You may have heard about IT service management and ITIL being yesterday’s news, but the survey suggests you need to re-evaluate those rumors. The enduring value of ITSM credentials and practices have been championed by Gene Kim, one of the Godfathers of the DevOps world, who has said, “It is my firm belief that ITSM and the DevOps movement are not at odds. Quite to the contrary, they’re a perfect cultural match.”

The purpose of Interior Routing Protocols (IGP), and routing protocols more generally, is to advertise the existence of destination networks. All protocols then have some method of picking what they would consider to be the best path and maintain the information. By...

What is Network Time Protocol (NTP)? Well, it’s a network protocol used to synchronize clocks between computing systems over a packet switched network. It’s been around since the mid-1980s and was developed by David Mills at the University of Delaware; it is one of the oldest protocols still around on the Internet. NTP replaced other time synchronization technologies that didn’t have some capabilities to adjust time based on location of the time source or time server relative to the receiver or adjusting to the variation of delay found on typical data networks.

Precision Time Protocol (PTP) is a protocol designed to go beyond what Network Time Protocol (NTP) can offer relative to accuracy. PTP is IEEE standard 1588 that can give local computing systems accuracy within the sub-microsecond range (such as microsecond, nanosecond or picoseconds) whereas NTP is within milliseconds or longer. PTP standard was first released in 2002 and known as 1588-2002. In 2008, the IEEE released a revised standard for PTP, known as 1588-2008, that improved the accuracy and precision of the protocol. It is also known as PTPv2 and is not backward compatible with the older version. PTP was developed for packet based network for control and measurement systems.

Modern quality management and project management are complementary. They both emphasize customer satisfaction and the underlying belief that quality leads to customer satisfaction. The main objective in quality management is making sure that the project meets the needs it was originally created to meet—nothing more, nothing less. In other words, to ensure quality, you must meet the needs of the stakeholder.

The question of how a project manager working in a functional or matrix organizational structure gets team members to perform is asked in almost every project management class I have taught.

One size does not always fit all. At times there’s a need to run more than one routing protocol and have more than one routing domain: multivendor shops, migration from one protocol to another, scalability issues of a single protocol, political or personal preference, production versus test networks, mergers, and acquisitions.

Routers and switches make up the bulk of the network infrastructure and are vulnerable to attack. In a previous article, I talked about some of the different ways of hardening your network devices. In this blog, I’d like to specifically examine the routing protocols used on the major Cisco network operating systems.
