How do Interconnections work for dummiez

User Flows

User starts by making a API call to POST /projects/:id/connections. When they make this request they are able to either able to use a full dedicated port, on which they get the full bandwidth, or they can use a shared port. The dedicated port promises you get the full bandwidth, but is more costly.

A user is also able to to select whether the connection at metal is the A side or the Z side. If it's the A-side, then Metal does the billing, if it's the Z-side, Fabric takes care of the billing.

A-side/Z-Side is a telecom terminology, where the A-side is the requester and the Z side is the destination. So in the case of connecting to a CSP, we're concerned with a-side from metal because that means we're making use of Fabric as a service provider to give us connection to the CSP within the metro.

If we were making z-side connnections, we'd be granting someone else in the DC access to our networks.

Under the Hood

when the request comes in we create

  • An interconnection object to represent the request
  • Virtual Ports
  • Virtual circuits associated with each port
  • A service token for each
