Abstract: An apparatus and method for detecting a large flow are provided. The method includes: storing flow information corresponding to the received flow in a cache entry; determining whether or not there is a possibility to be determined that the flow corresponding to the flow information stored in an entry to be deleted from a cache by storing the flow information in the cache entry is a large flow; restoring the entry to be deleted in the cache according to a result of the possibility determination; inspecting a packet count of the entry in which the flow information is stored; and determining that the flow corresponding to the flow information stored in the corresponding entry is the large flow, if the result of the packet count inspection is greater than or equal to a preset threshold value.

Abstract: According to an aspect of the present disclosure, there is provided a method for estimating a total link service rate using packet metadata, the method comprising: extracting a packet satisfying a predetermined condition from each flow; extracting a link service rate from metadata of the extracted packet; and estimating a total link service rate based on the extracted link service rate, wherein the packet satisfying the predetermined condition is determined based on an estimation reference time and finish times of consecutive packets, and wherein the finish times indicates ideal transmission finish times of the packets.

Abstract: Disclosed are an apparatus and method for estimating network maximum delay. The method of estimating network maximum delay may include: estimating first maximum delay using a first parameter caused from a flow and a second parameter caused from a network; estimating second maximum delay using a probability distribution based on packet delay information about the flow admitted to the network; and estimating a mixed maximum delay by mixing the first maximum delay and the second maximum delay.
