Goals

Provide circuit-like options for users who can’t use, or don’t need, a 10G Layer1 wave.

Experiment on future national L2 network capabilities.

  • Create distributed nationwide broadcast domain.
  • Create tools and procedures for automated and user-controlled provisioning of L2 resources.
  • Create network management tools for time-of-day based resource reservation.

nlr l2 services summary7
NLR L2 Services Summary

Initial Services

Dedicated Point to Point Ethernet – VLAN between 2 members with dedicated bandwidth from sub 1G to multiple 1G.

Best Effort Point to Multipoint – Multipoint VLAN with no dedicated bandwidth.

National Peering Fabric – Create a national distributed exchange point, with a single broadcast domain for all members. Initial user ports will be 1GE.

Joint Techs - Feb. 13, 2005

nlr l2 services summary8
NLR L2 Services Summary

Expected Near Term Services

Dedicated Point to Multipoint : Dedicated bandwidth for multipoint connections

Scavenger: Support less-than-best-effort forwarding. This would be useable for all connections.

Connections: Support 10GE user ports

nlr l2 services summary9
NLR L2 Services Summary

Possible Long-range Services

User-controlled Web-based provisioning and configuration Allow users to automatically create new services, or reconfigure existing services on the network using a web-based tool.

Time-sensitive provisioning – Allow users to have L2 connections with bandwidth dedicated only at certain times of day, or certain days.

BGP to each member, with their 2 connections configured any way they’d like. Options include but aren’t limited to: primary/backup, route-based load balanced, or 1 for traffic/1 for measurement.

ISIS core IGP

IPv4 Multicast: PIM, MSDP, MBGP by default.

Features Document

Day One Connection

Each member gets a 10GE connection and a VLAN backhauled over the L2 network to a second node.

General operations of the network, including base features (configuration with no experiment running), connections, and communication of experiments.

Future Possibilities

Peering with other R&E networks.

Commodity Internet Connections or peering.

Sites that had at least 7 of their 8 10GE interfaces assigned at initial installation receive a second 8x10GE, including the MSC and software license.

Houston

These location have a total of 12 XENPAK 10G-LR optics modules.

We call the first configuration “A”, and the configuration with the additional 8x10GE type “B”. The NLR layer 3 network will be comprised initially of 5 type “A” routers and 3 type “B” routers.

Joint Techs - Feb. 13, 2005

layer 3 engineering sub committee recommendations
Layer 3 Engineering sub- committee recommendations
  • Add logical router capability to select sites

Logical routers are a collection of line cards and Route Processors (RP) which together form a distinct router within the chassis. In order to provide additional logical routers for hardware-level separation of services, additional line cards and RP resources must be installed. Logical routers may allow multiple potentially destabilizing experiments to be run simultaneously on the NLR network with the least

  • Add 1GE availability to select sites

This provides a lower speed and less expensive class of interface to which connectors can attach allows for temporary connections, direct monitoring and measurement connections, and direct attachment of reasonably priced experimental tools such as traffic generators and protocol testers.

  • Add additional 10GE to select sites

There are three main reasons for recommending this addition. First, with the base configuration, all but one site is already oversubscribing the slot from day 1. Also, some sites are already completely full and have no room for expansion, even with oversubscription. Although oversubscription may be fine for many experimental scenarios, it would be better to have the option of oversubscription or not, depending on the project at hand. Because the costs are so heavily loaded into the line cards, it is probably unrealistic to expect the “next” connector to absorb the costs of moving to a second 8x10GE card, and it will be a while before 10GE is supported in SPA format. Third, similar to the 1GE line cards recommended above, it provides a more interesting architecture with greater fanout and provides another line card which can be used in the case of logical routers

NLR L3 Services Summary

Private Test-lab Network Connections.

Route Advertiser Connections: Get active commodity routing table for experiments, but no actual commodity bandwidth drainage.

Pre-emptible Connections: Allow other types of connections to use unused ports on a temporary basis, such as for a conference or measurement project.

nlr l3 services summary future options
NLR L3 Services SummaryFuture Options

MPLS (Traffic Engineering, L2/L3 VPNs): This can be done on an experimental basis Day 1. May be rolled into Base Feature list if there is general interest.

IPv6 Multicast: Will be implemented as support and standards mature.

User-Controllable Resource Allocation: Will be supported as experiments, and rolled into the base feature list if there is general use and interest.

Make clear the experiment support model

Service Expectations,

SLA isn’t good measure since the network may appear “down” because of experiments.

Network may not have same uptime as production network, but will have same level of service and support as production network

Joint Techs - Feb. 13, 2005

nlr l3 services summary22
NLR L3 Services Summary

Experiment Support

Each experiment will have a representative from the L2/L3 Support Center and a representative from the ESC.

If necessary, the prospective experiment will be sent to the NNRC for review.

L2/L3 Services staff will be responsible for scheduling network assets for experiments and will see the experiment through to completion.

In general, experiments will be scheduled on a first-come-first-served basis.

nlr l3 services summary network conditions
NLR L3 Services Summary Network Conditions

Way of communicating the current state of the network to users.

Users may choose to have their interfaces automatically shutdown under any Network Conditions they desire.

Users will receive notification of changes to Network Condition, with focused communication to those who will be turned on or off because of it.

Tools will be available for users to monitor and track Network Conditions.
