Introduction to Rfc (Request For Comments):-

A Request for Comments (RFC) is a type of publication of the Internet Engineering Task Force (IETF) and the Internet Society, the main technical development and standardization bodies for the Internet. A RFC is written by engineers and computer scientists in the form of a memorandum describe methods, behavior, research or innovations are applicable to the operation of the internet and systems connected to the

Secure Copy or SCP is a means of securely transferring computer files between a local host and a remote host or between two remote hosts. It is based on the Secure Shell (SSH) protocol. “SCP” generally refers to: • Secure Copy Protocol • Secure Copy (remote file copy program) • Secure Copy Protocol The

In computer networks, the Stream Control Transmission Protocol (SCTP) is a transport-layer protocol (protocol number 132 [1]), which in a similar role in the popular protocols Transmission Control Protocol (TCP) and User Datagram Protocol (UDP). It offers some of the same service characteristics of both: it is message-oriented as UDP and ensures reliable, in-sequence transport of messages with congestion control like TCP. The IETF

Packet switching is the approach of a number of computer network protocols to deliver data across a local or long-distance connection. Examples of packet switching protocols are Frame Relay, IP and X.25.

How Packet Switching Works

Packet switching keeps packaging data in specially formatted units (called packets) that are typically routed from source to destination using network switches and routers.

Each packet contains the address

Virtualized network functions or VMFS are the software realizations of the various network functions that can be deployed in a network Functions Virtualization Infrastructure and needed to run the network. For example, a virtual network function or VNF is processing a specific network function to be performed on one or more virtual machines on top of the hardware network infrastructure. The individual virtual network functions

Synchronous Ethernet (synce) is largely created as a solution to two challenges of telecom operators. In the first place, as the demand for broadband services has increased operators needed a way to ensure that they can provide the extra traffic (mostly from bandwidth-intensive applications such as broadcast TV, video on demand and IPTV) at a low enough find cost- per-bit to ensure they are profitable. In the second place, has led to

Proxy servers act as an intermediary between the two ends of a client / server network. Proxy servers interface network applications, most Web browsers and servers. Inside business networks, proxy servers are installed in specially designated internal (intranet) devices. Some Internet Service Providers (ISPs) also use proxy servers as part of providing online services to their customers. Finally, a third category of

Ethernet was developed at Xerox PARC between 1973 and 1974. It was inspired by ALOHANET which Robert Metcalfe had studied as part of his doctoral thesis. The idea was first documented in a memo that Metcalfe wrote on May 22, 1973, where he named it after the refuted luminous ether as a “ubiquitous, completely passive medium for the propagation of electromagnetic waves.” In 1975, Xerox filed a patent application listing Metcalfe

In wireless communications, the term “Hz” (the 19th century scientist’s name was Hertz Hertz) refers to the transmission frequency of radio signals in cycles per second:

• 1 Hz is equal to one cycle per second • For 1 MHz (megahertz) equals one million cycles per second (ie one million hertz) • 1 gigahertz (GHz) equals one billion times per second
