Hi All, After reviewing draft-ietf-ippcp-protocol-01.txt, I have the following feedback: 1) In section 2.2., paragraph 4, what kind of compressibility test (V.42bis) is suggested (referred to)? My understanding is that the example "compressibility test" provided is part of the algorithm. In which case It seems to me that this test would not be "implementation dependent", rather "algorithm dependent". Anyway, I don't understand how this approach would work for other algorithms, such as LZS or MPPC? It seems to me that the non-expansion requirement (section 2.2., paragraph 3) covers this issue, so the text can be deleted. 2) Sorry for not being up to date, but why the change from 32-bits to 16-bits for CPI? Will this scale well for large routers/servers with lots of connections? 3) Two minor suggestions for clarification: From: 4.3. Static Configuration Nodes may establish IPComp Associations using static configuration. To: 4.3. Static Configuration Nodes may establish IPComp Associations using static configuration (manual setup). From: 5. Security Considerations ...... In particular, the original value of the Protocol field in the IP header is not located in its normal positions within the datagram, and any transport header fields within the datagram, such as port numbers, are neither located in their normal positions within the datagram nor presented in their original values after compression.......

In particular, the original value of the Protocol field in the IP header is not located in its normal positions within the datagram, and any transport-layer header fields within the datagram, such as port numbers, are neither located in their normal positions within the datagram nor presented in their original values after compression.......
