Put these three protocols together because the three protocols are on the same level, the ARP protocol is used to locate the target host's Ethernet NIC MAC address, and the IP hosts the message to be sent. The data link layer can get the data transfer information from ARP, and the data to be transmitted from IP.1.IP protocolThe IP protocol is the core of the IP protocol

IP Datagram
IP is the core protocol in the TCP/IP protocol family. All TCP, UDP, ICMP, and IGMP data are transmitted in the IP datagram format. The IP address only provides the best-effort transmission service. If an error occurs, the IP address will lose the data and send an ICMP message to the source. In addition, IP datagram can not be accepted in the sending order.
The IP datagram format is as follows:
Video image transmission has the following characteristics: 1 requirements for small transmission delay, high real-time, 2 transmission flow, requiring high transmission efficiency; 3 allow transmission errors or data loss on certain programs. According to the above characteristics, it is more ideal to use UDP protocol to transmit video relative to TCP protocol.
UDP is the abbreviation of User Datagram
Mobile device Management (MDM) and OMA (OTA) DM Protocol Wizard (ii)--WAP Protocol (1)On the "Mobile Device Management (MDM) and OMA (OTA) DM Protocol Wizard (i)"16. Can I access WiMAX devices directly from the Web server?See "WAP Protocol (1)--6th WAP Network Deployment" in this article17. Can I use TCP instead of WDP
First, the introduction
The Protocol deals with properties and methods that act like abstract classes in Java, and the types in swift implement agreed properties and methods by complying with the protocol. The protocols in Swift are declared using the Protocol keyword. The protocol in Swift also has a very interesting

This document is translated from: Http://redis.io/topics/protocol.
The Redis protocol compromises between the following three goals: ease of implementation can be efficiently analyzed by computer (parse) can easily be read by humans to understand the network layer

The web point-to-point program transmits data, is the HTTP protocol or TCP/IP protocol TCP/IP protocol and HTTP protocol what is the difference, two Web program point-to-point transmission data, you will choose that one. Today on the Internet to see such an interview topic, triggered a series of search data, review
TPC/IP Protocol is a Transport layer protocol, which mainly solves how data is transmitted in the network, and HTTP is the application layer protocol, which mainly solves how to wrap the data. regarding the relationship between TCP/IP and HTTP protocol, the network has a relatively easy to understand: "When we transmit
SIP (Session Initiation Protocol) Conversation Initiation Protocol is an application layer control (signaling) protocol for network telephony and conferencing. It is mainly a multimedia communication protocol based on IP network. It can realize the signaling functions are also using RTP as a media transmission
This paper mainly introduces the implementation of the 802.1Q VLAN protocol in the Ethernet switch, and some basic contents of the 802.1P protocol, details of the implementation of the two Protocols, and reference data of the 802.1Q and 802.1P protocols.
First, 802.1Q protocol

A host that communicates in the same network (which is not specifically referred to as an Ethernet network) must have the MAC address of the target host to correctly send the data to the target host, so how to know the MAC address of the target host. Can be passed through the ARP protocol. The ARP protocol is used to obtain the corresponding MAC address of the destination IP address, that is, the ARP
Today, a customer response, Remote Desktop can not connect, I looked, ping is normal, telnet a remote port, but also can connect, but the remote Desktop is always not connected, first to help him restart a bit. After the reboot, the remote can log in, went to check the server logs, and found such an error:
The RDP protocol component x.224 found an error in the protocol stream and interrupted the client c
different physical machines are consistent.
In order to solve this distributed consistency problem, predecessors summed up many typical protocols and algorithms during the repeated trade-offs between performance and data consistency. Among the more notable are the second-order commit protocol (two Phase commitment Protocol), the Sankai commit protocol (both Phas
