Federation and Peering

Pre-association Between Providers *SIP Service Providers (SSPs) are said to peer statically when pre-association between providers is required for the initiation of any real-time SIP messages.

Static peering can occur as direct peering (without an intervening layer 5 network) or indirect peering (with a layer 5 network). An example of static peering is a federation. Each of the peers within the federation must first agree on a common set of rules and guidelines for peering, thus pre-associating with each other prior to initiating session requests.

In some cases, an entity (usually a 3rd party or federation) provides peering assistance to the originating SSP by providing this pre-association function. The assisting entity then provides information relating to the peering method (direct or indirect) as necessary.
