Each layer of communication has its own unique security problems. Communication connections at the second protocol layer of the data link layer are relatively weak in terms of security. Network security issues should be addressed at multiple protocol layers for different vulnerabilities. In this article, we will focus on security issues related to wired LAN.In the communication at the second protocol layer, vswitches are key components and are also used for communication at the third protocol la

after the first two steps our Raspberry Pi has worked normally, but before actually using it to develop some column configuration and software installation, so that the development will be handy, below we introduce the common software and services1.

Hardware condition: One Camera + one FMS Server Principle: The camera collects video sources in real time and then pushes them to the FMS server. Other customers obtain video streams from FMS. Two flas are required. One is used to push the video source (that is, the sender) to the SSP server, and the other is used to obtain and play the video (that is, the receiver) from the FMS server) Server. fla keyCode: VaR cam: Camera; var VOD: Video; var

construct the video_device structure, and then call the registration function. For example, in zc301_core.c Err = video_register_device (cam-> v4ldev, vfl_type_grabber, Video_nr [dev_nr]); The Video Core layer (Drivers/Media/Video/videodev. c) provides the logout function.

Find createcamera () and add the following code to it: mPrimary->createCamera(CAMERA_NAME); mSecondary->createCamera(CAMERA_NAME); Creating the viewports Creating a viewport in this project is somewhat different from the previous tutorial. When creating a view, you must do the following: Create a view by yourself and set the aspect ratio for the camera you are

Raspberry Pi has two audio output modes: hdmi and headphone interfaces. You can switch between the two modes at any time. If your HDMI monitor has a built-in speaker, the audio can be played through the HDMI interface. You can also switch to the headset interface to use the speaker of the headset or other headset interface to play the video. If your monitor requests support from the speaker, the sound is output through HDMI by default; if not, the sound is output through the headset interface. T

forwarded. The best BPDUs here refer to the BPDUs sent by the current Root bridge. If a subordinate BPDU is received (the newly-accessed device sends BPDUs, but the device's bid is larger than the current root bridge), the device that receives the subordinate BPDU sends its own stored best bpdus to the newly-accessed device to inform its current network of root bridges, and if the received BPDUs are better, The spanning tree topology will be recalculated. When the non-root bridge has not receiv

In this example, the "View" is compared to the TV screen. Through this screen, our audience can see the scenes taken by cameras (3D objects ).
