Objective-c Protocol (Protocol), objectivecprotocol The Protocol is a list of methods shared by multiple classes. methods listed in the Protocol are not implemented in this class, but are implemented by other classes. To comply with a protocol, a class must implement all met

1. TCP connectionTCP (transmission Control Protocol) transmission protocol. TCP is the host-to-host layer of the Transmission Control Protocol, providing a reliable connection service, using three-time handshake confirmation to establish a connection. The bit code is the TCP flag bit, there are 6 kinds of marking: SYN (synchronous set up) ACK (acknowledgement ack

IP datagram Header highest bit on the left, recorded as 0 bit, the lowest bit on the right, recorded as a bitVersion:4 bits, refers to the IP protocol version of the current IP protocol version number is 4 (that is, IPV4)Header Length:4 bits, the maximum value that can be represented is 15 units (4 bytes in one unit) so the maximum of the first ministerial degree of the IP is 60 bytesDifferentiated Services

When defining a protocol, it is useful to declare one or more association types as part of the protocol definition. An association type provides a placeholder (or alias) for a type in the protocol, and the actual type it represents is not specified until the protocol is accepted. You can specify the association type by

　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 transmi

The routing information protocol (RIP) is one of the earliest and most basic protocols in the routing protocol. Although its current use is gradually unable to meet our network construction needs, we still need to fully master this protocol as a learning basis. Like all protocols, the RIP Protocol is used to distribute

Preface: Because OBJECT-C does not support multiple inheritance, it is often replaced with protocol (protocol). The Protocol (protocol) can only define a common set of interfaces, but cannot provide a specific implementation method. That is, it only tells you what to do, but specifically how to do it, it does not care.

--> 　　核心提示：-->With the development of the IP network to the multi-service network, especially the development of VoIP in recent years, it is inevitable to transmit signaling messages in the IP network. But in the IP network cannot provide high-quality transmission services like mtp3 and ATM, so the ITU-T proposed an improved version of sscop-sscopmce in Multi-link and non-connection environment ), it is used to transmit signaling messages in an IP-based network. However, compared with sscop, ssc

NetBIOS protocol (NetWork Basic Input/Output System). This protocol is developed by IBM and is mainly used for the small LAN of dozens of computers. The NetBIOS protocol is an Application Programming Interface API that can be used by a program on the LAN.

TCP (transmission Control Protocol, transmission Protocol) is a connection-oriented protocol,In other words, a reliable connection must be established with each other before sending or receiving data.A TCP connection has to be three "conversations" to build, and the process is very complex and simply describes the simple process of three conversations: A
