ABSTRACT NEST (network server tool) can be used to automatically generate code infrastructure for TCP-based network servers. It uses a specification language to describe client-server interaction and state transitions within the server. This specification language has some similarities to the compiler tools Lex and Yacc, and its design makes network server specification straightforward. One of the main features of NEST is that it can generate three different types of server from the same basic specification: process-based, threaded, and event-driven. Our performance results show that we can produce server code for all three models which is competitive with established, highly-tuned servers

    ABSTRACT: This paper presents a Java framework based on separation of concerns and code generation concepts that facilitates development of concurrency and I/O in servers. In this approach, the application is modeled by a graph whose vertices correspond to units of treatment connected by channels. It allows to build all kind of servers: multithreaded, single-process event-driven, staged event driven architecture, etc. without modification of the functional part. This architecture also permits to extend very easily an application, adding vertices and edges to the graph. The aim of our development tool is to improve programmer productivity and portability, decreasing development time, and reducing bugs or deadlock problems
