Abstract: A system and method according to the invention provide an efficient resource allocation when receiving connection requests from different servers for data transfer and the efficient resource allocation is achieved by identifying and assigning a quality factor to each originating server. When an originating server presents an abusive behavior, it may be assigned to a state that has a low quality factor, thus receiving little resource from the system.

Abstract: A compressed pattern matching based on LZW compressed sequences with a simple bitmap-based realization of the Amir-Benson-Farach algorithm is provided. A suffix trie for a searched pattern is determined and a LZW trie is constructed for a compressed data. For each data chunk in the compressed data a variety of information is determined and a node is added to the LZW trie. The queries used to determine the information are implemented through bitmaps, and allowing identification of all occurrence of the searched pattern.

Abstract: A system and method for forwarding data packets with quality of service and rate control. A plurality of data packets are received from a plurality of sources. The header information of each data packet is extracted and compared against a plurality of tables, and then new header information is assembled based upon the comparison results. The data packets have their headers replaced by the new header information on the fly before being sent to their destinations, or the new header information may be dropped if certain conditions are met.

Abstract: The present invention is to disclose a scheduler which comprising a priority tagging module for receiving a plurality of information chucks, a plurality of output lines, and a WRR (weighted round robin) module. In this regards, each information chucks are tagged with a priority tag by said priority tagging module according to a priority classification scheme. In addition, the WRR module further comprises a bucket list, which has a plurality of buckets, and a control module. Each bucket stores a ticket, which comprises an identification representing one of the plurality of output lines and an associated weight value of the represented output line. Besides, the control module receives the tagged information chucks from the priority tagging module and schedules the tagged information chucks into the plurality of output lines according to a scheduling scheme based on said bucket list.
