Prem Gopalan will present his research seminar/general exam on Wednesday 

May 4 at 9:30 AM in Room 302.  The members of his committee are: Mike 

Freedman (advisor), Jen Rexford, and Margaret Martonosi.  Everyone is 

invited to attend his talk, and those faculty wishing to remain for the oral 

exam following are welcome to do so.  His abstract and reading list follow 






Historically, Internet services provided clients with access to the             

resources of a particular host. However, today's services are no                

longer defined by a single host or confined to a fixed location. Yet,           

the network architecture continues to impose a coupling between hosts           

and services by binding connections to topology-dependent addresses,            

rather than topology-independent service names -- complicating                  

everything from server replication, load balancing, and                         

virtual-machine migration, to client mobility and multi-homing.  We             

propose a new service access layer that redefines the interaction               

between the network and transport layers. This layer provides the               

"thin waist" needed to enable direct communication on service names,            

decouple service connections from network identifiers, and enhance the          

network's awareness of service availability.                                    


In this talk, we focus on how to rearchitect today's end-host network           

stack to include the service access layer while maintaining backwards           

compatibility with today's IP networks and requiring minimal changes            

to applications. We present the design of transport protocols running           

in this framework, and evaluate our Linux implementation.
