Cloud is Transforming TV: Cisco Is Transforming Cloud TV Delivery

Screen Shot 2015-09-09 at 11.38.40 AMBy Adam Davies, product marketing manager for Infinite Video, Service Provider Video Software and Solutions, Cisco

By now it’s very clear that TV and entertainment viewing habits are changing. More people are accessing more content on more devices than ever before. Revenue from subscription OTT services is expected to almost double — to $50 billion by 2020 (!) — a shift that represents a huge opportunity for service providers.

To meet this opportunity, service providers – and their partners, like us – need to think differently about how services are delivered. We need to give customers what they want – fast and easy access to the shows they love, when they want them on all the screens they want to use. Plus we need to move fast Read More »

Trust Me: Cisco Hearts Video


I was recently talking to an industry colleague about how incredibly focused we are, as a company, on the video marketplace. I meant it, so I was surprised to see the eyebrow-spiked reaction and their response: “How can you say that, when you just unloaded your CPE including set-top boxes, modems, etc.?”

It kind of floored me, because to me it was obvious. But I realize this is a question many may be asking. My response is this: The decision to sell our set-top, gateway, and overall CPE line to Technicolor wasn’t a separation from video. It was Cisco recognizing that for that part of our business to be at its healthiest and most productive, it was better off in an environment focused on building CPE hardware at scale – which is what Technicolor does.

ITD: Load Balancing, Traffic Steering & Clustering using Nexus 5k/6k/7k/9k

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 :

  1. Hardware based multi-terabit/s L3/L4 load-balancing at wire-speed.
  2. Zero latency load-balancing.
  3. CAPEX savings : No service module or external L3/L4 load-balancer needed. Every Nexus port can be used as load-balancer.
  4. Redirect line-rate traffic to any devices, for example web cache engines, Web Accelerator Engines (WAE), video-caches, etc.
  5. Capability to create clusters of devices, for example, Firewalls, Intrusion Prevention System (IPS), or Web Application Firewall (WAF), Hadoop cluster
  6. IP-stickiness
  7. Resilient (like resilient ECMP), Consistent hash
  8. VIP based L4 load-balancing
  9. NAT (available for EFT/PoC). Allows non-DSR deployments.
  10. Weighted load-balancing
  11. Load-balances to large number of devices/servers
  12. ACL along with redirection and load balancing simultaneously.
  13. Bi-directional flow-coherency. Traffic from A–>B and B–>A goes to same node.
  14. Order of magnitude OPEX savings : reduction in configuration, and ease of deployment
  15. Order of magnitude CAPEX savings : Wiring, Power, Rackspace and Cost savings
  16. The servers/appliances don’t have to be directly connected to Nexus switch
  17. Monitoring the health of servers/appliances.
  18. N + M redundancy.
  19. Automatic failure handling of servers/appliances.
  20. VRF support, vPC support, VDC support
  21. Supported on all linecards of Nexus 9k/7k/6k/5k series.
  22. Supports both IPv4 and IPv6
  23. Cisco Prime DCNM Support
  24. exclude access-list
  25. No certification, integration, or qualification needed between the devices and the Cisco NX-OS switch.
  26. The feature does not add any load to the supervisor CPU.
  27. ITD uses orders of magnitude less hardware TCAM resources than WCCP.
  28. Handles unlimited number of flows.

For example,

  • 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.

ITD Deployment with Transparent mode security devices

ITD (Intelligent Traffic Director) is getting a lot of interest about transparent (Layer 2) mode device support.

Here is a 10 minute video that shows step by step ITD deployment for Transparent mode security devices, such as Firewalls, IPS, IDS, Web application Firewalls (WAF), ASA, Cisco Sourcefire, etc:

ITD is a hardware based multi-Tbps Layer 4 load-balancing, traffic steering and clustering solution on Nexus 5k/6k/7k/9k 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.

On-Demand Video Can Transform the Way our Police Departments Train

While we most often think of the Internet of Everything (IoE) as transforming public safety forces out in the field, change can actually begin before an officer is even leaves the station. Classroom training for officers is crucial, enabling them to stay safe and perform at the highest level out in the field. Current events highlight just how important good training is, ensuring officers know how to act in all situations and act as good example of public safety in their communities. The problem is that police officers work on shift schedules, which makes it extremely difficult to get everyone in the same room at the same time for training.

How do police departments guarantee their officers are trained at the highest level despite this scheduling issue? Video training. Police departments and training officers can use video to produce high-quality educational training tools that can be viewed online at an officer’s convenience. On-demand video recording tools like Cisco’s WebEx are straightforward and easy to use, and allow educational materials to be accessed anywhere via the cloud. These on-demand video presentations help make sure everyone is receiving the same level of training, improving the way public safety agencies operate before anyone even steps foot in the field.

Here are four more benefits that stem from on-demand videos for classroom training:

1. Reduce the need for trainers to be physically present at all classroom trainings

It’s still extremely important for police departments to conduct live training exercises. But by replacing classroom sessions with video training, training officers’ time is freed up to focus more on live training exercises. This makes certain officers are still receiving the training they need while helping departments operate more efficiently.

2. Eliminate the burden of shift scheduling to accommodate training

Juggling day and night shifts with training schedules is a hassle. Agency leaders have to analyze staffing, pull people off regular shifts, fill those spots with other agents and often have to pay overtime to do so. It also involves paying trainers to be onsite for multiple days. Video training allows officers to stay on their regularly-scheduled shifts, preventing the confusion and difficulty of shifting schedules and allowing officers to access training videos at a time that is convenient for them.
