DHCPv6 in the Cloud – DHCP Performance Testing and Results

As service providers move to cloud-based services, their IP addressing management system must operate efficiently in the virtualized environment of the cloud.  And within the cloud environment, these systems for DHCP, DNS and IP address management must also be fast. For example, many organizations have expressed a concern that poor DHCP performance could be the weak link when thousands of customers come back online after a failure event.  If DHCP address requests are handled in a slow or scattered manner, servers will not be able to service all requests in a timely fashion.

Another requirement for IP address management systems is support for IPv6, as the depletion of IPv4 addresses has led to many organizations finding themselves facing a rather accelerated and mandatory migration to IPv6 (read: yesterday’s World IPv6 Launch). While one of IPv6’s promises was the elimination of the need for DHCP, the reality is that centralized network management has made DHCPv6 a necessity.  DHCP allows network devices to Read More »

Leading Belgian Cable Operator VOO Deploys IPv6

Belgian cable operator VOO looked at the future of the Internet several years ago and recognized that they needed a plan to move to IPv6 if they were to continue to efficiently grow their business. As the leading provider of broadband cable services in the southern part of Belgium they provide video, high speed Internet at speeds of up to 100Mbps, and digital telephony services, primarily to residential customers in Wallonia and Brussels. The company has been one of the fastest growing service providers in Europe; since VOO launched its triple play services at end of 2009, they’ve acquired more than 1 million subscribers. VOO also recently acquired a 3G mobile license to expand their service capabilities.

For network operators such as VOO, business and service is continuity critical. They cannot afford to have services affected while they migrate to new technology. VOO ultimately selected Cisco’s Carrier Grade IPv6 solution since we gave them a clear migration path to IPv6 and they sought a trusted partner who could offer a future flexible solution. Using our dual-stack technology with the Cisco CRS-3 and CMTS they can run IPv4 and IPv6 simultaneously in order to maintain a high-quality customer experience during the transition.

Nico Weymaere, VOO’s Chief Technology Officer shares his view on the positive impact of IPv6 for both his company and the Internet:

The IPv6 capabilities of the VOO network will provide them a foundation to easily support new services. As we’ve noted previously with our Visual Networking Index, by 2016, there will be nearly 19 billion global network connections (fixed and mobile); the equivalent of two and a half connections for every person on earth. We can’t get there with the limited address space provided by IPv4.

On behalf of Cisco, let me thank the entire VOO team for putting your trust in us.

The IPv6 Internet for the Next Thousand (Ten Thousand?) Years!

Today marks a huge milestone in the networking industry – the official launch by the Internet Society (ISOC) of the new IPv6-based Internet helps ensure its continued growth and impact on the world economy. This new Internet has been in the works for over two decades, including the publication of the first IPv6 standard (RFC2460) by Steven Deering of Cisco and Robert Hinden of Nokia. Since then the industry has made incredible investments in technology to reach this successful achievement including today’s official participation of over 2000 websites and 50+ network operators. According to some of our own calculations we’re estimating that 30% of the world’s web pages are now directly reachable by IPv6.

For us at Cisco on our Service Provider Marketing team, it’s been an exciting journey. We first sought to make the industry challenge imposed by the exhaustion of IPv4 addresses more widely understood by a non-technical audience. Hence our effort at some humor with Read More »

Announcing Foundation of the Mobile Internet: the Cisco ASR 5500

It’s been a very busy month at Cisco for Mobility:

Less than 3 weeks ago, we debuted the “Your Way” campaign, highlighting the importance of the mobile experience to both our customers and Cisco as a whole.

Just last week, we announced the next iteration of the Cisco Visual Networking Index in which traffic is growing four-fold overall but 18 fold for the mobile internet.  And of the nearly 19 Billion network connections by 2016?  More than half will be on the Mobile Internet.

And today, we announced the newest flagship of our Cisco ASR 5000 series, the Cisco ASR 5500.  The series has already propelled Cisco into a market leadership position in the Mobile Evolved Packet Core space, and the Cisco ASR 5500 will be able to extend the benefits of the series even further for our customers.

ASR 5500 will be able to deliver a 10-times performance improvement in throughput, capable of scaling from hundreds of gigabits to a terabit platform and be able to support more than 60 million concurrent sessions, making the architecture able to support the wide variety of connection centric devices  and applications that we’ve adopted in our daily lives seemingly overnight.  And it’s not just what the Cisco ASR 5500 can support, but also how it supports it.

Using what we refer to as elastic capabilities, ASR 5500 can migrate resources within itself to support say, more signaling in the morning when people are doing a variety of different activities on their commute in, to more throughput when people slow down doing as much activity but begin to, say, watch more video.  Ordinarily, providers would have to build out a great amount of Read More »

The SCTE IP Challenge is back! Are you ready?

By Steve Harris, Senior Director, Advanced Network Technologies

How prepared are you for the future of cable telecommunications? You’ll have a chance to find out with the return of the SCTE IP Challenge over the next few weeks.

With the support of our friends at Cisco Systems, the Society of Cable Telecommunications Engineers has brought back the challenge in a bigger and better way to help test knowledge and heighten understanding of the Internet Protocol (IP) technologies that will shape our industry in the years to come.

To get involved – see below for the cool prizes you can win – there are three things Read More »
