Distributed Path Computation with Intermediate Variables (DIV)
[attachment=24823]
PROJECT DESCRIPTION
PROBLEM DEFINITION
Distributed routing algorithms may give rise to transient loops during path re-computation, which can pose significant stability problems in high-speed networks. In particular it can severely impact network performance, especially in networks with no or limited loop mitigation mechanisms. In the presence of a routing loop, a packet caught in the loop comes back to the same nodes repeatedly, thereby artificially increasing the traffic load. The emergence of a routing loop then often triggers network-wide congestion, which can lead to the dropping or delaying of the very same control (update) packets that are needed to terminate the loop; thereby creating a situation where a transient problem has a lasting effect.
SOFTWARE FEATURES
Java
Java is an object-oriented multithread programming languages .It is designed to be small, simple and portable across different platforms as well as operating systems.The following figure shows the working of java.
Simple And Powerful
Java was designed to be easy for the professional programmer to learn and use efficiently. Java makes itself simple by not having surprising features. Since it exposes the inner working of a machine, the programmer can perform his desired actions without fear. Unlike other programming systems that provide dozens of complicated ways to perform a simple task, Java provides a small number of clear ways to achieve a given task.
Secure
Today everyone is worried about safety and security. People feel that conducting commerce over the Internet is a safe as printing the credit card number on the first page of a Newspaper. Threatening of viruses and system hackers also exists. To overcome all these fears java has safety and security as its key design principle.
Using Java Compatible Browser, anyone can safely download java applets without the fear of viral infection or malicious intent. Java achieves this protection by confining a java program to the java execution environment and by making it inaccessible to other parts of the computer. We can download applets with confidence that no harm will be done and no security will be breached.
Portable
In java, the same mechanism that gives security also helps in portability. Many types of computers and operating systems are in use throughout the world and are connected to the internet. For downloading programs through different platforms connected to the internet, some portable, executable code is needed. Java’s answer to these problems is its well designed architecture.
Object-Oriented
Java was designed to be source-code compatible with any other language. Java team gave a clean, usable, realistic approach to objects. The object model in java is simple and easy to extend, while simple types, such as integers, are kept as high-performance non -objects.
Dynamic
Java programs carry with them extensive amounts of run-time information that is used to verify and resolve accesses to objects at run-time. Using this concept it is possible to dynamically link code. Dynamic property of java adds strength to the applet environment, in which small fragments of byte code may be dynamically updated on a running system.
