Hunting down bots on your network
"Bots are really tough to keep track off. Their Achilles heel has always been their bi-directional communication with a command and control server somewhere. I am a big believer in mining and correlating your current data to find answers on your network. With that in mind, I have been running the program Bot Hunter for a while now...a free program for tracking bots on your network that uses the Snort 2 correlation engine," Jimmy Ray Purser writes in his Networking Geek to Geek blog.

Michael Morris From the Field: The Cisco QuantumFlow Processor - The Engine in the ASR 1000 Series
Several weeks ago I wrote a couple blogs on the Cisco ASR 1000-series routers: so its a good time to review the Cisco QuantumFlow Processor (QFP), the engine in the ASR 1000-series. To be put simply, the Cisco QuantumFlow Processor (QFP) is everything on a chip.

Wendell Odom's Cisco Cert Zone: All about OSPF – an index of three months of OSPF training posts
Here is a list that indexes all of the OSPF posts over the last three months. I'll move on to the next topic before the week's up - a CCNA lab/ CCNP lab re-examination.

Dennis Hartmann on Cisco Unified Communications: Cisco QoS: Link Fragmentation and Interleaving
The goal of LFI is to lower serialization delay on slow speed links. Serialization delay is the amount of time it takes a router to serialize a packet onto a WAN link. The goal of LFI is to ensure serialization delay never takes more than 10ms.

Kamal Vyas: Next Gen Data Center: Fabric Extender - Extended Virtual Chassis ... very FEXY!
When looking at end-to-end Nexus DC design and Nexus 7K vPC , one of the prominent CPOC test components is FEX (Fabric Extender) module. The best way to describe FEX would be a (remote) line card hanging off a Cisco Nexus 5000 switch. (Cisco Subnet extends a welcome to Kamal Vyas as our newest blogger. Vyas is a lead Data Center Network Design Engineer at a $3.5 billion high-tech company.)
