No to Java when Programming in Telecommunication WHY

[Neha Mohit]

hi, this might be the most stupid question ever asked on this forum.

why do we use C / C++ for programming( in telecommunication domain)
rather than Java , though things are simple in Java , i mean the
implementation of sockets and threads. Some C/C++ programmer say that it is the execution time which makes C/C++ a better option . But as far as i
know Cay Horstman in his book said it is a misconception that java is slower than C/C++. Then why dont people use Java as a programming language for network programming(in telecommunication domain) rather than C/C++




thanx in advance

Java is not slower than C++ in general beacuse you have to know what the program will do to compare execution speed of different languages/platforms and also know how the speed is important in that particular case.

There are many aplications where Java is slow or unsuitable. But there should be some good use for Java in telecommunication, too.

please tell me the situations ....

i agree with you , but what are they

Hava a look at OCAP, it is what Digital Cable Set-top boxes are being built on for the future.

so are there no more suggestions ... :roll:

only telco systems I worked on were written in Cobol...

Hi -

I think it's probably overgeneralizing to say "nobody uses Java in telecommunications", just as it's incorrect to say "everybody uses C/C++". I'm sure you'll find Telecom systems written in all kinds of languages - including Java (note the previous post about the author's experience with a COBOL telecom system!)

To say Java is "slow" (to categorically say *anything* is "fast" or "slow") is simply nonsense, without qualifying things a bit more. For example, a Java application with a good JIT might be just as fast (perhaps even faster) than an equivalent C++ executable. Or for another example, a JSP servelet will undoubtedly outperform a C++ CGI program each time, every time.

Here's a link you might find interesting:

I'm not sure whether those are systems you were speaking about, but all off the telecom products at http://www.disy.net/products.html are mainly written in Java, with just a thin layer in C/C++ to communicate with the hardware. (Disclaimer: it's the company I'm working for.)

Some telecomunication services such as SMS are developed using Java (JMS for SMS) technology. But I can't say the name of provider.

That you don't know any concrete implementation doesn't mean that they're not!
