These services include the tuning and security enhancement of network devices including routers and switches. This offering helps optimize the distribution of available link bandwidth. The different applications and services get the share in the pipe to the desired extent only. The applications automatic adjustments are dynamically made to make the spare bandwidth from idle high priority applications to other routine traffic whenever such a situation arises. The security enhancement service enables the router/switch to provide basic security as a first line of defense, before the specialized security devices can protect the network further. In addition, redundancy is provided in certain networks through rearrangement of topology. These services enhance network performance and security without additional capital investment.
