The Out Of Brower transport layer protocol uses out-of-band (OOB) to send important data. If the communication party has important data to notify the other party, the protocol can send the data to the other Party quickly. to send the data, the Protocol generally uses another channel instead of the same channel as normal data. the socket mechanism in Linux supports sending and receiving out-of-band data through low-layer protocols. however, the TCP protocol has no real out-of-band data. to send important protocols, TCP provides a mechanism called urgent mode. set the URG bit in the Data Segment of TCP to enter the emergency mode. the recipient can take special measures for the emergency mode. it is easy to see that data is not blocked in this way. You can capture sigurg signals in our server programs to accept the data in time or use the Recv function with OOB flag to accept the data. intel active management technology (Intel AMT) is OOB.

Sliverlight is a new feature of Microsoft Silverlight. sliverlight allows independent browsers to access specific file directories in the system. Like a general desktop program, sliverlight can minimize the number of drag messages and install shortcuts in the pop-up window.
The following is a demo of Silverlight OOB, which includes installation, update detection, system tray, and opening Word by calling COM components.
