Abstract
A method and system for downloading software managed trees (SMTs) in a network processing system provides dynamic update of frame classifiers while maintaining proper network protocol processing. The network processing system includes a general purpose processor acting as control point processor and a plurality of network processors. The new SMT is built by an application on the control point processor and downloaded to one or more of the network processors. The new SMT is placed in a separate memory location accessible to the network processors, rather then overwriting the existing SMT. The active tree pointers are then changed to transfer control to the new SMT.
