Cisco’s been doing virtualization in various forms on the network side for quite a long time. One incredibly powerful feature that I think is still amazingly under utilized is the Cisco VSS or Virtual Switching System.
The ability to make two 6500′s look like a single switch so that you can have your cake and eat it too. Its the epitome of giving us the redundancy and availability we need while simultaneously allowing us to use the extra capacity that could normally sit unused. Easier management and configuration make this a no-brainer that more network managers should consider as ‘required’ in their design. Check out our ‘Fundamentals of VSS‘ to get yourself started.
Dateline Barcelona, Catalonia, Spain. Citrix Summit and Synergy, October 2011
Last post I said I’d get back to you to give you, at least, my opinion of why Citrix and Cisco are partnering up. As you might have seen from the dateline above, it’s easy to find out when you get to Citrix Summit and Synergy. It has to do with the global and ubiquitous Cisco networks deployed by organizations everywhere. Citrix is doing great with XenApp (last I heard, well over 50,000,000 licenses) and is poised to do even better with XenDesktop.
So, in my last blog, I pointed out that Manufacturers, and particularly car makers, will be driving the Internet of Things (IoT) by incorporating standard networks into their machines. I also indicated that evolving the standards is going to be critical to that adoption.
Applying standard networks (by that I mean Ethernet, IP, TCP/UDP, 802.11/WiFi, etc.) machines is going to be a distinctly different than the networking of computers, phones and the plethora of tablets and handheld devices that has driven the Internet and standard networks to date. Read More »

As you know, the Society of Cable Telecommunications Engineers (SCTE) continues to strive to provide new and unique ways to both train and challenge the cable workforce and our members. Through our Chapters, we have been holding a very successful Olympic-style challenge for field-level employees that includes both hands-on skill assessments and knowledge-based contests, and this continues to be a big hit with our members and the industry. But one thing I kept hearing in meetings with cable executives, managers and at SCTE chapters was the need for SCTE to provide resources and involvement opportunities for the IP engineers and computer scientists in our workforce who manage an increasingly larger portion of the overall network.
I’m therefore proud and excited to announce the new SCTE IP Challenge that we developed in partnership with Cisco as a response to this need. This new interactive event was created to drive awareness of the importance of foundational IP knowledge among the cable workforce, and it is designed to promote the benefits of IP expertise in the cable industry, as well as leverage thought leadership around IPv6 in particular.

The explosion of media traffic and video applications calls for a foundation network that is ready to provide intelligent priority-based services for them, and one cannot agree more with the paramount role of QoS in deployment of medianets. QoS Technologies have traditionally helped administrators exert control over network behavior with differential treatment of various traffic classes, and this becomes a much more compelling requirement in today’s landscape with a lot of low latency and delay sensitive traffic consuming a big part of the total available bandwidth pool.
Many of you would nod in agreement when we talk about the complexities involved in QoS deployment. The complexities stem from a plethora of reasons: platform inconsistencies in provisioning and feature sets, divergent hardware capabilities across product lines, lack of a centric management application to provision and manage QoS etc.
In order to alleviate these pain points, we have the pleasure of introducing a series of QoS-Simplified AAGs (At-A-Glance) documents especially as an aid to expedite Medianet QoS deployments. The goal of this AAG series is to drive QoS Simplification, enable an administrator to understand and configure campus QoS features like Trust, Per-Port/Per-VLAN support, ingress/egress QoS features and Auto QoS, use QoS effectively in WAN/VPN deployments and to provide a CLI quick start guide for beach head platforms like cat3k, cat4k, cat6k, ISR and ASR1k.
