XO Communications announced a suite of network tools for giving its MPLS IP-VPN customers even greater levels of visibility and control over their business applications by using a private web-based interface to select between three service levels.
The XO Applications Performance Management suite provides real-time and historical network, server and applications statistics. 
XO said this enhanced, panoramic visibility enables network managers to quickly identify performance issues, determine if they are application or network specific, and make adjustments to bandwidth and Class of Service settings to optimize maximum network efficiency and bandwidth utilization.
