• Enable MPPC - When selected, enables Microsoft Point-to-Point Compression. The
MPPC scheme is a means of representing arbitrary Point-to-Point Protocol (PPP)
packets in a compressed form. The MPPC algorithm is designed to optimize processor
utilization and bandwidth utilization in order to support a large number of simultaneous
connections. The MPPC algorithm is also optimized to work efficiently in typical PPP
scenarios (1500 byte MTU, and so on).
