Design Patterns And The Development Of SNMP Network Management System

SNMP (Simple Network Management Protocol) is the most popular network management protocol in the TCP/IP networks, and nearly all the network devices such as servers, workstations, routers and switches support this protocol. So the network management system that supports SNMP becomes a necessary tool for the network administrators now.Design Patterns is a new theory in the OOP (object oriented program) field, and plays a more and more important role in the software development period. The theory abstracts the common problems in software development and gives out general solutions for them. Then when people meet the same problems they can solve them reference to it.This paper, based on the "Design Pattern" theory, analyzes the SNMP network management system and gives solutions to a lot of practical problems meted during the development period. Together with the practice of the development of the commercial software, this paper discusses 11 most common used design patterns and 3 main principles. And then, gives out an instruction about how to use design patterns in the software development. It supplies some valuable cases for the student of Design Patterns. What's more, because the solutions are all general ones, they can be applied in other communication software. This paper also introduced a JAVA technology based frame work for distributed network management, and it's believed to be helpful for the enhancement of the efficiency of the network management system.The theses are organized as follows: Section 1 introduces the back ground of the paper and compares VANLINK SNMP API with two famous merchial products.meanwhile,it also gives a survey of the authors job during the development of the software. Section2 talks about some basic knowledge about SNMP and...
