Cisco launched their new application acceleration appliance, the ACE (Application Control Engine) 4710. At just under $16,000, this device is aimed at small and medium enterprises. It can support up to 50 virtual devices at throughput of 2 Gbps, enabling organizations to get the performance and efficiency they need to host and access web-based applications for their users. In addition, Cisco also rolled out their WAAS (Wide Area Application Services) Mobile Software product which accelerates TCP-based applications used by mobile and remote users. Check out this Computerworld article for more details about these new Cisco products and what it means to the networking market as a whole.

One of the ways to organize your network so that it is easier to manage and protect is to segment it into smaller, interconnected subnets. Using a virtual LAN, or VLAN, you can easily and conveniently set up separate subnets, and connect ports from various switches, or even separate buildings, so that they are a part of the same broadcast domain. You can learn more about the virtues of VLAN’s, as well as how to go about configuring them, by watching the Configuring VLAN’s screencast by David Davis on SearchNetworking.com

If you have to connect multiple sites that are not physically in the same building or campus, it can be a little tricky establishing the kind of connectivity and throughput you need for remote sites to work effectively with the primary servers across the WAN connection. Dividing the file size by the projected network bandwidth can give you a theoretical data transfer speed, but factors such as packet loss or the protocol used can add significantly to that time. Take a look at networking expert David Hughes answer to How do I calculate the time taken for a file to be transferred over a WAN link? to learn more about the factors that may impact your rate of data transfer and some tips to help you optimize your WAN connection.
