Understanding Remote Peering – The New Wave of Interconnection at the Core of the Internet. Using real-world case studies, this free webinar explains remote peering and what it means to ISPs, content providers and the global Internet peering ecosystem. Learn from William B. Norton who has presented three popular USTelecom webinars on Internet peering. Background The Internet peering ecosystem is going through a historic and rapid paradigm shift. The largest ISPs and content providers have always interconnected their networks at the core of the Internet using a technique called "Internet peering," the free and reciprocal exchange of access to each other's customers. In this way, networks of scale can exchange a large enough amount of traffic for free with one another to offset the cost of deployment (equipment, colocation, and transport to the colocation center). This justification is the basis for the business case for peering. However, a recent trend -- called "remote peering" -- has emerged as a way to get these peering benefits but without the cost of additional equipment, transport, or colocation. The remote peering model is where a remote peering provider delivers transport to the customer router with Virtual Local Area Network (VLAN) extension(s) from the largest exchange points in the world. In this way, the customer gets all of the benefits of peering (performance, control over routing, direct relationships with the peer networks, etc.) without the large initial capital and operational costs. This is not just a fringe or small change to peering - it is a fundamental shift in the Internet architecture. Remote peering is a new technique that helps make peering accessible to a much larger population. As a result of the cost shift, an increasing percentage of networks are peering across great distances. The peering paradigm of "peering keeps local traffic local" is no more. During the free webinar you will hear case studies from the field where medium-sized content companies are able to enter the peering ecosystem and connect to multiple Internet Exchange Points over a single circuit. These companies have graciously allowed their cost numbers to be shared so the traditional peering model can be compared against the emerging remote peering model. Also, the webinar will highlight the strongest arguments on both sides of the debate over whether remote peering is good or bad for the global Internet peering ecosystem. William B. Norton, Executive Director, DrPeering International and Author of the new 2014 Edition of “The Internet Peering Playbook: Connecting to the Core of the Internet” which includes a new chapter dedicated to remote peering.

Remote Peering is an important topic…

Remote Peering

• Hot Topic• 130 of the 630 at AMS-IX are remote peering• 50% of new at DE-CIX are remote peering

• This is not a fringe peering technique anymore

Internet Transit…

1) INTERNET TRANSITConnecting to the Edge of the Internet

Internet Transit Service Model• 99.9% of all• Announce

Reachability• Metered

Service• Simple• “Internet

This Way”

8Transit Prices Drop

Internet Price Declines (U.S.)

• “Can’t go lower”• “No one is making $”• Pricing varies widely• Trend unmistakable

2) INTERNET PEERINGConnecting to the Core of the Internet

What is Internet Peering?• Definition: Internet Peering is the business relationship whereby two

companies reciprocally provide access to each others’ customers.

Internet Peering3 Key Points

1. Peering is not a transitive relationship2. Peering is not a perfect substitute3. Peering is typically settlement free

12

The Top 5 Motivations to Peer1. Lower Transit Costs

(#1 ISP Motivation to Peer)2. Improve end user experience

(#1 Content Motivation)3. Better control over routing-strategic

(Yahoo!, NetFlix 2008)4. Usage based billing – make more money by peering

(AboveNet)5. Sell more underlying transport capacity

(Telecom Italia)

13Important Traffic is Peered

“Important Traffic is Peered”-- Andreas Sturm, DE-CIX

Transit – your traffic is in same bucket

Peering – you control this traffic

Does Peering cost less?

The Cost of Peering

Transport into DE-CIX$2000/mo local$4000/mo nearby$6000/mo far

15Costs allocated across volume peered…Source: 2010 DE-CIX meeting, Frankfurt

Cost of Internet Peering

Cost of Peering allocated across the amountof traffic peered for free.

16Generalized in Peering Vs. Transit Graph.

• Definition: The Peering Break Even Point is the point where the unit cost of peering exactly equals the unit price of Internet Transit.

17

We will use this graphto compare Transit, Peering and Remote Peering

Market Dynamics affecting these graphs…

Two Peering Market DynamicsPeering Cost Drops…but Transit Prices Drop Faster

18These two dynamics present a modern peering brick wall…

Some question if peering makes sense today…RP

3) REMOTE PEERINGConnecting to the Core of the Internet without additional network gear

Definitions – What is Remote Peering?

• Definition: Remote Peering is peering without a physical presence required at the peering point.

• Definition: A Remote Peering Provider is an entity that sells access to exchange points across their transport infrastructure.

Use Cases…

USE CASESWhat Remote Peering Means to the Internet Peering Ecosystem

For Content Companies

• Important Traffic is peered– Gold plated packets– Remote Peering simplifies– Remote Peering Delivers• Lower people cost• Strategic intent• Performance

• “End-User Performance”• A/B testing and “the blend”

Commodity Transit is cheap,but some applications requiremore control / better performance

Cable Companies…

For Cable Companies / ISPs

• Case: Canadian MSO peers in U.S.

• But Remote Peering in LA and Miami for free Asia and South American Internet routes

Int’l Networks…

For Int’l Networks

• Remote peer into cheap ecosystem– Buy Transit– Peer Away

• 98% Africa traffic from US/Europe

NG Networks…

For NG Networking

• Blend Transit,• Strategic Internet

Traffic is remotely peered

• No capital costs• Control over routing

ISPs peer more…

For Internet Service Providers,Remote Peering justifiesbuilding into more andeven smallish regional IXPs.

More controls over routing

No Capital costs

IMPLICATIONS FOR THE INTERNET PEERING ECOSYSTEM

What Remote Peering Means to the Internet Peering Ecosystem

If there is time…

1) For all Network OperatorsRemote Peeringextends the life of peering

EffectivePeering Range

Peering makes sense across a wider range of Mbps. Peer away 2-3Gbps and all costs are covered.

Breathe of fresh air into Peering

More peersmore IXP value…

2) For IXPs,Remote Peering increasesthe value of IXPs

More new peers, more traffic, more routesMore Valuable IXPs

Colo->instant critical mass

3) For Colocation Centersthe Remote Peering Provider enablesinstant critical mass

ALL PEERING ROUTES ARE REACHABLE!

Reachable peersRemotelymakes colocation center immediately valuable (Value > Cost)

Trials and transition

4) For all, rapid turn-up means Remote Peering enables a fast deployment/transitionstrategy:

1. Remote Peering2. Full Network Deployment

Summary…

Summary Implications and Predictions

Remote Peering will accelerate existing colocation centers to critical mass, allowing them to become peering points andcommand a premium (~$2000/rack vs. $400/rack)

Many more colocation centers will then pop up, with massive power for high-densityVideo server deployments with immediately with access to peering critical mass.

Maybe 1000 peering points across the U.S. to handle massive volumes of video in the next few years.

Remote Peering Summary

• New but rapid adoption• Connect to the Core from afar• $0 Capital Cost• Minimal deployment time• IXP VLANs extended to the

customer router
