NCITS Announces the Approval of Project Proposal, Fibre Channel Second Generation Switch Fabric (FC-SW-2)

Reply to: Deborah J. Donovan at

Washington D.C., April 1998 - NCITS (National Committee for Information Technology Standards) announces approval of this new project being developed within Technical Committee, T11, I/O Interface - Device Level. The reference number for this project is 1305-D.

This proposal recommends the development of a Fibre Channel Second Generation Switch Fabric (FC-SW-2)standard. Included within the recommended scope of this project are extensions to the Inter-Switch Link definition to support:

1) Unicast Path Selection;
2) Coordination of the Common Service definitions being produced by Project 1134-D, Fibre Channel - Generic Services 2 (FC-GS-2);
3) Models of flow control schemes defined by FC-PH-x;
4) Multicast Path Selection;
5) Other enhancements derived from experience with first-generation FC-SW implementations.

It is a key goal of this project that devices meeting the definitions produced herein be backwards compatible with devices meeting the existing FC-SW definitions. Note however that some of the functions based on FC-SW-2 definitions may not be available in configurations which incorporate switches only meeting the FC-SW requirements.

Inquiries regarding this project [project 1305-D] and other Fibre Channel and HIPPI projects should be sent to the Chairman of T11, Mr. Roger Cummings, Distributed Processing Technology, 140 Candace Dr., Maitland, FL 32751. Email:

The next meeting of T11 is April 20-24, 1998, Palm Springs, CA. All organizations and individuals who are materially or directly affected are invited to participate.
