A Few Principles We have a transmitter, a receiver and transmission media. Information flows from two entities over a channel. We can have broadcast or point- to-point.

Intercommunications Differing inputs signals. Differing transmission media and transmission rates. Different addressing methods: eg IP address and Telephone Number. Different Quality of Service (QoS) requirements ... fast or reliable?

Every increasing demand ... Ever increasing requirement for network capacity. Every increasing reliance for “always- on” and “always available” network connection. Number of devices connecting increases by the day.

Communication Media Many different types of media ... radio ... electrical signals ... light pulses.

Differing transmission rate The speed of a connection typically measured in the amount of bits that can be sent per second (bps). Media differs in its capacity.

Network convergence Fusion of many different information sources into a digital communication network.

Network convergence ... differing requirements Communication channel has many different aspects. Inc support for legacy systems.

Network convergence ... differing requirements Different types of traffic have different needs (Quality of Service – Latency (the delay in the transmission channel) v Error sensitivity.

Ever Increasing Demand Increasing hosts connecting. Increasing services ... games ... TV ... e- Commerce ... Cloud ...
