Embodiment Construction

[0082]Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0083] Use the Mininet emulator to establish a network topology and connect it to the controller. This paper samples the mesh network topology to analyze and compare the performance index of the controller. The network topology is composed of 1 controller, 6 switches and 6 hosts, and each switch is connected to each other to form a mesh network of 6 network nodes and 6 host nodes. Such as Figure 5 shown. Then initialize the mesh topology, select switches, measure data, calculate performance and other operations, and analyze the algorithm proposed by the present invention. The flowchart of controller performance analysis algorithm based on adaptive sampling is as follows: Figure 4 As shown, the specific steps are as follows:

[0084] Step 1: Network initialization

[0085] Network initialization, randomly select source nodes and destinatio...

Abstract

The invention discloses a controller performance analysis method based on adaptive sampling, and belongs to the technical field of wireless communication networks. For characteristics of a data streamin an SDN, network overhead factors for measuring controller performances are analyzed, a network overhead mathematical model is built; and existing mainstream SDN controllers (a POX controller, a FloodLight controller, an RYU controller, an ONOS controller and an OpenDayLight controller) are systematically analyzed and compared by means of an adaptive sampling algorithm, and performance indexesof the controllers are quantitatively analyzed, so that a practical and effective research program is provided for future researchers. It shows that the analysis method has the advantages that the SDNcontrollers are systematically and comprehensively analyzed, the relation between the measurement precision and the network overhead is well solved, and therefore SDN controller resources can be fully utilized.

Description

technical field [0001] The invention belongs to the field of future network technology, in particular to a controller performance analysis method based on adaptive sampling. Background technique [0002] With the rapid development of the Internet and the explosive growth of network traffic, the current network applications and scale have increased dramatically, and the network architecture with the TCP / IP protocol as the core has gradually exposed various problems, such as scalability and controllability , security, mobility, service quality, and green energy conservation, etc., especially the protocol-centric network technology evolution route and fully distributed deployment implementation strategy, resulting in a very slow development of network technology, even to some extent caught in a stagnation. Under such a network background, a new network technology architecture is needed to change this situation and accelerate the pace of network innovation. Therefore, future n...
