Cisco Service Discovery Gateway – Enabling Zeroconf in Enterprise Networks
I’ll admit it: I’m what others call an Apple fan boy. One of the many reasons for being one is the polished user experience and the ease-of-use of their products. One of the underlying technologies that enables the user to discover devices and services on the network is Zeroconf or, as Apple calls it, Bonjour.
Zeroconf consists of three major components:
- Address auto configuration,
- Naming –and–
- Service discovery.
If your network doesn’t have a DHCP server or you haven’t statically assigned an IP address to your host, most operating systems will use an automatic private IP address. I’m not going into much detail on address auto configuration except that this is typically done using a technique called APIPA (Automatic Private IP Addressing) for IPv4 the host will use the famous 169.254.0.0/16 addresses or, in case of IPv6, by using link-local addresses only (FE80::/10) which has been designed into IPv6 as a basic functionality from day one. Also, naming is not of much of a concern in the context of this discussion. However, it is worth mentioning that Zeroconf names can contain Unicode characters and whitespace, which can make those names a lot more user friendly and meaningful contrary to pure DNS names.
The more interesting part, as it pertains to Zeroconf, is the service discovery. Read More »

I have been privileged to be part of a very dedicated team of networking subject matter experts for the past 5 years in prepping and running the Ciscolive! event network. Before 2008 the network was installed and monitored by a commercial events networking company. However, it became clear with the number of Technical Marketing Engineers, Services Engineers and product developers on-site for Ciscolive! that we were well equipped to take on the responsibility in addition to our speaking responsibilities.
The preparation for Ciscolive! starts many months before the event with weekly, collaborative Webex sessions to discuss design criteria, venue particulars and product/feature configurations. Generally the teams align into core Route/Switch, Data Center, Security, Wireless, and Network Management/Operations, however we work collaboratively to design and implement the best show network possible. We have individuals that are part of our Cisco Remote Management Services (RMS) team, Video Surveillance and partner support from our CenturyLink Internet Service Provider and NetApp storage vendor.
A small part of the NOC staff will travel to the venue to survey the wireless, power and Internet service capabilities several months beforehand.

Cisco Live! has come to a close and I want my first Cisco Guest Blog post to be about my amazing week in Orlando. I am a Wireless Engineer based in St. Petersburg, Florida and I try to make it to Cisco Live! as often as possible (which has been every other year recently).
The Keynotes were great this year. I loved the Opening presentation by Cisco CEO John Chambers on the Internet of Everything but I think my favorite was the presentation by Dave Evans @DaveTheFuturist on the future of the IoE and how our world will keep connecting. The Closing Keynote with Sir Richard Branson was great. Check out the video of it and the other keynotes on Cisco Live 365! as well.
I also attended a Cisco ISE TECSEC-3671 Tech section on Sunday and it was filled with excellent information. If you are interested in ISE (Cisco Identity Service Engine) take a look at this two hour version of the class. You’ll need to register on the Cisco Live 365!, which is free. at Cisco Live 365! If you don’t know about ISE this PDF gives an excellent overview. In the course of the conference I had the chance to take some amazing sessions and the presenters are always leaders in their field so the Q&A is almost as good as the session.

Last week, I was at Cisco Live in Orlando, Florida where I experienced first-hand the magnitude of opportunity and marketing value that lies in interacting with the customer.
This year’s Cisco Live theme is “What You Make Possible,” and this relates well to today’s B2B marketers and their customers. The message that resonates with customers today is not what “we the company” do, but how we help our customers succeed and thrive long term. As marketers, this means exercising foresight on our customers’ behalf, as well as advocating near-term solutions to help drive their success.
As a marketer, implementing these B2B best practices is the best way to enhance this focus on customers: Read More »

Cisco Live at Orlando in 2013 offers a host of opportunities if you are a service provider or a large enterprise that offers services to internal groups. Watch out for the following five key areas and the respective speaking sessions when it comes to software capabilities of the Routing & Switching platforms—(1) IPv6, (2) SDN, (3) Core IP & Optical, (4) Ethernet Access & Aggregation and (5) IP Routing.
June 2012 officially marked the IPv6 Internet with the World IPv6 Launch led by the Internet Society. Within the first six months, IPv6 traffic broke the 1% threshold and established the fact that IPv6 had moved from an experiment to mainstream phase with US traffic approaching close to 3%. Join us for a discussion on where IPv6 is headed (Session ID: PSOSPG-1330) — new opportunities for IPv6 with Internet of Everything. We will be delighted to share our experiences deploying IPv6 (Session ID: PNLCRS-2303) as our IPv6 gurus highlight deployment best practices and real-world challenges. For those of you in Networking, we got you covered with the Troubleshooting IPv6 session (Session ID: BRKRST-2304).
