DATA AND FILE TRANSFER WORKSHOP NOTES

On April 14 and 15, 1972, a Data and File Transfer Workshop was held

at M.I.T., Cambridge, Mass. A list of attendees of the meeting for

April 14 and 15 is appended to the notes. This note attempts to

summarize most of the topics discussed and all of the decisions

reached at the workshop meeting.

The following is a summary of the talks and discussions on April 14,

1972.

Steve Crooker discussed a general theory for Network protocols.

Protocols transformations should have a unique inverse, and should be

transitive. Transformation to a standard form requires only 2n

transformations (n = number of different types of hosts), as compared

with n(n-1) transformations with no standard form. A standard

approach is preferable for n >= 3.

For file transfer, one could define a Network Virtual File Image.

There was some discussion on whether it was possible to satisfy the

above rules for file structure transformations. No agreement was

reached and the problem was abandoned for the present.

Further discussion lead to the following formulation of the Workshop

goals:

To come up with data and file transfer protocol/strategy that

satisfies the needs of ARPANET users including Maxi-HOSTs, Mini-

HOSTs, TIPs, Datacomputer, RJE, and Mailbox users.

Goals for the protocols/strategy were set as:

1. It should preserve the integrity of data.

2. It should preserve the integrity of character representation

and interpretation.

3. It should preserve the integrity of structural information, to

the extent conveniently possible.

4. It should lead to the development of a Network Virtual File

System.

Richard Winter discussed the Datacomputer application. The

Datacomputer though usable from terminals directly will not be

engineered for direct terminal users, but for use by programs. In

Datalanguage a user can define data and file structure, and also how

the file/data is to be transferred. Using the data language it is

possible to transfer entire files, or only the relevant parts of

files. The following is an example of file transfer as currently

envisioned in the Datacomputer.

(CREATE statements are needed only when the description(s) required

are not already on file at the Datacomputer. A port description can

specify a standard "external name", thus making a port statement
