Data stream processing method and device, electronic equipment and storage medium

Abstract

The embodiment of the invention provides a data stream processing method and device, electronic equipment and a storage medium. The method comprises the following steps: detecting whether a message flow sent to a central processing unit has a high-rate flow or not; if the large-rate flow exists, calculating the proportion of the message flow corresponding to various message header information in the large-rate flow in the large-rate flow; if the proportion of the message flow corresponding to the first message header information is greater than a first preset threshold, installing a hardware speed limiting entry for the message flow corresponding to the first message header information, and limiting the speed of the message flow. According to the data flow processing method provided by theembodiment of the invention, the generation of the elephant flow in the message flow sent to the CPU is detected, the message header information of the elephant flow is analyzed, the message with more bandwidth occupied by the elephant flow is dynamically suppressed, the elephant flow is prevented from influencing the mouse flow sent to the CPU, and the CPU resources of the switch are reasonablyand fully utilized.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular to a data stream processing method, device, electronic equipment, and storage medium. Background technique [0002] In the network environment, various attack packets are propagated on the network, causing the CPU utilization of the switch to be too high, affecting the operation of the protocol, and even failing to manage the switch. figure 1 It is a schematic diagram of switch business and attack, such as figure 1 As shown, the switch CPU needs to process three types of messages: routing plane, for routing services, such as Address Resolution Protocol (Address Resolution Protocol, ARP) message; management plane, for management switch services, such as remote terminal protocol Telnet message; protocol plane A packet serves for protocol operation, such as an Open Shortest Path First (Open Shortest Path First, OSPF) packet. When there is an attacke...

Problems solved by technology

[0008] The situation that the elephant flow affects the mouse flow also occurs between two different types of packets. When the two packets are in the same priority queue, the elephant flow will eat up the main resources of the queue, especially when When there are multiple elephant streams, the resources of the queue may be exhausted, which affects the normal use of the mouse stream
