Observations Observations

OPENSIG and active networks

Can you characterize programmable networks– Networking technology– Degree of programmability– Programmable communications abstractions– Programming methodology– Architectural domain

Common ground– making networks more programmable – Enabling technology

Is there a VN Technology Gap?Is there a VN Technology Gap?

State-of-the-art– How do I setup a VN in the same time it takes to open a

socket/bind or RPC?

– What is the middleware glue to do this?

Where are we today in the field?– TEMPEST, NETSCRIPT and X-Bone

Genesis – The middleware: a virtual network operating system?

– Profiling, spawning, managing, architecting
