. From China's decades of application of transmission technology, the FDM-TDM-TDM FDM is the route to go. The beginning of the wire, coaxial cable used are FDM simulation technology, that is, the frequency division multiplexing technology, each voice bandwidth of 4KHz, each voice occupy the transmission medium (such as coaxial cable) a section of bandwidth; PDH, SDH system is a TDM baseband digital signal transmitted on optical fiber, each voice rate is 64kb/s While WDM technology is the optical

In Linux based on bacnet-stack-0.8.0 engineering, bacnet protocol packet is sent through wireless network card. linux environment is Ubuntu 12.04 + USB wireless network card (09 annual production of mercury MW54U, relatively old) 2. after compiling the target file in the normal way, 3. run the program in the/bin directory: execute the following two steps before r

other data bits. Basic functions can be used to have the corresponding extension.Operation (target) can also be extended, the common default operation has accept and drop, the extension of the log, reject, etc., users can also implement their own. There are two other defaults that queue and Return,return implement functional calls between the rules, and queue implements packet queuing. These operations also correspond to specific modules: Nft_queue.ko, Nft_reject.ko, Xt_log.ko, Nft_log.ko, and

characteristics of object-oriented programming, can solve practical problems by using object-oriented design idea Check the content of the exam on the PTA platform and complete the exam. The end of the review to the end of the last review you wrote all the code (including the test part of the code) all submitted to the code cloud. Class Practice section on the code cloud to create the name of their own name of the project title _ Classroom Exercise Two, such as "16012021 three

Network Engineering Experiment 2 Experiment Name: Login switch and VRP (Comware) Use (Preview part) 1. Review the basic principles of the switch, and then briefly answer the following questions: (1) what is the frame forwarding algorithm of a vswitch? (2) How does a vswitch create its MAC address table? 2. Briefly describe how to log on to the vswitch through the Console port. 3. Briefly describe how to log

The essential difference between a post and a GET request method:First: Get is used for information acquisition, it is secure (here the meaning of security refers to non-modified information), and post is used to modify the resources on the server requestSecond: The data for the GET request is appended to the URL, and the post submits the data to the body of the HTTP message entity, so the security of the post is higher than the security of the GetThird: For the POST request data volume than get

the kernel's EBPF syntax and registers are complex, similar to real assembly code.So why does the kernel have to go through the trouble of implementing such an engine? Because it's lightweight, secure, and portable. Because it is intermediate code, portability does not have to be said, but using kernel modules to invoke the kernel's function interface is generally portable, so this is not a very important reason. EBPF code in the implementation of the process is strictly restricted to prohibit
