Some Technical Definitions

The OFTP Commands
To control the communication of data, OFTP provides a set of signals which indicate when a message can be sent to the receiving system. These signals are called the OFTP commands. Each command serves a different function, not all of which will be used in every transmission – the signals used will be dictated by the nature of the communication session itself.

Files supported by the OFTP
OFTP allows the transfer of different types of files. These include fixed length records, variable length records, unformatted files and text format files.

Access Methods and the OFTP
OFTP supports TCP/IP, ISDN, direct native access to the X.25 network, dial-up connections using a combination of recommendations X.28, X.3 and X.29. It provides both error detection and recovery procedures for the latter. As well, ISDN connection to X.25 networks can be used in accordance with recommendation X.31.
OFTP is perfectly adapted to ENX extranet; certified ENX operators offer various types of connections (isolated station with IPsec customer, connection by STN or ISDN: up to 64 kbits, small LAN, LAN...). See ENX file...

Transport Layer Security (TLS) and its predecessor, Secure Sockets Layer (SSL), are cryptographic protocols that provide communications security over the Internet. Wikipedia

Strong Authentication
Strong authentication is a mechanism to ensure mutual identification of two network partners. This mechanism is based on the personal character of the private key.

File Services
Services file, defined by the protocol version 2, provide optional services:

  • Encryption (file-level, complementing the SSL encryption)
  • Fiile ignature (including EERP and NERP)
  • Compression (high compression further compression OFTP V1)
