Israel Cidon Ne X tworking’03 June 23-25,2003, Chania, Crete, Greece The First COST-IST(EU)-NSF(USA) Workshop on EXCHANGES & TRENDS IN N ETWORKING 1 Hardware signaling paradigm for resource reservation Israel Cidon Department of Electrical Engineering Technion

Israel Cidon Ne X tworking’03 June 23-25,2003, Chania, Crete, Greece The First COST-IST(EU)-NSF(USA) Workshop on EXCHANGES & TRENDS IN N ETWORKING 2 Short EE networking history Software packet switch – general purpose –Up to 1000s packets per second Routers built as parallel machines –Up to 10,000s packets per second Special hardware implementations –> 100,000,000 packets per second

Israel Cidon Ne X tworking’03 June 23-25,2003, Chania, Crete, Greece The First COST-IST(EU)-NSF(USA) Workshop on EXCHANGES & TRENDS IN N ETWORKING 3 Next generation services gaps Guaranteed, limited time p-t-p connection Large RT conferencing Video on demand - pay per view/listen Guaranteed large downloads RT Webcast Need user differentiation of valued vs. low significance traffic, not flow specs Gap in QoS support – not in raw throughput

Israel Cidon Ne X tworking’03 June 23-25,2003, Chania, Crete, Greece The First COST-IST(EU)-NSF(USA) Workshop on EXCHANGES & TRENDS IN N ETWORKING 4 Good old ways for QoS Support Reserve per connection for call duration –Requires massive signaling –Selection of available path –Statefull – soft-state increases CPU heat –More calls per second than ever imagined Practice – limit call demand to protect computation resources using aggregation

Israel Cidon Ne X tworking’03 June 23-25,2003, Chania, Crete, Greece The First COST-IST(EU)-NSF(USA) Workshop on EXCHANGES & TRENDS IN N ETWORKING 5 Modern QoS Support Over-provisioning –Cost, lack of differentiation, garbage dominates Network wide QoS classes –Coarse, lack of scalability, no real-time Signaling aggregation - MPLS LSPs or ATM VPs –Quasi-static, aggregated flows only (VPN) –Save signaling & routing CPU cycles - adds complexity Missing - user preference, instant billing… Depends on low value BW fillers Complex to understand and manage

Israel Cidon Ne X tworking’03 June 23-25,2003, Chania, Crete, Greece The First COST-IST(EU)-NSF(USA) Workshop on EXCHANGES & TRENDS IN N ETWORKING 6 Possible brute force solution? Hardware implementation of old model –Hardware generated signaling –Hardware assisted QoS routing Implementation cost optimization –Save complexity and space not CPU cycles Do we need hardware optimized architecture? –Not essential in ATM but help understanding problems How we deal with routing? –Source routing – caching, pre-computation –QoS based destination routing –Invest in accuracy or apply multiple path reservation

Israel Cidon Ne X tworking’03 June 23-25,2003, Chania, Crete, Greece The First COST-IST(EU)-NSF(USA) Workshop on EXCHANGES & TRENDS IN N ETWORKING 7 The KISS Architecture* Tailored around IP loose source routing –Support migration –Use route caching –Optimized for unicast Simple reservation, CAC and state structure –Random access –Soft-state protection * Joint work with Dan Gluskin

Israel Cidon Ne X tworking’03 June 23-25,2003, Chania, Crete, Greece The First COST-IST(EU)-NSF(USA) Workshop on EXCHANGES & TRENDS IN N ETWORKING Ways to grab this BW Hardware based signals further exploited –Fast multi-way reservation and release –Soft-state prevents resource locking –Relaxed accuracy and timely BW tracking Hardware supported QoS routing protocol –Side by side not extending current routing protocols –Use hardware - extensive messaging link-state –Hardware to assist with distance vector –Hardware to assist with path computation

Israel Cidon Ne X tworking’03 June 23-25,2003, Chania, Crete, Greece The First COST-IST(EU)-NSF(USA) Workshop on EXCHANGES & TRENDS IN N ETWORKING 14 Back to basics Is QoS real obstacle or BW is damn cheap? Where are the HW/SW boundaries –Can anything be mapped to a NP Is full convergence essential? –Is IP the last network architecture? –Fast connection network can be separated Should standards define research?
