Patent number: 7460550Abstract: A storage structure and method having multiple protocol processor units are disclosed. The storage structure comprises a host CPU, a main memory, a storage device, a switch fabric, and a host bus adapter module. The host bus adapter module includes a plurality of protocol processor nodes for processing frames received from a network, and storing those frames into the storage device. A processing module of the host bus adapter module extracts the session information of each frame and compares it with entries recorded in a look-up table. If the connection information hits one entry of the look-up table, the frame can be bypassed into a corresponding protocol processor node according to the definition of the look-up table. Otherwise, a new entry will be inserted into the look-up table for designating a corresponding protocol processor node.Type: GrantFiled: November 3, 2004Date of Patent: December 2, 2008Assignee: Industrial Technology Research InstituteInventors: Jun-Yao Wang, Chung-Ho Chen, Chao-Lin Su, Chao-Hsien Hsu, Cheng-Yeh Yu, I-Cheng Chung
