In modern protocol design, protocols are "layered" according to the OSI 7 layer model or a similar layered model. Layering is a design principle that divides the protocol design into many smaller parts, each part accomplishing a particular sub-task and interacting with the other parts of the ...
To understand Layer 2 network protocols, we must learn about the Open Systems Interconnection (OSI) model and Layer 2 first. Touted as the data link layer, Layer 2 is the second of the seven-level OSI model that is responsible for error-free data transmission between devices in the same ne...
Network protocols break larger processes into discrete, narrowly defined functions and tasks across every level of the network. In the standard model, known as the Open Systems Interconnection (OSI) model, one or more network protocols govern activities at each layer in the telecommunication exchange....
While network protocols provide a unified method for communication, network standards govern the hardware and software that use them. Today, there are hundreds of thousands of hardware suppliers. Yet all of their technology seamlessly integrates with your computer or network with minimal effort. Networ...
By setting network types for OSPF interfaces and adjusting the OSPF attributes, you can flexibly build OSPF networks. In Table 5-20, OSPF classifies networks into four types based on the types of link layer protocols. Table 5-20 Network types supported by OSPF Network Type Cha...
A VPN comes along with security protocols. The VPN protocol implements a set of instruction for exchanging messages on a public network with proper assurance. VPN works with different protocols that depend on different network layers. VPN Protocols makes
Network Protocols and Routing: WANs employ routing protocols, such as Border Gateway Protocol (BGP), to efficiently direct data packets across multiple interconnected networks and determine the best path. Quality of Service (QoS): WANs often implement QoS mechanisms to prioritize certain types of traf...
A bridge operates at Layer 2 of the OSI model. Compare the common types of network devices. 3. Gateway A gateway is anetwork nodethat connects discrete networks or systems that use different protocols, enabling data to flow between the networks. Gateways use multiple protocols and translate an...
Network architecture understood as the set of layers and layer protocols that constitute the communication system.
