TCPIn this paper, we focus on passive measurements of TCP traffic. We propose a heuristic technique to classify TCP anomalies, i.e., segments that have a sequence number different from the expected one, such as out-of-sequence and duplicate segments. Since TCP is a closed-loop protocol ...
When the remote side of a TCP socket shuts the socket down for writing, all unread bytes on a passive socket which have been received by gen_tcp are immediately discarded and no longer accessible. To Reproduce The following escript demonstrates the issue: listen()->{ok,Listener}=gen_tcp:lis...
tcpaccept - Trace TCP passive connections (accept()). Uses Linux eBPF/bcc. SYNOPSIS tcpaccept [-h] [-T] [-t] [-p PID] [-P PORTS] [--cgroupmap MAPPATH] [--mntnsmap MAPPATH] DESCRIPTION This tool traces passive TCP connections (eg, via an accept() syscall; connect() are activ...

NAT will modify the IP protocol and TCP protocol header, and thus it is difficult to effectively check the indentity of the sending packets and receiving packets in a passive way to measure one-way-delay. In this paper, IP protocol and TCP protocol headers of captrued packets which was modi...
One challenge is that the majority of connections on mobiles are short-lived TCP connections, where a significant portion of data exchange is within the slow start phase. In this paper, we propose a novel method that passively estimates the currently available bandwidth by monitoring the minimal ...
Since TCP sender always sends packages that belong to the same round together, there is a "gap" between two rounds of sending. PRE can find "gap" between two rounds, and so (hat can estimate RTf in a passive mode. Base on PRE, passive TCP performance measurement can be deployed in ...
A TCP连接建立:TCP的连接建立过程又称为TCP三次握手。首先发送方主机向接收方主机发起一个建立连接的同步(SYN)请求;接收方主机在收到这个请求后向发送方主机回复一个同步/确认(SYN/ACK)应答;发送方主机收到此包后再向接收方主机发送一个确认(ACK),此时TCP连接成功建立。反馈...
