HI folks, I was wandering if anyone out there have had experience with Serial Link Hardware/Software compression. I have the following scenerio. 1) I have a serial T1 link bewtween two sites, the corrently router hardware use is Site1=4000 series and Seite2=7000 series. Both configure to use HDLC encapsulation. Now, we run a nightly backup through this serial line that takes approximately 8 hours, data comming through is not compressed at all. I was reading the pros and cons of enabling compression either software or hardware on these routers and I am about to test enabling compression at both routers serial interfaces to do software compression "stac", to see if the backup time frame would take less than 8 hours. None of the routers have CSA adapters, so the compression will have to be software/CPU based. Anyone have had experience with this ?
