Software-defined networking (SDN) is an approach to network management that uses abstraction to enable dynamic and programmatically efficient network configuration to create grouping and segmentation while improving network performance and monitoring in a manner more akin to cloud computing than to traditional network management. [1]
In comparison, several networking models have sought to create an intellectual framework for clarifying networking concepts and activities, [citation needed] but none have been as successful as the OSI reference model in becoming the standard model for discussing and teaching networking in the field of information technology.
A supernetwork, or supernet, is an Internet Protocol (IP) network that is formed by aggregation of multiple networks (or subnets) into a larger network. The new routing prefix for the aggregate network represents the constituent networks in a single routing table entry.
An ATM network interface in the form of an accessory card. A lot of network interfaces are built-in. A network interface controller (NIC) is computer hardware that connects the computer to the network media and has the ability to process low-level network information. For example, the NIC may have a connector for plugging in a cable, or an ...
In some cases, modifications of the network packet may be necessary while routing, in which cases checksums are recalculated. Hop limit Under fault conditions, packets can end up traversing a closed circuit. If nothing was done, eventually the number of packets circulating would build up until the network was congested to the point of failure.
Very generally, most of communications can be divided into connection-oriented, and connectionless.Whether a communication is connection-oriented or connectionless, is defined by the communication protocol, and not by application programming interface (API).
Overlay network diagram for a structured P2P network, using a distributed hash table (DHT) to identify and locate nodes/resources In structured peer-to-peer networks the overlay is organized into a specific topology, and the protocol ensures that any node can efficiently [ 28 ] search the network for a file/resource, even if the resource is ...
Simple Network Management Protocol (SNMP) is an Internet Standard protocol for collecting and organizing information about managed devices on IP networks and for modifying that information to change device behavior.
