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.

  • The Internet Transit service is shown in the diagram below provides access to the global Internet by:announcing the customer route across the Internet so any network on the Internet knows how to reach the customer network, andannouncing to the customer the information necessary to be able to send traffic to any destination in the Internet.In this mini ecosystem, we see the Cyan ISP purchasing transit from the Orange Transit Provider. The Orange ISP announces to the Cyan ISP reachability to the entire Internet (shown as many colored networks to the right of the Transit Providers). The Transit Providers propagate the Cyan route (shown as a cyan circle) across the Internet so that all networks know how to reach the Cyan ISP. With this reciprocal Internet Transit service, all Internet attachments know how to reach the Cyan ISP, and the Cyan ISP knows how to reach all Internet destinations.
  • Why did the 95th percentile come into existence? In the early Internet days, Internet traffic was charged on a circuit capacity basis. But if you didn’t use very much of this capacity, you were still paying as if you did. This made Internet Transit tough to sell so the usage-based (metered) model began. Initially some ISPs charged on average use, which ended up being skewed by the occasional burstiness associated with a spot event. To address this, one ISP adopted the 95th percentile measure that was primarily introduced to not overly punish a customer for the occasional spike in traffic volume, and still allow the ISP to bill based the load placed on its network. This approach seemed palatable and sold. The rest of the industry followed suit and 95-5 was born.
  • WestNet is an ISP with green customers, MidNet is an ISP with blue customers, and EastNet is an ISP with red customers.WestNet is in a Peering relationship with MidNet in which WestNet learns how to reach MidNet's blue customers, and MidNet reciprocally learns how to reach WestNet's green customers.EastNet is in a Peering relationship with MidNet in which EastNet learns how to reach MidNet's blue customers, and MidNet reciprocally learns how to reach EastNet's red customers.After these two peering sessions are established, the routing tables are in place as shown in the boxes beneath the ISP clouds. Since MidNet peers with both EastNet and WestNet, MidNet customers can reach both EastNet and WestNet customers.
  • The Peering Break Even point helps make the business case for peering objective and clear - if an ISP can peer more traffic than indicated by the Peering Break Even Point, then the ISP should prefer to peer instead of solely purchasing transit from an upstream ISP.

  • What is Internet Peering? • Definition: Internet Peering is the business relationship whereby two companies reciprocally provide access to each others’ customers. 11
  • Internet Peering3 Key Points 1. Peering is not a transitive relationship 2. Peering is not a perfect substitute 3. Peering is typically settlement free 12
  • The Top 5 Motivations to Peer 1. 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) 13 Important Traffic is Peered

  • For Internet Service Providers, Remote Peering justifies building into more and even 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 Operators Remote Peering extends the life of peering Effective Peering 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 peersmore IXP value…
  • 2) For IXPs, Remote Peering increases the value of IXPs More new peers, more traffic, more routes More Valuable IXPs Colo->instant critical mass
  • 3) For Colocation Centers the Remote Peering Provider enables instant critical mass ALL PEERING ROUTES ARE REACHABLE! Reachable peersRemotely makes colocation center immediately valuable (Value > Cost) Trials and transition
  • 4) For all, rapid turn-up means Remote Peering enables a fast deployment/transition strategy: 1. Remote Peering 2. Full Network Deployment Summary… Summary Implications and Predictions Remote Peering will accelerate existing colocation centers to critical mass, allowing them to become peering points and command a premium (~$2000/rack vs. $400/rack) Many more colocation centers will then pop up, with massive power for high-density Video 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.
