Abstract

The invention discloses a collaborative network measurement method and system oriented to a hybrid programmable network environment. The invention includes judging whether a target flow is a potential large flow according to a count value sent by a programmable network device or a copy of a message sent by a non-programmable network device. Obtain the possible path of the target flow and pull the count value of the target flow from the programmable network device; for each possible path of the target flow, the count value pulled by the programmable network device and the target flow sent by the non-programmable network device The maximum value of the count values ​​of the packet copies of the target flow is used as the count value; the total count value is obtained by summing the count values ​​of all paths of the target flow, and if the total count value exceeds the global large flow threshold, the global large flow is reported. The invention can realize high-efficiency detection of large flows in a hybrid programmable network, and achieves less resource occupation and fast operation speed, and can adopt a parameterized limiting method to meet different resource and performance requirements of different network managers.

Description

technical field [0001] The invention relates to a network flow measurement technology, in particular to a collaborative network measurement method and system for a hybrid programmable network environment. Background technique [0002] When the total number of bytes or packets of a certain flow exceeds a certain threshold, it is considered a large flow. Timely and accurate detection of large flows is a prerequisite for effective network tasks such as traffic engineering, routing planning, and anomaly detection. With the continuous introduction of new programmable network devices, researchers have designed different flood detection algorithms based on this new device. However, in an actual network environment, due to various reasons, it is usually not possible to replace all network devices with programmable devices at one time, and a more general upgrade method is incremental upgrade. This upgrade method results in a mixed programmable network environment consisting of prog...
