连接导向式通信 Connection-oriented communication

(重定向自Connection oriented)

连接导向式通信英语:Connection-oriented communication,又称CO-mode),又译为链接导向通信预接式通信面向链接通信,是电信与电脑网络中的一种数据传输模式。连接导向式通信可以采用实体电路交换,或是虚拟电路连接来交换数据。在这种模式下,在正式交换数据之前,要先创建通信会话(communication session)或是连接,之后,串流数据在这个连接上循序发送。传输控制协定(TCP)与异步传输模式(ATM)皆属于连接导向性通信。

其优点在于,一旦创建好连接,网络流量就是固定的,不会被其他通信影响。其缺点在于需要预先创建连接,耗费的资源成本较高,无法分享网络带宽。

Connection-oriented communication 连接导向式通讯

(重定向自Connection oriented)

Connection-oriented (CO-mode) communication is a network communication mode in telecommunications and computer networking, where a communication session or a semi-permanent connection is established before any useful data can be transferred, and where a stream of data is delivered in the same order as it was sent. The alternative to connection-oriented transmission is connectionless communication, for example the datagram mode communication used by the IP and UDP protocols, where data may be delivered out of order, since different packets are routed independently, and may be delivered over different paths.
