Abstract
A management system manages multiple multi-protocol label switching (MPLS) virtual private networks (VPNs), the VPNs having overlapping IP addresses. The system includes a storage storing a file that associates a host name with an IP address and a route distinguisher. The host name corresponds to a network element within one of the customer VPNs. The system also includes a label obtaining system that obtains at least one label for the host name based upon the associated IP address and route distinguisher. The system also has a packet construction system that creates packets destined for the network element using the obtained label(s).
Claims20
A management system for managing a plurality of customer multi-protocol label switching (MPLS) virtual private networks (VPNs), the VPNs having overlapping IP addresses, the system comprising:
- a storage unit storing a file that associates a host name, corresponding to a network element within one of the customer VPNs, with an IP address and a route distinguisher;
- a label obtaining system that obtains at least one label for the host name based upon the associated IP address and route distinguisher;
- and
- a packet construction system that creates packets destined for the network element using the obtained at least one label.
A computer readable medium storing a computer program for use when managing a plurality of customer multi-protocol label switching (MPLS) virtual private networks (VPNs), the VPNs having overlapping IP addresses, the medium comprising:
- a host file that associates a host name, corresponding to a network element within one of the customer VPNs, with an IP address and a route distinguisher.
A virtual private network (VPN) management method for managing a plurality of multi-protocol label switching (MPLS) VPNs, the VPNs having overlapping IP addresses, the method comprising:
- associating a host name, corresponding to a network element within one of the VPNs, with an IP address and a route distinguisher.
