1. Introduction to ZigBee protocol stackProtocol is a series of communication standards, both sides of the communication need to follow this standard for normal data transmission and reception. Protocol stack is a concrete implementation of the Protocol, the popular protocol

This series of articles summarizes Linux network stacks, including:(1) Linux Network protocol Stack Summary(2) Network multipart offload technology Gso/tso/ufo/lro/gro in non-virtualized Linux environment(3) QEMU/KVM Network multipart offload technology in virtualized Linux environment Gso/tso/ufo/lro/gro1. Linux Network Path1.1 Send-side 1.1.1 Application layer(1) SocketThe application layer of the various

The registration and initialization process of the pci NIC Driver is implemented. the TCP/IP protocol stack and the pci protocol stack are implemented after soft interruptions occur.0x01 reason The purpose of this study is to follow the outline below: The three handshakes, data transmission, and four handshakes are deb

reader has a general understanding of the simple call process of the SIP protocol, and will use ethereal and other packet capture tools to analyze the SIP Message structure, have a good understanding of the concepts of C pointers, linked lists, memory control, and state machines .) To apply Osip to our program, we should first look at the official documentation, which gives a detailed description of how to use the various functional components provid

Implementation of Lightweight Process Control Component Based on netty http protocol stack, netty protocol stack Today is the winter solstice, the so-called "Winter New Year", the company should also let everyone go home at five o'clock to eat dumplings and drink mutton soup, I still insist on staying in the company b

Linux Kernel protocol stack socket query cache routing mechanism, protocol stack socketIs it faster to query the route table? Or is it faster to query the socket hash table? This is not the root of the problem. The root cause of the problem is how to use the two effectively, so that the two can become partners rather t

configured. ③ Improve the correctness of ICMPv6, TCP and other protocols by calculating and processing the checksum fields. ④ Implement simple application layer protocols (such as TELNET and SNMP protocols), and use remote terminals to log on to the microcontroller system running the Embedded IPv6 protocol stack, and perform simple control and management operations. Layered and Modular Design of Embedded I

Layer in Internet protocol stack People have already discussed how to map TCP/IP reference models to OSI models. Because TCP/IP and OSI model groups cannot exactly match, there is no correct answer yet. In addition, the lower layer of the OSI model does not have the ability

1 Preface This article simply introduces the Bluetooth protocol stack, including the HCI layer, ACL link, L2CAP layer, SDP service and several common profiles that let beginners of the Bluetooth protocol stackAn overall framework for the entire Bluetooth protocol stack is

the process communication channel. In this way, mail Transmission is independent of the transmission subsystem and can transmit mail in the TCP/IP environment, the OSI transport layer, or the X.25 protocol environment.Before sending an email, you must negotiate the sender and receiver. When the SMTP service process agrees to send mail to a basic receiver, it directly delivers the mail to the receiver user

ZigBee terminology I,Attribute is a data value that reflects the physical quantity or status, such as the switch value On/Off), temperature value, percentage, and so On. II,A Cluster is a group that contains one or more attribute attributes. In short, a cluster is a set of attributes. Each cluster is assigned a unique cluster ID and each cluster has a maximum of 65536 attributes. III,Device description device description DeviceDescription refers to a part of a large target application, including

We have analyzed some protocols and the content of the protocol stack. I believe everyone understands the content of the H.323 protocol. Here we will explain the development of this protocol stack. Developing an H.323 protocol

began to learn TI's ZigBee protocol stack, wireless Dragon's data to see a lot of confusion, in the network to find many analysis of the stack of articles, first paste up, and so they have time to have a good original.Protocol stack version: zstack-1.4.3-1.2.1TI z-stack

The rise of the network and the development of the communication technology of Apsara stack have been accompanied by the development of the software radio ideology and technology. Among them, it is worth noting the content of protocol stack development. In modern digital communication systems, DSP and other digital signal processors are increasingly used in combi

Note: The content of this article comes from the Netizen God, as the study note record in this. If there is a similar, please understand;The TCP/IP protocol stack is divided into four layers: application layer, Transport layer, network, data link layer, each layer has corresponding protocol;The so-called protocol: is a

The author is called Mr. G,10 years Java research and development experience, has been in the digital, Aerospace Institute of a Research and development center engaged in software design and research and de

Panid Settings The sign of a ZigBee network is that Panid,panid is a 16-bit variable that can define 65,535 different networks of Panid numbers. We can use Panid to differentiate different ZigBee networks within the same channel. Panid is generally determined by coordinator, router and Enddevice access will be coordinator from Panid. You can also fix the Panid of router and enddevice to join a specific coordinator. This value is defined in the tools/f8wconfig.cfg of the Zstack

PPPoE (point-to-point over Ethernet, allows the Ethernet host to connect to an unwarranted access concentrator via a simple bridging device [3]) dial-up Internet, The Ppop header is 8 bytes, so the MTU of PPPoE is 1492,MSS and 1492-40=1452.So, what is the MSS for data transfer after TCP connection is established, 1460 or 1452 or 536? My understanding is the default value of 536, so to understand it? Ask for advice!3.4 Third HandshakeClient again the server's message segment, at this time the se
