A focussed and practical text suitable for a first course in Computer Networking. The author presents only the core aspects of the subject rather than getting weighed down with too much peripheral (and often complicating) detail. The author also takes a learn by doing' approach and the book is full of practical exercises which allow the reader to put into practice what they have just read.
