In this case, the text is exact and not left to the particular implementation; it must read: MARK yyyy = mmmm where yyyy is User-process data stream marker, and mmmm server's equivalent marker (note the spaces between markers and "="). 120: Service ready in nnn minutes. 125: Data connection already open; transfer ...
Below is a list of FTP commands that may be sent to a File Transfer Protocol (FTP) server. It includes all commands that are standardized by the Internet Engineering Task Force (IETF) in RFC 959, plus extensions. Note that most command-line FTP clients present their own non-standard set of commands to

Another approach is for the NAT to alter the values of the PORT command, using an application-level gateway for this purpose.
Round-robin DNS is a technique of load distribution, load balancing, or fault-tolerance provisioning multiple, redundant Internet Protocol service hosts, e.g., Web server, FTP servers, by managing the Domain Name System's (DNS) responses to address requests from client computers according to an appropriate statistical model.
to use a single TCP/IP (usually encrypted) connection per accessed server domain instead of 2 to 8 TCP/IP connections; to use one or more bidirectional streams per TCP/IP connection in which HTTP requests and responses are broken down and transmitted in small packets to almost solve the problem of the HOLB (head-of-line blocking).
