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,
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 »
In my job as Program Manager for the Cisco IT Advanced Cisco Experience (ACE) Program, I need to meet regularly with my team members, leaders of the user communities we serve, and other colleagues who are all over the world.
Sure, I could handle some of these interactions with an audio-only phone call, but I’d miss the face-to-face interaction and I don’t have time to travel to meet each team in person. But today I conduct many of these small group meetings and individual conversations as HD-quality video calls over the personal Cisco TelePresence EX90 endpoint that’s on my desk, using the ACE network video services.

Guest Blog by the President and CEO of the American National Standards Institute, S. Joe Bhatia: learn directly from the American National Standards Institute about the importance of standards, how their adoption and promotion can help organizations innovate in a global market, while lowering costs and gaining competitive advantage
Author Bio: S. Joe Bhatia, president and CEO of the American National Standards Institute (ANSI), has more than 30 years of leadership experience in global business operations covering engineering, governmental and congressional liaisons, external affairs, and standardization and conformance, and is a frequent lecturer in the U.S. and around the world on topics such as international trade, technical developments, commercial market access, and health, safety and environmental concerns.
As U.S. business and government leaders seek concrete solutions for job growth and global competitiveness, there is an incredibly powerful tool at hand that is sometimes overlooked. This tool can help U.S. industry tap into new and expanding technologies. It can help businesses out-innovate competitors in the global market. And it can help you cut costs and boost your bottom line.
I’m talking about standardization – and there has never been a more crucial time for American businesses to leverage standards and conformance to gain a powerful advantage.
Standardization not only informs the direction of innovation, it impacts the strength of the American workforce. Standards have the potential to accelerate the idea-to-market cycle, increase the number of U.S. products and services in markets worldwide, and save companies millions of dollars.
In short, standards have the power to turbo-charge innovation and fuel business growth.
But to gain the greatest advantage, you have to get informed, and – better yet – get involved. That’s why the U.S. standardization community has worked together to develop the Standards Boost Business outreach initiative. The goal is to help business leaders understand the strategic and economic value of standards – both to your company, and to our overall national competitiveness. Read More »
