Network customers have always bought networks for one and only one reason: to run their applications over them. Yet for most of that time, those networks have been largely oblivious to the composition of the network traffic they carried. Traditional network tools could tell you whether your network was having a lot of errors, or whether a given link or interface was congested, but they couldn’t tell you what was congesting your network, beyond the limited granularity of a few well-known ports. Finding out that you’ve got a lot of HTTP or HTTPS is not very helpful in finding out whether you’re swamped by personal traffic that needs to be controlled, or by legitimate business traffic that requires an increase in effective bandwidth.
As the U.S. approaches the Thanksgiving holiday weekend, there are likely more than a few IT folks who are saying thanks for the ISR 4000 Series, and the challenges it has addressed. Over the past year, we’ve had over 1,000 customers deploy the ISR 4000 Series, and the industry has repeatedly validated the positive impact of the platform on the IT and networking community:
• “Best of Networking” Award, Best of Interop in Las Vegas (April 2014)
• “Best of Networking” Award, Best of Interop in Tokyo (June 2014)
• And most recently: “Networking Product of the Year” Award, Tech World (November 2014)
Data traffic has grown dramatically in the recent years, leading to increased deployment of network service appliances and servers in enterprise, data center, and cloud environments. To address the corresponding business needs, network switch and router architecture has evolved to support multi-terabit capacity. However, service appliance and server capacity remained limited to a few gigabits, far below switch capacity.
ITD (Intelligent Traffic Director) is a hardware based multi-Tbps Layer 4 load-balancing, traffic steering and clustering solution on Nexus 7xxx series of switches. It supports IP-stickiness, resiliency, NAT (EFT), VIP, health monitoring, sophisticated failure handling policies, N+M redundancy, IPv4, IPv6, VRF, weighted load-balancing, bi-directional flow-coherency, and IPSLA probes including DNS. There is no service module or external appliance needed. ITD provides order of magnitude CAPEX and OPEX savings for the customers. ITD is available on Nexus 7000/7700 series in NX-OS 6.2(8) or later. It is available for demo on Nexus 5k/6k. ITD is much superior than legacy solutions like PBR, WCCP, ECMP, port-channel, layer-4 load-balancer appliances.

Imagine that you see a Tweet today inviting you to apply for a part-time networking job, something you can do in addition to your normal job. You appear to be qualified for the job, and the work looks interesting as well. However, it requires enough of your time so that you would have to set aside your current professional development plans, including study for that next Cisco certification. The job lasts one year.
Would you take the job, setting aside your certification plans for a year? How much money would you need to make in that job before it would entice you to abandon your learning and certification plans for a year?
This post works through a couple of ideas (like the above) about how to quantify the value of a certification. Many people expect that more skills and certifications will give them more Read More »

Timing is everything. Faced with the ever-increasing challenges and opportunities of the Internet of Everything (IoE), the timing of Cisco’s Spring Packet Optical Networking Conference, May 13-15 at the Dolce Hayes Mansion in San Jose, couldn’t be better.
Fondly referred to as the PONC (‘pon-see’), Cisco coordinates this event with its customers and prospects twice a year: a Spring event in North America, and a Fall event in Monza Italy. Besides being an immensely influential source of customer input and feedback for Cisco, the conference’s is designed to foster collaboration among attendees -- often highlighted by compelling customer presentation and/or panels discussions by luminaries from the world’s leading ISP, OTT and ILEC organizations. This year will be no different, and we look forward to you helping us Light up our Spring event.
Bill Gartner, Vice President and General Manager, Cisco High End Routing and Optical Business Unit, provides a PONC overview and invites you to participate.
