When using the packet-size negotiation of X.25 what is intended to happen? Because X.25 is a DTE-DCE protocol (on all levels), is the packet size negotiation theoreticaly only for the local interface between DTE and DCE, or is the interface at the remote side also involved (that is what pratis is telling me). Furthermore I thought that the network could help in different packet size at the remote and local side (by using buffers and M-bits it can help de DTE's in communicating). So my question is: Is pacjet-size negotiation (the same for window and throughput) an end-to-end facility in theory and in practice. Thanks for your help, All the best, Victor
