hi, Maybe this is out-of-topic ,but I can't find any place where could find answer for this question. If this is intrusive, just ingore it please. my question is : how does ISP do with DSL dial-up sessions which pass the accouting period time. E.g. If a customer subscribe DSL service at 15USD/month for 150hours. If the subscriber used 145hours by 30th May. He get online at 21:00 on 31th, and get offline at 5:00 on June 2th. The radius server could only export the customer's session when he get offline. So, problem comes to accouting system which was designed to calculate customer usage on first day of each month. The cut-off line of each month usage is set to 00:00 on first day of each month. Someone says , ISP should force those session closed at 00:00 on first day of each month, because they must ensure dial-up session of last month sould not be accouted in next month. Is this true ? thanks in advance. Joe __________________________________ Yahoo! Movies - Search movie info and celeb profiles and photos. http://sg.movies.yahoo.com/
