Title: "Mutable Services: Technology for Building Resilient Network
Infrastructures"

Abstract:
End-user experience while accessing network services in a shared wide-area 
network environment such as the Internet is influenced by several factors 
including the latency and bandwidth seen by individual requests, and the 
degree to which these requests affect each other. Therefore, it is 
difficult to ensure predictable service availability in the face of either 
benign or malicious network and client load conditions. These problems are 
difficult to overcome given the static nature of routes and the monolithic 
nature of services in current-day systems. The Mutable Services 
infrastructure addresses these problems by articulating a different view, 
one which sees services as being flexibly constructed from distributed 
components that can on-demand be deployed closer to the network edge. By 
replicating and migrating appropriate components and controlling how 
requests are routed to them, the infrastructure can cope with a variety of 
anomalous network and client load situations. This talk will describe early 
progress with building the Mutable Services infrastructure, focusing on the 
construction of a J2EE-based service distribution framework, and an 
IP-level architecture for managing client requests to provide 
differentiated service.
