以太网帧格式 / Frame Format 下面介绍交换机如何处理 PDU(Protocol Data Unit,协议数据单元)。 所有的以太网帧都基于一个共同的格式。 帧检验序列/循环冗余检验 最后一个字段 FCS(Frame Check Sequence)提供了对帧完整性的检查。方法是:Cyclic Redundancy Check (CRC)循环冗余检验。这篇文章介绍的很好,在这里引用...
PPP Protocol Frame Formats 123 4 PPP General Control Protocol Frame Format and Option Format PPP Field Compression PPP uses the HDLC basic framing structure, which includes two fields that are needed in HDLC but not in PPP due to how the latter operates: theAddressandControlfields. Why bother ...

Figure 32: PPP General Frame Format All PPP frames are built upon the general format shown above. The first three bytes are fixed in value, followed by a two-byteProtocolfield that indicates the frame type. The variable-lengthInformationfield is formatted in a variety of ways, depending on ...
The Transmission Control Protocol (TCP) is intended for use as a highly reliable host-to-host protocol between hosts in packet-switched computer communication networks, and in interconnected systems of such networks. Packet Format Figure 4-1TCP Header Format ...

在网络通信中,TCP(传输控制协议/TransmissionControl Protocol)是一种面向连接的、可靠的、基于字节流的传输层通信协议。在视频流传输领域,TCP的使用尤为重要,因为它能够提供稳定可靠的数据传输,确保视频数据完整无误地到达接收端。本章将深入探讨使用TCP传输视频流的工作原理、优势、挑战以及解决方案。
TheNetwork Interface layer(also called the Network Access layer) is responsible for placing TCP/IP packets on the network medium and receiving TCP/IP packets off the network medium. TCP/IP was designed to be independent of the network access method, frame format, and medium. In this way, TCP...
