Android USB Connections Explained:mtp, PTP, and USB Mass StorageOlder Android devices support USB mass storage for transferring files back and forth with a computer. Modern Android devices use the MTP or PTP protocols-you can choose which one prefer.To select a USB connectio
devices currently use USB-based protocols. The equipment supporting MTP on the market has Motorola's Z6, U9, E8 and so on, as well as the Sony NWZ-A81X series.

It is necessary to unify the local time of each part in the system and clock synchronization. With the widespread application of distributed simulation system and test system on the network, how to provide reli

1.PTP Models
The PTP (point-to-point) model is queue-based, and for the PTP message model its message is intended to be a message queue (queue), and the message producer always sends the message to the message queue each time it is sent. Message consumers always read messages from the message queue. Advanced Queue messages are first read by the message consumer.
architecture emerged, so JMS came out.
Here, we use Programming to Implement message transmission in the PTP model. Of course, either model is inseparable from the message server.
Because the server is based on the weblogic12c server, and the version of 12 has changed significantly compared with the previous version, to create a queue, you must first create a JMS module.

NTP, Network Time Protocol, is a time synchronization protocol defined by RFC 1305 that is used to synchronize time between distributed time servers and clients. NTP is transmitted based on UDP packets, using a UDP port number of 123.
