论文摘要
运输协议的主要责任是支持两个端到端实体之间的通信。这些实体可以是主机或设备，例如路由器，防火墙等。运输协议提供了在这两个端到端设备之间几乎可以循环的途径的机制。传输协议有两种类型：面向连接和无连接。顾名思义，以连接为导向，需要其他工作来建立连接，并在数据包重新排序，拥塞控制，可靠的数据包方面提供可靠性。另一方面，无连接传输协议适应，发送和忘记机制。它的全部目的是交付数据报，而不必担心其交付。 TCP和UDP有两个主要协议，分别用于以连接为导向和无连接服务。作为以连接为导向的协议，TCP提供了可靠的端到端连接，并具有拥塞控制机制，以避免接收器侧缓冲区溢出。
Main responsibility of a transport protocol is to support communication between two end-to-end entities. These entities can be hosts or devices, such as routers, firewalls etc. Transport protocol provides mechanism to have a virtually circuited route between these two end-to-end devices. Transport protocol are of two types: Connection oriented and connection-less. As these name suggest, connection oriented requires additional work of setting up connections and provide reliability in terms of packet reordering, congestion control, reliable delivery of packets. On the other hand connectionless transport protocol adapts, sends and forgets mechanism. Its entire purpose is to deliver the datagram without having to worry about its delivery. There are two major protocols, TCP and UDP, used for connection oriented and connection-less services respectively. Being a connection oriented protocol, TCP provides a reliable end-to-end connection and have congestion control mechanisms to avoid buffer overflow at the receiver side.
