The purpose of this BOF is to standardize a reliability protocols that can be used by a general class of applications to: 1) Seamlessly support server pooling 2) Support automatic receiver failover; when the chosen server fails redirect the message to another server 3) Allow implementation of flexible load assignment and balancing policies among servers 4) Allow servers to be added and removed from the pool transparently 5) Support a fully distributed name space for achieving a high degree of fault tolerance As the target of this effort is to support the requirements of a large class of applications, we will begin by collecting requirements from a variety of application areas. Included in this group are telephony call control, location registers and other services. Architectural considerations are important. An architectural framework will clarify building blocks - that is a set of easily separable course grained modular components. To assist in this standardization process, the BOF will begin with work on two documents. The first will describe the requirements for reliable server pooling. The second will be an architecture framework document. These two documents will be initially submitted as BOF drafts and subsequently proposed as Informational RFCs. The WG will carry out protocol standardization by composing two RFCs that specify: - a fault tolerant name translation service - a user interface for name to address translation, load sharing management and fault management. RSpool will consult with other IETF working groups such as Reliable multicast, DNS extensions and Sigtran as appropriate. We will not duplicate any of these efforts.
