Demo #1

File transfer application integrated with CHEETAH

software

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 15454 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!

Demo #1: End-host RSVP-TE client and External RSVP-TE control software for 15454

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 15454 Cisco 15454 MSPP only provides TL1 interface

to provision circuits Need an external RSVP-TE control software,

which can provision circuits by issuing TL1 commands to 15454

Solution: integrated Dragon RSVP-TE software with Monfox Dynamic TL1 library ONS-15454

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

Demo #1: Conclusions Running open-source GMPLS software external to

switches (such as Ethernet based VLAN switches and Cisco’s 15454 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

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
