A transit signal corresponding to the original signal and including at least the embedded destination service address is routed through the network to an egress capable network device of the network according to the internal routing address. The transit signal enables the egress capable network device to restore the embedded destination service address and to forward the transit signal from the network. | 2010-04-22 |
20100098085 | METHOD, SYSTEM, AND DEVICE FOR IMPLEMENTING ACTIVE/STANDBY SWITCHOVER - A method for implementing an active/standby switchover includes: sending received data to an active device corresponding to a physical IP address in a mapping relation with a preset communication identification (ID); changing the physical IP address of the active device in the mapping relation with the communication ID to the physical IP address of a standby device for switchover when determining that the system needs to perform the active/standby switchover; sending the received data to the standby device corresponding to the physical IP address in the mapping relation with the preset communication ID after the system performs the active/standby switchover. A system and device for implementing an active/standby switchover are also disclosed. With the method, system, and device provided by the present invention, a long interruption of ongoing services is prevented when the active/standby switchover is performed. | 2010-04-22 |
20100098086 | Preventing Forwarding of a Packet to a Control Plane - This invention includes tools that prevent forwarding of a packet to a control plane of a packet switch. The tools receive a packet comprising indicia suggesting that the packet be forwarded to a control plane of a packet switch. After receiving the packet, the tools may modify the packet to prevent the packet from being forwarded to the control plane, intercept the packet before it is received by the control plane, or otherwise prevent the packet from being forwarded to the control plane. The tools may also forward the packet from a source port of a packet switch to a destination port of the packet switch without forwarding the packet to the control plane of the packet switch. | 2010-04-22 |
20100098087 | Traffic Generator Using Parallel Coherent Transmit Engines - There is disclosed a packet generator and method of generating a packet flow. The packet generator may include a plurality of parallel transmit engines to form packets for transmission and a multiplexer to coherently interleave packets formed by the plurality of transmit engines. | 2010-04-22 |
20100098088 | Pseudo Wire Establishing Method and Device - For precluding useless resources of a pseudo wire in a device distributing pseudo wires to lighten the receiving capacity, MPLS (Multi Protocol Label Switching) tunnels are established with an opposing device. From among the established MPLS tunnels, an MPLS tunnel having a remaining resource for a pseudo wire at interfaces having the MPLS tunnels in response to a pseudo wire establishment request is selected and the information of the selected MPLS tunnel associated with a label of the pseudo wire having the remaining resource is distributed to the opposing device. Alternatively after having established the MPLS tunnels with the opposing device, when a distribution request of the pseudo wire information associated with desired MPLS tunnels is received from the opposing device having received the pseudo sire establishment request, a label of the pseudo wire is similarly determined and distributed to the opposing device together with the information of the MPLS tunnel passing the pseudo wire. | 2010-04-22 |
