- Discard Protocol
-
-
-
-
- This RFC specifies a standard for the ARPA Internet community. Hosts on
- the ARPA Internet that choose to implement a Discard Protocol are
- expected to adopt and implement this standard.
-
- A useful debugging and measurement tool is a discard service. A discard
- service simply throws away any data it receives.
-
- TCP Based Discard Service
-
- One discard service is defined as a connection based application on
- TCP. A server listens for TCP connections on TCP port 9. Once a
- connection is established any data received is thrown away. No
- response is sent. This continues until the calling user terminates
- the connection.
-
- UDP Based Discard Service
-
- Another discard service is defined as a datagram based application on
- UDP. A server listens for UDP datagrams on UDP port 9. When a
- datagram is received, it is thrown away. No response is sent.
