This post is a continuation of last week's Network Automation and dives into Strategic Peering.
For organizations building a Global IP Backbone, strategic point of presence (POP) placement and strategic peering are essential to gaining the best possible performance and routing visibility. With many choices of carrier-neutral vendors and facilities available, organizations can plan their backbone and network locations within close proximity of nearly any network needed for interconnection. The benefits include direct peering with major transit providers, Internet Exchange Points, Cloud Service Providers and Direct Cross Connects with customers, business partners, CDNs, etc.
When combining strategic POP placement and peering, organizations can shorten the cable between their network and customers, along with any networks needed for building resources, such as Cloud Service Providers and CDNs. As an example, a network can be built in major markets on both coasts. On the east coast, POPs built in the New York and Washington DC metro areas offer many options for establishing peering to networks of choice. Likewise, adding POPs in the San Francisco Bay Area and Seattle are examples of West Coast coverage. These locations can be interconnected with transport services to complete the backbone for your organization.
Today, peering sessions can be built in each major metro area of the backbone in order to announce networks that can be locally served in those areas. This example essentially shortens the path. Network services can be built and replicated at each location, thereby increasing the likelihood that customers will ingress at the closest POP (i.e. customers located on the West Coast will have a high probability of ingressing at San Francisco or Seattle). If the desired service is at each location, the traffic will be handled locally or will route to the nearest POP across the backbone.
One of the keys to establishing this environment is peering on an Internet Exchange Point (IXP). When an IXP link is established, networks can peer with other IXP networks in a given region. This method allows companies who exchange significant traffic to form a peering relationship over the exchange, resulting in direct traffic exchanges between the networks and thus eliminating the need to rely on costly Internet transit. Another option is to form a direct connection within the same carrier-neutral facility if private peering is desired.
This is just one example of a strategy that can be used to build a Global IP backbone with multiple POPs, strategic peering arrangements, and connectivity options to increase performance and routing visibility on the Internet. The end result enables you to be closer to your customers and partners, leading to higher service quality and reduced costs.
