Infrastructure

Shared infrastructure is the physical plant that carries the Velocity Interoperability Network between its members. It is held by the Interior Department of the Velocity Interoperability Network on behalf of all members and falls into the classes below. Individual sites and routes are listed in the Register of Sites.

Whatever its class and whichever member built it, every site and route is operated to the service standard, which sets the availability members may expect and the time within which faults are responded to. Works that will affect service are announced in advance in the schedule of planned works, and the land on which each site stands is recorded under Land and Wayleaves.

Relay sites

Staffed and unstaffed sites that carry Network traffic between member organisations. Each relay site is held by the Department and operated to a common service standard.

Exchange points

Neutral locations at which members connect their own networks to one another. Members connect on equal terms under a published exchange agreement.

Data halls

Shared halls in which members may house equipment. Space, power and cooling are allocated by the Department in fixed units and reviewed annually.

Cabling

Ducts, fibre and copper routes between relay sites, exchange points and data halls. Cabling is owned by the Department and leased to members by the route.
