Key Aspects of eVLBI Network Design with Emphasis Between BoSSNET’s POP at ISI-E and the GGAO at GSFC Prepared by J. Patrick Gary Network Projects Leader Earth and Space Data Computing Division/Code 930 NASA Goddard Space Flight Center pat.gary@gsfc.nasa.gov 301-286-9539 September 25, 2001 J. P. Gary 9/25/01 1 Key Aspects of eVLBI Network Design with Emphasis Between BoSSNET’s POP at ISI-E and the GGAO at GSFC Preface ● ● ● ● All info is essentially DRAFT; much more detailed planning is required This info makes many assumptions few of which are yet adequately described but all need to be Further planning needs to be based better on a clearer understanding of this project’s requirements, timetable, and actual funding support All references to UMCP-led Mid-Atlantic Crossroads (MAX) cooperation is assumed, but no MAX commitments have yet been negotiated; we just haven’t yet had time to discuss this more thoroughly with them J. P. Gary 9/25/01 2 Key Aspects of eVLBI Network Design with Emphasis Between BoSSNET’s POP at ISI-E and the GGAO at GSFC Proposed eVLBI Phase 1 “Shared GE” Test Configuration ● Achieves approximately 1 Gigabit per second (GB ˚b ps) end-to-end but can only be used for time-limited demos as it uses shared MAX and GSFC/High End Computer Network (HECN) project network infrastructure between ISI-E and GGAO Potential eVLBI Phase 1 “Dedicated GE” Test Configuration ● Builds on technical approach validated in Phase 1 replacing shared MAX and GSFC/HECN network infrastructure with eVLBI-dedicated network infrastructure J.

P. Gary 9/25/01 8 Key Aspects of eVLBI Network Design with Emphasis Between BoSSNET’s POP at ISI-E and the GGAO at GSFC Phase 1 Notes ● At ISI-E » Info source is ISI-E’s Tom Lehman » Leverages BoSSNET’s existing termination/CPE user interface which presently is essentially a GE to a local GE switch (and is planned to be replaced with a 2.4 Gbps POS user interface to the ISI-E’s M40 router) » Assumes Supernet/BoSSNet IP peering with MAX is prearranged (to be resolved between DARPA and MAX) » Assumes “simple” physical GE switch interconnection among BoSSNET, ISI-E GE switch, and MAX’s M160 router (until replaced by 2.4 Gbps POS interconnection among BoSSNET, ISI-E M40 router, and MAX’s M160 router) » Questions/issues: – Maximum MTU size of M160 supported frames - 4470 bytes? J. P. Gary 9/25/01 9 Key Aspects of eVLBI Network Design with Emphasis Between BoSSNET’s POP at ISI-E and the GGAO at GSFC Phase 1 Notes ● At MAX’s UMCP site » Info sources are GSFC’s Bill Fink and MAX’s Jerry Sobieski and Dan Magorian » Leverages GSFC/HECN’s existing and planned GE interfaces to MAX’s M160 and GE switch over today’s existing (only) one fiber pair*. One GE link exists today to/from a Cisco 3508. GSFC/HECN-acquired Course WDM with two GE lambdas for this fiber pair is expected to be installed before 11/01/01. – *One other fiber pair exists but is dedicated to a semi-operational function » Questions/issues: – What is the UMCP host (M160 or GE switch) for each of the GE lambdas? – Jumbo frames are not presently supported on existing GE switch, but MAX may be planning an upgrade soon. This need more investigation and discussion. J. P. Gary 9/25/01 10 Key Aspects of eVLBI Network Design with Emphasis Between BoSSNET’s POP at ISI-E and the GGAO at GSFC Phase 1 Notes ● At GSFC/HECN’s Building 28 site » Info sources are GSFC’s Bill Fink and Paul Lang » Leverages GSFC/HECN’s existing and planned GE interfaces to MAX’s M160 and GE switch over today’s existing (only) one fiber pair*. One GE link exists today to/from a Cisco 3508. GSFC/HECN-acquired Course WDM with two GE lambdas for this fiber pair is expected to be installed before 11/01/01. – *One other fiber pair exists but is dedicated to a semi-operational function » Questions/issues: – What is the HECN host (GSR 12016 or GE switch) for each of the GE lambdas? – Jumbo frames are not presently supported on existing GE switch, but an Extreme Network Summit 5i with jumbo frame support should be installed before 11/01/01. – Need one LX/1000BaseT converter for the Summit 5i ~$ 2K J.
