互联网是一个packet switched network • Host H1 wants to send a packet to H2 1. Transmits it to the nearest router (A) 2. The packet is buffered while it is arriving, and the checksum is verified 3. If valid, the packet is stored until the outgoing interface is free 4. The router...
Total Length(IP Packet 的总长度)(16bits):最大长度为 65535Bytes(2^16-1)。 Identification(IP Packet 唯一标识)(16bits):在 IP Fragment and Reassembly(分片与重组)中,用于标识多个分片来自同一个 Packet,以此进行重组。 IP Flags(标志位)(3bits):标识 IP Packet 是否被分片。 MF(More Fragments):为 1...

RPR(Resilient Packet Ring)协议是一个工作在OSI(Open Systems Interconnection)协议栈的数据链路层的介质访问控制协议,主要应用在城域网中。RPR有4种帧格式,包括:基本数据帧、控制帧、公平算法帧、Idle帧。 RRPP帧 RRPP(Rapid Ring Protection Protocol)是专门应用于以太网环的链路层协议,是华为私有协议。
快递的运输单元叫包裹(packet),网络借鉴了这种说法。不过中文翻译过来不叫“包裹”,而叫分组(packet)(是不是瞬间逼格提升 n 倍)。 每一层的分组都有它自己的特定名字(否则每层都叫分组就很容易混淆了): 物理层严格意义上不能叫“分组”了 所以以后听到说“TCP 分组”和“TCP 报文段”不要再纠结它俩到底...
the datagram is delivered to the protocol module specified by the protocol field in the IP header. If the datagram is not destined for this IP layer, then (1) if the IP layer was configured to act as a router the packet is forwarded (that is, handled as an outgoing datagram as describ...
aA packet with a source IP address of 192.168.2.4 and a destination IP address of 10.1.1.4 arrives at the HokesB router 一个小包以192.168.2.4来源IP地址和10.1.1.4目的地IP地址到达在HokesB路由器[translate]
That’s one reason that IP addresses are so important. Because every packet includes the IP address for its origin and destination, the internet can make sure that all packets reach the right destination. DNS servers The Domain Name System (DNS) makes the modern internet possible. The DNS pai...
