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 802.1Q protocol, that is, Virtual bridge

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

Internet Protocol Summary, Internet Protocol Today, I saw an article on network protocol on my way to work. I think it's a good job to write. Well, of course I want to keep some good stuff. I 'd like to share it with you here! This article is reproduced in the network log of Ruan Yifeng Author: Ruan Yifeng Original article: http://www.ruanyifeng.com/blog/2012/05/

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

MySQL5.6 has many new features, many of whom are interested in the global transaction ordinal function (Gtids). The reason why everyone is interested in this feature is that it's always a hassle to reconnect from the server and a new primary server, but it's easy to do after enabling the Gtids feature. However, the use of Gtids not only replaces the old binary log file/location with a separate identifier, it also uses a new replication protocol. If yo

Protocol buffers is a data description language developed by Google, similar to XML that can serialize structured data for data storage and communication protocols. At this stage of support Hold three programming languages, such as C + +, JAVA, Python. It is a binary format, much faster than using XML for data exchange. It can be used in data communication between distributed applications or in heterogeneous environments. Http://code.google.com/intl/z

First, Introduction The Protocol deals with properties and methods that act like abstract classes in Java, and types in swift implement some of the agreed properties and methods by adhering to the protocol. The protocol in Swift is declared using the Protocol keyword. The protocol
