Denise Fishburne discusses repeat problems in IP Multicast. Learn about the foundation protocols of Multicast and Cisco Press’ Multicast Video Mentor.
Excellent presentation. Exactly like she said, for many of network engineers, even for those with a lot of knowledge and experience, Multicast is the “big bad wolf”.

A few days ago I received a notification from SolarWinds that they released a free Network Config Generator software and I was invited to download and test it.
I give it a try and even if I’m more used to the old plain text files with configuration template, this software was a pleasant surprise. I recommend it especially for those how are new in business and are beginners with Cisco devices. This software can get you out from some troubles when you are configuring Cisco platforms.
I had the idea to make a video tutorial about how to use it, but then I found the 2 videos below created by SolarWinds which give you an overview about this software and then a short how-to use it:

And the how to guide:

Riverbed Technology Inc. today released two new models of its WAN optimization engine, the Steelhead appliance, which can now achieve network throughput speeds of up to 1Gbit/sec. over Ethernet or OC-12 connections.
The new appliance, the Steelhead 7050-L (low) and 7050-M (medium), are the first to use solid-state drives (SSD) instead of hard disk drives and offer larger memory configurations — 32GB/48GB of memory — than previous models. The appliances are aimed at backup consolidation for disaster recovery and business continuity.

“This is the first WAN optimization product built on SSD, which enables faster read/write speeds,” said Nik Roudam, director of product marketing at Riverbed.
The appliances also support 10Gbit/sec. Ethernet for appliance clustering or for fail-over purposes. Up to 25 appliances can be clustered together for a total of 12GB/sec. throughput, according to Roudam.
The Steelhead 7050-L and 7050-M can be configured with 14 or 28 160GB SSD drives respectively, and two hard disk drives, which act as logging disks.

HP shrink the data centers with their new launched “box”. This “box” is a containerized data center which price starts at about 600.000$ without the inside equipment. How useful and how many customers will attract HP with this product we will see in the future, but for now if you have enough money to spend on such thing, you can have your own datacenter in your backyard.
