2 Outline Hybrid networks and SARA GMPLS in a nutshell The DRAGON Project SARA Conclusion and Recommendations
3 Hybrid networks and SARA
4 Hybrid Networks and SARA What is SARA? IT service centre More then 30 years of experience! High performance networking, infrastructure services and high performance computing and visualization
5 Hybrid Networks and SARA Background information National Research and Education Networks evolved into Hybrid Networks Routed IP and Light path or Optical sections Layer 1 or Layer 2 connections Dedicated Bandwidth and QoS
6 Hybrid Networks and SARA The possible need for GMPLS Increased demand for Light path configuration Manual Light path configuration by NOC!! Time demanding and subject to Human Errors!! Need for automated Light path configuration Automated Light path Research in cooperation with the University of Amsterdam
7 Hybrid Networks and SARA The GMPLS research goals Gain knowledge on Generalized MPLS Get familiar with the DRAGON Project Create a GMPLS capable network by using the DRAGON software Test the DRAGON Software Check RFC compliance of the DRAGON software Research the DRAGON softwares potential for SARA
8 GMPLS in a nutshell
9 GMPLS in a nutshell Key features Support for Packet Switched Capable, Layer2 Switched Capable, Time-Division Multiplex Capable, Lambda Switched Capable and Fiber Switched Capable networks Control- and Data-plane can be physically separated Link Management Protocol Suggested Label Link Bundling

24 The DRAGON Project
25 The DRAGON Project Introduction Dynamic Resource Allocation via GMPLS Optical Networks Open Source GMPLS implementation Goal: Create dynamic, deterministic and manageable endto-end network transport services for high-end E-Science applications Funded by the National Science Foundation (US)
26 The DRAGON Project Building blocks Client System Agent CSA Network Aware Resource Broker NARB Application Specific Topology Builder ASTB Virtual Label Switch Router VLSR
27 The DRAGON Project VLSR Enables non-gmpls capable switches to be used in GMPLS networks Uses Open Source versions of OSPF-TE and RSVP-TE Runs on Unix-based servers Translates GMPLS messages into switch specific protocols such as CLI, SNMP, TL1 and XML
28 The DRAGON Project VLSR
29 The DRAGON Project Implementation HOPI testbed Hybrid Optical & Packet Infrastructure Deploy, test, evolve and evaluate new network technologies and architectures CHEETAH testbed Circuit-switched High-speed End-to-End Transport ArcHitecture

35 SARA Break down a LSP Execution cln_host1-dragon> delete lsp test Test if link fails by sending ping requests over data plane Create and analyze packet dumps Results
36 Conclusion and Recommendations
37 Conclusion and Recommendations GMPLS Can be a solution for Light path Automation Is a robust and divers Technology with good industry acceptance and development Has sufficient Hardware-Based solutions Has limited Software-Based solutions Has one serious OpenSource developer (DRAGON)
38 Conclusion and Recommendations The DRAGON implementation Already capable of basic GMPLS functionality Sponsored Research with high potential, but still under development No support for LMP so far Link bundling expected in the (near) future Can help SARA and the University of Amsterdam get hands-on experience with GMPLS
