TCP/IP .NET Sockets FAQ. This is an attempt to address some TCP/IP frequently asked questions and present best practices.


While the WinSock Programmer’s FAQ will remain the ultimate FAQ for native code, there is a growing need for a simplified version that addresses the managed interface to TCP/IP sockets. Section 1 - Application Protocol Design 1.1 - Message framing, also known as: “One side sent X bytes, but the other side only got Y bytes.” “One side sent several packets, but the other side only got one packet, which was all the sent packets appended together.” “I need the function that will send exactly one packet of data.” 1.2 - Detection of half-open (dropped) connections, also known as: “My socket doesn’t detect a lost connection; it just sits there forever waiting for more data to arrive.” 1.3 - Application Protocol Specifications 1.4 - XML over TCP/IP Section 2 - Socket Class 2.1 - Socket operations 2.2 - Error handling 2.3 - Using Socket as a client socket 2.4 - Using Socket as a server (listening) socket.

Network management. In computer networks, network management refers to the activities, methods, procedures, and tools that pertain to the operation, administration, maintenance, and provisioning of networked systems.[1] Network management is essential to command and control practices and is generally carried out of a network operations center.

Network management

Operation deals with keeping the network (and the services that the network provides) up and running smoothly. It includes monitoring the network to spot problems as soon as possible, ideally before users are affected.Administration deals with keeping track of resources in the network and how they are assigned. It includes all the "housekeeping" that is necessary to keep the network under control.Maintenance is concerned with performing repairs and upgrades—for example, when equipment must be replaced, when a router needs a patch for an operating system image, when a new switch is added to a network.

Note: Network management does not include user terminal equipment. RFC INDEX. Protocol Registries. IANA is responsible for maintaining many of the codes and numbers contained in a variety of Internet protocols, enumerated below.

Protocol Registries

We provide this service in coordination with the Internet Engineering Task Force (IETF). For more information on how to create registries, please see RFC 5226, Section 4. This document also covers the requirements for IANA Considerations in RFCs. To view the various protocol registries, just click on their titles. To apply to modify a registry, use the relevant form.
