Infrastructure Supporting Dynamic Circuit Services

High Level Overview:

What are we trying to do?

HOPI Testbed Overview

Deployment on the Internet2 Network

Collaborations with Other Networks

Workshops

Agenda
internet2 network infrastructure with multiple services
Internet2 Network: Infrastructure with Multiple Services

Routed IP Network”

Router Layer

Ethernet Layer

Switched SONET Layer (vcat, lcas)

“SONET Switched Network”

Provisioned

Services

Switched WDM Optical Layer

“Ethernet VLAN Switched Network (i.e., HOPI)”

Multi-Layer GMPLS Networks

Separate (Peering) Control Plane Instantiations for each of the above

overview
Support Applications that demand capabilities that are hard to support in a shared packet infrastructure

Large bandwidth applications

Applications that benefit from circuit characteristics, and that may be low bandwidth in nature

Dynamically create data paths that look like circuits - ”lightpaths”

Networks taking different approaches:

ESnet is taking an MPLS over Ethernet approach

Internet2 (HOPI) taking an Ethernet VLAN approach

Internet2 (Ciena) taking a SONET approach

GEANT is taking a SONET approach

Overview
circuit service types
Circuit Service Types
  • Static Services - Configured by our NOC
    • Ethernet or SONET Framed over Lambda - Directly on the Infinera wave equipment
    • SONET Circuits through the Ciena equipment
    • Ethernet Framed tagged or untagged circuits under SONET via GFP
    • MPLS L2VPNs
  • Dynamic Circuit Service
    • Only through the Ciena equipment at the start, eventually evolving to the full platform
    • Create Circuits in seconds for periods of hours to weeks
hopi and dynamic circuit services
HOPI and Dynamic Circuit Services
  • HOPI provides a testbed
  • Dynamic Circuit Services on Ciena equipment is intended to provide persistent capabilities for applications
    • HOPI will move more towards an experimental facility
    • Capabilities developed on HOPI will migrate to the Ciena platform
  • Two challenges at this time
    • Intra-domain - Integrating the DRAGON GMPLS control plane wo control the Ciena platform
    • Inter-domain - Networks must be able to inter-connect
  • Control plane additions - AAA and scheduling
multi domain control plane
Multi-Domain Control Plane

GEANT

  • Multi-Domain Provisioning
  • Interdomain ENNI (Web Service and OIF/GMPLS)
  • Multi-domain, multi-stage path computation process
  • AAA
  • Scheduling

collaboration with other networks
Working closely with Dante, Canarie, and ESnet on Inter-domain Interoperability

Meetings in December and January, to continue in May

Much ongoing work to utilize existing technologies

Will meet in May after TERENA 2007

Also participating in the OGF working groups to insure standards compatibility

For example, integrate existing topology disccovery efforts

Collaboration with Other Networks
dragon control plane key components
DRAGON Control Plane - Key Components
  • Network Aware Resource Broker – NARB
    • Intradomain listener, Path Computation, Interdomain Routing
  • Virtual Label Swapping Router – VLSR
    • Open source protocols running on PC act as GMPLS network element (OSPF-TE, RSVP-TE)
    • Control PCs participate in protocol exchanges and provisions covered switch according to protocol events (PATH setup, PATH tear down, state query, etc)
  • Client System Agent – CSA
    • End system or client software for signaling into network (UNI or peer mode)
  • Application Specific Topology Builder – ASTB
    • User Interface and processing which build topologies on behalf of users
    • Topologies are a user specific configuration of multiple LSPs
development team for dcs

what is the hopi service
What is the HOPI Service?
  • Physical Connection:
    • 1 or 10 Gigabit Ethernet
  • Circuit Service:
    • Point to Point Ethernet VLAN Circuit
    • Tagged or Untagged VLANs available
    • Bandwidth provisioning available in 100 Mbps increments
  • How do Clients Request?
    • Client must specify [VLAN ID|ANY ID|Untagged], SRC Address, DST Address, Bandwidth
    • Request mechanism options are GMPLS Peer Mode, GMPLS UNI Mode, Web Services, phone call, email
    • Application Specific Topology is a user specific instantiation of multiple individual circuits

GMPLS ProvisionedEthernet Services
  • Multiple Ethernet Provisioning Options
  • Point to Point Ethernet VLAN based LSPs
  • Ethernet switch (vendor specific) features applied to guarantee LSP bandwidth in increments of 100 Mbit/s
  • Edge connection flexibility provided by use of “Local ID” feature which allows flexible combinations of one port, multiple ports, tagged ports, and untagged ports to be glued on to end of LSP. Can be dynamically adjusted.
  • Users can request services via Peer to Peer GMPLS, UNI style GMPLS, or via an XML application interface

“Local ID” for Egress Control

User Requests:

  • Peer to Peer
  • UNI
  • XML API

VLAN YY LSP

VLAN XX LSP
