Experiences with the integration of protocol software tools
1996
An analysis of a number of protocol software tools that are widely used in the development of communication protocols in the Finnish telecommunications industry is presented. To analyse the integrated use of these tools, a non-trivial application layer protocol with ACSE, ROSE and a simple presentation layer has been designed and implemented with the help of these software tools. Particular attention has been paid to compose a complete protocol implementation from the fragments produced with separate tools. Our observations clearly indicate that this integration is a major problem with the current practices.
Multi-pass execution of functional logic programs
1994
An operational semantics for functional logic programs is presented. In such programs functional terms provide for reduction of expressions, provided that they ground. The semantics is based on multi-pass evaluation techniques originally developed for attribute grammars. Program execution is divided into two phases: (1) construction of an incomplete proof tree, and (2) its decoration into a complete proof tree. The construction phase applies a modified SLD-resolution scheme, and the decoration phase a partial (multi-pass) traversal over the tree. The phase partition is generated by static analysis where data dependencies are extracted for the functional elements of the program. The method g…
IN service specification using the KANNEL language
1995
KANNEL is an application-oriented language for protocol engineering, with integrated support for all the main aspects of implementing typical communications software. Intelligent network services with distributed and interacting components share a number of central features with communications protocols, thus bringing in the possibility of applying protocol engineering techniques within the area of intelligent networking. To verify this view, the KANNEL language is applied to the specification of an intelligent calling card service. The specification includes both visual and textual notations of KANNEL.
Hypertext support for the information needs of software maintainers
2004
Making changes safely to programs requires program comprehension and satisfaction of the information needs of software maintainers. In this paper we provide insights into improving hypertext-based software maintenance support by analyzing those information needs. There exists a series of four earlier, detailed-level empirical studies on the information needs of professional C program maintainers. We focus on these studies, synthesize their results and determine sources from which the required information might be attained. An experimental research tool, the HyperSoft system, is used to demonstrate the satisfaction of information needs and the system is analytically evaluated against the nee…
