我们学过TCP协议,知道TCP三次握手中的第一次生成的seq是随机生成的,接下来的数据的seq都是在首seq的基础上递增的,但是我们在收到数据后进行逻辑处理的时候,为了方便后续开发,我们引出了三个概念:初始序列号(initial sequence number)、相对序列号(relative sequence number)绝对序列号(absolute sequence number) 初始...
Many techniques were already developed using the Transmission Control Protocol (TCP) headers. Among the schemes in hiding information in the TCP header, the Initial Sequence Number (ISN) field is the most difficult to be detected since this field can have arbitrary values within the requirements ...
A 'Sequence Number Space' refers to the range of possible sequence numbers that can be assigned to frames in a communication protocol. It is limited by the size of the header field used to specify sequence numbers, leading to the need for reusing numbers or wrapping around when the maximum ...
TCP utilizes a number of flags, or 1-bit boolean fields, in its header to control the state of a connection. The three we're most interested in here are: SYN- (Synchronize) Initiates a connection FIN- (Final) Cleanly terminates a connection ...
A TCP header looks like the following: The below explanation explains how a connection is established between two hosts at TCP level. This is known as three way handshake. This handshake is required before any kind of data can be sent in each direction. Once the connection is established, da...
The TCP header includes sequence and acknowledgment numbers for reliable delivery. TCP can also use the sliding window principle. The sliding window algorithm allows a buffer to be placed between the application program and the network data flow. Data received from the network is placed into this ...
