17-October-2007Pacific Wave & International Peering4 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
5
17-October-2007Pacific Wave & International Peering5 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
6
17-October-2007Pacific Wave & International Peering6 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
7
17-October-2007Pacific Wave & International Peering7 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

20
17-October-2007Pacific Wave & International Peering20 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
21
17-October-2007Pacific Wave & International Peering21 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…)
22
17-October-2007Pacific Wave & International Peering22 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
