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 »

IBBS Successfully Deploys Cisco Network Registrar, Providing Cloud-based DHCP and DNS Services to over 250 Cable Operators

Integrated Broadband Services (IBBS) is one of the largest cable operators in North and South America? Company name doesn’t ring a bell? You are not alone. According to company executives, “IBBS is the biggest cable company you’ve never heard of.” Here’s why – they’re behind the scenes, working with small and medium-sized local cable operators. IBBS offers hosted or cloud-based services to over 250 cable operators to help them provide data services and voice services to their subscribers – connecting more than one million cable modems across North and South America.

In the late 1990s, small and medium-sized cable television companies across North and South America recognized that to stay competitive with larger players and upstart "triple-threat" providers, they needed to offer high-speed data services to their customers. They faced a significant challenge, however, when it came to provisioning all the new IP-based devices and services they needed to deploy. Writing their own software was a daunting task, but purchasing new solutions was beyond the constrained budgets that most of these companies faced. Read More »

Addressing the Service Provider Transition to IPv6: Carrier-Grade IPv6 Solution (Part 3 of 4)

The transition to IPv6 presents a complex technical challenge, and the business risks for not doing it right are potentially significant, in terms of impact on customer retention and growth, new business models, and competitive edge.

In this third installation of the series, Kelly Ahuja of Cisco and Ray Mota of ACG focus on Service Provider strategies for the transition to IPv6. As Kelly mentions, the Cisco Carrier-Grade IPv6 Solution (CGv6) is designed to help address both technical and business challenges associated with the transition. The Cisco CGv6 portfolio of IPv6 solutions enables service providers to:

  • Preserve investments in IPv4 infrastructure, assets, and delivery models
  • Prepare for the smooth, incremental transition to IPv6 services that are interoperable with IPv4
  • Prosper through accelerated subscriber, device, and service growth that are enabled by the efficiencies that IPv6 can deliver

It’s important to emphasize the word solution. CGv6 solution is not just a line card, or a network appliance, or a software feature. Unlike other companies Cisco has the experience and expertise to help network operators realize the promise of IPv6 by offering full Life Cycle Services Support. This is especially important as not all operators have experience in IPv6 or access to this expertise. Cisco can provide the people, processes and tools to ensure a seamless transition. Some of the capabilities our advanced services team provides include:

Cisco Network Management: Now with New and Improved Management Across the IP NGN

Contributed by David Flesh, Sr Manager, Product Marketing, Cisco Network Management Technology Group

If you’re a network administrator, at times it may seem like the IP network traffic and volume of IP addresses and devices you oversee are increasing at an unmanageable pace.  On top of that, the complexity and size of IP networks continue to expand, and network operators are beginning to transition to IPv6 and introduce new technologies and services into their networks (VoIP, video, cloud computing, virtualization, etc.). Network operators need to accelerate provisioning and simplify service activation.

Given the mission-critical importance of DNS and DHCP services in today’s service provider and enterprise networks, you now face huge challenges with IP address management that must be addressed. Without a fast, reliable, and secure DNS service, subscribers’ broadband Internet access will be compromised. If DNS fails, the Internet will fail. Likewise, DHCP is a core network access technology - every device must be assigned a unique address when connected to the network, a virtually impossible task to undertake manually.

To effectively address these challenges, network administrators need an integrated solution for DNS, DHCP, IPAM (DDI) to effectively manage IP address growth and help automate the adoption of IPv6.

And that’s just what Cisco is now providing.

As part of its service provider network management portfolio, Cisco is introducing Cisco Network Registrar 7.2 which provides an integrated, scalable, reliable solution for DDI across multiple technologies to simplify management of IP addresses and the transition to IPv6. Cisco Network Registrar is the industry’s fastest and most scalable DHCP server - able to assign more than 47,000 leases per second on a Cisco B-Series UCS platform (and 14,000 leases per second on a non-Cisco hardware platform) and support more than 50 million devices in a single customer deployment.
