A third method to avoid network congestion is the explicit allocation of network resources to specific flows. One example of this is the use of Contention-Free Transmission Opportunities (CFTXOPs) in the ITU-T G.hn home networking standard. For the Internet, RFC 2914 addresses the subject of congestion control in detail. Network resilience

A network operating system (NOS) is a specialized operating system for a network device such as a router, switch or firewall.. Historically operating systems with networking capabilities were described as network operating systems, because they allowed personal computers (PCs) to participate in computer networks and shared file and printer access within a local area network (LAN).
The Networking and Information Technology Research and Development (NITRD) program consists of a group of U.S. federal agencies to research and develop information technology (IT) capabilities to empower Federal missions; support U.S. science, engineering, and technology leadership; and bolster U.S. economic competitiveness.
