A modular switch or chassis switch is a type of network switch which can be configured using field-replaceable units. These units, often referred to as blades, can add more ports, bandwidth, and capabilities to a switch. [1] These blades can be heterogenous, and this allows for a network based on multiple different protocols and cable types.
For example, the sample diagram does not indicate the physical type of connection between the PCs and the switch, but since a modern LAN is depicted, Ethernet may be assumed. If the same style of line was used in a WAN (wide area network) diagram, however, it may indicate a different type of connection.
A LAG is a method of inverse multiplexing over multiple Ethernet links, thereby increasing bandwidth and providing redundancy. It is defined by the IEEE 802.1AX-2008 standard, which states, "Link Aggregation allows one or more links to be aggregated together to form a Link Aggregation Group, such that a MAC client can treat the Link Aggregation Group as if it were a single link."
Network documentation is a form of technical documentation, the goal of which is to maintain computer networks. [1] It contains information about how the network is built, how it should perform, and where to troubleshoot problems. The purpose of network documentation is to keep networks running as smoothly as possible while minimizing downtime ...
Broadly, there are four types of tools that help create network maps and diagrams: Hybrid tools; Network Mapping tools; Network Monitoring tools; Drawing tools; Network mapping and drawing software support IT systems managers to understand the hardware and software services on a network and how they are interconnected. Network maps and diagrams ...
There are a number of specific classifications but all lie on a continuum between the dumb network (e.g. the Internet) and the intelligent network (e.g. the PSTN). A popular example of such usage of the term in distributed applications, as well as permanent virtual circuits, is the organization of nodes in peer-to-peer (P2P) services and networks.
The main advantage of layer-3 switches is the potential for lower network latency as a packet can be routed without making extra network hops to a router. For example, connecting two distinct segments (e.g. VLANs) with a router to a standard layer-2 switch requires passing the frame to the switch (first L2 hop), then to the router (second L2 ...
A cell 0 is the basic unit and building block of DCell topology arranged in multiple levels, where a higher level cell contains multiple lower layer cells. The cell 0 is building block of DCell topology, which contains n servers and one commodity network switch. The network switch is only used to connect the server within a cell 0.
