Dynamic evolution of network management software by software hot-swapping

The computer communications world is very dynamic, requiring continual software updating for correction, perfection, and increased functionality. The problem addressed here is that of providing an evolutionary path for software that permits updating without disrupting the operation and management of the network. This problem is relevant to network management software which is also dynamic. For example SNMPv3 is not yet a standard and is not yet widely deployed. Its initial installations will need to be perfected as more experience is acquired. This paper examines a software hot-swapping solution to the problem, whereby management system software modules can be replaced dynamically without disrupting the management process. The paper also discusses application of the technique to a modular SNMPv3 system implemented in Java
