Cisco Live Cancun Delivers Great Conversations on Service Provider Innovations

Guest Blog by Igor Dayen, SP Product and Solutions Marketing

Cancun is a paradise for many and thus it is known to draw crowds. Another reason for Cancun’s popularity is the addition of the Cisco Live Conference right in the center of this resort town. This event allows Cisco customers, executives, experts, and partners to share insights on new Service Provider technologies and their potential to transform the way we work, learn, and play. This year we had a successful conference showcasing service provider product and solution demonstrations as well as technical training. The demonstrations in the service provider booth and the breakout sessions that were presented to the attendees were very well aligned.


Cisco Live is Cisco’s premier education and training destination for IT professionals worldwide. With that spirit, Cisco Live Cancun proves to be Read More »

The Internet of Everything and Big Data Analytics Can Re-Shape our Digital Lives

The release of the fifth annual Cisco Global Cloud Index highlights the potential impact that Internet of Everything (IoE) applications could have on data centers and cloud computing infrastructures. The growing digitization trend is creating massive volumes of new digital data that represent both challenges and opportunities. As a proof point, by 2019, data generated by IoE apps is expected to reach 507 ZB annually — 49 times higher than total annual data center traffic of 10.4 ZB for the same year. Here are a few brief visual insights into the possible impact of IoE and Big Data on our future digital lifestyles.

  1. Data is everywhere and growing!

By 2019, there will be 24.4B IP connected global devices and connections, an average of 3.2 devices and connections per capita. Per the GCI Forecast, the total amount of data generated by people, machines and “things” will be a “staggering” 43 Zettabytes per month.


  1. Some of this data is finding a home on data centers. The (GCI) forecast estimates that the total volume of stored data on devices and in data centers will reach 3.5 zettabytes by 2019. Global data center computation and storage capacity is also on the increase— 2.5 fold workload growth between 2014 and 2019.

Storing this data is one thing, but its true value lies in Read More »

Simple Device Management, Network Provisioning and Network Assurance for Small Carriers & RLECs

Guest Blog by Alison O’Brien, Product & Solutions Marketing Manager

Small Carriers and the NMS/EMS

Small carriers and rural local exchange carriers (RLECs) often forgo Network Management Systems/Element Management Systems (NMS/EMS) platforms because they don’t have dedicated IT departments. They often have limited staff, time and in some cases lack the breadth of technical IT skills needed to manage complex NMS/EMS platforms. In addition, finding a NMS/EMS solution that is priced to match their network size and that is easy to use and deploy can be a time consuming (if not impossible) task.

The Value of Network Management

Even though they may not use a NMS/EMS platform, these service providers do recognize the value of using a management tool. They know how an NMS/EMS can efficiently perform device management, network provisioning and network assurance tasks. They also know that an NMS/EMS can provide insight into network operation and performance, enabling their staff to more accurately respond to potential problems as well as automate manual tasks. And finally, they know the added value that an NMS/EMS can provide as they grow their business – particularly how it can support the expansion of new services.

3 Key Success Factors for Multi-sourcing

The rise of multi-sourced IT delivery models is well documented, and multi-sourcing is now accepted as the new normal. Today’s outsourcing market demands solutions that anticipate and respond to business activity inside and outside the organization while simultaneously dealing with a rapidly shifting landscape of providers. This drives the need for a global digital infrastructure in which information is used to help organizations create real time links between IT organizations seeking to manage support complexity and a growing and ever shifting array of external service partners that includes traditional outsourcers, managed service providers, telecom operators, and cloud service providers. Enabling this shift are three key success factors:

  1. The dynamic nature of this ever shifting landscape becomes a defining point in new strategies and new tools are needed to address that new reality.
  2. Decisions being made 24/7 are profoundly impacted by an organization’s capacity to have every available piece of information, from all sources, accessible immediately.
  3. The ability to deliver services of all kinds faster, more reliably and more affordability is of prime importance in today’s market.

Sourcing is becoming a critical success factor for IT management;  in fact many now consider the CIO the “Chief Integration Officer”. The multi-sourcing challenges that IT and business managers are facing today have never been so complex. In addition to cost considerations there’s a simultaneous laser focus on security, agility, alignment between sourcing and business strategy are more and more in focus.

Conquering Complexity in a Multi-Sourced Ecosystem

Multi-sourcing is not as straightforward as it might appear. There are challenges even for organizations that have spent time developing their future operating model and included a Service Integration and Management (SIAM) function. The  factors in the figure below underpin successful multi-sourcing with SIAM:

Key Success Factors for Multi-sourcing

Figure includes success factors for effectively operating in a multi-sourced environment.

 Critical Components

  • Effective client organization:
    In any sourcing arrangement, the client IT department is accountable for the IT services delivered to their business. When multi-sourcing, the client has multiple direct contracts with many suppliers, so a strong commercial management function is also required.

Server Load balancing with NAT, using Nexus switches: ITD

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 :

  1. Zero latency load-balancing.
  2. CAPEX savings : No service module or external L3/L4 load-balancer needed. Every Nexus port can be used as load-balancer.
  3. IP-stickiness
  4. Resilient (like resilient ECMP), Consistent hash
  5. Bi-directional flow-coherency. Traffic from A–>B and B–>A goes to same node.
  6. Monitoring the health of servers/appliances.
  7. Handles unlimited number of flows.
