I’m a Believer; the World is Running out of IPv4 Addresses!

By Gina Nienaber, Marketing Manager, Service Provider (SP) Marketing Routing and Switching

Once again, just in case you missed it, the world is really running out of IPv4 Addresses. This time it is for real and if you are not a believer yet, you can investigate and find the second of the worlds five Regional Internet Registries (RIRs) is about to run out of IPv4 addresses. News of this historic event broke last week through an Internet Society guest blog post by Axel Pawlik, Managing Director of RIPE. The blog announced we clearly have turned another page in the IPv4 history books as the Réseaux IP Européens Network Coordination Centre (RIPE NCC) has begun allocating their last IPv4 /8 blocks.  If you are not familiar with RIPE NCC they are the independent, not-for-profit membership organization that supports the infrastructure of the Internet in Europe. The most prominent activity of the RIPE NCC is to act as the Regional Internet Registry (RIR) providing global Internet resources and related services (IPv4, IPv6 and AS Number resources) to members in the RIPE NCC service region.

What does this really mean?  How many addresses are left to allocate? If you’re Read More »

Appealing to the Omnichannel Generation – Catching mobile shoppers anytime, anywhere

Today’s consumers are technology enabled, capable of shopping any time, any location and geographically mobile.  Catching and keeping these shoppers are not easy tasks for brick and mortar or e-Commerce retailers today.

What are some innovative ways the retail industry is adjusting to the needs of shoppers today?

Online Commerce with Pop-Up Stores and Personalized Products

 

This was the scene in San Francisco this week where IndoChino, a menswear provider and tailor company, set up a one week temporary location on the busy Market Street.  Integrating made to measure tailoring, traveling locations and online storefront, this allows customers to get measured for custom suits on site and products delivered to home.

Future orders for personalized products can be placed online including shirts and accessories.  The result combines the scaling of mass production with personalized products, online customer service and only one on site visit in pop up store locations.

The Age of Hypervisors

The science behind Virtual Machine Monitors, or VMM, aka Hypervisors, was demystified almost half a century ago, in a famous ACM publication, “Formal Requirements for Virtualizable Third Generation Architectures”.

In my life, I had the honor of working on some of the most bleeding edge virtualization technologies of their day.  My first was IBM’s VM, VSAM and a host of other v-words.  My last was at XenSource (now Citrix) and Cisco, on what I still think is the most complete hypervisor of our age, true to its theoretical foundation in the Math paper I just mentioned.

Though Xen is arguably the most widely used hypervisor in the Cloud or sum of all servers in the world today, I actually think its most interesting accomplishment lies in what its founders just announced this week.  Therefore, I want to extend my congratulations to my good friends Simon Crosby and Ian Pratt for the admirable work at Bromium with vSentry.

I think it is remarkable for two reasons.  It addresses the missing part of what hypervisors are useful, which is security; for those of you that actually read Popek & Goldberg’s paper, you would note that VMM’s are very good at intercepting not just privileged but also sensitive instructions, and very few people out there, until now have focused on the latter, the security piece.  But there is one more reason, in fact the key point of this paper, the necessary and sufficient conditions for a system to be able to have a VMM or hypervisor, and I am hoping the Xen guys who have done so well articulating that for real (not fictional or hyped) hypervisors, can also help sort our the hype from fiction in what is ambiguously called nowadays a “network hypervisor”.

Could this approach be what is actually missing, to sort out truth from hype in what we call SDN today?  Is this the new age of hypervisors?  Or is this just another useful application of an un-hyped hypervisor?

Getting Spicy in Spain, Paella? No, NPS!

Programmability, application aware environments, and software defined networks are popular topics in the industry right now. Network operators see the revenue opportunities to deliver services which can dynamically utilize network infrastructure while meeting application specific requirements. This thought process dominated at this year’s Carrier Ethernet World Congress in Barcelona, and Cisco was helping lead the way.

It was a pleasure to watch some of our thought leaders share their unique and innovative ideas and direction with the larger service provider, vendor and analyst community – starting with Software Defined Networking (SDN).  SDN wasn’t the only topic, we shared ideas around mobile trends such as 4G/LTE and small cells and the resulting network impact, the increasing need to marry the IP layer with the underlying transport layers, and strategies around moving legacy TDM services onto a packet infrastructure.  I love watching the cross-industry creativity flow as we collectively solve today’s challenges posed by the growth of new user trends.

All that said, Read More »
