Server load balancer (SLB) has become very common in network deployments, as the data & video traffic are expanding at rapid rate. There are various modes of SLB deployments today. Application load balancing with network address translation (NAT) has become a necessity for various benefits.
Cisco Intelligent Traffic Director (ITD) is a hardware based multi-terabit layer 4 load-balancing and traffic steering solution on the Nexus 5k/6k/7k/9k series of switches.
With our latest NX-OS Software 7.2(1)D1(1) (also known as Gibraltar MR), ITD supports SLB NAT on Nexus 7k series of switches.
In SLB-NAT deployment, client can send traffic to a virtual IP address, and need not know about the IP of the underlying servers. NAT provides additional security in hiding the real server IP from the outside world. In the case of Virtualized server environments, this NAT capability provides increased flexibility in moving the real servers across the different server pools with out being noticed by the their clients. With respect health monitoring and traffic reassignment, SLB NAT helps applications to work seamlessly without client being aware of any IP change.
ITD won the Best of Interop 2015 in Data Center Category.
ITD provides :
- Zero latency load-balancing.
- CAPEX savings : No service module or external L3/L4 load-balancer needed. Every Nexus port can be used as load-balancer.
- Resilient (like resilient ECMP), Consistent hash
- Bi-directional flow-coherency. Traffic from A–>B and B–>A goes to same node.
- Monitoring the health of servers/appliances.
- Handles unlimited number of flows.

Did you know that October is National Cyber Security Awareness Month? Here at Cisco, we understand how important cybersecurity is in today’s interconnected world. Because the Internet touches an increasingly large part of our lives, it’s necessary to engage and educate the public about how to stay protected. While we highlight the importance of cybersecurity in October, at Cisco we have initiatives and programs in place to make sure the education continues throughout the rest of the year as well.
We start from the inside out, making sure that our own employees are fully educated and trained in the latest in cybersecurity. Our Cisco Security Ninja Program, which challenges participants to reach for higher degrees of competency and proficiency in product security, has been a huge success. Employees can earn four distinct belts– white, green, blue, brown and black – that represent their advancing cybersecurity knowledge. Additionally, we offer a program in conjunction with San Jose State University that enables Cisco employees to earn their Master’s degree in Software Engineering with an emphasis in Cybersecurity. Plus, every year we have an internal conference on security – SecCon – that brings together hundreds of engineers from Cisco offices around the globe to share their knowledge and increase the overall security posture of Cisco products. All of these programs help ensure that our own employees are experts at the latest in cyber protection. Read More »

New, clever, and dangerous malware is being devised all the time. After a piece of malware is well known, signature-based defenses such as antivirus and other detection and prevention tools can catch it. But what about new, increasingly insidious malware that isn’t well known? Last year, Cisco acquired the dynamic malware analysis and threat intelligence capabilities of ThreatGRID. The fruit of this acquisition is Cisco Advanced Malware Protection (AMP) Threat Grid, a technology that complements our AMP products and is currently integrated into Cisco security gear spanning the network, from intrusion detection systems, to email and web security appliances, to endpoints.

As businesses strive to become digital, they need to be more flexible, innovative, and agile than ever. Customers are engaging with businesses differently from how they were just five years ago, and the bulk of their interactions are not with people but with systems (think airport and hotel check-in, ordering a product, or getting a taxi).
For all this to work, it’s critical that the systems on the back end know who you are, where you are, and what you need, to connect flawlessly to the front-end device. That airport check-in app on your phone, for example, requires integration with the airline reservation system, the ticketing system, the baggage handling system and gate information in order to provide full value to you as a user.

The demands of increasingly mobile and digital consumers are creating unprecedented complexity for retailers and brands. How should retailers respond? We’re going to tackle this question together on Twitter next Tuesday, October 27 at 1pm EST/ 10am PST.
Together, we’ll discuss questions such as:
- Who is the new “digital consumer”?
- What does the future of retail look like through the lens of digital technologies?
- What have you learned about the behaviors and expectations of the digital shopper?
- What is the role of security in retail?
- Why “trust” is key in winning wallet share of the digital shopper?
It’s always been my experience that the best ideas emerge from a combination of people with different viewpoints, areas of expertise, and experiences. That’s one reason I’m (@anabellepinto) looking forward to being part of the next #CiscoChat with my colleague, Ron Kjelden (@rkjelden), focused on how retailers can create shopping experiences that meet the demands of the new digital consumer.
