  1. Pacific Wave Evolution John Silvester University of Southern California APAN 33, Chiang Mai, Thailand Feb 14, 2012

  2. Early Days • University of Southern California and University of Washington develop local peering exchanges for their communities (remnants of the NSF regionals) due to proximity to major carrier hotels • Emergence of the next generation of REN’s (National and Regional) – purchased services vBNS -> (Abilene) Internet2 Calren (CENIC), PNWGP, …

  3. Dark Fiber – the next Step • .com collapse(c 2000)made acquisition of dark fiber leases possible • CENIC and PNWGP acquire West Coast leases for dark fiber and light to provide multiple waves (CISCO equipment) • Concept of Pacific Wave emerges – distributed exchange on the West Coast of the US to expand reach of the Seattle and Los Angeles peering exchanges using low cost waves

  4. New Model: LA & Seattle Summer 2004

  5. Pacific Wave Peering • Greatly increased no-cost peering opportunities significantly reducing commodity costs for the participants • Concept grew to a larger set of participants over time and eventually led to the national commodity peering partnership with Internet2 • Growth in importance of peering with R&E networks domestically and internationally • Science goes global

  6. International Trans-Pacific R&E Peering • Provided a uniform West facing (trans-Pacific) interface for International Peering • Cost reduction • Facilitating interconnects • Independence from landing points • (later added alternate fiber path to improve resiliency) • Number of connections and bandwidth increases (to 10G) led to addition of additional 10G PW backbone wave

  7. Network Flattening • Growth of regionals, trans-border connections and desire to direct connect to other partners results in a flattening of the network (moving away from the hierarchical structure) • Challenges the business models of the NREN’s

  8. Experimental “Lightpath” Services • Availability of dark fiber led to the development of new networks with the ability to provision lambdas, circuits, lightpaths, capacitated virtual circuits • Fast take up by “big science” eventually maturing (?) into NREN architectures and service models providing static and dynamic “lightpaths” (of various flavours)

  9. Exchanges slow to Adopt • Most exchanges are slow to provision the new services as they wait for agreement on what tools should be used for inter-domain lightpaths; and the fact that most International circuits do not support lightpaths • Exchanges mostly only support static lightpaths requiring manual interventions • But this is changing and SDN reinforces this shift • 2012 may be the year of Dynamically reconfigurable Inter-domain Lightpath deployment on a global scale. • WIP (work in progress) at PW - see Thursday presentation for more details

  10. Other Drivers for Capacitated VC’s • Bandwidth upgrades • Internet2 => 100G • 40G in other NREN backbones and some International links • Trans-Pacific 40G coming real soon now! • Provides the scaling needed for CVC’s to be economically feasible • Network research (GENI, SDN, …) needs (and can help provide) these capabilities

  11. Recent Developments • CENIC/PNWGP and Internet2 partner to provision 100G on the US West Coast (win-win) • Allows for upgrades of the PW core to 100G (and even multiple 100G as necessary) • Plans afoot for dynamic lightpaths through PW • Rethinking of Gigapop as Exchange Point in the Internet2 network, with Internet2 becoming a provider of LP’s through the network

  12. Distributed GOLE’s?? • One expectation of a GOLE is that it be non-blocking between participants. • This is hard (or expensive) for a distributed GOLE to provide • Presents an interesting challenge for PW • Split into 3 GOLES • Continue to provide transparent (free) POP interconnect (in a non-blocking way) • or <fill in the blank>
