Description of Working Group:

The goal of the IP1394 Working Group is to define how the Internet Protocol (IPv4 & IPv6) is supported over IEEE 1394 Serial Bus. IEEE 1394 Serial Bus (1394) is specified by IEEE Std 1394-1995 and the draft standard IEEE P1394a. The IP1394 working group intends for the specification to be utilized by devices with a broad range of capabilities. These devices are expected to include (but not be limited to) both traditional equipment such as computers, as well as equipment that has not traditionally been networked, such as consumer electronics (e.g. TVs & VCRs).

Unlike most other data link protocols, IEEE 1394 provides the capability for isochronous as well as asynchronous transmission. This capability can have a significant impact on how IP is supported on 1394. The IP1394 working group will prepare an architecture document and appropriate protocol documents for the usage of these unique link layer properties. Both IPv4 and IPv6 will be addressed, although in separate documents.

The IP1394 working group is chartered to deliver the documents described below. The working group will maintain informal liaison with other standards groups and industry organizations doing related work. Some of these documents may depend upon facilities not currently standardized in 1394. If necessary, working group members will work within the IEEE standards process to request modification or extension of existing IEEE standards (or standards in development).

The deliverable documents are as follows:

- An architecture document detailing the interactions between 1394 asynchronous and isochronous transmissions, resource reservation and multicast.

- An IPv4 over 1394 document covering the encapsulation and framing of IPv4 unicast, multicast and broadcast packets over asynchronous and isochronous 1394, including address resolution.

- An IPv6 over 1394 document covering the encapsulation and framing of IPv6 unicast, multicast and broadcast packets over asynchronous and isochronous 1394, including neighbor discovery.

- A media-specific MIB for managing 1394 interfaces.

Goals and Milestones:

Current Meeting Report

Minutes of the IP Over IEEE 1994 (ip1394) Working Group

I. Interop Event

· Showed slides regarding Interop between Sony, Toshiba, and Intel (slides have been submitted to IETF to be part of proceedings)
· Only spec related issues was related to the NPM election process. Specifically, one of the implementations did not have a usable NETWORK_CHANNELS register until after a driver was loaded. This caused the slow node to not be detected by the faster nodes. If the slower node has highest phs ID, then two node believe they are the NPM. Potential solutions related to the implementation with the problem will be fully examined before attempting to make changes to the spec.
· Another Interop Event is planned in Hillsboro, OR USA in 6-8 weeks with implementations of IP multicast over 1394 expected.

II. Version 7 spec Walk-Through

· Specific derivations from IETF editorial guidelines are to be posted to the WG chair and the Editor for evaluation.
· Other editorial changes are to be made - see next version of draft for details.
· Agreed unicast offset should remain the same through bus reset.
· There were no substantive changes to technical content.

III. IP Multicast Over 1394

· Started with three proposals

· Commonly agreed-on points for all proposals are:

· The remainder of the time was devoted to flushing out the following details of the a proposal related to the MM request/advertise. Here are the details:

· TLVs inside any of the packet types:

· Packet types with required TLVs:
