Here is a recap of articles I posted in May to my blog at Netcordia:

• "How's the network running? More on SLAs" discusses Service Level Agreements (SLAs) based on network QoS.
• "Anti-spoofing filters" describes why organize should use anti-spoofing filters to exclude packets that have invalid source addresses.
• "Config Policy and Operational Data" provides another example for incorporating operational data with configurations for performing configuration compliance validation.
• "Calling All Devices - What's on the network?" looks at device discovery mechanisms.
