Choose the Best Computer Network Solution For Your Small to Medium Business

Your business is growing. You’ve added 2 new staff members in the past year, and all 5 employees are complaining about the increasing difficulty of sharing files. Your billing database is on a computer which can only be accessed by your administrative assistant, and you are concerned about not having a centralized backup of the files being saved on each employee’s computer. If this all sounds familiar, it may be time to implement a computer network.

In this discussion, we’ll look at two main computer network solutions for small and medium businesses. We’ll explore the pros and cons of each type so that you can decide which network might be the best solution for your business.

Network Basics

Networks begin when two or more computers are connected so that information can be shared. In order to connect to any kind of network, a computer requires a network card and CAT5 or CAT6 cables. (If the computer has a “wireless” network card, radio signals can be used in place of the cables.) A network also requires a piece of equipment called a switch, which acts as a central routing “hub” for the information being shared. A switch is kind of like a mail room in a large company. It makes sure the addressed messages get to the right recipient. Read the rest of this entry »

Improving Video Over Wireless Network Performance

Overview

This article discusses how to improve video over wireless performance. Many companies are using various new video content technologies today such as live video streaming, webcasting, video conferencing and web conferencing. YouTube services continue to be popular and are using increasingly more bandwidth as companies use video for training and marketing purposes. Google language translation service can now convert text, making the English text based videos available to other countries as well. Keep in mind that with the proliferation of company VPNs for security purposes, employees can use wireless at work as seamlessly as at home or on a public network. They can access the same video services from anywhere. This is why wireless is so popular now and the need for video grade wireless infrastructure performance.

The current 80.11a/g wireless access point is easily swamped when several clients start downloading large files and running video applications. The best solution for guaranteeing acceptable video performance is now the 802.11n wireless standard. According to a Cisco forecast study, the number of wireless devices will exceed wired devices on the internet by 2015 and account for 54% of IP traffic. In addition video traffic will account for 90% of the consumer internet traffic by 2015.

Video Basics

Video and voice are real-time traffic streams by nature that are sensitive to network congestion that causes latency (delay). Video has both a data and an audio component. It should be noted that the same performance metrics such as jitter, latency, packet loss and throughput affect video as well as voice traffic across the internet and company network. Packet loss has a greater effect on video while latency affects voice much more. Guaranteeing specific service levels for video on the network could involve implementing QOS, increasing network bandwidth, network design changes and equipment changes. All these improvements are for the purpose of making the network “video ready”. Companies increasingly use web conferencing, webcasts and video conferencing for meetings and for training purposes. Colleges use it to deliver courses as well. It is a very cost effective tool to decrease company travel costs. Read the rest of this entry »
