摘要： A system for assisting in controlling real-time transport protocol flow through multiple networks is disclosed. The system utilizes at least a first computer and a second computer that is connected to the first computer, wherein the second computer comprises a second transceiver, a second memory having logic stored therein defining functions to be performed by the second computer, and a second processor. The second processor is configured by the second memory to perform the functions of: performing an inbound screen on route information received by the second computer, from the first computer, to determine if the received route information should be discarded; if the route information is not discarded, comparing the received and screened route information to a local policy defined with the second computer, and performing an outbound screen on the received and screened information prior to transmitting the received and screened information.

摘要： A system and method for assisting in controlling real-time transport protocol flow through multiple networks via media flow routing is disclosed. The system utilizes a first computer and a second computer connected to the first computer, via a group of associated computers, wherein each of the first computer, second computer, and group of associated computers comprise a transceiver, a memory, and a processor. The processor is configured by the memory to perform the functions of: performing an inbound screen on route information received from the first computer, to determine if the received route information should be discarded; if the route information is not discarded, comparing the received and screened route information to a local policy defined within the second computer; performing an outbound screen on the received and screened information prior to transmitting the received and screened route information to the first computer; and selecting a primary route from the received route information and local route information in accordance with the local policy, wherein the primary route is a path from the second computer to the first computer via the group of associated computers.

摘要： A system for assisting in controlling real-time transport protocol flow through multiple networks via use of a cluster of session routers is disclosed. The system utilizes a first computer and a cluster of computers, wherein the cluster of computers comprises at least two associated computers that are connected to the first computer. Each of the associated computers comprises a second transceiver, a second memory having logic stored therein defining functions to be performed by the associated computers, and a second processor. The second processor is configured by the second memory to perform the functions of: performing an inbound screen on route information received by an associated computer, from the first computer, to determine if the received route information should be discarded; if the route information is not discarded, comparing the received and screened route information to a local policy defined within the cluster of computers; and performing an outbound screen on the received and screened information prior to transmitting the received and screened information outside the cluster of computers.

摘要： A system for assisting in controlling real-time transport protocol flow through multiple networks via screening is disclosed. The system utilizes a transceiver, a memory having logic stored therein defining functions to be performed by the system, and a processor. The processor is configured by the memory to perform the functions of: determining if route information received by the transceiver is from an external source or an internal source; if the route information is from an external source, performing a first internal screen of the route information, wherein a destination address defined by the received route information is compared to a local destination address defined by the first internal screen; and if the route information is from an internal source, performing a second internal screen of the route information, wherein an origin address defined by the received route information is compared to a local origin address defined by the second internal screen.

摘要： Systems and methods for redundancy in a network device are disclosed. An exemplary device comprises: a controller residing on a data forwarding element (DFE), the DFE performing data forwarding operations; and a first and a second control processor. Each of the control processors has either an active role or a standby role with respect to the DFE controller. The active-role control processor communicates with the DFE to configure the DFE forwarding operations and receives at least some communications from the DFE controller over a virtual channel. The DFE controller directs traffic on the virtual channel that is destined for the active-role control processor to either the first or the second control processor based on which of the control processors currently has the active role.
