....and TCP [Braun95b] Castel94] protocols showed that user level software implementations can perform as well as kernel tuned TCP, while still keeping the flexibility of configurable software. Performance enhancements to the ASN.1 encoding facilitate the implementation of a presentation filter [Dabbous92]. Multiple communication services including group communication and variable error control have been studied for a variety of applications (e.g. multimedia vi ALFred, an ALF ILP Protocol Compiler for Distributed Application Automated Design. 9 deo conferences with shared workspace, mobile ....

New applications (e.g. audio and video conferencing, shared white board, supercomputer visualization etc. with specific communication requirements are being considered. Depending on the application, these requirements may be one or ....
....we present performance test results of our prototype XTP. Performance of a kernel TCP BSD implementation will also be presented. The figures should be taken very carefully: the performance of a protocol depends on the environment, implementation tunings and enhancement technique as demonstrated in [7]. Many differences exist between the choices we adopted and the TCP kernel implementation, and the XTP implementation is not as well tuned as the TCP kernel implementation. Therefore, it is not meaningful to make precise comparison of both protocols based on the performance figures we have. ....

....3.1 Introduction In this we present results of performance tests of both prototype implementation of XTP and kernel implementation of TCP. The figures should be taken very carefully: the performance of a protocol depends on implementation tunings and enhancement technique as demonstrated in [14], and the XTP implementation is not as well tuned as the TCP kernel implementation. Thus, it is not meaningful to make precise comparison of both protocols based on the performance figures we have. However, the figures gives an idea on the possible performance of XTP when implemented in the user ....

.... (e.g. XTP [PEI92] At the presentation level, this concerns the performance optimization of the presentation coding and decoding routines either by defining new light weight transfer syntaxes [Hui90] or by implementation enhancements of the standard ASN.1 Basic Encoding Rules (BER) routines [Dab92], Hui92] Lin93] Good implementation techniques represent one of the most important factors in determining the performance of a given protocol [Cla89] These techniques depend on the environment more than on the protocol itself. The proposed solutions focused on the enhancement of the protocol ....
