Serval: An End-Host Stack for Service-Centric Networking

Free registration required

Executive Summary

Internet services run on multiple servers in different locations, serving clients that are often mobile and multi-homed. This does not match well with today's network stack, designed for communication between fixed hosts with topology-dependent addresses. As a result, online service providers resort to clumsy and management intensive work-arounds - forfeiting the scalability of hierarchical addressing to support virtual server migration, directing all client traffic through dedicated load balancers, restarting connections when hosts move, and so on.
