bandwidth, cable, DSL, overprovisioning your internet, wireless
Hi folks, I wanted to talk about your Internet bandwidth in your client networks! These days most people have either cable or DSL for their Internet access. It’s very rare that you see anyone with just dial-up access. Even wireless Internet services have become popular.
However, the one thing I see over and over again are people oversubscribing their Internet. I think what happens is that non IT people are used to the high speeds that cable and DSL provide at home, and instantly assume that will be good enough for their business. They get all hooked up and then as their business grows and more people join their company, things start to slow down. They don’t realize that the bandwidth on the line is shared amongst all their users.
This problem is now exacerbated because most people have smartphones that also get IP’s from the server via wireless connectivity and they also communicate out through the Internet. I have seen this cause numerous issues with customers and running out of licenses on their firewalls.
People need to analyze their Internet needs and average bandwidth usage and size the Internet pipe appropriately to their business. This doesn’t take much time and their are a lot of freely available tools you can use to help you figure these things out. If you aren’t comfortable doing this on your own, give a quick call to your local IT consulting company and in short order they should be able to help you out.
Don’t yell at your service provider for slow Internet, it might not be their fault.
