How Trinity Leeds is changing the future of retail with IoE

Shopping centres have been around for thousands of years, supposedly starting in Ancient Rome. The basic concept of a shopping centre has not changed much since then; a large building, or multiple buildings connected, which contain a variety of retail stores, services and restaurants. However, we at Land Securities, a commercial property group based in the UK, are changing the way customers experience shopping with our newest shopping centre, Trinity Leeds, “the mall of the future.” Read More »

Investigating OpenStacks Multicast capabilities (Part 1 of 3)

This is my first blog post within the Data Center and Cloud technology area. I recently joined the Openstack@Cisco team under Lew Tucker focusing on advanced OpenStack System research as a Cloud Architect. As part of this role I performed a gap analysis on the functionality (or the lack thereof) of multicast within an OpenStack based private Cloud. Coming from Advanced Services I have seen multicast as a critical component of many datacenters providing group based access to data (streaming content, video conferencing, etc.) . Within a Cloud environment this requirement is almost if not more as critical as it is for enterprise data centers.

This blog will be the first in a series highlighting the current state of multicast capabilities within OpenStack. Here, I focused the analysis on OpenStack Icehouse running on top of Redhat 7 with OVS and a VLAN based network environment. I would like to thank the OpenStack Systems Engineering team for their great work on lying the foundation for this effort (preliminary tests on Ubuntu and Havana).

I used a virtual traffic generator called TeraVM to generate multicast based video traffic allowing for Mean Opinion Score calculation. The Mean Opinion Score or MOS is a calculated value showing the quality of video traffic based on latency, jitter, out of order packets and other network statistics. Historically, the MOS value was based on human perception of the quality of voice calls, hence the word opinion. Since then it has developed to an industry standardized way of measuring the quality of video and audio in networks. It is therefore a good way to objectively measure the performance of multicast on an OpenStack based Cloud. The MOS value ranges from 1 (very poor) to 5 (excellent). Anything above ~4.2 is typically acceptable for Service Provider grade video transmission.

I performed the multicast testing on a basic controller/compute node OpenStack environment, with neutron handling network traffic. In this blog, I focus my analysis solely on opensource components of OpenStack with Cisco products (CSR and N1K) being discussed in a follow-up blog. The tenant/provider networks are separated using VLANs. A Nexus 3064-X is used as the top of rack switch providing physical connectivity between the compute nodes. The nodes are based on UCS-C servers.

10 Predictions for the Future of Wi-Fi and Mobility

The close of every year brings startling headlines that herald the continued meteoric rise of mobility. This past year was no exception. The 2014 announcement that there are now more mobile subscribers than inhabitants on the planet exemplified the mobile zeitgeist and its importance in our daily lives.

But, the big mobile news in 2014 was around Wi-Fi. Wi-Fi continues to blanket the world, with iPass estimating that the number of public hotspots will increase almost 8-fold over the next four years to cover 1 out of every 20 people on the planet. And, Wi-Fi is becoming more like the mobile cellular experience. The seamless authentication and experience promised by Hotspot 2.0 is now available, with Time Warner and others announcing last year that they would roll it out across their entire Wi-Fi networks. And, we can now roam to other international Wi-Fi networks, like we do on cellular, with Comcast and Liberty Global, and other providers, announcing global roaming agreements. And, 2014 saw mobile operators beginning to embrace Wi-Fi in a big way. T-Mobile USA began shipping wireless routers to provide five bars coverage at home by allowing customers to make calls over Wi-Fi instead of the mobile network.

Of all the 2014 Wi-Fi activities, perhaps the biggest event was Read More »
