Replicating IP Services

چکیده
With the explosive growth of demand for services on the Internet, the networking infrastructure (routers, protocols, servers) is under considerable stress. Mechanisms are needed for current and future IP services to scale in a client-transparent way. We present HydraNet, an infrastructure that allows to dynamically distribute IP services by placing service agents (caching agents, mirrors, replicas) that are under the server's control at strategic points in the internetwork. HydraNet is based on replicating transport-level service access points (TSAPs) for transparent distribution or replication of IP services. Measurements on a local testbed show that the overhead of our scheme is small. TSAP replication is widely applicable. We use HydraNet to implement active Web caching and highly fault-tolerant servers. Similarly, it can be used to implement application gateways, for example intelligent multicast re ectors for media-on-demand.

متن کاملA Client Oriented, IP Level Redirection Mechanism
This paper introduces a new approach for implementing transparent client access to network services. Ever increasing load on the Internet has made it essential to design services that are fast, reliable, easily manageable, transparent to access, and that can scale gracefully with load. A common way of achieving this has been replicating services across multiple servers and redirecting clients t...
متن کاملEngineering Fault-Tolerant TCP/IP Servers Using FT-TCP
In a recent paper [2] we have proposed FT-TCP: an architecture that allows a replicated service to survive crashes without breaking its TCP connections. FT-TCP is attractive in principle because it does not require modifications to the TCP protocol and does not affect any of the software running on the clients; however, its practicality for realworld applications remains to be proven. In this p...
متن کاملImprove Replica Placement in Content Distribution Networks with Hybrid Technique
The increased using of the Internet and its accelerated growth leads to reduced network bandwidth and the capacity of servers; therefore, the quality of Internet services is unacceptable for users while the efficient and effective delivery of content on the web has an important role to play in improving performance. Content distribution networks were introduced to address this issue. Replicatin...
