Abstract: A system and method for controlling overall behavior of a network processor device implemented in a network processing environment servicing a communications network. The method includes steps of receiving a guided control frame including one or more control functions for configuring various functional devices within the network processor with device control parameter data; a step of forwarding one or more control functions from a received control frame to a functional device within the network processor to be configured; and, executing the control functions as specified in the control frame. A novel control frame data structure and communications infrastructure is implemented whereby any network processor device operating in a distributed network processing environment may be controlled in accordance with executed control functions and device control parameter data.
Abstract translation: 一种用于控制在为通信网络服务的网络处理环境中实现的网络处理器设备的整体行为的系统和方法。 该方法包括以下步骤：接收包括用于使用设备控制参数数据配置网络处理器内的各种功能设备的一个或多个控制功能的引导控制帧; 将一个或多个控制功能从接收到的控制帧转发到要配置的网络处理器内的功能设备的步骤; 并且执行控制帧中指定的控制功能。 实现新颖的控制帧数据结构和通信基础设施，从而可以根据执行的控制功能和设备控制参数数据来控制在分布式网络处理环境中操作的任何网络处理器设备。

Abstract: PROBLEM TO BE SOLVED: To provide a method and a system for managing a memory in a network processing system for providing the allocation of a physical memory section inside a network processor connected to a control point processor by a bus. SOLUTION: This allocation system provides a memory management layer without the need of a complete operating system interface and supports the asynchronous completion of allocation requests. Multicast allocation is supported and the allocation can be simultaneously requested on the plural network processors. An allocation mechanism returns a token, then a memory position is accessed by a protocol through the bus by using the token, and the allocation performed on the plural network processors where actual physical addresses and memory constitution are different is referred to by a single token.

Abstract: PROBLEM TO BE SOLVED: To provide a method and a system for updating a software managing tree(SMT) so as not to disturb protocol processing. SOLUTION: Concerning the method and the system for downloading the SMT in a network processing system, a frame sorter can be dynamically updated while maintaining suitable network protocol processing. The network processing system is provided with a general processor to be operated as a control point processor and plural network processors. The new SMT is composed of an application on the control point processor and downloaded to one or plural network processors. The new SMT is not overwritten on the existent SMT but located at an individual memory position accessible for the network processor. Next, an active tree pointer is changed to transfer control to the new SMT.
