The Direct Connections

Pacific Wave & International Peering

pacific wave
Pacific Wave
  • A joint project between Corporation for Education Network Initiatives in California (CENIC), Pacific Northwest Gigapop (PNWGP), University of Southern California (USC), and University of Washington (UW)
  • A distributed Internet Exchange Point (IXP) running the length of the entire United States Pacific Coast
  • Supports high-end networking and protocols, including IPv4 (ucast/mcast), IPv6 (ucast/mcast), Jumbo Frames

Pacific Wave & International Peering

pacific wave initial services
Pacific Wave Initial Services
  • Provide an open infrastructure for connecting international IP networks
  • Facilitate any-to-any connectivity between connectors without the need for involvement of exchange operators
  • Primary connectivity provided via shared VLANs
  • Private VLANs used sparingly on as-needed basis

Pacific Wave & International Peering

characteristics of the service offering
Characteristics of the Service Offering
  • Distributed connectivity using shared broadcast domains
  • Strict connector policy to ensure high availability and uptime
    • Single MAC per VLAN
    • No direct connection of layer-2 switching devices
    • Spanning tree root guard

Pacific Wave & International Peering

what is a distributed ixp
What is a Distributed IXP?
  • A switching fabric that extends beyond the confines of a small geographic region which Internet exchange points typically operate
  • Capable of providing direct connectivity between entities which do not share common, physical presences due to financial, operational, or logistical constraints
  • An architecture which does not define any central or primary point in the infrastructure

Pacific Wave & International Peering

shared vlan infrastructure
Shared VLAN Infrastructure
  • Local, shared VLANs
    • Seattle
    • SF Bay Area
    • Los Angeles
  • Intersite, shared VLANs

the hybrid approach
The Hybrid Approach
  • The hybrid exchange operator can provide easy interconnection between layer-1 and layer-2 devices as necessary
    • Today: manual with physical cross-connect
    • Future: optically switched manually or via control plane protocols
  • Technology choices made based on:
    • Performance requirements
    • Bandwidth requirements
    • Timeframe desired for lightpath activation
    • Availability of wide-area transport

Pacific Wave & International Peering

a distributed gole
A Distributed GOLE?
  • A term as yet defined in the GLIF community
  • What properties might a distributed GOLE (GLIG Optical Lightpath Exchange) have?
    • Multi-transport interconnect between nodes
      • Layer-1 lambda
      • Layer-2 frame mapped (i.e. GFP-F)
      • Layer-2 switched
    • Able to make establish lightpaths between and through the nodes with the efficiency of a single operating entity
    • No bandwidth limitations between nodes (within reason…)

Pacific Wave & International Peering

future
Future
  • Today, Pacific Wave layer-2 switching is a series of linear interconnected fabrics
  • Perhaps more complex wide-area topologies may one day be necessary on the layer-2 network
    • Bandwidth management
    • Resiliency
  • MPLS layer-2 Ethernet VPNs may provide additional opportunities to support future requirements
  • Optical switching facilitates efficient lightpath establishment, especially during technology translation, i.e. frame-mapped  switched Ethernet
