Community of interest networks (CoINs) are a private network for collaboration between regional consumers that have frequent and commonly shared business practices, applications and services. They are used extensively by the NHS where organisations with similar networking requirements have formed CoINs for regional collaboration. Participants in a CoIN can include health organisations, such as trusts, GPs or pharmacies, and care providers, including local authorities.
CoINs can include a number of network technologies, such as virtual routing and forwarding (VRF), virtual private networks (VPNs), local quality of service (QoS) configurations and managed voice and/or video services that are dedicated to the local community. Where a CoIN connects to the Transition Network (TN, formerly N3) it effectively connects using a gateway architecture approach, shown below.
