The purpose of this group is to develop or adopt procedures, mechanisms and protocols to support user roaming among groups of Internet service providers (ISPs). This is different from, but related to, the work of the IP Routing for Wireless/Mobile Hosts Working Group (mobileip) in that the roamops group is not concerned with the movement of hosts or subnets, but of users. Thus far, the group has produced an architectural document describing the basic mechanisms required to support user roaming, a description of several existing roaming implementations and defined a standard username syntax to support roaming. A repository for documentation describing current roaming implementations is also maintained. In the future, the group will address interoperability among ISPs and roaming users by standardizing such items as network usage data exchange (including the content, format and protocols involved), phone book attributes and exchange/update protocols, authentication and authorization mechanisms and exploring in in depth the security issues involved with roaming. This work is expected to consist mainly of new or revised procedures and application-layer protocols, in addition to recommendations for the fulfillment of the Internet roaming requirements. Any and all business issues regarding the operation of an ISP roaming network (such as settlement, business and billing methods) are specifically NOT in the scope of the roamops Working Group and will not be discussed. The group will work closely with other IETF Working Groups (including mobileip, saag and cat) to identify issues to which the roamops group should attend, as well as to assure that their work does not make roaming unnecessarily difficult or impossible. The utmost goal of the group will to make sure, by any means necessary, that it produces documents of high quality that are useful to the IETF community.
