1 End-to-End GMPLS Signaling in CHEETAH Project Xiangfei Zhu xzhu@cs.virginia.edu 5/5/2005 Master’s Project Presentation

2 Outline CHEETAH project overview GMPLS signaling overview End host software for GMPLS signaling External GMPLS signaling Engine for Cisco 15454 Network setup and experiments Conclusion and future work

3 CHEETAH Project CHEETAH: Circuit-switched High-speed End-to-End Transport ArcHitecture[1] Supported by NSF Experimental Infrastructure Networks (EIN) Project Goal: enable dynamically controlled rate-guaranteed connections between end hosts Application: eScience community, especially, Terascale Supernova Initiative (TSI ) High speed file transfer Remote visualization

4 CHEETAH Network Overview NC NCSU Control card OC192 card GbE/ 10GbE card X1 ORNL SN16000 OC192 card Control card GbE card NCSU/MCNC/NLR SN16000 OC192 card Control card Atlanta (NLR/SOX) SN16000 OC192 card OC-192 GbE/ 10GbE card … Centaur Lab

5 Optical Network Signaling GMPLS: Work in progress at IETF RFC2205 – RSVP for IP network RFC3209 – RSVP-TE for MPLS RFC3471 & RFC3473 – RSVP-TE for GMPLS RFC3946 – SONET and SDH Optical Internetworking Forum (OIF) UNI, I-NNI, E-NNI International Telecommunications Union (ITU) G.8080 (G.ASON)

6 Vendor Support to GMPLS Some vendors provide varying-level support for GMPLS in their products eg: CIENA CoreDirector, Sycamore SN16000, etc. Successful multi-vendor GMPLS interoperability demo at ISOCORE The implementation of GMPLS signaling by different vendors are basically compatible

7 University GMPLS Code KOM RSVP Engine – Technische Universitat Darmstadt [7] partial support of RFC 2205, 2210 & 3209 Dragon RSVP-TE code – MAX/ISI [4] partial support of RFC 3471, 3473 & 3946 Use of the university GMPLS code GMPLS client on end hosts External GMPLS engine

8 My contributions Implement a GMPLS software for end host – “Bandwidth manager” Integrating GMPLS signaling with Admission control OCS (Optical Connectivity Service) Integrate with 15454 control software CHEETAH network setup and interoperability test with Sycamore SN16000

9 End host Context Routing decision: Decide use CHEETAH circuit or Internet to transfer the file base on the Internet congestion status and file size FRTP: Fixed-Rate Transport Protocol designed for circuit- switched network [6] Bandwidth Manager: Dynamic provision of the circuit Internet PC NIC I PC FRTP Bandwidth Manager FTP TCP/IP FTP Routing decision Routing decision NIC II CHEETAH Network NIC I [3] Bandwidth Manager

10 Bandwidth Manager Architecture

11 Bandwidth Manager Daemon Read the configuration from a configuration file. Initiate circuit setup. Accept the bandwidth request Check if destination is in CHEETAH network (OCS) Bandwidth management (CAC) Create RSVP session and send out PATH message Update ARP/IP table Accept the circuit setup requests Listen to PATH message If it is a new session Perform CAC Create a new session and send back RESV Update ARP/IP table PATH

12 Bandwidth Manager User Interfaces bwadmin - provide an interface for system administrators The configuration set by administrator is stored in a configuration file. Commands supported: bwadmin show bwadmin set control-plane-ip IPADDR bwadmin add telink …. (TElink information) bwadmin del telink ID bwrequestor - provide command for end users to request a bandwidth. bwrequestor DESTINATION-DOMAIN-NAME BANDWIDTH

13 Bandwidth Manager Configuration File The configuration file includes: The control-plane address of the node TE-link information: TE-link ID Bandwidth and type (Ethernet/SONET) Interface types (numbered or unnumbered) of the two interfaces (local and remote) IP (numbered interface) / IFID (unnumbered) of each interface A sample configuration file control-plane-IP = 128.143.137.155 # TE-Links # TELinkID bandwidth(unit: Mbit) link type (0-Ethernet, 1-SONET) local interface type (0-unnumbered, 1-numbered) local interface IP/ID remote interface type (0-unnumbered, 1-numbered) remote interface IP/ID TELink1 1000 0 0 1 0 1 TELink2 500 0 1 192.168.2.1 1 192.168.2.2

14 My contributions Implement a GMPLS software for end host – “Bandwidth manager” Integrating GMPLS signaling with Admission control OCS (Optical Connectivity Service) Integrate with 15454 control software CHEETAH network setup and interoperability test with Sycamore SN16000

15 External GMPLS Engine for Equipment without GMPLS Capability Dragon’s VLSR (Virtual Label Switching Router)[4] as an external GMPLS engine. RSVP-TE message parsing and construction is done Fabric programming module for some Ethernet switches through SNMP Adopt VLSR for Cisco 15454 Monfox TL1 Library Allows for an external program to provision circuits by issuing TL1 commands to 15454 Difficulty: Library in Java while the Dragon code is in C++  Figured out how to integrate Java code with C++ through CNI (Cygnus Native Interface) (by Lingling Cui) Integrate Dragon’s RSVP-TE software with 15454 control software

17 My contributions Implement a GMPLS software for end host – “Bandwidth manager” Integrating GMPLS signaling with Admission control OCS (Optical Connectivity Service) Integrate with 15454 control software CHEETAH network setup and interoperability test with Sycamore SN16000

18 July 26, 2004 First interoperability at Sycamore

19 PATH message RESV message Did find some bugs in Dragon’s code but bugs were fixed on-the-fly

20 Nov 6-12, 2004 Supercomputing 04’ Demo 1: A web application integrated with: dynamic circuit setup and release (RSVP-TE) bandwidth manager on end host external RSVP-TE control engine for Cisco 15454 MSPP a transport protocol designed for dedicated circuits (FRTP – Fixed Rate Transport Protocol) Demo 2: Signaling interoperability with Sycamore SN16000

22 SN16000 Atlanta (NLR/SOX) May 28, 2005 CHEETAH Atlanta Deployment NC NCSU Control card OC192 card GbE/ 10GbE card X1 ORNL SN16000 OC192 card Control card GbE card NCSU/MCNC/NLR SN16000 OC192 card Control card Atlanta (NLR/SOX) SN16000 OC192 card OC-192 GbE/ 10GbE card … Centaur Lab Control card OC192 card GbE/ 10GbE card

23 Experiments with Sycamore SN16000– SONET-to-SONET OC192 GbE 34 35 1-6-1-1 1-6-17-1 1-7-1-1 1-7-17-1 Route ID/Switch IP/Eth Address: 128.109.34.18 Eth1 128.109.34.18 1-8-33-1 SN16000-NC End Host 2 End Host 1 Internet SONET TE-Link Fiber Provisioned Cross Connection Dynamic Cross Connection RSVP-TE Signaling

24 Performance For repeated circuit setup and release, average circuit setup time is 159ms. However, the first circuit setup is usually around 270ms. The extra time is suspected to be consumed by ARP and probably routing table lookup

25 Experiment with Cisco 15454

26 Performance Performance of external GMPLS engine for MSPP[5] Time for crossconnection setup: STS-1: 17.833 ± 0.184 ms STS-3: 18.000 ± 0.081 ms Time for crossconnection delete: STS-1: 16.400 ± 0.175 ms STS-3: 16.300 ± 0.145 ms

27 Conclusion It is feasible to extend dedicated circuits to end hosts by running RSVP-TE software on end hosts It is feasible to add GMPLS signaling capability to devices without build-in GMPLS capability The standards are mature and vendor implementation is good

28 Future Work Development part Complete the implementation Hand out to scientists to use Research part Bandwidth scheduling of circuit-switched network Immediate call vs. scheduled call Distributed bandwidth scheduling
