My previous post examined how a regional Provider Independent (PI) prefix is propagated across the Internet. This post discusses the second aspect of the issue: how does Provider Assigned/Aggregateable (PA) space propagate across the Internet?
In a previous blog series about interfacing with your ISP, I mentioned tools that Internet Service Providers (ISPs) have, such as looking glasses and route servers, that can be used to verify their policies. In this blog post, I want to examine some of those tools, but primarily I want to show how prefixes are […]
We’ve talked about how the Internet is forecast to carry a million minutes of video every second in the next few years, and how Cisco’s Elastic Core solution will help the core infrastructure carry that load. But a scalable and flexible core is only one piece of the puzzle that network operators need. Who else […]
The aim of the World IPv6 Launch was to spark a steady, sustained, growth of IPv6 usage leading up to and continuing after June 6, 2012. The continued growth since June 6 and the milestone reached this weekend is an indicator that this commitment had its intended affect thus far. Cisco now has its own AS (#109) on the network operator list, making it the first in the world that is participating in all three categories of the World IPv6 Launch. User activity as measured by Google hit 0.25% for the first time in March 2011. A year later, on March 10, 2012, it doubled to 0.5% for the first time. It’s taken about 8 months to double that again to reach 1.0% today. If this trend continues, it will double again by mid next year and could break past 10% by the end of 2014. The trend is increasingly clear: If you are a network operator, network-enabled application developer, or anyone else that works with IP and are not running IPv6 now or don’t have a plan in place to make it happen soon, now is the time to get started.
Segment Routing v6 facilitates multi tenancy and traffic engineering in data center networks, leverages IPv6 underlay and forwarding, and is suitable for scalable data center and core/WAN deployments.
As for the last 11 years Cisco sponsored the FOSDEM 2020 conference in Brussels. This is one of the largest, if not the largest, open source conference in the world with this year 872 events spread over 2 days. From a network point of view the important part is that the main SSID at the […]
