I add the results in a blog posts so we can see over years on which optimization technology we were betting in 2011.
Stephan, a colleague of mine, found the following documents digging through multiple pages of Cisco.com. The documents present a nice view of different QoS approaches and the most important information. Somehow like “cheatsheets”. They were helpful to us when need to implement QoS in some parts of the network that we administer. I hope they will help you as well.
Maybe you’re wondering why I’m adding them here, since the documents are already somewhere in Cisco.com. As you probably know, Cisco has constantly changing their website in the last months and a lot of documentation is misplaced in the Cisco.com sitemap. We already had problems finding all links, so I said why not share it here as they are already public made by Cisco.
You’ll find a Download button under each document, for PDF version and at the end of this post there is a Link to download all documents in an archive. If somebody needs only one document and has a poor Internet connection why to force them to download the full archive.
As said in the beginning, if you’d prefer, you download all QoS graphs in one archive.
Let me know your opinions on the above approach on QoS from Cisco. Is is accurate? Do you apply them in your organization weather for Campus, WAN, VPN or even Security?
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.
