Cisco Intelligent Traffic Director (ITD) is an innovative solution to bridge the performance gap between a multi-terabit switch and gigabit servers and appliances. It is a hardware based multi-terabit layer 4 load-balancing, traffic steering and clustering solution on the Nexus 5k/6k/7k/9k series of switches.
It allows customers to deploy servers and appliances from any vendor with no network or topology changes. With a few simple configuration steps on a Cisco Nexus switch, customers can create an appliance or server cluster and deploy multiple devices to scale service capacity with ease. The servers or appliances do not have to be directly connected to the Cisco Nexus switch.
ITD won the Best of Interop 2015 in Data Center Category.
With our patent pending innovative algorithms, ITD (Intelligent Traffic Director) supports IP-stickiness, resiliency, consistent hash, exclude access-list, 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 much superior than legacy solutions like PBR, WCCP, ECMP, port-channel, layer-4 load-balancer appliances.
ITD provides :
- Hardware based multi-terabit/s L3/L4 load-balancing at wire-speed.
- 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.
- Redirect line-rate traffic to any devices, for example web cache engines, Web Accelerator Engines (WAE), video-caches, etc.
- Capability to create clusters of devices, for example, Firewalls, Intrusion Prevention System (IPS), or Web Application Firewall (WAF), Hadoop cluster
- Resilient (like resilient ECMP), Consistent hash
- VIP based L4 load-balancing
- NAT (available for EFT/PoC). Allows non-DSR deployments.
- Weighted load-balancing
- Load-balances to large number of devices/servers
- ACL along with redirection and load balancing simultaneously.
- Bi-directional flow-coherency. Traffic from A–>B and B–>A goes to same node.
- Order of magnitude OPEX savings : reduction in configuration, and ease of deployment
- Order of magnitude CAPEX savings : Wiring, Power, Rackspace and Cost savings
- The servers/appliances don’t have to be directly connected to Nexus switch
- Monitoring the health of servers/appliances.
- N + M redundancy.
- Automatic failure handling of servers/appliances.
- VRF support, vPC support, VDC support
- Supported on all linecards of Nexus 9k/7k/6k/5k series.
- Supports both IPv4 and IPv6
- Cisco Prime DCNM Support
- exclude access-list
- No certification, integration, or qualification needed between the devices and the Cisco NX-OS switch.
- The feature does not add any load to the supervisor CPU.
- ITD uses orders of magnitude less hardware TCAM resources than WCCP.
- Handles unlimited number of flows.
- Load-balance traffic to 256 servers of 10Gbps each.
- Load-balance to cluster of Firewalls. ITD is much superior than PBR.
- Scale IPS, IDS and WAF by load-balancing to standalone devices.
- Scale the NFV solution by load-balancing to low cost VM/container based NFV.
- Scale the WAAS / WAE solution.
- Scale the VDS-TC (video-caching) solution.
- Scale the Layer-7 load-balancer, by distributing traffic to L7 LBs.
- ECMP/Port-channel cause re-hashing of flows. ITD is resilient, and doesn’t cause re-hashing on node add/delete/failure.

“Why Cisco?” I was asked repeatedly after speaking on a panel about drones. “Why not Cisco?” was my passionate response.
The occasion was the recent NASA UTM Convention at Silicon Valley’s historic Moffett Field to explore creative traffic management solutions for Unmanned Aircraft Systems (UAS), popularly known as drones. At Cisco, we see a full spectrum of public, enterprise and consumer opportunities, as well as an amazing ecosystem of partners evolving around “connected” drones. This isn’t just buzz, but a real business opportunity.
After all, drones capture and transmit “ungodly amounts of data,” as Cisco’s Helder Antunes noted during his keynote session and CNBC interview. Cisco’s network backbone, solutions and applications enable the Internet of Everything (IoE) – the connection of people, processes, data and things – and drones represent important, mobile, data-rich nodes on the network. Please also read Helder’s blog on drones and the IoE here.
When it comes to drones and many other remotely connected and mobile devices, it’s really all about Collaboration, Cloud, Fog Computing – and Analytics, whether at the edge, across the network or in the cloud. To seamlessly transform raw data from sensors and images into actionable insights, an end-to-end platform is needed to optimally capture, store, share and process data most anywhere.
For example, one of the biggest challenges for drone operations today is to efficiently collect and effectively transfer colossal amounts of data over weak or non-existent network links in remote areas. Many times, these processes take days or weeks before the collected data can be processed and meaningful insights can be derived.
High-value crops such as grapes may suffer significant business losses due to such time-lagged decisions. Again, what’s needed is the connection to a reliable, high-speed platform. Cisco’s hardware and software technologies enable virtually real-time decision making without experts having to physically download and tackle the data deluge challenge on-site.
Precision Agriculture, Safety & Security and Field Asset Inspection are some verticals that could immensely benefit by leveraging unmanned aircrafts due to their unique abilities to navigate in complex remote environments.
At the NASA event, Angelo Fienga of Cisco Italy and I demonstrated an interesting use case of how one can utilize Cisco’s collaboration infrastructure to unleash “remote expert” capabilities using drones. We successfully exhibited that by relaying the live camera feed of the drone over to WebEx and TelePresence infrastructure, allowing an agronomist thousands of miles away across the globe to precisely observe, guide and control data collection operation in the field.
So all this and more is why “Cisco and drones” make a lot of sense. I’m excited about the possibilities here, and will share some more ideas during my keynote address at the upcoming InterDrone conference in Las Vegas from Sep 9-11, 2015. I hope to see you there.
Meantime, what applications do you think are better suited for a drone business?

Earlier this summer I was privileged to be the closing keynote speaker at the UTM Convention, sponsored by the Association for Unmanned Vehicle Systems International’s Silicon Valley chapter. The convention took place at the NASA Ames Research Center in California, and focused on the unmanned-vehicle traffic management (UTM) aspect of drones.

You might be thinking, “Cisco is a networking company, why would you be involved in a drone conference?” Well, drones have to be connected, and that’s what Cisco does. They transmit massive amounts of data that must be collected, sorted, and analyzed. This is exactly where Cisco should be playing. Read More »

While digital disruption is overturning incumbents faster than just about any force in history, many business leaders are not getting the memo.
As I wrote in my previous blog, our recent “Digital Vortex” research found that nearly four in 10 top incumbents will be displaced in each industry due to digital disruption over the next five years. Nevertheless, 45 percent of companies don’t consider digital disruption a board-level concern.

Two things happened this year that give me a reason to stay up past 11:30 p.m.: I had a second baby and Cisco started a new partnership with Jimmy Kimmel Live. Usually, I catch clips of late-night shows on YouTube. But when we partnered with the Jimmy Kimmel Live team to reimagine the fan experience, I knew I would have some great TV to watch while up with my newborn.
What they’ve accomplished with the Wall of America, powered by Cisco video conferencing, has been truly amazing. It brings a new and different dynamic to broadcast television. Sure, video conferencing on television isn’t new. The difference is video conferencing at this scale and quality!
The show’s team had a vision to not only create a virtual audience during live broadcasts, but also to have the ability to interact with the virtual audience in meaningful (and often very funny) ways. Whether home viewers connect to participate in a funny game, or talk “in person” with celebrities, the segments never disappoint.
Things I’ve learned since the Wall’s debut: Read More »
