2 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 2
3 Proposed evlbi Phase 1 Shared Test Configuration Achieves approximately 1 Gigabit per second (GB bps) end-to-end but can only be used for time-limited demos as it uses shared MAX and /High End Computer Network (HECN) project network infrastructure between ISI-E and GGAO Potential evlbi Phase 1 Dedicated Test Configuration Builds on technical approach validated in Phase 1 replacing shared MAX and /HECN network infrastructure with evlbi-dedicated network infrastructure 3

8 Phase 1 Notes At Haystack and MIT/LL» Info source is Haystack s Alan Whitney and MIT/LL Steven Bernstein s 5/1/01 Lincoln Optical Fiber Network Infrastructure ppt» Assumes a VLBI Mark 5 unit or a VLBI Correlator and at least one suitable workstation are Gigabit Ethernet () connected to a Haystack local switch which is connected through MIT/LL (details not important here but are available from MIT/LL or Haystack) to BoSSNET» Workstation will be used for end-to-end checkout testing with a comparable workstation unit at GGAO» Questions/issues: TBD 8
9 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 to a local switch (and is planned to be replaced with a 2.4 Gbps POS user interface to the ISI-E s M40 )» Assumes Supernet/BoSSNet IP peering with MAX is prearranged (to be resolved between DARPA and MAX)» Assumes simple physical switch interconnection among BoSSNET, ISI-E switch, and MAX s M160 (until replaced by 2.4 Gbps POS interconnection among BoSSNET, ISI-E M40, and MAX s M160 )» Questions/issues: Maximum MTU size of M160 supported frames bytes? 9
10 Phase 1 Notes At MAX s UMCP site» Info sources are s Bill Fink and MAX s Jerry Sobieski and Dan Magorian» Leverages /HECN s existing and planned interfaces to MAX s M160 and switch over today s existing (only) one fiber pair*. One link exists today to/from a /HECN-acquired Course with two 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 switch) for each of the lambdas? Jumbo frames are not presently supported on existing switch, but MAX may be planning an upgrade soon. This need more investigation and discussion. 10
11 Phase 1 Notes At /HECN s Building 28 site» Info sources are s Bill Fink and Paul Lang» Leverages /HECN s existing and planned interfaces to MAX s M160 and switch over today s existing (only) one fiber pair*. One link exists today to/from a /HECN-acquired Course with two 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 or switch) for each of the lambdas? Jumbo frames are not presently supported on existing 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 11
12 Phase 1 Notes At /GGAO s Trailer near Building 202 site» Info sources are s Lee Foster, Herb Durbeck and Scott Douglas» Need fiber pair between B28/W220 (via B10) and GGAO trailer near B202 Douglas 7/2/01 identified cost of a fiber pair between B28 and Area 200 ~$10K» Need switch with jumbo frame support at GGAO Recommend Extreme Network Summit 1i with one LX and two 1000BaseT ports» Proposes Mac G4 with 1000BaseT NIC as test workstation ~$ 6K Similar to Fink s recent acquisitions ~$ 3K» Assumes a VLBI Mark 5 unit with 1000BaseT NIC» Questions/issues: Need to confirm Mark 5 s NIC is 1000BaseT 12
13 Potential evlbi Phase 1 Dedicated Test Configuration (Same as Phase 1 Shared Test Config except were noted) At Haystack and MIT/LL: no change At ISI-E:» Need one additional port on M160 ~$13K Between MAX/ISI-E and MAX/UMCP:» Need additional fiber pair or lease a lambda from MAX TBD At MAX/UMCP:» Need two additional ports on M160 ~$25K Between UMCP and /HECN» Need additional fiber pair or add a lambda ~$20K» Need additional LX port on HECN switch ~$5K 13
