This document discusses the debate between public vs. private peering. It outlines the top 3 reasons each type of peering is considered better. For public peering, it notes the aggregation benefits, easier administration, and customer preference. For private peering, it cites easier monitoring, very cost effectiveness, more reliability and easier debugging, more security, and signaling as a more desirable peer. The document aims to understand both sides of this ongoing debate between internet service providers.
Understanding Remote Peering - Connecting to the Core of the InternetWilliam Norton
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.
