....Debugging routing problems. With provider provisioned VPNs, the customer and provider share the job of maintaining a network and debugging routing and connectivity problems. For example, the maintenance of disjointness is generally considered the customer s task (see for example [5] [15]) However, new debugging tools may be needed to coordinate debugging between customers and providers, and between multiple providers supporting the same VPN. For example, consider a violation of condition (b) of disjointness that might arise when an administrator dynamically announces a new ....
....reply with permission to do so. SLA assurance. VPN customers may expect strict adherence to Service Level Agreements (SLAs) that commit a provider to maintaining specified levels of performance such as uptime, available bandwidth, limits on packet loss and delay (for more examples, see [15]) Designing and deploying networks with predicatable performance guarantees is a very difficult problem. VPNs make this even more difficult due to the potentially diverse requirements imposed by a large heterogeneous customer base. For example, the management of intra PE tunnels is greatly ....
