Hi all.   I am Dan Ellis, CTO of PenTeleData.  We are a regional ISP/communications company owned by 7 cable and telephone companies, responsible for 150k+ broadband subscribers and associated IP infrastructures.  Like many MSO's, we are looking at rolling out a large (300-500+ AP) distributed public hotspot infrastructure and have seen the following issues with both commercial and open source solutions:     - Lack of subscriber accountability (NAT translations). - Inability to see per subscriber "ip accounting/netflow" statistics. - Lack of strong MAC and IP security (easily hijackable) - Inability to control subscriber speeds. - Poor OS implementations (no ssh, non robust upgrades) - Limited or no radius accounting records. - Limited subscriber time/max-transfer control. - Inability to perform internal or external IDS (quarantining). - Limited best practices guides dealing with the above items. - Numerous issues with operator deployment methods.     At the BoF, we hope to compile a list of requirements for vendors in order to get a better set of gear we can build a manageable hotspot infrastructure from.  We'll present our requirements along with any other sets people have, then throw the floor open for discussion.  I will attempt to steer vendors towards these requirements, work on a best practices guide, and then present my results to the Nanog community.     Tim Pozar, Avi Freedman and I will gather for this informal BoF in the Regency Foyer at 12:15pm on Monday, 10/18/04.  If the crowd is of an appropriate size, we'll then move to a local eatery.     Hope to see you there, --Dan       -- Daniel Ellis, CTO, PenTeleData (610)826-9293
