Network Exchange Getting Started Guide

Updated by Rob Lesieur on Jun 16, 2017

Product Overview

Network Exchange provides secure, reliable, automated interconnectivity between service networks offered by Network Exchange Providers, including managed hosting, colocation and cloud environments. A Network Exchange Provider is any service provider who has integrated their networking domain for interconnect provisioning by Network Exchange. A Network Exchange User is any credentialed user of Network Exchange who has provider-defined access privileges to two or more Network Exchange Providers. This is the party who ultimately consumes Network Exchange, regardless of the Provider with which they have a direct contractual relationship. An instance of Network Exchange is itself referred to as an Exchange. It is an interconnect between two or more Network Exchange Providers. A Network Exchange User may have one or more Exchanges. A connectivity point for a Network Exchange Provider for a given Exchange is referred to as an Exchange Port. For example, "Colocation" is a type of Exchange Port.

Network Exchange is offered in a pay-as-you-go billing model in which the Network Exchange User pays only for the bandwidth they consume for billable Exchange Port types. Please refer to the Knowledge Base article Network Exchange Billing Guide for details on how billing is calculated.

Note: All equipment and connectivity is redundant in Network Exchange, including cross connects to colocation and direct connect endpoint types. Non-redundant connectivity is not supported.

Glossary

  • Network Exchange: Provides secure, reliable, automated interconnectivity between service networks within a metro-area computing environment.

    • Network Exchange Provider: Any service provider who has integrated their networking domain for interconnect Network Exchange.
      This integration comes in two common sub-types:
      • Software Defined Integration: Dynamic allocation of networks, IPs and routing by an API-driven resource model
      • Configured Integration: Automated allocation of networks, IPs and routing by Provider-defined manual entry for which the Provider is responsible
    • Network Exchange User: Any credentialed users of Network Exchange who has Provider-defined access privileges to two or more Network Exchange Providers. This is the party who ultimately consumes Network Exchange, regardless of the Provider with which they have a direct contractual relationship.
      • Exchange: An interconnect between two or more Network Exchange Providers. A Network Exchange User may have one or more Exchanges.
      • Exchange Port: The connectivity point for a Network Exchange Provider for a given Exchange.
  • Common Provider business models include:

    • Hosted Service Provider: Primarily provides SaaS or managed services on infrastructure hosted by CenturyLink o External Managed Service Provider: Primarily provides services to others on infrastructure not operated by CTL, i.e. IaaS clouds, SaaS platforms, Colocation providers.
    • External Network Service Provider: Primarily provides WAN services, e.g. Level3, Comcast.
    • CenturyLink Managed Service Provider: Any CTL-provided service, e.g. CLC, DCC, Managed Hosting, Network Exchange or CenturyLink Managed Network Provider: Any CTL-provided network, e.g. IQ, CTL-SDWAN
  • On-Net Provider: A service provider, fitting any of the above sub-models, who is directly or indirectly reachable via Network Exchange
  • On-Net Traffic: Network traffic that leaves Network Exchange to a CenturyLink Managed Service Provider, CenturyLink Managed Network Provider or Hosted Service Provider
  • Egress Traffic: Network traffic that leaves Network Exchange to an External Managed Service Provider or External Network Service Provider
  • Network Exchange Reseller: A Provider who also offers white-labeled Network Exchange interconnectivity, providing their customers access to all On-Net Providers.

Q & A

Q: How many Exchanges may an End User have?

A: There are currently no limitations on the number of Exchanges per End User. See the Knowledge Base article Network Exchange Configuration Guide for more details.

Q: How many endpoints may be in an Exchange?

A: An Exchange may include a number of endpoints up to the maximum Exchange Port types available in a metro area served by Network Exchange. See the Knowledge Base article Network Exchange Configuration Guide for more details.

Q: How do I convert from Cloud Network Service to Network Exchange?

A: A Knowledge Base article Migrating from Cloud Network Service to Network Exchange will be provided in the future that will discuss this in detail.

Q: Can I change the name of an Exchange once it’s created.
