It&#8217;s a hot topic for argument when the time comes for corporate standards (and when Network Engineers have beverages in  a public house). Now, I figure that there are three possible grammar options for making names - hyphens, underscore and CamelCase.]]></description>

		<description><![CDATA[These all suggest that the time for planning and designing Service Modules is over. There are no suggestions that service modules for the Nexus 7000 will be developed that I can see. I can prognosticate that it would slow down the development of the core switch / route / performance functions, and it will be some years before those core capabilities is complete enough that service modules would become viable product development tasks &#8212; they might be in development, but not much chance of going into production. [^1]

Do I sound bitter about Service Modules ? A bit. I've had a number of hard to solve problems that lasted months before code fixes arrived. I've been fan of the NAM but the price is now far removed from it's practical value. USD$30K List is way over priced for its capabilities and even with a 30% discount, you can buy a lot of network management systems that deliver much better functions and features for that price.]]></description>
