Monitoring | Statistics | Compression
Inbound Pre-Decompression
The total number of bytes of all incoming data before any of it is decompressed.
Inbound Post-Decompression
The total number of bytes of all incoming data after decompression.
Ratio
The ratio of Inbound Post-Decompression to Inbound Pre-Decompression.
L2TP/PPTP Using MPPC
This table shows statistics for L2TP and PPTP data compression using the MPPC compression protocol.
These MPPC statistics use the following distinctions. (See Figure 15-19.) All data transmitted can be
divided into two groups: data intended for compression (A) and data that is not intended for compression
(B). Of the data intended for compression, some of it actually compresses (A1) and some does not (A2).
(The compression process would actually cause certain data to expand, so this data is left
uncompressed.)

Resets Received
The total number of reset requests received from the remote peer.
Resets Sent
The total number of reset requests sent to the remote peer.
Outbound Pre-Compression
The total number of bytes of outbound data intended for compression. (“A” in Figure 15-19.)
