PEER INTO THE FUTURE OF INTERNET CONNECTIVITY

While some of the leading cloud platforms offer speed and performance of networks companies a direct, dedicated connection, the vast majority of and can be based on a range of cloud and content services still require the Internet for access. private and public peering models As a result, peering at an Internet Exchange has become an that allow for different business increasingly important part of the interconnection strategy for arrangements businesses that need to ensure the performance and resilience of their networks.

Private Or Public Peering? 1. Private Network Interconnections These offer several options: • Connection organised between two networks, who manage the fibre and connection themselves and exchange traffic for free • In some cases, if a smaller network wants to exchange traffic with a much larger network a financial transaction will take place • Can be organised through the data centre if the two networks are both colocated • Netnod’s Optical IX can also interconnect networks at different data centres

2. Public Peering at an Internet Exchange (IX) Connect through an Internet Exchange and peer with any other network present at the location. This provides exceptional performance, a wide choice of peering partners and low cost of traffic.

ROUTE SERVERS One of the tools available to networks that peer publicly. They enable you to easily peer with hundreds of networks using just one connection. Nearly 70% of connected networks at Netnod are available through its route servers. Why You Should Consider Peering Robust and resilient network interconnections are the key to doing digital business and enabling advanced networking capabilities. Peering can help here by removing the single point of failure associated with relying on a single ISP to handle your Internet traffic. Peering enables networks to scale by handling increasing volumes of traffic while offering improved performance and much lower latency. The key advantages of peering include:

PERFORMANCE SPEED Communicating with networks and other businesses Peering enables businesses to keep traffic local, directly brings you closer to users. Instead of reduce latency and avoid the possibilities of backhauling on a transit route, you ensure that you congested ISP routes and networks. keep traffic local and reduce latency. The end user experience is improved and your network has resilient connectivity to the networks and content FINANCIAL SAVINGS providers that matter most for your business. Peering is an attractive option for businesses that transmit large amounts of data. It helps you reduce the cost of your network traffic by avoiding expensive IP transit costs. RESILIENCE Relying on one route for your network traffic means you have a single point of failure. Peering gives you CONTROL multiple routes enabling you to mitigate risk, increase Peering offers more control over external paths, and routing redundancy and ensure the resilience of your network. can easily be adjusted to avoid problem network segments. Getting Started with Peering Any business that uses cloud-based software or applications can benefit from peering to ensure availability, resilience and increased performance. As Internet connectivity evolves, all kinds of networks benefit from the presence at an Internet Exchange of transit providers, cloud providers, Content Delivery Networks, Internet Service Providers and Enterprises.

How to Get Started Before joining an Internet Exchange • Establish an Autonomous System Number (ASN) consider which organisations are already • Set up a router to connect to a port at the Internet Exchange present and whether it is home to major • To reach the most peers, start peering with the Internet Exchange route server content providers, cloud providers, ISPs • Start to establish peering relationships with the big players in your region and the networks and other networks with customers and of most relevance to your business and customers routes relevant to your business

WHAT IS AN AUTONOMOUS SYSTEM NUMBER (ASN)? WHAT IS A PORT? An ASN is a unique global number A port is the connection point for that enables a network to exchange networks connecting to an Internet traffic with other networks and enables Exchange. Port speeds available range these networks to communicate their from 1 Gigabit per second to 10 and routing preferences. even 100 Gigabit per second.
