摘要： Provided are a method for Ternary Contents Address Memory (TCAM) table management and a computer-readable recording medium for recording a program that implements the method. The method includes the steps of: a) dividing a memory area of TCAM into fixed-size blocks depending on priority to configure a lookup table; b) assigning a priority to each routing entry being inputted to the lookup table based on prefix length; c) storing the routing entry having been assigned with the priority in a lookup table block of a corresponding priority; and d) when a modification occurs in the lookup table, modifying the lookup table to maintain an arranged state for a longest prefix match.

摘要： A high-speed content inspection apparatus for minimizing system overhead is provided. The high-speed content inspection apparatus extracts content in unit of sub-pattern by inspecting a payload of a packet in units of sub-pattern, and extract target content by inspecting a correlation between the extracted sub-patterns. If a sub-pattern present at the end of a payload is smaller than a predetermined unit of a sub-pattern, position information of the sub-pattern at the end of the payload is rolled back and the correlation is inspected. Accordingly, without having to add another hardware or high-performance hardware, target content can be efficiently detected in real time.
摘要翻译：提供了一种用于最小化系统开销的高速内容检查装置。高速内容检查装置以子图案为单位检查分组的有效载荷，以子图案为单位提取内容，并通过检查提取的子模式之间的相关性来提取目标内容。如果存在于有效负载结束处的子模式小于子模式的预定单元，则在有效负载结束时的子模式的位置信息被回滚并且检查相关性。因此，无需添加另一硬件或高性能硬件，可以实时有效地检测目标内容。

摘要： A packet scheduling method and apparatus which allows multiple flows that require data transmission to the same output port of a network device such as a router to fairly share bandwidth. The packet scheduling method includes calculating an expected time of arrival of a (k+1)-th packet subsequent to a currently input k-th packet of individual flows by use of bandwidth allocated fairly to each of the flows and a length of the k-th packet; in response to the arrival of the (k+1)-th packet, comparing the expected time of arrival of the (k+1)-th packet to an actual time of arrival of the (k+1)-th packet; and scheduling the (k+1)-th packet of each flow according to the comparison result.
