  1. Boeing Wireless & Mobility For UW Class on Wireless “Supporting static systems is the degenerate case of mobility and multihoming!!!.” Robert Moskowitz

  2. Agenda • Wireless and Mobility Status • Simple Requirement • Wireless Work Items for 2003 • Next Generation Wireless LANs • Location Enabled Network Services (LENS) • DHCP++ • Measurements for 802.11 and then 802 • Cellular Data to 802.11 Seamless Mobility • WLAN Context Transfer • Wireless Security • Mesh Networks • Layer 2 Routing and Context Transfer Protocols (CTPs) • Host Identity Payload • Big Picture

  3. Wireless and Mobility Status • 1200 Access Points • 60 Foot Cell 802.11b Deployments • Aiming for 802.11a Deployments

  4. Simple Requirement VOIP Over the Wireless LAN!!!!!!!

  5. Next Generation Wireless LANs • Next Generation Wireless LANs • Switch in the closet • Seamless 802.11 Management and Roaming • IEEE 802.11a • Generations 2 and 3 of 802.11a • Technology changes needed for these generations

  6. R Boeing Campus Boeing Wireless Mobility Model Level 4 - National/Intl Low Speed (19.2Kbps) Level 3 - Regional Low Speed Wireless (56Kbps) Level 1 - Personal Area Network (.5-10Mbps) Level 2 - Campus High Speed Wireless LANs (1-100Mbps)

  7. Location Enabled Network Services • Location Enabled Network Services • Vision and Architecture for LENS • Integration of LENS into Network Infrastructure • Triangulation Technologies • Signal Strength Technologies

  8. Location Services Architecture Location Distribution Server & Policy Location Computation Server AAA Server Location Requesting Client

  9. DHCP++ • DHCP++ • Virtual Directory • Real-time Datastore • Next Generation DNS • Next Generation DHCP • Network Provisioning • Mobile Device Provisioning • Autonomous Networks • Other Infrastructure Requirements

  10. DHCP++ Architectural Elements AAA Services Software Distribution Service Policy Services LENS Collaboration Service Virtual Directory Addressing Services DHCP DDNS QoS Service Session Persistence Service

  11. Measurements for 802.11 • Measurements for 802.11 (TGk) • Standards (802.11k) • Autonomous Networks Measurements

  12. AP Measurements 802.11f Context Blob 802.11h Request For Info or 802.11f Context Blob 10/100BaseT AP1 STA1 AP Table Per STA Table Processor Certs Pre-auth User CIM Schema QoS 802.11f Context Blob

  13. Card Measurements AP1 STA1

  14. Cellular Data to WLAN • Cellular Data to WLAN Seamless Mobility • Cellular Data to WLAN Data • Cellular VOIP to WLAN VOIP

  15. WLAN Context Transfer Subnet A 802.11 802.16 Or Cellular R Subnet B 802.11 R 802.11f Context Blob (Certificates, pre-auth, address, etc) 802.11 Context Transfer Packet

  16. Mesh Networks • Mesh Networks • Layer 2 Routing • Layer 2 or 2.5 Context Transfer Protocols

  17. Client Meshing Example • Extends range between 802.11 devices • Off-loads traffic from APs via peer-to-peer links • Increases data rates to distant clients • Reduces number of APs and associated costs

  18. Layer 2 Routing and CTPs • Wireless Layer 2 Routing • Dynamic Backbone Subnets • WLAN Support for VOIP • Context Transfer Protocols • 802.11f • Seamoby’s CTP • Issues about crossing Layer 2/Layer 3 Boundary • Preauthentication • Preauthorization
