David Morton, PNWGP

RENU Technology Workshop


Introduction

Introduction

  • Our many jobs:

    • University of Washington

    • Pacific Northwest Gigapop

    • Pacific Wave

    • Operate regional and state networks

  • Pacific Northwest Gigapop (PNWGP) - Regional and International interconnection point for:

    • Pacific Wave (including IEEAF link to Tokyo)

    • National R&E Networks (National Lamba Rail, Internet2)

    • Regional and State networks (Northern Tier, K20, other Universities in the region

    • Enabling advanced research in a wide variety of topics.

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 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

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
