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 »

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 »

100G and Beyond Begins With Cisco Coherent Optical Technology

The Visual Networking Index predicts we’re going to hit nearly a zettabyte of traffic by 2015. Applications such as video and cloud services are consuming bandwidth on the network to the point that 10 Gbps infrastructure is insufficient. Without question, 100 Gbps technology in the data center, network core and edge, and transport is a key enabler to remove bandwidth constraints. Cisco is leading the industry in 100Gbps technology across network architecture, and two major acquisitions recently in the 100 Gbps optical component space drive innovation, reduce costs, and improve performance for our customers.

The first acquisition was CoreOptics, a Digital Signal Processing solution designer which was completed in 2010. CoreOptics provides silicon technology to deliver 100 Gbps coherent optical signals on existing (10 Gbps) fiber infrastructure. This means customers can upgrade to 100 Gbps and beyond without incurring tremendous costs. They can do this regardless if their existing fiber network is Cisco, Alcatel, or Nortel/Ciena. It’s the best 100Gbps DWDM solution in the industry with ultra long haul distances (up to 3000 km, as validated by EANTC) and highest density (3x the competition). Even better, we’ve already shown that it’s capable of taking transmission to 400 Gbps and 1 Tbps super-channels in the future.

The second acquisition, Lightwire, is a silicon photonics company with technology to enable cost-effective, very high-speed optical interconnects using CMOS-based silicon photonic optical transceivers. In non-technical terms, “CMOS” (Complementary Metal-Oxide-Semiconductor) is the industry standard for manufacturing chips without need for exotic materials or processes. This means lower power consumption, higher densities, and lower costs, all of which are critical to reducing the operational cost and carbon footprint of data centers as they scale to 100 Gbps and beyond. With this technology in-house, the advanced silicon optical technology can be utilized across our entire product portfolio.

Our customers are very positive. We’ve announced a number of successful trials in our long-haul DWDM solution, including US Signal, Lumos, and SURFnet. Look for more to be coming soon!

Learn how to Deploy IPv6-Based Cloud Intelligent Networks

The most recent “Megatest” was initiated by Light Reading to assess our CloudVerse architecture. In the second part of the test, Cloud Intelligent Networks, Light Reading sought to validate the performance of Cisco’s IP NGN infrastructure in a world of cloud computing, and so far it’s the industry’s only end-to-end test of public cloud infrastructure.

Key questions which Light Reading sought to answer included:

  • Can Cisco deliver on the scale of network needed to connect customers to the cloud?
  • How can traffic between clouds (data centers) be delivered most efficiently to optimize network resources?
  • How can Data Centers keep up with the amount of traffic between them forecasted in the future, without having to replace long distance fiber infrastructure?

To learn more about how to administer and deploy IPv6-Based Cloud Intelligent Networks, and even have an opportunity to get your own questions answered, please attend a webinar with Sanjeev Mervana, Senior Director with Cisco, Jim Hodges, Senior Analyst with Light Reading, and Carsten Rossenhoevel, the Managing Director of the European Advanced Networking Testing Center.

The webinar will be held on April 4th, 2012 at 11am New York / 4 pm London and you can register at this link here. We look forward to hearing your questions!

First Ever Cloud Infrastructure Test: Cisco Delivers Impressive NGN Innovations

In years past we’ve delivered on what we call “Megatests” – comprehensive evaluations that validate our performance claims. The most recent “Megatest”  was initiated by Light Reading to assess Cisco’s CloudVerse architecture, and represents the industry’s first and only end-to-end test of public cloud infrastructure. The first of four reports focused on the Unified Data Center, including Unified Compute (Cisco UCS), Unified Fabric (Nexus family), and Unified Management.

The second report, Cloud Intelligent Networks sought to validate the performance of Cisco’s IP NGN infrastructure Read More »
