information. Transport Layer: ensures data reliability and efficiency at the source and target nodes. ① 802.15.4/ZigBee protocol The IEEE 802.15.4 standard is dedicated to low-speed networks, and ZigBee is built on the IEEE 802.15.4 standard. The IEEE 802.15.4 protocol specifies the physical layer and MAC layer of the network; The ZigBee protocol specifies the n

address, and destination port number, it can also be all packets sent to a certain network segment. 10.1.2 priority in L2 VLAN frames the priority in L2 frames is specific to VLAN frames because normal L2 frames do not carry priority fields. The priority in a VLAN frame is what we call the 802.1p priority (defined by the IEEE 802.1p Protocol). It is located in the "PRI" subfield of the "802.1Q Tag" field in the VLAN frame, as shown in 10-1. Figure 10

Achieving a sound fairness mechanism is very helpful for the RPR loop to quickly respond to sudden changes in data traffic; Supports unicast, multicast, and broadcast: You can map unicast, multicast, and broadcast data packets based on IEEE 802.3mac addresses to the node's rpr m

ObjectiveAt present, China vigorously promote the internet of Things is the main battlefield of ZigBee applications, the Internet of things through intelligent sensing, recognition technology and pervasive computing (I also specifically applied for a domain name PSJS.VIP), ubiquitous network fusion application, known as the second computer, the world's information industry after the development of the third wave. If you want to make a difference on the internet of Things, now open the door to Zi

circuit, determine whether the MAC address of the datagram and its own to determine whether to receive the datagram.3.2.4 EthernetIn Ethernet, if more than one host needs to communicate at the same time, then these hosts who first win the transmission media (communication lines),Who gets the right to send data, the technology is called bus contention media access .There is also a token-network technology, which takes each of the tokens in turn to gain access to the media.Ethernet Specification:

Chapter Review:"TCP/IP Detailed Volume 1: Agreement" 1th Chapter Overview-Reading Notes1. IntroductionAs can be seen from figure 1-4, in the TCP/IP protocol family, the link layer has three main purposes:(1) send and receive IP datagram for IP module;(2) send ARP request and receive ARP reply for ARP module.(3) send Rarp request and receive Rarp reply for Rarp.TCP/IP supports a number of different link layer protocols, depending on the hardware used by the network, such as Ethernet, Token Ring,

to intrude than WEP. Therefore, if there is a high requirement on data security, you must use the WPA encryption method (Windows XP SP2 already supports the WPA encryption method ). As an upgraded version of IEEE 802.11's general encryption mechanism WEP, WPA is more secure than WEP, mainly reflected in identity authentication, encryption mechanism and packet inspection, it also improves the management capability of wireless networks. Comparison of W

That standard handles the sign in a manner similar to sign-and-magnitud

I. Overview of ECDSAElliptic Curve Digital Signature Algorithm (ECDSA) is the simulation of digital Signature Algorithm (DSA) using Elliptic curve cryptography (ECC). ECDSA became the ANSI standard in 1999 and became the IEEE and NIST Standard in 2000. It was accepted by ISO in 1998, and some of its other standards are also considered in the ISO. Unlike the common discrete logarithm problem (discrete logarithm problem DLP) and the large number decompo

The IEEE Spectrum website publishes its annual ranking of programming languages, which is the fourth edition of the list of programming languages they have published.It is understood that the sorting of IEEE Spectrum is a synthesis from 10 important online data sources, such as Stack Overflow, Twitter, Reddit, IEEE Xplore, GitHub, etc., ranking in 48 languages.Un

security of building wireless networks, the compatibility of wireless devices, and so on. Today we are going to talk about how the office realizes the Wireless network environment. Range of wireless signal coverage Just now we talked about the advantages of using wireless network, we also want to talk about some of its shortcomings, first of all, the wireless network coverage is one of the factors we should consider. Speaking of the signal coverage, first we need to see its transport protocol,

frames, and other types of Mac control frames use different opcode values, which are not explained in detail here. Later, we will talk about a PFC frame similar to pause, where the value of the field in the PFC frame is 0x0101. The Mac control parameters domain needs to be parsed according to the type of mac control opcode. For pause frames, the field is a 2-byte unsigned number with a range of 0~65535. The time unit for this domain is Pause_quanta, and each pause_quanta is equivalent to 512 bi

USB Wireless card which is good? To choose a good USB wireless network card standard: 1. Wireless Standard Currently, wireless LAN devices in the market mainly support IEEE 802.11g and IEEE 802.11n two standards. Network adapters that support IEEE 802.11g+ standards, with a maximum transfer rate of 108Mbps, network adapters that support

(MBS) is a mobile broadband design program organized by some companies and schools in the European Commission. Its physical layer is based on the TDMA variant of most 2G telephones, and the higher level is based on ATM. Previous generations of mobile communications are mainly used for telephone calls, or some other business such as SMS, while MBS is to separate various forms of services. It is a large data channel facility that can be used separately for various forms of service. It is estimat
