A comparison of homogeneous hierarchical interconnection structures

Article Abstract:

There is a basic difference between multicomputers and multiprocessors. Multicomputers are made up of full-functioning autonomous processing elements that have local memory. Multiprocessors are systems that interconnect memory modules and computing modules. There are a number of topologic arrangements used for hierarchical multicomputers. Bus oriented architectures have in common the arrangement of processing elements in the module. Among bus oriented architectures are the snowflake, dense snowflake, and star. Link oriented architectures have an incremental strategy that is not based on the module, but relies directly on the nodes. The basic structure of this family is regular trees, but it also includes ringed trees, hypertrees, multitrees, flip-trees, bin, quad, and generalized pyramids.

The Application Layer of the Reference Model of Open Systems Interconnection

Article Abstract:

The Application layer of the Open Systems Interconnection (OSI) Reference Model is used for communicating among distributed application processes which cooperate for information processing. This layer and the Presentation Layer are concerned with semantics and syntax of exchanged information. The Common Application Service Elements (CASEs) and Specific Application Service Elements (SASEs) make up the Application entity along with a user element. Some Common Application Service Elements are summarized. Diagrams illustrate semantics and layer relationships.

The Special Issue on Open Systems Interconnection (OSI)- New International Standards Architecture and Protocols

Article Abstract:

In the early 1960s the International Organization for Standardization (ISO) organized the Technical Committee 97 on Information Processing Sytems. A subcommittee, SC 16, was formed to develop a reference model that would be a standard for all future distributed information systems. The basic architecture of the Open Systems Interconnection (OSI) was specified in ISO International Standard 7498 and CCITT Recommendation X200.
