Advanced QoS for multi-service IP/MPLS networks / Ram Balakrishnan, Wiley, 2008

If you are in telecom, planning networks, you will find this book very useful. Otherwise, it will be ‘tough sledding’.

The internet backbones used to be ‘best-effort’ so that if someone was bulk-copying some video files then someone else on a VOIP call would get broken up voice quality. Quality of Service (QoS) attempts to fix that problem by prioritizing traffic or ‘bandwidth shaping’. Unfortunately, it can also be put to competitive use, for example when a business provides a video service and an internet access service, and the latter has video throttling (though this book does not talk about such issues).
