Possible definitions of Programmable Networks
Ability to to dynamically allocate and reconfigure network resources in
response to customer demand for adds, moves and changes, to reallocate
network resources in response to breakdowns or traffic bottlenecks. Other
uses are load balancing and location based resource allocation in Cloud
based services including so called ‘Cloud phones’.
Layer 2 and layer 3 VPN’s respond to this definition. VLAN’s, MPLS, Ethernet
services, CDN’s, VoIP networks, sensor networks, SaaS, IaaS, virtualization
…
 setting up a temporary lambda on GLIF between Triumf in Canada and CERN
in Geneva over Canarie and Netherlight also falls in this category

Some non trivial Middleware issues
Reliability ? Security ? Interoperabity ? End to end service guarantees and
QoS ? Open or proprietary software platforms?
Off-net access, multiple layers of encapsulation and tunneling.
Deterministic or Best Effort or hybrid ?
Internetworking, Network to Network Interfaces (NNI’s), service quality and
service management expectations.

Some desirable R&E initiatives in the Programmable Network Space
 Increase support of GLIF efforts on Lambda switching middleware.
 Support of Grid efforts to facilitate the storage and handling of very large
geographically distributed data sets for physics, astronomy, genomics,
seismology, etc. Ditto for distributed computing. IPv6 is self evident
 Optimization of location based access to distributed data sets and
computing facilities for a cloud phone.
 Workable Middleware for high quality video conferencing across network
boundaries.
 Going to Mars: Delay Tolerant Programmable Networks?
