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.

Current Meeting Report

Minutes of the IP over IEEE 1394 (ip1394) WG

The goals of this meeting were centered around completing IP unicast. Toward this goal the agenda was to continue with the discussion in progress on the reflector.

At the top of the discussion list was link fragmentation. The only contentious issue left is the presence, or lack of, a length of the link fragment in the link fragment header. For implementing link fragmentation over isoch services on some link chips that don't pass length, we need this field in the parameter. No decisive result, but the next step is to determine how pervasive this problem is today and how long it will likely be present over time. Dirk Brandewie is going to accumulate information then post the results back to the list.

Next topic was the election of the IP manager to allocate and distribute a channel number needed to transfer IP broadcast and ARP packets. Peter Johansson and Dirk worked together prior to the meeting to modify an earlier proposal. The group agreed to move forward with the proposal.

Once we have link fragment header and IP manager election process defined, IP unicast will be complete. A draft with this information is expected in early January. Next steps are IP multicast and Integrated Services.
