Brief introduction
WebSphere MQ Low Latency Messaging (hereinafter called MQ LLM) is an IBM messaging product that delivers high-capacity, low-latency, reliable messaging on a variety of network architectures, designed to be published in a message-oriented middleware/ Subsc
platforms, provides consistent communication standards and application development, and ensures reliable, cross-platform information transmission and data exchange in distributed computing networks. It is based on the storage-forwarding mechanism of message queues and provides a unique asynchronous transmission mechanism, which can realize application integration and data exchange based on message transmission and asynchronous transaction processing.
With its unique security mechanism, simple
asynchronous transmission mechanism, which can realize application integration and data exchange based on message transmission and asynchronous transaction processing.
With its unique security mechanism, simple and fast programming style, exceptional stability, scalability and Cross-platform, and powerful transaction processing and messaging capabilities, the IBM messaging middleware
provides the unique asynchronous transmission mechanism, which can realize application integration and data exchange based on message transmission and asynchronous transaction processing.
IBM message Middleware MQ is the most market-share messaging middleware product in the industry with its unique security mechanism, simple and fast programming style, excellent stability, scalability and cross-platform, a
called deferred message communication , that is, after a message is emitted from one end, it enters a container for temporary storage, and when a certain condition is reached, it is sent to the other end by this container. a specific implementation of this container is Message Queuing .2-2. Knowledge structureMessage Queuing is the same as the RPC that has been introduced: either RPC or Message Queuing they are built on the network IO model (we've covered a variety of network IO models).

I want to write a summary for a long time, but I have been busy and have no time to calm down and do such a thing.
I once told my eldest brother Qin that I didn't have the open source spirit, but because there were too many things an
. It occurs when the client sees "message sending failed" but the other person receives the message because the client-issued message server has received and forwarded successfully, but the client did not receive the server's answer packet due to the network reason. We use TCP based data Transfer protocol when we file transfer, because we need to ensure the order of data transmission arrives, and we must ensure that there is no loss of data.

During this time, the company had to learn more about XMPP-based chat and social networking software. I searched for some information and summarized it. .
Based on the open-source XMPP instant communication protocol, the C/S architecture is used to connect to the server through the GPRS wireless network using the TCP protocol, and the open-source openfn 'e server is set up as the instant
Recently, when I was writing an Instant Messaging Server, I encountered a dilemma about session design in communication protocols.
First, let's talk about some existing protocol designs:
1. MSN, sip, fetion (SIP)
In this Protocol, both parties need to establish a session. First, a session creation request is sent. The following uses a sip conversation as
