摘要： An apparatus and method for enabling rapid transfer of safe data in a data communication network. The apparatus includes a plurality of query modules, a search window, a shift detector, and a database of unsafe data. A predetermined portion of the unsafe data's signature is populated into the query modules, and the signature of a received data in the search window is compared against a plurality of query modules. The search window is shifted according to the result of comparison with the plurality of query modules detected by the shift detector.

摘要： 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.

摘要： The present invention discloses a network access admission controller and the method used to determine its schedulability. The basic principle involves determining, for all the connections to be checked, if there is any time slot, among all the time slots within a cycle, that will satisfy the scheduling property without the possible misjudgment of schedulability found in the conventional technology. The inventive method of determining schedulability makes its judgment based on packets issued by all the connections and on each of these connections individually. In particular, a determination is made regarding whether there is a particular time slot, among all the time slots, corresponding to the cycle of connection under evaluation, such that all the time slots prior to it are capable of processing the previously issued packets from the connections having higher priority than this particular time slot. When the connections all have a time slot that satisfies the above conditions, a connection is determined to be schedulable. However, when any of the connections fail to have a time slot that satisfies the above conditions, a connection is determined not to be schedulable.
摘要翻译：本发明公开了一种网络接入准入控制器和用于确定其可调度性的方法。基本原理包括确定所有要检查的连接，如果在一个周期内的所有时隙中有任何时隙，将满足调度属性，而不会在传统技术中发现可调度性的可能误判。确定可调度性的本发明的方法使得其基于由所有连接和每个这些连接分别发出的分组进行判断。具体地，确定在所有时隙中是否存在与被评估的连接周期相对应的特定时隙，使得其之前的所有时隙能够处理来自连接具有比该特定时隙更高的优先级。当连接全都具有满足上述条件的时隙时，确定连接是可调度的。然而，当任何连接没有满足上述条件的时隙时，确定连接不可调度。

摘要： An apparatus and method for identifying undesirable data received from a data communication network. The apparatus includes a data receiver, a database, and a content search unit. The content search unit transitions among a plurality of internal states depending on the received data. A predetermined segment of the received data compared with a state table for a current state of the content search unit. If there is a match, the content search unit moves to a next valid state. If there is no match, the content search unit moves to a failure state. When the content search unit reaches a final state, the undesirable data is identified.
