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.

Cisco doesn’t usually weigh in on rumor, speculation, or just plain nonsense, but we simply had to address some blatantly misleading information that HP has been sharing with customers and reporters in the wake of Cisco’s industry-changing Catalyst 6500 announcement of earlier this week. I’m a big fan of Dragnet, so in the style of Detective Sergeant Joe Friday, let’s talk about “Just the facts”:
First, Cisco emphatically stands behind the claim of 3x the performance at 1/3 the price when you compare a simple upgrade of Catalyst 6500 versus HP’s A9500. HP is suggesting we should instead be comparing the Catalyst 6500 against their replacement platform, the A10500. We’re perfectly happy to do this but we found it’s really hard to do a comparison with a product that doesn’t yet exist. Don’t believe us? Go look at the HP web site. You won’t find any details to support HP’s claims. Yes, HP did ‘launch’ the A10500 in May, but it still hasn’t been posted to their configuration tool, nor does it appear anywhere on their networking product pages. So is the A10500 real, or is it just marketing until it gets off the factory floor?
Second, HP’s claim that the E-Series has only been around for months is incorrect. The Catalyst 6500 E-Series has been in the market for seven years and is in 80 percent of our installed base customer networks. 80 percent! So, for 80 percent of our customers, migrating to the Sup2T really is as simple as a $38,000 list price upgrade. That’s all it takes to get that 3x performance increase, 4x scalability boost, and access to over 200 new software features. Investment protection has always been a key criterion for Cisco and its customers.
I’ve spent the majority of my time last week mixing it up with the record-breaking crowd of over 15,000 customers, partners, press, analysts, and other Cisco enthusiasts and it was truly gratifying to feel the positivity generated by the basket of Catalyst switching innovations we announced at the show (please take a look at my previous post for details). Here’s a rundown of the highlights:
Catalyst 6500 -- The most widely deployed modular switch gets a big refresh and is poised to take on another decade of challenges
Kumar Srikantan, VP of Marketing for the Scalable Networks Business Unit, discusses the motivation behind the new enhancements made to Cisco’s flagship networking solution, the Catalyst 6500, and its impact to customers. Watch his interview at Cisco Live – The Vibe Extra.

Context-Aware, Cisco Borderless Networks Accelerate the Adoption of Cloud services
According to a recent Cisco Enterprise customer poll, 50% of those surveyed are interested in deploying some type of cloud infrastructure – whether it is public, private, or a hybrid. According to Forrester, (“Sourcing Groups Prepare For 2011 — Cloud Is Key Initiative 11/10”) Cloud adoption is already over 25% in North America, and continues to grow in Europe.
There are many reasons for migration to Cloud, including application portability on any device, business agility to deliver services and expand into new business models, and operational simplicity.
While many headlines talk about the Cloud, there is little mention of the role of the network in enabling Cloud services.
As organizations move to the cloud, and the varied devices and connection types accessing private and public cloud services, they become prone to malware or Web vulnerabilities. There’s also the risk of data loss. Ultimately, IT is faced with “can the network secure these connections, users, and data in a manner that ensures reliability and seamlessness?” It is no wonder that a Forrester blog cited that Security is the #1 barrier for cloud adoption.
Another concern is network performance. 83% of CIOs considered performance a top
concern for cloud services in an IDC Enterprise panel. Management of virtualization has also become more complex. According to an Enterprise Strategy Group study, 44% of IT consider virtualization to have a major impact on network and server management.
In this short interview, Praveen Akkiraju, SVP/GM of Services Routing Technology Group will discuss how Cisco is enabling organizations to accelerate adoption of cloud services by extending Borderless Networks to deliver secure, reliable, and optimized cloud services, “The Critical Role of the Network in Supporting Cloud-Based Solutions”.
