IPv6 at CiscoLive! San Diego

Twice a year, I get to experience a peculiar mix of stress and satisfaction that comes from participating in the design and operations of internal networks for the (US and European) CiscoLive – networks these events depend upon.

My role is vital to the efficiency of the whole system, but certainly not glamorous. If I were to compare the CiscoLive network with a dental office, I’d be the technician that only fixes the upper-right tooth – and ensures you continue to breathe well. More specifically, I’d be working on “the number 6 molar” – because I deal with the client-facing setup of IPv6, and the monitoring of all the related dependencies and results.

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 »
