2 Demo #1 File transfer application integrated with CHEETAH software

3 Demo #1: introduction A file transfer application integrated with: dynamic circuit setup and release (RSVP-TE) includes end host RSVP-TE clients external RSVP-TE control engine for Cisco MSPP a transport protocol designed for dedicated circuits (FRTP – Fixed Rate Transport Protocol) Pros and cons of rate-guaranteed transfers if load on TCP/IP network increases after the start of a transfer, it would have been a “ good ” thing to have a rate guarantee but, if load on TCP/IP network decreases after the start of the transfer, it would have been a “ bad ” thing to have a rate guarantee!

4 Demo #1: End-host RSVP-TE client and External RSVP-TE control software for End-host RSVP-TE client Original KOM RSVP: partial support of RFC 2205, 2210, 3209 Dragon RSVP-TE: partial support of RFC 3471, 3473 & GMPLS SONET extensions Our work (in progress): Make it compatible with Sycamore SN16000 More support of GMPLS SONET extensions External RSVP-TE control software for Cisco MSPP only provides TL1 interface to provision circuits Need an external RSVP-TE control software, which can provision circuits by issuing TL1 commands to Solution: integrated Dragon RSVP-TE software with Monfox Dynamic TL1 library RSVP-TE software Dynamic TL1 library RSVP-TE messages TL1 commands

6 Demo #1: The Event Flow in Web Application At the web server side Hyperlink to file is a CGI script (download.cgi); filename embedded in hyperlink Download.cgi started automatically at server when user clicks hyperlink, which triggers CHEETAH FT sender CHEETAH FT Sender initiates CHEETAH circuit setup by calling RSVP-TE client. CHEETAH FT Sender starts data transfer using dual paths: FRTP/circuit and TCP/IP At the web client side A RSVP-TE client is running as daemon to accept the circuit setup request A CHEETAH FT receiver is running as daemon to receive the user data Web server (mvstu2) Web client (mvstu3) Web Browser (e.g. Mozilla) Web Server (e.g. Apache) download.cgi Data transfer URL Response RSVP-TE Messages CHEETAH FT receiver FRTP RSVP-TE interface CHEETAH FT sender FRTP RSVP-TE interface RSVP-TE daemon RSVP-TE daemon

7 Demo #1: Conclusions Running open-source GMPLS software external to switches (such as Ethernet based VLAN switches and Cisco ’ s MSPP) is a feasible option. Need to add CAC and route computation functions in external RSVP-TE control software to switches. Circuit provisioning measurements Time for STS-1 circuit provisioning: ~500ms Includes RSVP-TE message processing + TL1 switch config. No release measurement

8 Demo #2 RSVP-TE Signaling Interoperability Testing

9 Demo #2: Interoperability Test Background CHEETAH – Circuit Switched High-Speed End-to-End Transport ArcHitecture An NSF-sponsored project at University of Virginia Sycamore Networks Provider of intelligent optical switching solutions Industry leader in optical control plane technologies Interoperability testing relationship with UVA Sycamore GMPLS software utilized in test

10 Demo #2: Signaling Test Scenario Test elements: Dragon/KOM RSVP-TE client software Sycamore GMPLS software Implementation: End-host RSVP-TE software and Sycamore Networks RSVP- TE software SONET data plane Dynamically controlled circuit creation

11 Demo #2: Signaling Software Interoperability PATH message RESV message

12 Demo #2: Demo Configuration Primary NIC RSVP-TE client MVSTU2 Primary NIC RSVP-TE client MVSTU3 Sycamore switch emulator Tcpdump/Ethereal

13 Signaling interoperability testing successful Vendor implementation of GMPLS protocols is mature, ready for deployment of CHEETAH services (e-science applications) today Key feature requirements for research community network applications Signaling support for Ethernet/SONET hybrid circuits Support for uni-directional circuits Support for scheduled (advanced reservation) calls Demo #2: Conclusions
