Switch Interconnection Policy:
Members may only utilize a single layer-2 MAC address and place a single layer-3 router per port allocated from the JXIX switch fabric unless by prior agreement of the Governing Board. The procedure for interconnecting a layer-2 device to the JXIX will be as follows: a technical proposal shall be made to the Governing Board, accompanied by full documentation. This documentation shall be published on the announcement mailing list and the JXIX web site for comment by current members and the public for no less than two weeks, whereupon the Governing Board shall determine whether the operator is allowed to perform the proposed interconnection. No more than one such proposal shall be considered at a time. Any subsequent modifications to the interconnected equipment must be similarly approved by the Governing Board. The operator is responsible for maintaining any required documentation of all layer-2 devices comprising the switch fabric, and such documentation shall be available to JXIX operations volunteers.
JXIX Switch Fabric Extension:
A participant, facility operator, or other parties may wish to extend the JXIX switch fabric with an additional layer-2 switch. This proposal shall publish for comment by the participants and the public for no less than two weeks, following which the Governing Board shall determine whether the operator may perform the proposed interconnection. When approved, extensions shall be allocated a port or LAG group on the JXIX core switch of sufficient capacity to accommodate traffic, and that port shall not have static MAC address limitations imposed. Participants exist in a single class, regardless of whether they connect to a JXIX core switch or an extension switch. They receive their peering subnet IP addresses directly from the Governing Board and are subject to all of the same rights and responsibilities defined in this document.
No more than one switch fabric extension proposal shall be considered at a time, and any subsequent modifications to the interconnected equipment shall be subject to prior approval by the Governing Board. The Extension Switch Operator is responsible for maintaining documentation of all OSI layer 2 devices comprising the switch fabric to the Governing Board’s satisfaction, and such documentation shall always be available to the Governing Board.
Switch fabric extensions proposals will be judged on their technical merits and the competence of the proposed operator. The Governing Board shall not withhold approval for a switch fabric extension for anti-competitive reasons.
JXIX Switch Fabric Extension Congestion Management:
Because the commonly-used five-minute average traffic statistics mask congestion-causing traffic, extension ports peaking above 65% average utilization within five minutes for three consecutive days shall receive additional or larger JXIX core switch ports as necessary. This is necessary to bring the peak utilization below the upgrade threshold. The Extension Switch Operator shall be obligated to use those ports to increase interconnection bandwidth to their extension switch at their own cost.
If an extension port peaks above 90% utilization, or if there is active packet loss, the Governing Board shall notify participants connected to the extension switch.
