Using Underscores, Hyphens or CamelCase in Naming Standards
I’ve been considering a small but vital problem in naming conventions in Networking. Namely, the use of underscores and hyphens in object names and devices. It’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.
Scaling Virtual Appliances With Embrane
Embrane uses concepts of IP Flows to scale virtual appliances. Embrane does this by managing IP flows and then directing to other appliances, in effect creating what I would call a two tier load balancing.

VRRP. CARP. Open Standards and Royalties on LC Connectors
In which I look at CARP vs VRRP, the nature of open standards and closed source fibre optic connectors that you pay royalties on, but you probably don’t know about.
Merchant Silicon and Vendor Software – The Hype in 2012
The thing about merchant silicon is how far it has penetrated the network vendors. In fact, it’s getting difficult switches that don’t have the same Network Processor inside as any other vendor. Networking hardware is looking like servers hardware – glue some chips and then market the heck out of your pretty colours.

Short Answer is “It depends, but usually yes.” Long answer follows with a discussion of launch power, receiver sensitivity, and cable losses.

This week it’s just Greg and Ethan talking over a few topics. What was intended to be a quick half hour chat for the new year about Packet Pushers turned into a more than an hour on a whole range of topics that interest us, especially on independence and community. Some technical, some industry stuff and some about our own lives.

Network Diagrams: OmniGraffle Tip – Merging Shapes
In OmniGraffle, you often want to merge shapes together to create a single object, but you don’t want to lose resolution and you want them to scale properly. Grouping doesn’t help, but this does.
