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.

World IPv6 Launch and the Enterprise Network

Today is World IPv6 Launch day. World IPv6 Launch is a follow-on event to last year’s IPv6 day where IPv6 was used for a day. The World IPv6 Launch is the ultimate recognition of the “world” turning on IPv6 and leaving it on: a true milestone for the Internet.

Cisco, along with major Internet Service Providers, home networking equipment manufacturers, and web companies around the world are coming together to permanently enable IPv6. So as we celebrate the permanent launch of IPv6, one may wonder how enterprise networks can benefit from IPv6.  Not only will IPv6 benefit the core of your network but the WLAN as part of the overall network will benefit.

In the past, the perception was that the US Military and China were the ones who were driving IPv6 deployments. That is no longer the case; the fact that there are a limited number of IPv4 addresses doesn’t just affect the just Service Providers but also large enterprise customers. Whether you are a large manufacturer with plants around the world, a university with a growing number of wireless devices or a global financial bank, you all can benefit from IPv6.

IPv6 Security Lab @ Cisco Live 2012 in San Diego

With the proliferation of IPv6, its adoption and deployment, there are new security concerns that apply only to IPv6. Some of these security concerns rely on protocol differences between IPv4 and IPv6 and others exploit the diversification that the two technologies offer. The result could allow malicious users the ability to deploy attacks or evade network threat defense, countermeasures, and controls.

Join us, this Monday (June 11, 2012) afternoon, at Cisco Live, San Diego 4-hour lab session LTRSEC-3033 -- Cyber Aikidō (合気道) Academy: IPv6 Network Threat Defense, Countermeasures, and Controls, to become more knowledgeable about basic inherent IPv6 security features and techniques on Cisco IOS Software and the Cisco ASA 5500 Series Adaptive Security Appliance (ASA). The students will acquire hands-on experience by configuring and testing these security features and techniques in simulated real world scenarios. The threats and protections that are presented apply to Local Area, Enterprise, and Service Provider networks. Students must correctly identify, classify, and deter or prevent the nefarious IPv6-specific behaviors by configuring network threat defense, countermeasures, and controls that will be implemented and deployed on infrastructure devices and validate their effectiveness.

At the conclusion of these labs, students will be more prepared to effectively implement and deploy basic inherent security features and techniques for identifying, classifying, deterring, and detecting attacks, threats, and nefarious behaviors specific to IPv6.

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 »
