ITD: Intelligent Traffic Director

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.

Value of Cisco Certifications: Making Money Vs. Study

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 »

Lighting up Cisco’s Packet Optical Network Conference

leonard_lunaBy Leonard Luna, Senior Marketing Manager, Cisco Service Provider Solutions

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.

IWAN Wed: How Glue Networks Improves the IWAN Experience with PfR

Network optimization is a touchy subject for many in the IT world, and a particularly thorny issue for the Wide Area Network (WAN). The idea that the network architecture as designed cannot meet the needs of tomorrow is the cause of much discussion, anxiety and in some cases, gnashing of teeth. However, the reality is that the rate of change of applications and ways the WAN is utilized is accelerating, and the methods of designing, testing, implementing and troubleshooting of today are not keeping pace. In addition, traditional services offered throughout the WAN only offer a partial view of the capabilities of what may be available.

And we continue to evolve the portfolio with the constant software updates.

The new SG500XG-8F8T switch features 8 ports of 10GBase-T copper for cost-effective, high speed connectivity to Servers and Storage devices. Additionally, there are 8 SFP+ slots for 10 Gigabit long-range connectivity over fiber for backbone, stacking, or host connectivity. Up to 8 units can be connected in a single stack and may be paired with SG500X switches in the same stack. It comes with a rich feature set including VRRP Resiliency, IPv6 First Hop Security, Energy Efficient Ethernet (EEE), Auto Smartports, CDP, and numerous Time-based capabilities for enabling items such as POE, ACLs, and 802.1x according to a schedule.

The new POE models expand the 300 and 500 Series portfolio with support for higher density POE capability, together with all models supporting IEEE 802.3az (POE+). The 300 and 500 series switches now incorporates full and half power POE models, thereby giving customers the options to select the models which best meets their needs. The new switches comes with all the rich feature set available with these product families.
