How does Dyband's Intelligent IP Traffic Management differ from traditional bandwidth management?
Traditional bandwidth management employs only basic methods -- static rate limits, simple priorities, or traffic type -- to manage the bandwidth usage of subscribers, as a group, or manage applications. These methods are ineffective for managing Internet access services, since traffic patterns are extremely bursty and vary widely according to individual usage patterns. Rate caps and simple priorities do not eliminate the extreme congestion or packet loss associated with packet floods -- the result of multiple users downloading or uploading at the same time. Dyband automatically responds in real time to changing traffic conditions, anticipating congestion and adjusting rate and priority controls, so that no user is "starved" for bandwidth and all users receive consistent, reliable service.

Isn't bandwidth going to be cheap? Why do I need to manage it?
The demand for bandwidth is growing at an enormous rate. New applications that require huge amounts of bandwidth are being developed and released monthly. As these bandwidth-hungry applications run over access networks, they increase traffic congestion and packet loss problems. Regardless of how much bandwidth ISPs provide on their backbone connections, these problems will exist. Over-provisioning bandwidth to solve the problems of congestion and packet loss wastes money and is not a sustainable business model, especially in today's business environment.

Why is bandwidth management based on traffic type inappropriate for managing Internet access services?
Some bandwidth management products identify, prioritize, hinder and obstruct IP traffic based on traffic type. As a result, some traffic types receive the highest priority and purposely starve lower priority traffic (e.g., video conferencing is given priority over e-mail). Subscribers pay for, and will demand, equal access to bandwidth according to their level of service, regardless of whether they are browsing, watching video, or sending/receiving e-mail. For this reason, prioritizing traffic based on traffic type is not a workable solution for Internet access services.

Can Dyband work in combination with my current network management system?
Dyband provides access to essential operational status information via SNMP, an industry-standard network management protocol. Consequently, Dyband can easily be monitored by existing network management platforms such as OpenView, SunNet Manager, and Unicenter TNG.
