such communication, at least for the purposes the purposes of specific applications.
摘要:
A method and apparatus are disclosed for dynamically reducing clock skew among various nodes on an integrated circuit. The disclosed clock skew reduction technique dynamically estimates the clock delay to each node and inserts a corresponding delay for each node such that the clock signals arriving at each node are all in phase with a global clock (or 180° out of phase). Delays attributable to both the wire RC delays and the clock buffer delays are addressed. A feedback path for the clock signal associated with each node allows the round trip travel time of the clock signal to be estimated. When the length of the feedback path matches the length of the primary clock path, the clock skew present at the corresponding node can be estimated as fifty percent (50%) of the round trip delay time. Dynamic adjustments to the delay control circuit are permitted as operating conditions shift. Clock signals arriving at individual nodes on the integrated circuit remain in phase with the global PLL clock (PCK), regardless of variations in the operating voltage or temperature (or both).
摘要:
A method and apparatus for providing traffic management for distributed denial of service (DDOS) traffic. Within a communications network, a DDOS detection system monitors network traffic to identify traffic that is designed to attack a particular server within the network and their entry points into the network. A traffic routing control unit is requested to deny service to the DDOS traffic. By selectively manipulating the routing information propagated to network edge routers, the traffic that is denied service is limited to mostly DDOS traffic and is routed to a cleaning center or a null address in the most effective fashion.
