Network wide Bonjour® – How would you support Bonjour across multiple VLANs?

As the saying goes, “every stick has two ends”. While laptops, smartphones and tablets have enabled us to be more mobile without compromising on being “connected,” with it comes challenges such as WIFI accessibility, power consumption and your ability to find network based services, like a printer wherever you happen to be.

To facilitate the ability for an end user to discover Services on a network, various Service Discovery protocols have been introduced. One of the most popular is DNS-SD (DNS-Service Discovery), which in conjunction with mDNS (multicast DNS) make up Apple’s offering called Bonjour. Bonjour enables end users to discover Services on their local network. While Bonjour is focused on smaller networks (e.g. Home Networks) with the advent of mobile customers wanting to discover services in close proximity, Bonjour becomes an ideal option to facilitate that. However, as Bonjour utilizes mDNS which is constrained to a single VLAN, customers are not able to discover services across multiple VLANs.

There are a few approaches being proposed to support Bonjour across multiple VLANs:

The Network on Wheels – Raising Funds for Paralympic Athletes

October 30, 2012 at 9:37 am PST

“You mean you can Facetime us from your camp site”, my daughter said incredulously. “From the middle of nowhere?” she continued.  ”You lot are mad!”  OK she was more annoyed that I was taking our WiFi-only iPad away with me as I took some time out of my day job in Cisco Data Center Services, to participate in 2 stages of the Deloitte Ride Across Britain. Prior to the ride, I blogged about this challenge here, discussing the scale of the event and our target to raise money for Paralympic athletes.   A nine day, 969 mile cycle over some of the most challenging terrain in Britain, the ‘Deloitte Ride Across Britain’ was an immense physical and mental challenge.  From Saturday 8th September until Sunday 16th September (just passed), over 700 riders took part in this epic journey from Land’s End to John O’Groats.  For the second year in a row, Cisco provided key technical support to the riders, so that they were able to focus fully on this enormous and exciting journey.

Harsh Wireless Environment? Not a Problem.

It’s a fact – everyone wants wireless access.  Recent research indicates that by 2015, more US internet users will be accessing the internet over their mobile devices than on traditional computers.   With that many people online and on their mobile devices not having stable, secure wireless access is surely an impediment for companies as well as every day users. Companies leverage mobile devices to enable a more efficient workforce. Mobile devices are used to leverage “always-on” applications, increasing access for employees and as a better means of time management. Both of which increase employee productivity.  Companies also often rely on their wireless network for regulating employee safety.  Such is the case for the iron manufacturing company, North American Hoganas Inc.

With 11 production facilities across four continents in eight countries including the United States, where it staffs 250 employees, North American Hoganas Inc. needed to deploy an end-to-end wireless network in order to keep up with market demands and target new operational efficiencies.  Up to the minute communication is vital not only for business operations, but also for the safety of their plant employees.  Updating employees on risk assessments, proper product handling techniques, and work schedules are just some examples of mission-critical, daily communication from management to employees.  There was one problem that stood between North American Hoganas Inc and a successfully deploying a pervasive wireless network: North American Hoganas Inc. itself.

Status-Quo Disruption: What Constitutes Enough Competition?

By Howard Baldwin, Contributing Columnist

Interesting news came out of Europe last month regarding upstart service providers’ potentially disruptive behavior, as well as the responses of established competitors. The news begs the question about telecommunications competition – when does more competition lead to lower prices, and when does it lead to overlapping investment that drives costs up?

In an area as cutting-edge as telecommunications, does increased competition drive R&D investment or decimate it?
