Capacity at this IXP

5,815 Gbps

Cumulative port speeds of all IXP members. This shows the potential maximum traffic that can be exchanged at this IXP at one time.

Membership and capacity

The size and strength of an IXP is determined by a combination of how many members it has, and the total capacity. Larger networks tend to bring more capacity, which can benefit all members.
