Therefore, CEP is always part of ESP; however, esp includes other event processing types (such as event transfer and event coordination) when these are executed on the stream rather than on the channel.An event-driven application can act as the event source, event receipt, or both. The event source generates an event for receiving the event. Note that there is no
introducing the concept of SNI er, we must first introduce some basic concepts of LAN devices.Data is transmitted in a small frame unit on the network. frames are composed of several parts and different parts perform different functions. Frames are driven by a specific network Program The software is molded, and then sent to the network card through the network card, through the network cable to reach their target machine, at the end of the target machine to execute the opposite process.
