Network Topology
Topology describes the physical or logical structure of the network.
- in terms of nodes and links
- physical topology describes the placement of nodes and how they are connected by the transmission media
- logical topology describes the flow of data through the network
- point to point link is a single link between two nodes
- guaranteed a level of bandwidth
- because the connection is shared by only two devices
- can be physical or logical
- E.g.
- on a WAN, two router appliances might be physically linked via multiple intermediate networks and physical devices but share a logical point to point link, where each can address only the other router
- E.g.
- the 1:1 relationship defines a point to point link
- guaranteed a level of bandwidth
