 As a general guideline, private peering link capacity is usually measured in multiples of the physical infrastructure available. For example, today, links in many parts of the Internet are counted in multiples of 10Gbps. The physical link may be 10Gbps even if the peering traffic may only be 1Gbps to 2Gbps. Indeed, provisioning two 1Gbps links for a private peering might well be considerably more expensive than provisioning a single 10Gbps link, even when port and optical transceiver cost is taken into account. As a general guideline, private peering link capacity is usually measured in multiples of the physical infrastructure available.
