i'm trying to do sometype of Frame Relay compression between a Bay router and a CiscoRouter. Nortel states that they do not do FRF.9 which is a standard Frame Relay comp. because they haven't gotten much of a demand for it. Are there any other types of compression algorithms for Frame Relay and any websites that are helpful ? He mentioned Hi/fn compression but i'm not finding much info on this either. Any help is appreciated. Thanks Mufti Nayeem Ahmed Network Systems Engineer Market Data Networks Reuters America Inc.
