Record 1 1996-07-12

English

Subject field(s)
  • Data Transmission
OBS

This class introduces two new concepts. Adaptive Packet Assembly and Data Phase Optimization, both of which further enhance performance. Adaptive Packet Assembly means that the size of the packets in which data is sent between modems is altered according to the quality of the physical link. The higher the line quality, the larger the packets. Data Phase Optimization means that repetitive control information is removed from the data stream to make packets more efficient. Both techniques when combined with Class 3, yield a protocol efficiency of about 120 percent.

Domaine(s)
  • Transmission de données
OBS

Ce protocole apporte deux compléments par rapport aux versions antérieures : suppression des informations de contrôle répétitives et correction en fonction de la qualité de la ligne et de la taille des paquets contenant les données. Cette technique multiplie le débit par 1,2. À titre d’exemple, un modem de 2 400 bps pourra atteindre une vitesse de transfert de 2 900 bps.

Record 2 1996-07-12

English

Subject field(s)
  • Data Transmission
OBS

This class implements MNP basic data compression to realize a net throughput efficiency of 200 percent on average. Class 5 uses a real-time adaptive algorithm to compress data. The real-time aspects of the algorithm allow the data compression to operate on interactive terminal data as well as file transfer data. The adaptive nature of the algorithm means data compression is always optimized for the user's data. The compression algorithm constantly analyzes the user data and adjusts the compression parameters to maximize data throughput.

  • Transmission de données
OBS

Ce protocole ajoute la compression aux fonctionnalités de MNP4. Avec MNP5, le débit effectif pour le fichier transmis est doublé en moyenne. Deux techniques de compression sont utilisées :-le codage de HUFFMAN, qui consiste à coder des lettres codées en fonction de leur fréquence d’utilisation;-la méthode Run Length Encoding, selon laquelle, quand MNP5 transmet trois caractères identiques dans une trame, le quatrième correspond à un compteur enregistrant le nombre de caractères identiques qui suivent.
