The Foundation for a Business Relevant Network

With the growing influx of new mobile devices, connected things, bandwidth intensive applications and more data, the network is more relevant to business success than ever before.  Back in June of 2012, Cisco saw that we needed to move away from multiple network systems loosely linked together to an agile and simple infrastructure, streamlined policy and centralized management would be needed to support new business demands. We called it Cisco Unified Access and we aligned the solution to three pillars: One Network, One Policy and One Management.

For the last few years, we have focused on delivering new products and functionality under this Unified Access model. Below is a timeline of products released as part of the Unified Access framework. Cisco lead the way in delivering gigabit 802.11ac Wi-Fi., converged wireless control in access switches and through the acquisition of Meraki – a complete cloud-managed network solution.

The timeline above doesn’t represent every feature and function we have delivered, but it shows Cisco’s commitment to this Unified Access model, both from a cloud-managed and on-premise solution perspective.

Today, Cisco is announcing a number of new products and new functionality to existing products that will help mobilize the workforce, secure the business and increase IT agility. The announcement includes the following: Read More »

Cloudburst: iOS 8 Generates 50% Increase in Network Traffic

Many network engineers recall the iOS7 update on September 18, 2013 as one of the most historic download days of their network’s history. All the more reason for us in the wireless world who anxiously anticipated the September 17 release of iOS8.

We asked a few of our customers to monitor the effect of the software release on their networks and the results for the first two days are in. Those in the education and healthcare space in particular are filled with early adopters of WiFi technology and devices, and eager to get their hands on the latest updates.

Joe Rogers, Associate Network Director at the University of South Florida shared this picture with us from 1pm September 17th, showing 1 Gbps more traffic than he would normally see at this time of day:

Another customer, Greg Sawyer, Manager of Infrastructure Services, shared this picture of the iOS8 effect on his network at the UNSW Australia.

He noted that his experience handling the release this year felt smoother than last year, despite the new peak internet download of 4.65 Gbps and 21Tb downloaded for the day! Not too surprising when considering that there were 27,000 concurrent connections on the wireless network and approximately 60% of those being Apple devices.

How should organizations be considering and handling these network spikes? I sat down with Cisco technical leaders Matt MacPherson and Chris Spain (@Spain_Chris) to get some insight on the effect of big updates like iOS8 on the wireless network. Here are some of the highlights of what we discussed:

The World We Live In

The truth is, more and more services are being moved to the cloud—a cloud that will push updates to millions & in the future billions of users and devices on our networks. Read More »

Working Remotely Just got Better With OfficeExtend 600 Series AP’s

It’s always been important to remote workers to have a solution that provides both secure connectivity to their corporate network and simple user experience.With the recent Summer Blockbuster release of the Cisco Wireless Release 8.0, using the OfficeExtend 600 Series Access Points (OEAP-600) just got better.  Here are a few of the enhancements that come to OEAP-600 with Release 8.0:

  • Firewall for personal networking – Provides port/application protection for personal network traffic that can be controlled by the end user. While the corporate firewall is protecting your corporate data traffic, you now have the capability to make your personal network traffic more secure also with this feature.
  • Split-tunnel for Internet traffic – Enables corporate clients to reach the Internet directly through the WAN instead of tunneling the data traffic through the corporate network. Provides the IT administrator the flexibility to configure the level of split-tunnel capability needed for their network. Together with the existing Split-tunnel for Printer feature the OEAP-600 provides maximum flexibility for printing and managing data traffic between the remote & corporate office.
  • QOS Enhancements for Voice traffic – Assigns high priority for voice packets for remote workers using the OEAP-600 and a VOIP solution in their home or remote office to enhance the remote workers voice call experience. Read More »

Networking: Moving From Open to Closed (Part 2 of 2)

“The past is never dead. It’s not even past.”  — William Faulkner

In the first half of this blog, I explained how MSDCs are like mainframes and super computers. In this half I develop on my thesis that the networks connecting compute and storage resources within the MSDC are becoming proprietary just like they are in mainframes to create a competitive advantage.

Continuing from where I left off, the internal architecture of a mainframe is parallel to MSDC architectures as shown in the figure to the right.

Blog-Pic-4

Mainframe architectures were (and still are) proprietary, in that how the compute and storage resources are connected was an internal engineering design. Each vendor had their own internal design which served as a competitive differentiation. We are seeing the same thing happening in MSDCs. Read More »
