Experiences in Using SDL to Support the Design and Implementation of a Logical Link Layer Protocol [chapter]

Laila Daniel, Matti Luukkainen, Markku Kojo
2005 Lecture Notes in Computer Science  
The protocol was modeled in SDL and successive refinements of its design were carried out based on feedback obtained from using the validation facilities of Telelogic Tau 4.4 SDT.  ...  We have used SDL to support the design and implementation of SLACP, a novel logical link layer protocol to enhance the performance of TCP over wireless WAN links.  ...  Validation of SLACP Using SDL Telelogic Tau 4.4 SDT tool is used for validating SLACP. We formulate the following validation scenarios which represent the protocol operations.  ...

Specification-driven Performance Monitoring of SDL/MSC-specified Protocols [chapter]

P. Dauphin, W. Dulz, F. Lemmen
1996 Protocol Test Systems VIII  
A prototype tool called MISS was developed to proof the suitability and practicability of the method.  ...  The basic idea is to apply MSCs in order to concentrate on the main parts of interacting SDL processes such as signal exchanges and timeouts.  ...  The selection of the method depends on the SDUMSC CAPE tool used. Because we built the MISS prototype in conjunction with SDT (SDL Design Tool) [TeI93] the third method was appropriate.  ...
