Rounding off proof of concept phase, with documented plans - The general model is to connect to services via network, devices, ... - Addresses and Dynamic Service Negotiation have been documented - Default HDLC info fields can go to 256 bytes (negotiate more if needed) - The FCS algorithm will be CRC-16/6sub8, HD(6) up to 8 and HD(4) up to 994 - Documented framework for MRU, MTU, network packet fragmentation, windowing - Services that cannot use fragmentation may fall back on streaming data - Services that cannot use windowing may send REJ instead of SREJ for order - Looked into a large number of services that could make sense
