  7. 7. NGN Enterprise Switching Requirements Past Future Up to 1 Gbps 10 Gbps 100% L2 / 20% L3 100% L2 and L3 Limited L4-7 awareness Full L4-7 awareness Single protocol Multi-protocol in native form; Protocol conversion/encapsulation @ wire speed Separate LAN/SAN switches Unified LAN/SAN switches Blocking enterprise switches Non-blocking enterprise switches IP-sized memory buffers XML-sized memory buffers Limited programmability Substantial programmability @ wirespeed Pre-installed programming On-the-fly programmability ® 7
  8. 8. Issue: Supporting The Underlying Demand Switches Line Cards ● Need enterprise ● Need to adopt PCI switches with capacities Express @ 10G once associated with ● Need RDMA to offload the core microprocessors ● But with much more ● Need flexibility and flexibility and programmability programmability ● Price under $100! ● And at low prices: sub $500 per port ® 8
