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.
Load-balance traffic to 256 servers of 10Gbps each.
Load-balance to cluster of Firewalls. ITD is much superior than PBR.
Scale up NG IPS by load-balancing to standalone devices.
Scale the WAAS solution.
Scale the VDS-TC (video-caching) solution.
Replace ECMP/Port-channel to avoid re-hashing. ITD is resilient.
Mobile is a fast-changing industry! Every year there are new devices, new technologies, and trends.
China is one of the fastest growing mobile markets in the world with:
1.2 billion mobile connections and growing.
The number of 3G mobile telephone users reached 386 million in November 2013, a growth of 154 million over the same period of last year.
Smart phones in China reached 348 million units from January to October 2013
December 2013, China had 500 million mobile Internet users, a growth of 80.09 million compared with that at the end of 2012
The number one mobile operator in China is China Mobile with an estimated 781M subscribers as of Q1 2014. To handle such a large customer base China Mobile has become an industry leader with their vision of Network Functions Virtualization (NFV) in the quest to control operational costs and create the network elasticity new services creation.
Just as Cisco did in the China Mobile Booth at MWC 2014, Cisco is joining China Mobile at Mobile Asia Expo (MAE) in their “Network Function Virtualization Demonstration” located in the China Mobile

So last week I attended the mobile industry’s World Cup or Super Bowl, the 2014 Mobile World Congress in Barcelona, Spain. The GSMA has just reported that more than 85,000 visitors from 201 countries attended the 2014 MWC attended the 4 day event, setting another new record. Every mobile operator, systems integrator, software and hardware vendor that touched the mobile industry was there. People were everywhere and all I can say was wow….
MWC Hot Topics that companies presented were on monetization, virtualization, and supersizing network components. With all of the hundreds of customers that I had the chance to speak with, virtualization and orchestration were really key areas for them. They came into our booth to speak with us, often confused as to them it seemed every vendor in attendance spoke about virtualization or orchestration, which often led operators to think that any vendor can do it. As many operators that have been evaluating this space for a while have found is that animated slides are easy to do but orchestrating and virtualizing a network is not. If you take a product that was just and “okay product”, then virtualize it, then you have a “virtualized okay product” and sometimes still tied to proprietary hardware.
According to Akshay Sharma, research director at Gartner, the Network Function Virtualization (NFV) market is Read More »
Networking as a technology has been around for decades now and most people consider it to be mature with a crawling pace of innovation. But with big market transitions like cloud computing, nothing can be further from the truth as the Cloud Services Router (CSR) 1000V has proven with its announcement at Cisco Live! – San Diego on June 12th as part of our Cloud Connected Solution launch
