Virtualization of Network I/O on Modern Operating Systems

Network I/O in modern operating systems is an incomplete system. A program can easily exhaust link bandwidth and entire buffer pool, since current operating systems do not have mechanisms to arbitrate resource consumption of concurrent connections. Some operating systems have traffic control mechanisms, but, they are only used for static control by system administrators. Because these mechanisms are independently developed for each operating system, they are not compatible. Consequently, development of networking technology has been severely retarded. In this network age, network users and their applications are still unable to control their own traffic, even on their local host, let alone in the network.
