    Nagios System and Network Monitoring

    It’s ten o’clock on Monday morning. The boss of the branch office is in a rage. He’s been waiting for hours for an important e-mail, and it still hasn’t arrived. It can only be the fault of the mail server; it’s probably hung yet again. But a quick check of the computer shows that no mails have got stuck in the queue there, and there’s no mention either in the log file that a mail from the sender in question has arrived. So...

    Packet Guide to Voice over IP

    A short while ago, as network engineers made plans for the future, one of the considerations was the eventuality of Voice over the Internet Protocol, or VoIP. For several years, VoIP was always “on the horizon” or “around the corner,” as many believed that it was coming but were unsure about the timing. The question was whether network designers and educational programs should become early adopters, building in capacity and knowledge...

  • HTTP The Definitive guide

    HTTP The Definitive guide

    The Hypertext Transfer Protocol (HTTP) is the protocol programs use to communicate over the World Wide Web. There are many applications of HTTP, but HTTP is most famous for two-way conversation between web browsers and web servers. HTTP began as a simple protocol, so you might think there really isn’t that much to say about it. And yet here you stand, with a two-pound book in your hands. If you’re wondering how we could have written 650...

  • Configuring Cisco Unified Communications Manager and Unity Connection: A Step-by-Step Guide

    Configuring Cisco Unified Communications Manager and Unity Connection: A Step-by-Step Guide

    On March 10, 1876, Alexander Graham Bell made the first successful telephone call. As with many things, the test was purely accidental. Graham spilled acid on his leg, and Watson, his assistant, heard his call for help through the telephone. So, what has changed over the last 129 years? It would be easier to discuss what hasn’t changed. The world of telephony has undergone some significant changes but none as exciting as Voice over IP (VoIP)...

    Cisco Unified Contact Center Enterprise (UCCE)

    With all the fantastic Cisco documentation available online, why does the world of UCCE need this book? UCCE is such a big topic that it would be easy to think that it is possible to try and cover absolutely everything. Unfortunately, this would turn this book into nothing more than a product reference manual that could potentially be out of date as soon as a new UCCE software version became available. I also feel that I would potentially end...

  • Ethernet Switches

    Ethernet Switches

    Ethernet switches, also known as bridges, are basic building blocks of networks, and are so commonly used that you may not give them a second thought. It’s possible to build networks without knowing very much about how switches work. However, when you build larger network systems, it helps to understand both what goes on inside a switch and how the standards make it possible for switches to work together.
