rabbitmq ack

In the TCP protocol Before the communication has to go through three times handshake, the requester sends out a SYN signal request connection, the other party receives and accepts when will send an ACK message.An ACK is the meaning of a response. What is an ACK attack?Land Attack attack: In land attacks, hackers use a specially crafted SYN packet-its original add

message, and when ACK mode is enabled, the switch cannot find the queue and returns an error. There are four types of switches: Direct, topic, Headers and fanout direct:direct types behave as "match first, then deliver." That is, when the binding is set to a Routing_key, the routing_key of the message matches, the switch is delivered to the bound queue. Topic: Forwarding messages by rules (most flexible) Headers: Set header attribute parameter type S

when using the TCP/IP protocol for communication, send first transfers copy data to the Protocol cache, the protocol then sends the data to the receiver, and then waits for the ack . If ack is not received, the Protocol resends data, in this process, send is always waiting, until you receive ack , when the Protocol receives

For system administrators or programmers, grep is probably the most popular tool when they need to search for specific text or patterns in a directory with complex configurations or in a large source code tree. If grep is one of your favorite tools, you may prefer ack. Ack is a Perl-based command line tool similar to grep, but the search speed is faster and the capability is stronger than grep. Especially w

When using the stomp package (such as PHP Python Ruby) in some language environments, the following problems may occur: Unexpected ack received ed for message-ID This may be caused by two reasons. 1. No Ack is sent in order, which leads activemq to think you are sending an error. Solution 1) issue ack in order 2) set it to the independent confirmat

Rfc3261 and rfc3262 define CSeq and rack respectively, but they often do not understand their meaning during the application process, leading to errors.

The serial number (sequence number) in a TCP packet is not numbered by the packet segment. Instead, all the data transmitted during the connection life cycle is treated as a byte stream, the serial number is the number of each byte in the entire byte stream. A tcp data packet contains data of multiple byte streams (that is, data segments), and the data size of each TCP data packet is not necessarily the same. During the three-way handshake of a TCP connection, both parties have determined the in

TCP Header TCP is a protocol supported by the transport layer in the TCP/IP protocol stack, and TCP has its own header information.The TCP header information is shown in the following table: 　　 TCP is a connection-oriented, reliable transport protocol. This reliable transmission function is achieved by 32-bit serial number and 32-bit acknowledgment sequence number. the flag bit of the TCP header There are six flag bits in the TCP header: Urg/ack/psh/
