Context

• MPLS VPN over MCIs vBNS
• IP, ATM, VPLS over MPLS
• IPsec, IPv6, jumbo frame
• OC192 WAN
• 120 RDTE sites, DS3 to OC48

3
Optical Services

• Light Path in existing contract with MCI
• Details and dates TBD
• Useful for linking optical testbeds (like GIG-EF)
  over the wide area
• May be applicable to large bulk flows
• Optical separation for security?

4
Optical Technology

• Under the covers
• Ultra Long Haul (ULH)
• GMPLS
• G.709
• Visible to DREN?
• WDM for fiber bandwidth expansion

5
Interoperability Issues

• Will have mostly IP / BGP interfaces to other
  networks
• IP is not the problem
• But L2 interoperability could be useful
• e.g. Virtual Private LAN Services (VPLS)
• L1/ L2 solutions might help resource sharing
  between different nets

6
Key Themes and Issues

• We buy what we can afford
• Fast / Cheap / Secure choose one
• Commercial services
• Share public infrastructure
• Offerings in this area are TBD
• QoS at L1 / L2

7
Key Research

• Encryption
• IP over xyz (Ether, ATM, SONET, )
• Monitoring
• SNMP, NetFlow, sFlow, AMP
• Testing and Debugging
• Role of GMPLS, G.709, GFP
