Abstract
Methods, computer-readable media and computing systems are provided for analyzing service impacts on one or more VPNs on a computer network. A topology of each VPN may be identified. A protocol failure may be detected between routers of the computer network. It may then be determined how the VPN is affected by the protocol failure based on the identified topology and VRF information obtained from routers of the computer network.
Claims20
A method of analyzing service impact on a VPN due to protocol failure on a computer network, comprising:
- identifying a topology of the VPN;
- detecting a protocol failure between routers of the computer network;
- and
- determining how the VPN is affected by the protocol failure based on the identified topology and VRF information obtained from routers of the computer network.
A computer-readable storage medium having computer-executable instructions for analyzing service impact on VPNs, the instructions causing a computer to perform steps comprising:
- detecting a protocol failure between routers of a computer network;
- identifying a VPN that is affected by the protocol failure;
- and
- determining whether the VPN will experience performance degradation or lost of connectivity based on a topology of the VPN.
A computing system for analyzing service impact on a VPN due to protocol failure on a computer network, comprising:
- a processor;
- and
- memory containing instructions for causing the processor to:
- identify a topology of the VPN;
- identify a first router as being inoperative where the first router is a BGP peer of a second router that has experienced a change from a higher state to a lower state in its BGP finite state machine;
- and
- determine how the VPN is affected by the inoperability of the first router based on the identified topology.
