The Yellow Book Transport Service was somewhat misnamed, as it does not fulfill the Transport role in the OSI 7-layer model.

UK set of communication protocols For the compact disc standards series, see Rainbow Books. For the series of U.S. government publications on computer security standards, see Rainbow Series.

The Coloured Book protocols were a set of communication protocols for computer networks developed in the United Kingdom in the 1970s. These protocols were designed to enable communication and data exchange between different computer systems and networks. The name originated with each protocol being identified by the colour of the cover of its specification document. The protocols were in use until the 1990s when the Internet protocol suite came into widespread use.

History

In the mid-1970s, the General Post Office (GPO) worked with the academic community in the United Kingdom and the computer industry to develop a set of standards to enable interoperability among different computer systems based on the X.25 protocol suite for packet-switched wide area network (WAN) communication. First defined in 1975, the standards evolved through experience with the Experimental Packet Switched Service run by Post Office Telecommunications, later known as British Telecom (BT), beginning in 1977. They were used on the SERCnet from 1980, and SWUCN from 1982, both of which became part of the JANET academic network from 1984.

The protocols were influential in the development of computer networks, particularly in the UK, and gained some acceptance internationally as the first complete X.25 standard, and gave the UK "several years lead over other countries".

From late 1991, Internet protocols were adopted on the Janet network instead; they were operated simultaneously for a while, until X.25 support was phased out entirely in August 1997.

Protocols

The standards were defined in several documents, each addressing different aspects of computer network communication. They were identified by the colour of the cover:

The Pink Book

The Pink Book defined protocols for transport over Ethernet. The protocol was basically X.25 level 3 running over LLC2.

The Orange Book

The Orange Book defined protocols for transport over local networks using the Cambridge Ring (computer network).

The Yellow Book

The Yellow Book defined the Yellow Book Transport Service (YBTS) protocol, also known as Network Independent Transport Service (NITS), which was mainly run over X.25. It was developed by the Data Communications Protocols Unit of the Department of Industry in the late 1970s. It could also run over TCP. The Simple Mail Transfer Protocol was extended to allow running over NITS.

The Yellow Book Transport Service was somewhat misnamed, as it does not fulfill the Transport role in the OSI 7-layer model. It really occupies the top of the Network layer, making up for X.25's lack of NSAP addressing at the time, which didn't appear until the X.25 (1980) revision, and wasn't available in implementations for some years afterwards. YBTS used source routing addressing between YBTS nodes—there was no global addressing scheme at that time.

The Green Book

The Green Book defined two protocols to connect terminals across a network: an early version of what became Triple-X PAD running over X.25, and the TS29 protocol modelled on Triple-X PAD, but running over YBTS. It was developed by Post Office Telecommunications. These protocols are similar in functionality to TELNET.

The Fawn Book

The Fawn Book defined the Simple Screen Management Protocol (SSMP)

The Blue Book

The Blue Book defined the Network-Independent File Transfer Protocol (NIFTP), analogous to Internet FTP, running over YBTS. Unlike Internet FTP, NIFTP was intended for batch mode rather than interactive usage.

The Grey Book

The Grey Book defined protocols for e-mail transfer (not file transfer as is sometimes claimed), running over Blue Book FTP.

The Red Book

The Red Book defined the Job Transfer and Manipulation Protocol (JTMP), a mechanism for jobs to be transferred from one computer to another, and for the output to be returned to the originating (or another) computer, running over Blue Book FTP.

Legacy

Further information: JANET NRS

Over time, as technology evolved, many of the concepts and principles from the Coloured Book Protocols were integrated into broader international standards. However, they remain an important part of the hisotry and evolution of computer networking, showcasing an early effort to establish standards and protocols for efficient and reliable communication between computers. One famous quirk of Coloured Book was that components of hostnames used reverse domain name notation as compared to the Internet standard. For example, an address might be user@UK.AC.HATFIELD.STAR instead of user@star.hatfield.ac.uk.
