Very usefull book for those who wants to know how is the Internet coonction working through all layers of OSI model. Good basics for F5 engineers as well.
The book is cutting it short and straight forward towards getting started with F5 products. There are so much good informations here regarding networks fundamentals and security (Comming from Cisco background) also introducing in a smooth way the BigIP world. However the presentation of the BigIP products could have been better but I presume that the author wanted to keep it as simple as possible.
