Abstract

TCP migration is an important and complex aspect of process migration, which is the foundation of dynamic load balancing. Single IP Address cluster offers a transparent view of a cluster of machines as if they were a single computer on the network. In such an environment, TCP migration can play a significant role for providing services seamlessly. In this paper, we propose a live migration mechanism using Net filter framework in which no modification to Linux kernel is required. The proposed plug-in module approach has the following advantages: flexibility-TCP migration functions may be loaded and unloaded dynamically, without node function interruption, TCP connections are kept alive while migration is taking place.
