Smart Business: How To Manage Bandwidth Requirements For Multi-Media Applications

In an enterprise environment, voice and video over IP (VoIP) significantly reduces long distance telephone charges by transferring all long-distance voice data over the Internet connection. It also provides a means for rich multimedia applications converging video, voice and data in a single session. Since VoIP shares the Internet connection with other forms of traffic, it must compete with other applications for network bandwidth. In order to make VoIP a viable business application for this scenario, the quality of VoIP should be equal to the traditional PSTN/ISDN voice and video services.

A typical corporate network environment carries a broad mix of data traffic with different bandwidth needs. Bursty data applications, such as email and the web, have variable and unpredictable bandwidth requirements while streaming real-time applications such as voice and video demand consistent bandwidth allocation and minimal delays. While a 250 millisecond delay in an email or a Web page will probably not be noticed, a similar delay in a VoIP phone conversation or video conference would make conversation uneasy and cause callers to talk over each other.

Streaming applications like VoIP and videoconferencing require performance guarantees to ensure that they do not suffer from bandwidth contention from less critical applications and Internet traffic (e.g., non-critical Web browsing, large FTP file transfers, and P2P uploading/downloading of digital music files). A policy based quality of service (QoS) solution can ensure that your voice and video applications receive the bandwidth they require.

So what's the solution??

First....ensure your network is optimized for sufficent bandwidth....with room for expansion when/if necessary. For businesses with frequent multimedia applications such as videoconferencing....a minimum of DS3 Bandwidth is necessary. Perhaps OC3 for large companies with extensive multimedia load pressures on their network.

Second....allocate your network resources based on business priorities. A commercially available monitoring device will help you monitor and manage network and application performance. This allows you to prioritize traffic traveling over your WAN/Internet connection and guarantee bandwidth for timing-critical, real-time applications like VoIP and videoconferencing. Through such a device specific voice, video and multimedia traffic flows can be identified and the following actions can be assigned: minimum and maximum bandwidth; priorities; guaranteed rate (CBR); fairness; and control over the number of sessions allowed through the network.

Take control of your Internet and WAN resources to optimize the performance of your business-critical applications, VoIP and video traffic. Ensure sufficient bandwidth in your network for near term and expansion needs....and implement a monitoring system to manage the daily operations and priorities.

That's simply smart business.

iPod Download Tips - What You Dont Know About iPod Song Downloads

The technology behind iPod downloads is interesting. If you are an iPod user, it is not new to you that you simply cannot download those stored song files in your iPod to your computer. In short, iTunes only allow a one-way transfer of files, from the computer via iTunes to your iPod device but not vice versa. People have questioned the rational behind this somewhat inconvenient shortfall in the design of these portable digital devices. We will find out in this article how we can work around this inconvenience and also explore other cost-effective ways to download tons of songs and music videos for pennies.

No, it is not because there is a design flaw but rather the design intention to ward off attempts of piracy, ie indiscriminate duplication of music files to be sold or shared. It may sound harsh to say that even sharing song files with friends could be illegal, but it is true that you may be in danger of infringing into copyright laws. The copyright laws are put in place to govern and protect the intellectual properties of their creators, the musicians, etc so that it remains profitable for them to run their music business. Without that, the music industry slowly wanes and dies a natural death. As a consumer, or music lover, you obviously wont want that to happen right?

However, not being able to download iPod songs from iPod to computer meant that we cannot do a backup of our song collection. This can be a nasty experience if our computer crashes or when our iPods are faulty. There is a need for easy transfer of song files between the iPod device and any computer such that retrieval would not be so painful. The piracy-proof?functionality of the iPod device to prevent transfers of songs to a computer ended up becoming a handicap for owners who genuinely just want to do proper backups.

Software developers saw this shortfall coming and have already designed some applications to work around this problem. iPod users can now conveniently carry out transfers from their iPods to their computers with ease, without fear of formatting problems. Heres a list of iPod-compatible software applications supported by Mac/Windows Operating System that are available for downloading. Free trials are available for testing.

1. iPod Music Liberator

2. iPodRip

3. PodUtil

4. iPod Access

With the above software, you can rest at ease, knowing that your private iPod downloads of song and music collection is safe even when your iPod or computer is down. I am sure you have heard of horrific stories where folks who have painstakingly built up a huge iPod music collection only to see them wiped out with a technical glitch. Its not a matter of effort only but the amount of money that has been invested into the iPod downloads.

Fortunately, there is now a better way to download iPod songs, music and music videos. In the past year, other than iTunes, many new players have entered into the market changing the business model of paid iPod downloads. Instead of charging per iPod download of song or music video, these membership sites are offering life-time membership for pennies. Considering the vast library of millions of iPod downloads they offer which range from the latest music to movies and TV shows, it is proving to be a more worthwhile investment for iPod users.
