About SIX Seattle (Jumbo)

This is the 9000-byte MTU VLAN of the Seattle Internet Exchange, a peering LAN in its own right on 149.112.96.0/22 and 2001:504:16:1::/64 running alongside the exchange's 1500-byte VLAN. It is not a separate connection: the operator trunks it onto a member's existing circuit, so it consumes no additional port and reaches the same buildings as the standard VLAN. The membership is its own, though. 67 networks connect over 77 ports for 3.6 Tbps of connected capacity, and the mix leans heavily toward research and education — ESnet, Internet2, CANARIE, AARNet and Pacific Northwest Gigapop are all here, the constituency that most often asks for 9000-byte frames. Hurricane Electric holds 800G.

Traffic

Getting connected
The VLAN is trunked onto a member's existing circuit rather than sold as a second connection, so it needs a tagged port but no additional port. A network applying to the exchange states on its request whether it will take the 9000-byte VLAN; an already-connected participant asks the operator to trunk its circuit
