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 »

2012: The Year of the Gateway

By Ken Morse, CTO, Cisco Service Provider Video Technology Group

And here we are, video-side friends, at the start of yet another year. As we move together into 2012, I hereby declare this to be the year of the gateway.

The natural sidekick to the gateway, of course, is the client — and by “client,” I mean virtual or “soft” set-tops. CPE, and CPE software. The suite of stuff that’s going to connect up all the tablets, laptops, and new video screens we keep purchasing, as consumers, to the screens we’re used to watching (meaning TVs) for premium, subscription video content.

Let’s look more closely at the gateway, since I just so boldly declared 2012 to be its breakthrough year. And in particular, allow me to hone in on the Multiscreen Video Gateway line we’ve been working on and trialing with customers over the last year. A quick look under the hood of the Cisco 9800 series gateway, Read More »

Leading the Charge in the DOCSIS Revolution

It was only a matter of time before DOCSIS 3.0 swept the cable industry. The benefits that DOCSIS 3.0 IP capabilities can deliver—more content, more mobility, more personalization, all at a lower cost—are simply too great to ignore. That industry evolution is now picking up speed, and I’m happy to report that Cisco is leading the pack in DOCSIS 3.0 technologies.

LightReading recently published quarterly market share estimates for August 2011. The upshot: Cisco is maintaining “a hammerlock” on the CMTS market, with a global market share of about 60 percent.

ACG Research (ACG Market Release 2Q11 Worldwide Video Infrastructure) found similar results, stating that Cisco’s CMTS market share grew by nearly 3 points last quarter to a commanding 65.8 percent of the market. Read More »

Reliability Doesn’t Come Easy

Public Service Announcement: Call Before You Dig (or “10 Most Bizarre and Annoying Causes of Fiber Cuts”)

At Cisco, we strive to provide the utmost in reliability and are particularly pleased with the market leading reliability we have with our IOS XR operating system on our ASR 9000 system and CRS routers.  Whether it’s video, mobility, broadband or voice, reliability is key for a good experience.  However, while we, at Cisco enable the experience, providers are the ones who deliver it – and in doing so, there are huge number of network heroes and heroines to make it happen. When it comes to fiber optic cable, someone somewhere actually has to go out and dig the trenches or hang the fibers, regardless of weather, critters, or angry land owners. This week on Lightreading.com, we saw an article worth sharing from our friends over at Level 3 Communications, “The 10 Most Bizarre and Annoying Causes of Fiber Cuts.Read More »
