Design of a universal protocol subsystem architecture : specification of functions and services
Michael R. Winter · TU/e Research Portal · 1989
This paper describes a framework of a Protocol Subsystem Architecture using a maximum of parallelism.As many protocols show a great similarity concerning connection establishment, maintenance and release, a start is made to model a Universal Protocol Subsystem.In addition to an informal description of the processes within the Universal Protocol Subsystem also a formal description will be given of most of these processes.Parallelism has been used where reasonable to perform a rate of data communication as high as possible.Multiple concurrent connections can be served in parallel.Transmission and reception of data can be performed in parallel.Processes can also operate in parallel if Protocol Data Units are pipelined through the Subsystem in analogue to pipelining within the Communication System.In analogue to multitasking on one CPU, multiple connections can be served by one Communication Entity quasiparallel.A global overview of the several processes and their mutual communications will be given.Also additional requirements on management of these processes and on memory will be described.8.2.2.I/0 Management and Memory Management ...... 74 8.2.3.Event Management and synchronisation .......... 74 8.2.4.Protection .........
