bandwidth-delay
The path bandwidth. A cumulative interface delay. The reliability between source and destination The load on a link in bits per second. The MTU value of a path.
high bandwidth link has high quality content and it is large in size
How many bits are there in a data link layer ethernet address?
16 bits per block
16 bits per block
the bandwidth and the signal to noise ratio
Bits of it, yes; bits of it, no. I am attaching a link to my website so you can see pictures.
Enhanced Interior Gateway Protocol It is a Cisco proprietary protocol. It uses bandwidth and delay by default to calculate the best path. It can also use load and delay, but these are usually not used. It is a distance vector routing protocol. It keeps a topology map, but it is only similar to the topology map of link state routing protocols.
Since the basic PSTN (plain old telephone network) network link supports 64 Kbps bandwidth, I would say that is your answer.
A simple search of the net will find there are many bandwidth monitoring sites that are available for free. A popular one is callled Free Meter Bandwidth Meter. You also can use WFilter freeware for network bandwidth monitoring.
The component of the SPF algorithm that is inversely proportional to bandwidth is the cost metric assigned to each link. Lower bandwidth links are assigned higher cost metrics, which indicates that it is more costly to traverse those links in terms of bandwidth consumption.
