Making a Case for Programmatic Interfaces in Existing Service Provider Networks – Going Beyond Software Defined Networks

The communications industry has come a long way from fixed, inflexible telephone service optimized for voice to dynamic IP-based connections offering converged voice, data, and video capabilities. Now, both residential and business users are increasingly more mobile and distributed, as are the cloud-based services, applications, and content they want to utilize. Service providers must therefore support a more diverse customer base with more distributed content and applications across multiple geographies, yet still maintain a secure, reliable, and consistent quality of experience regardless of device and physical location.

In the face of greater traffic demands and the risk of becoming lower-margin “commoditized pipes,” network operators must react to three key challenges: Read More »

OK, Now What?

 ”Each success only buys an admission ticket to a more difficult problem.”

-- Henry Kissinger

Following the early successes with network programmability,  the natural question that arises is “where do we go form here?”  Certainly some good things have been accomplished, but in many ways the real work is just beginning. David Ward just posted some musings on where we go next with programmatic interfaces for the network--its a good read and I encourage you to check it out.

IPv6: Enabling the Internet of Things and Smart Grids

The Internet of Things is a fast growing market where IPv6 will play a central role. Cisco has recently delivered a new series of products with very innovate technologies for the energy market with a number of new technologies, all IPv6 based!

Indeed, the new routing protocol for the Internet of Things, RPL, which has been adopted as an international standard by the IETF (RFC 6550) and CoAP, the lightweight resources management protocol specified by the IETF are both IPv6 protocols. With the increasing number of devices connected to IP networks, IPv6 is undoubtedly the protocol of choice for the Internet of things.

A key example of where this comes to play is in Smart Grids.

Cisco Hosts IETF Conference for a Free and Dynamic Internet

Last week the UN’s Broadband Commission held its fifth meeting to discuss how to extend the broadband Internet to the almost six billion people on the planet who have yet to connect at broadband speeds. A critical component to extending the Internet is the work done by the multi-stakeholder technical community, especially the Internet Engineering Task Force (IETF).

From March 25th through the 30th, the IETF held its 83rd meeting and Cisco was honored to be the host sponsor. Over fourteen hundred attendees, from 56 countries, participated in the meeting which gathered a large open multi-stakeholder community of network designers, engineers, operators, vendors, and researchers concerned with the evolution and smooth operation of the Internet. Technologies previously defined by the IETF, such as IPv6 and DNSSEC, are now at the forefront of efforts to ensure the Internet’s continued growth as a trusted platform of communications and innovation for billions of people around the world. As a result, the Internet has now grown to be essential to the 21st century global economy and a key driver of social development due in large part to the work of the IETF.

As the IETF nears its 30th year, challenges still remain Read More »

Getting to the UN Broadband Commission’s 2015 Goals

Earlier this week, I attended the UN’s Broadband Commission meeting in Ohrid, Macedonia, where we discussed initiatives to reach the Commission’s goals by 2015:

1) All countries have national broadband plans;

2) Broadband is affordable in developing countries so that entry-level broadband services cost less than 5% of average month income;

3) Broadband is adopted by 40% of households in developing countries; and that

4) Broadband penetration reaches 60% of the worldwide population and 50% in developing countries

To support this vision of an ever expanding Internet that people see as essential, Cisco sponsored the 83rd Internet Engineering Task Force (IETF) meeting last week in Paris. At the IETF, more than 1,400 of the leading Internet engineers and technologists from around the world gathered to further develop the standards which provide the foundation for Internet services such as domain names, email, the Web, and instant messaging.
