The Internet is the best example of the internetworking of many data networks from different organizations.
There are many different network structures that IP can be used across to efficiently route messages, for example: There are three features that differentiate MANs from LANs or WANs: Data center networks also rely highly on TCP/IP for communication across machines.
Data center network topology plays a significant role in determining the level of failure resiliency, ease of incremental expansion, communication bandwidth and latency.
[3] In analogy to the improvements in the speed and capacity of digital computers, provided by advances in semiconductor technology and expressed in the bi-yearly doubling of transistor density, which is described empirically by Moore's law, the capacity and speed of telecommunications networks have followed similar advances, for similar reasons.
[4] This empirical law holds that the bandwidth of telecommunication networks doubles every 18 months, which has proven to be true since the 1970s.
