1 Motivation Today's Internet services are commonly built over TCP (5), the standard Internet connection-oriented reliable transport protocol. The endpoint naming scheme of TCP, based on network layer (IP) addresses, creates an implicit binding between a service and the IP address of a server providing it, throughout the lifetime of a client connection. This makes a TCP client prone to all adverse conditions that may affect the server endpoint or the internetwork in between, after the connection is established: congestion or failure in the network, server overloaded, failed or under DoS attack. Studies that quantify the effects of network sta- bility and route availability (4, 2) demonstrate that connec- tivity failures can significantly impact Internet services. As a result, although highly available servers can be deployed, sustaining continuous service remains a problem. Service continuity can be defined as the uninterrupted de- livery of a service, from an end user's perspective. The TCP's ability to support it is limited by its error recovery scheme based on retransmissions to the same server end- point of the connection (bound to a specific IP address). In practice, the end user might be more interested in receiving continuous service rather than statically binding to a given server. As server identity becomes less important than the service, it is desirable for a client to switch servers during a service session, e.g., if a server cannot sustain the service. We propose the cooperative service model, in which a pool of similar servers, possibly geographically distributed across the Internet, cooperate in sustaining a service by mi- gration of client connections within the pool. The control traffic between servers, needed to support migrated connec- tions, can be carried either over the Internet or over a pri- vate network. From client's viewpoint, at any point during the lifetime of its service session, the remote endpoint of its connection may transparently migrate between servers. |
