What is SMB SMB, namely "Server Message Block" server information block, is a network file sharing protocol. It can be used for Web connection and information communication between client and server, allowing applications and end users to access file resources from remote file servers. SMB communication protocol is an agreement form ...

An introduction When using wireshark, one of the most frustrating things is filtering out what you need from a large number of data packets. In particular, when we need to analyze the protocol for a particular program, it's perfect to have a process name as a filter. I found an implementation when I checked the materials online, but the versio ...

Tensorflow 2.0 - FaceNet network principle and code analysis (I) - model principle and backbone network FaceNet is actually a general face recognition system described in the preface: deep convolution neural network (CNN) is used to map images to European space. Spatial distance is directly related to image similarity: different images of the ...

Process Overview The basic principle of network communication between client and server is as follows. Message oriented middleware may be added to a more complex architecture. For the server, the communication process is as follows: 1,call socket Function create listener socket 2,call bind Function will socket Bind to a IP And port nu ...

preface In the last article ndnSIM learning (8) -- ndn-simple.cpp of examples analyzes each function line by line In, we analyze the underlying principle of the whole ndn-simple.cpp. As the core, it is naturally the working process of the whole network: how do consumers send interest packets? How do producers return packets based on intere ...

Cerebral fissure In the high availability (HA) system, when the "heartbeat line" connecting two nodes is disconnected, the HA system, which is originally a whole and coordinated action, will be split into two independent individuals. Because they lost contact with each other, they all thought it was the other party's fault. The HA ...
