Next gen lan infrastructure

  1. 1. NextGen LAN Infrastructure What does the Next Generation LAN look like?
  2. 2. Panelists • Jeremy Littlejohn – President, RISC Networks Inc.
  3. 3. NextGen LAN Challenges
  4. 4. Current LAN Shortcomings Total Have Avg. Have Avg. Uplinks Errors Errors Discards Discards • Ethernet is Lossy 5923 446 2209015 142 89432 – Much worse that Fibre Channel – Even worse when poorly executed • Current Topologies are Inefficient – Spanning Tree is beautiful but dated • Wireless LAN (802.11 a/b/g) – Works but is very crowded • Aggregation points are choke points
  5. 5. Does Loss Matter? Source: NetEx
  6. 6. Top NextGen LAN Challenges • More Efficient – TRILL / 802.1aq Low Latency Lossless – MPLS / VPLS in the LAN • Mobility Low Jitter – 802.11n • Speed – 10 Gbps Ethernet Success • Adaptability – DCB (Data Center Bridging)
  7. 7. 10 GB Ethernet Saturation • 109 Customers 300000 • 34 Have 250000 250,039 10Gbps 200000 • 2,271 Average 150000 135,870 Nodes 100000 • Only 396 10Gbps 50000 ports in use 871 0 1.0 Gbps 10 Gbps 100 Mbps
  8. 8. Some Vendor-ese I heard this week • Network needs to be Simpler • Network must become Flat • Open Standards are the reason that our product works • Virtual Machines are flying all over the place
  9. 9. What do You Think? • Thank you for participating!
