Overview of Network Devices and Routing Algorithms
Network Devices (Hub, Repeater, Bridge, Switch, Router and Gateways)
- Repeater – A repeater operates at the physical layer. It regenerates the signal over the same network before the signal gets too weak or corrupted. This extends the length to which the signal can be transmitted over the same network. It is a 2 port device.
- Hub – A hub connects multiple wires coming from different branches. Hubs cannot filter data, so data packets are sent to all connected devices. Sometimes this results in data wastage also. A hub is a multiport repeater.
- Bridge – A bridge operates at data link layer. It is a kind of repeater, equipped with functionality of filtering content by reading the MAC addresses of source and destination. It has a single input and single output port. Hence it is a 2 port device.
- Switch – Switch is again a data link layer device. A switch is a multi port bridge with a buffer and a design that can boost its efficiency and performance. Switch can perform error checking before forwarding data.
- Routers – Router is mainly a Network Layer device. A router is a device like a switch that routes data packets based on their IP addresses. Routers normally connect LANs and WANs together and have a dynamically updating routing table based on which they make decisions on routing the data packets. Router divide broadcast domains of hosts connected through it.
- Gateway – Gateways can operate at any network layer. A gateway is like a passage to connect two networks together that may work upon different networking models. They basically works as the messenger agents that take data from one system, interpret it, and transfer it to another system. Gateways are in general, more complex than switch or router.
A Routing Algorithm is a method for determining the routing of packets in a node. For each node of a network, the algorithm determines a routing table, which in each destination, matches an output line. The algorithm should lead to a consistent routing, that is to say without loop. This means that you should not route a packet to another node that could send back the package.
There are three main types of routing algorithms:
• Distance Vector (distance-vector routing);
• To link state (link state routing);
• Path to vector (path-vector routing).
