Endpoint Handlespace Redundancy Protocol (ENRP)

Abstract

Status of This Memo This memo defines an Experimental Protocol for the Internet community. It does not specify an Internet standard of any kind. Discussion and suggestions for improvement are requested. Distribution of this memo is unlimited.

An Overview of Reliable Server Pooling Protocols

“…This document provides an overview of the RSerPool protocol suite, specifically the Aggregate Server Access Protocol (ASAP) [RFC5352] and the Endpoint Handlespace Redundancy Protocol (ENRP) [RFC5353]. In addition to the protocol specifications, there is a common parameter format specification [RFC5354] for both protocols, a definition of server selection rules (pool policies) [RFC5356], as well as a security threat analysis [RFC5355].…”

“…Second, the decision as to which server is to be used can be determined dynamically by the server selection mechanism (i.e., a "pool policy" performed by ASAP; see ASAP [RFC5352]). Finally, when failures occur, these are reported to the pool via signaling present in ASAP [RFC5352] and ENRP [RFC5353]; other clients will eventually know (once this failure is confirmed by other elements of the RSerPool architecture) that this server has failed.…”

“…This document does not require additional IANA actions beyond those already identified in the ENRP [RFC5353] and ASAP [RFC5352] protocol specifications.…”

“…They use ENRP [RFC5353] to maintain synchronization of data concerning the pool handle mapping space. For PUs and PEs, the ENRP servers are functionally equal.…”

Threats Introduced by Reliable Server Pooling (RSerPool) and Requirements for Security in Response to Threats

“…This document is related to the RSerPool Aggregate Server Access Protocol (ASAP) [RFC5352] and Endpoint Name Resolution Protocol (ENRP) [RFC5353] documents, which describe, in their Security Consideration sections, the mechanisms for meeting the security requirements in this document. TLS [RFC5246] is the security mechanism for RSerPool that was selected to meet all the requirements described in this document.…”
