Since the early 1990s, we’ve watched as the number of entries on the Internet routing table has steadily grown. In 2008 the table reached 256,000 routes, triggering action by network administrators to ensure the continued growth of the Internet. Today we know that another significant milestone has been reached, as we officially passed the 512,000 or 512k route mark!
Our industry has known this milestone was approaching for some time. In fact it was as recently as May 2014 that we provided our customers with a reminder of the milestone, the implications for some Cisco products, and advice on appropriate workarounds.
If you would like to revisit that information, you can find the customer support article here: The Size of the Internet Global Routing Table and Its Potential Side Effects (12 May 2014)

Customers demand their Internet to always be on, and service providers -- especially those serving businesses -- strive to meet this with “five nines” of availability. That is to say they aim for a service level that only allows for about 5 minutes per year of downtime. Achieving such performance is no simple task, but is a key differentiator for 123Net, a Michigan based company offering premium voice, data, and colocation infrastructure services.
As 123Net has built out a 2400+ mile fiber network powered by Cisco optical technology. Most Read More »

In the second part of my blog series I want to cover one of the main concerns that Services Providers are facing as they explore moving to NFV and that is performance and scalability. Common concerns I hear center around latency, throughput, queuing capabilities and security. These are valid concerns since SP’s have service level agreement (SLA’s) with the their customers which lead to penalties if performance drops below the SLA. So will a virtualized network function perform at the same level as a purpose built networking device? Read More »

As any geek, I find it a lot of fun to get some hands with the new technology -- be it a new gadget, new product or a solution.
It’s not very often that I have a chance to play with a whole new protocol. EANTC (European Advanced Network Testing Center) interoperability testing gave me such a chance. The bulk of the work happened on EANTC premises in Germany this past February. The overall activity involved many representatives from various vendors making their devices talk to each other. The goal is to test the protocols in several areas, including MPLS, SDN, and IPv6, but the highlight for me was the testing of MAP (Mapping Address and Port) -- a new protocol to enable the sharing of IPv4 addresses by several customer premise devices without keeping the state at the service provider end.
This protocol is being developed by IETF, and has two flavours, the standards-track “MAP” which uses encapsulation to transmit the packets, otherwise known also as MAP, and the experimental track “MAP-T” -- which uses the address family translation in order to send packets, instead of the encapsulation.

The Global Certification Team is proud to announce that the Cisco Aggregate Services Routers (ASR) 9000 series have completed USGv6 Certification on software version 4.2.1 or later, with USGv6 SMU. The details of the certification can be found at https://www.iol.unh.edu/services/testing/ipv6/usgv6tested.php?company=7&type=Router.
The Cisco ASR 9000 system incorporates innovative technologies such as Cisco Network Virtualization (nV) technology, which intelligently blends the edge, aggregation, and access points to simplify operation and accelerate IPv6 services. Two new nV enabled platforms provide additional flexibility and support to optimize service delivery. More information can be found at Cisco.com
