I guess it’s a bit natural to feel a sense of pride when you are a part of the team that has innovated the vast majority of LAN Access switch features in the market. I joined this group about 2 years ago and have been in awe ever since. If innovation and the sheer brilliance of simplicity excites you then this should be a fun read.
It is probably obvious that every single endpoint connects to the network ONLY through an access switch. Even the wireless ones.. through the access point that is plugged into the access switch. So no endpoint can get into the network without going through an access switch.

The deployment of network video applications presents several challenges for the network and application administrator. These challenges can be categorized into having predictability, offering performance, and delivering quality.
The deployment and integration of voice into the network was relatively simple compared to the challenges being brought by multi-faceted IP video applications. As with Voice over IP (VoIP), video over IP allows the reuse and convergence of communications infrastructure. Where different types of delivery mechanisms (satellite, DVDs, taps, and coax) were needed for the various types of video, a single transport system can now be used. With VoIP, there was concern regarding some aspects of network characteristics such as delay and jitter. If the video application is an interactive one like video conferencing, then delay and jitter do remain important. However, in other types of video applications (for example video surveillance), the amount of raw bandwidth to deliver high quality video can also be a limiting factor. Additionally, unlike voice, minute network degradations can result in easily noticeable impairments that remain on screen for a longer amount of time.

The world is becoming flat. Enterprises are optimizing the diverse talents and skills of employees and partners around the globe. The challenge of globalization is to provide effective communication across distances and cultures. Enterprises must focus on improving collaboration. The use of video to communicate and collaborate, for information sharing or e-learning, is perhaps the closest alternative to actually being there, enterprises will be able to transcend physical location. For more information, Cisco conducted an interesting study, “The Psychology of Effective Business Communications in Geographically Dispersed Teams.”
The cost of traveling represents a significant proportion of recurring operational expenses for many enterprises, so many of them are looking for ways to reduce travel costs. The key is to make travel more productive by reallocating travel time to videoconferencing for routine internal meetings, and using that travel budget to visit more customers. In addition to cost savings, enterprises are turning to video to show shareholders and customers that they are serious about reducing their carbon footprint and doing what they can to be a Green company.

Pervasive Video over the network is a topic that we’re hearing a lot about these days, with the recent Cisco launch, as well as stats being thrown around about the number of hexabites that video is consuming according to the Cisco Visual Networking Index (VNI). But where is the proof of this? And how do I deploy and maintain all this video?
Here is one way. In case you missed last week’s Interop IT Conference and Expo in NY, on Oct. 20 and 21st, 2010, the Cisco Medianet team presented a very cool demonstration highlighting current medianet technologies: IP SLA Video Operation, and Auto Smartports were on exhibition. These technologies help organizations deploy rich media services to:
• Accelerate and ease video application deployments
• Assist in validation of rich media service quality
• Diagnose video issues and reduce time to resolution of problems

Enterprises are starting to adopt all types of video usage to significantly increase worker productivity, improve collaboration, reduce costs, move towards Green IT by reducing their carbon footprint, streamline and optimize business operations. Adding new video services radically changes the demands on the network. Video consumes significantly more bandwidth than voice so over-provisioning in the network to avoid resource contention problems is not a viable option. Also, the requirement is not simply about the bandwidth, it is about rich service capabilities that must be enabled in the network; for example, how to protect multimedia sessions in progress against the risk of quality impairment due to intermittent extreme network conditions, and how to efficiently deliver one-to-many interactions. There is a need for the network to be aware and respond to the needs of a range of media and network applications.
