TCP/IP The protocol is routable, which means that data packets can be switched (routed to a different subnet) by use of the packet's destination address. TCP/IP's ability to be routed allows greater fault tolerance. If a network failure occurs, packets are transported by a different route.

ring topology Definition. Network cabling scheme in which one cable sequentially connects all nodes and forms a closed loop. A data packet starting from the originating node is examined by the next active node if it is addressed to that node. If it does, it is copied, otherwise it is regenerated and passed on to the next node until it reaches back the originating node and is discarded. The ability to regenerate data packets allows a ring topology to span far greater distance than bus or star topologies.

Circuit switching Circuit switching is a methodology of implementing a telecommunications network in which two network nodes establish a dedicated communications channel (circuit) through the network before the nodes may communicate.hile circuit switching is commonly used for connecting voice circuits, the concept of a dedicated path persisting between two communicating parties or nodes can be extended to signal content other than voice.

Routing protocol A routing protocol specifies how routers communicate with each other, disseminating information that enables them to select routes between any two nodes on a computer network.Routing algorithms determine the specific choice of route. Exterior gateway protocols are routing protocols used on the Internet for exchanging routing information between Autonomous Systems, such as Border Gateway Protocol (BGP), Path Vector Routing Protocol.

NITL files petition with Surface Transportation Board, calling for new reciprocal switching rules By definition, reciprocal switching is “an interchange of inbound and outbound carload freight among railroads in which the cars are switched by one railroad to or from the siding of another under a regular switching charge that is usually absorbed by the carrier receiving the line-haul.”.

Switch Definition - What does Switch mean? A switch, in the context of networking is a high-speed device that receives incoming data packets and redirects them to their destination on a local area network (LAN). A LAN switch operates at the data link layer (Layer 2) or the network layer of the OSI Model and, as such it can support all types of packet protocols.

Security Both MPLS and tag switching have a data plane that forwards packets based on fixed length labels. They also have a control plane that deals with label assignment and distribution between the devices based on the Forward Equivalence Class (FEC).

What is a packet? For example, every Web page that you receive comes as a series of packets, and every e-mail you send leaves as a series of packets. Networks that ship data around in small packets are called packet switched networks.On the Internet, the network breaks an e-mail message into parts of a certain size in bytes.These are the packets.ach packet is then sent off to its destination by the best available route -- a route that might be taken by all the other packets in the message or by none of the other packets in the message. This makes the network more efficient.

Routing protocol It could also mean a specific RFC-described protocol (see: Exterior Gateway Protocol). Many routing protocols are defined in documents called RFCs. Some versions of the Open System Interconnection (OSI) networking model distinguish routing protocols in a special sublayer of the Network Layer (Layer 3). Exterior gateway protocols are routing protocols used on the Internet for exchanging routing information between Autonomous Systems, such as Border Gateway Protocol (BGP), Path Vector Routing Protocol.

Packet Packet. A term first coined by Donald Davies in 1965, a packet is a segment of data sent from one computer or device to another over a network. A packet contains the source, destination, size, type, data, and other useful information that helps packet get to its destination and read.Below is a breakdown of a TCP packet. When a packet is transmitted over a network, network routers and switches examine the packet and its source to help direct is direction. 2  During its transmission, network packets can be dropped. 3  If a packet is not received or an error occurs, it is sent again.

How network works - Network switches and broadcast packets. How network works - Network switches and broadcast packets. Network switches - A network switch is an Ethernet device that can divided an Ethernet network up in different zones. Within one zone all computers will se each others traffic but outside the zone only traffic that is aimed for computer in that zone is transferred.

- Vocabulary. 1  Packets - Small chunks of information that have been carefully formed from larger chunks of information. 2  TCP - Transmission Control Protocol - provides reliable, ordered, and error-checked delivery of a stream of packets on the internet. TCP is tightly linked with IP and usually seen as TCP/IP in writing.

How Does Load Balancing Work? The term 'new traffic' corresponds to a single packet or an entire flow to a destination, depending on the type of switching configured. For process-switching—load balancing is on a per-packet basis and the asterisk (*) points to the interface over which the next packet is sent.

TCP/IP TCP/IP. Short for Transmission Control Protocol/Internet Protocol, TCP/IP is a set of rules (protocols) governing communications among all computers on the Internet. More specifically, TCP/IP dictates how information should be packaged (turned into bundles of information called packets), sent, and received, as well as how to get to its destination.

Cut-through switching Compared to store and forward, this technique reduces latency through the switch and relies on the destination devices for error handling. Pure cut-through switching is only possible when the speed of the outgoing interface is equal to or greater than the incoming interface speed.

Code-switching Thus, code-switching is the use of more than one linguistic variety in a manner consistent with the syntax and phonology of each variety. Code-switching is distinct from other language contact phenomena, such as borrowing, pidgins and creoles, loan translation (calques) , and language transfer (language interference).peakers form and establish a pidgin language when two or more speakers who do not speak a common language form an intermediate, third language. On the other hand, speakers practice code-switching when they are each fluent in both languages.

Computer network Computer communications links that do not support packets, such as traditional point-to-point telecommunications links, simply transmit data as a bit stream. When data is formatted into packets, the bandwidth of the communication medium can be better shared among users than if the network were circuit switched.

What is Layer 2 Switching loop What is Layer 2 Switching loop. In practical Local Area Networking, it is common that the switches are interconnected for redundancy. When switches are interconnected, the network will not fail completely even one if the connected link fails. When switches are interconnected for redundancy as shown below, another serious network problem can occur, which is known as Layer 2 Switching loop. The Layer 2 traffic can be classified as unicast (one to one), multicast (one to many), and broadcast (one to all).
