DHCPv6 in the Cloud – DHCP Performance Testing and Results

June 7, 2012 - 1 Comment

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 be configured automatically and maintains a database to prevent two devices from accidentally being configured with the same IP address.  Without DHCP, every device would need to be manually assigned a unique address.  Given the scale of today’s networks, with highly mobile users, converged 3G and 4G networks, and an increasing number of end-user network-capable devices, this would be virtually an impossible task.

This past summer, Light Reading teamed with EANTC, an internationally recognized test center based in Germany, to create an independent public test of a complete cloud infrastructure.  Cisco was the first vendor to accept this challenge.  Part of Cisco’s comprehensive Cloud solution included Cisco Prime Network Registrar.

“In the industry’s first public cloud test, Light Reading and EANTC have found that Cloud infrastructure from Cisco really does deliver.”

After months of independent testing, Light Reading and EANTC have published their findings of the first public cloud test.  The test validated the full suite of Cisco products and solutions supporting the cloud – including Cisco Prime Network Registrar for DHCPv6 services.

Light Reading tested Cisco’s DHCPv6 performance for two primary reasons: the fact that it runs on virtual servers and because of Cisco’s high-performance claims for the solution. Why? As service providers move to cloud-based services, their IP addressing management systems, like Cisco Prime Network Registrar, must operate efficiently in the virtualized environment of the cloud.  And, as IPv4 addresses are being depleted, these systems must also support IPv6.

As verified by Carsten Rossenhövel, Director at EANTC (AG), “Cisco Network Registrar successfully provided IPv6 addresses to up to 18,036 users per second – all from the cloud.” With this level of performance, it is possible for your network to recover from a failure without your customers ever knowing there was an interruption in service.  Secondly, “The setup we used demonstrated that even such basic IT requirements as DHCP can be outsourced to the cloud.” Success!

Cisco Prime Network Registrar offers the industry’s most scalable DHCP server: able to support more than 50 million devices in a single customer deployment.  It also offers best-in-class performance, as demonstrated by the Light Reading/EANTC MegaCloud Test.

See the results for yourself and learn how Cisco Prime Network Registrar can help service providers transition to both IPv6 and cloud-based services.

  1. Great post! In my view, if cloud testing has to survive, it needs to yield high sever compatibility with growing number of devices and unique Ips assigned to them.
