Port mirroring is used on a network switch to send a copy of network packets seen on one switch port (or an entire VLAN) to a network monitoring connection on another switch port. This is commonly used for network appliances that require monitoring of network traffic such as an intrusion detection system, passive probe or real user monitoring (RUM) technology that is used to support application performance management (APM). Port mirroring on a Cisco Systems switch is generally referred to as Switched Port Analyzer (SPAN) or Remote Switched Port Analyzer (RSPAN). Other vendors have different names for it, such as Roving Analysis Port (RAP) on 3Com switches.
Data processing method of block chain network and related products thereof
The invention discloses a data processing method of a block chain network and a related product thereof, the block chain network comprises a plurality of block chain nodes, the plurality of block chain nodes comprise block outlet nodes, the plurality of block chain nodes carry out data interaction based on a switch, the switch has a port mirror image module, and the port mirror image module is connected with the block outlet nodes. The method comprises the following steps: receiving a first data packet sent by a switch through a port mirroring module, wherein the first data packet is obtained by mirroring an obtained network data packet related to an out-block node through the port mirroring module by the switch; performing data analysis processing on the first data packet to obtain analysis data; and detecting the out-of-block node based on the analysis data to obtain a detection result which indicates the out-of-block process of the out-of-block node. By adopting the method and the device, the accuracy of detecting and processing the out-of-block node can be improved.

Method and system for online testing of dcs network load and dual network switching performance
PendingCN122293550AAd hoc testingOnline test
This application relates to an online testing method for DCS network load and dual-network switching performance. The method includes: responding to a unit shutdown and a signal where field I / O signals are securely isolated, generating and activating a batch of temporary test points in at least one pair of controllers in the DCS for network-wide broadcasting to simulate peak network load; when the peak network load exceeds a preset load threshold, forcibly triggering a primary / backup switching operation between the DCS's A and B networks; collecting traffic data from the A and B networks via switch port mirroring; recording application layer service data within the DCS; and analyzing network switching performance indicators based on the traffic and service data. This application solves the problem of inaccurately measuring the operating status of thermal power generating units, and the network-wide broadcasting of batch temporary test points can reproduce the communication characteristics of the DCS under full load or even overload conditions.
