WebThe term TCP packet appears in both informal and formal usage, ... For more efficient use of high-bandwidth networks, a larger TCP window size may be used. A 16-bit TCP window size field controls the flow of data and its value is limited to 65,535 bytes. Since the size field cannot be expanded beyond this limit, a scaling factor is used. TCP protocol operations may be divided into three phases. Connection establishment is a multi-step handshake process that establishes a connection before entering the data transfer phase. After data transfer is completed, the connection termination closes the connection and releases all allocated resources. oracle btree索引

WebMar 6, 2024 · Maximum Transmission Unit (MTU) MTU is the largest packet or frame size, specified in octets (eight-bit bytes) that can be sent in a packet- or frame-based network. The internet’s transmission control protocol (TCP) uses the MTU to determine the maximum size of each packet in any transmission. WebIn networking, a packet is a small segment of a larger message. Data sent over computer networks*, such as the Internet, is divided into packets. These packets are then recombined by the computer or device that receives them.
