Technical description for port 843:
The port 843 is used by the Adobe socket policy file server. This is used to distribute socket policy files. Socket policy files are used to authorize connections to clients. This function is used to facilitate streaming media from the Internet. The service is also used by later versions of the Adobe Flash Player to manage incoming media.
These socket policy files are distributed from the TCP port 843 to listen for requests to access the system. The same port is used to send the socket policy files to request clients over the Internet. Adobe has applied to the Internet Assigned Numbers Authority (IANA) to reserve the port 843 for the socket file server.
The port 843 is standardized as the socket file server port so that it will be the default port used during set-up.
If the port 843 is used as the default port for the server, a socket meta-policy can be implemented so that the socket policy rules can be implemented faster.
