10 G Network Upgrade

I don't believe I've seen you here before. You may want to subscribe to my feed to keep informed of new posts at DynamicVB.NetRSS feed. Thanks for stopping by!

I received some quotes the other day to bring the majority of our backbone up to 10 Gigs. In order to accomplish this I will need to upgrade to an Enterasys X16 chassis. I originally wanted to leverage my a couple of existing N7 chassis to provide the 10 gig connectivity to the majority of the rest of the network. The plan is to provide a 10 G link to the areas of the campus where the majority of the users are located. Right now we have aggregated gigabyte links to each of the edge switches and that has worked fairly well, but I’m starting to see where these links are being saturated with Video and other multimedia media that is being used in instruction.

We are also in the midst of implementing a new PBX system that while will not be primarily a VoIP solution it does have that capability. While our initial implementation will only have a very small number of IP phones it will have the capability to add quite a few more phones in the future. I need to allow for that now as its seems we may have some funds to replace obsolete equipment and I’ve learned to strike while the iron is hot or those funds may not be available later.

Replacing this equipment will not only allow me to offer increased bandwidth to the majority of my users and we will even be able to allow a good number of users to experience Gigabyte to the desktop, it will also allow me to finally remove the remainder of the legacy switches in the network which will not support QOS and the level of security I like to enforce. This will help me obtain the level of User Personalized networking that I’ve always envisioned. Part of the quote I received includes Enterasys’s new Sentinel Trusted Access Gateway and Trusted Access Manager. This product allows you to bridge the gap between your intrusion detection system and Access Control lists which allows you to dynamically react to threats on your network. This is very important in a school environment where students are constantly connecting infected laptops to the network. I’ve implemented ACL’s where these accounts only have access to certain areas of the network, but I still have to allow them access to the student servers, so having a more complete solution like this will allow me to still offer these vital services while at the same time protecting us from the threats these uncontrolled computers may introduce into our network.
