NDM Vs FTP

Recently i have come to know about NDM protocol . NDM was designed for File transfer between Mainframe systems. Later  on it was used for  other computers . It best suitable for  large files.
It offer various features like data compression and checkpoint restart .
given below are the few differences between NDM and FTP .

NDM offers for logging, audit, and control features.

FTP does not have elaborate processes for logging and auditing. 

NDM is an asset when dealing with large data packets through its fully automated feature.

FTP requires thorough follow-up of the processes for file transfers and downloads. 

Data security is guaranteed with NDM which offers encryption.

FTP has the encryption option desired for improved data security.

NDM compresses data and therefore uses a low bandwidth.

FTP does not compress data and uses a higher bandwidth.

The checkpoint restart feature is offered in NDM.

FTP does not allow for checkpoint restart. 

NDM offers pre- and post-processing features.

FTP only has post-processing features.

NDM later was taken by IBM . It is  now known as CONNECT:DIRECT 

ONNECT:Direct (NDM)is a product of Sterling Commerce www.stercomm.com. It is a product designed to automate and manage the exchange of files between two computers. Some of the major differences between the two:

• CONNECT:Direct provides logging, statistics. and audit control features.
• CONNECT:Direct has a built-in scheduling system for automating file transfers.
• CONNECT:Direct manages the file transfer process once it has been submitted.
• CONNECT:Direct can use both TCP/IP and SNA networking protocols as well as direct channels between computers.
• CONNECT:Direct has batch, CICS, ISPF, and web-based interfaces.
• CONNECT:Direct has its own scripting (i.e. process) language.
• CONNECT:Direct has pre- and post-processing features.
• CONNECT:Direct can be monitored with SNMP and/or other automation tools.
• CONNECT:Direct allows you to track what is happening while a transfer is happening, as well as tracking the final status of the file exchange process.
• CONNECT:Direct works with all data types (QSAM, VSAM, PDS, binary).
• CONNECT:Direct can interface with your JES Spool output.
• CONNECT:Direct can interface with your email server.
• CONNECT:Direct can scan directories for the presence of a file, and then initiate a transfer process upon receipt of the file within that directory.
• One vendor means that there are no compatibility issues.
• Check-point restarts of large transfers.
