A system using a "provisioning engine" that performs high-speed identification, analysis and processing of information in a network. The provisioning engine applies rules to allocate network resources, such as bandwidth, to achieve specified performance. The provisioning engine can transfer, monitor and control information flowing through it, such as data packets. It is provided with an extremely fast mechanism for handling routing and data flow manipulation of the packets. This allows fast, "wire speed," processing of units of information, such as packets, to specific, guaranteed flows and virtual circuits in real time. A preferred embodiment discloses dedicated architecture to process the data traffic. The dedicated architecture uses portions of packet header information to identify traffic types. The types are mapped to a service class that can already exist or that can be created to meet a traffic type bandwidth requirement. Predefined rules based on customer needs, service provider guidelines, bandwidth availability, etc., are then applied. This allows use of Layer 1 through Layer 7 data fields to be the basis for provisioning, security, monitoring and control of packet flow at full line rates.
