I don't know what the future role of Chuck Cranor's ATM software ought to be in FreeBSD, but we would like to continue to make our HARP software (http://www.msci.magic.net/harp) more useful to researchers, (to the extent that funding is available, of course). Thank you everyone for your thoughts on features that might be added to HARP. I have a few questions about possible QoS enhancements for HARP. o Would support for ALTQ in HARP meet all of the identified needs for QoS support over ATM? If not, what else should we consider? o Is there need for RSVP over ATM support, as described in RFCs 2379, 2380, 2381 and 2382? o Is there a need for a user-level, native ATM API that allows QoS parameters to be set? (HARP 3, the version in FreeBSD 3.0, supports the XNS Issue 5 ATM Transport Protocol Information for Sockets interface, but the QoS calls don't do anything. Note that this API is a non-IP API; that is, it allows applications to communicate with HARP directly, rather than through the operating system's IP stack.) - Is there need for a user-level, native ATM API that can set rate shaping parameters for data transmitted out through an ATM interface? - Is there need for a user-level, native ATM API that can set QoS parameters for outgoing SVCs? o Is there need to be able to set administratively (i.e., hand configure) rate shaping parameters for data transmitted through the operating system's IP stack out through an ATM interface? o Is there need to be able to set administratively (i.e., hand configure) QoS parameters for outgoing SVCs that are used by the operating system's IP stack? o Is there need to be able to set dynamically (e.g., via RSVP or some similar mechanism) rate shaping parameters for data transmitted through the operating system's IP stack out through an ATM interface? o Is there need to be able to set dynamically (e.g., via RSVP or some similar mechanism) QoS parameters for outgoing SVCs that will carry IP traffic that is transmitted through the operating system's IP stack out through an ATM interface? o Is anything [known at this time to be] required for IPv6 QoS support beyond ALTQ? o What other QoS facilities should we consider for HARP?
