Table of Contents

1. Introduction

1.1. Abbreviations

1.2. Reliable Server Pooling

Reliable Server Pooling (RSerPool) has been defined as RFCs in [1], [2], [3], [4], [5], [6], [7], [8]. There is also a detailed introduction provided by [16] as well as lots of further information material on [22]. RSerPool is therefore not introduced in more detail here.

1.3. Scope

The scope of this document is to collect some ideas of what to update/change for a next generation of the RSerPool framework. It is a result of lessons learned with more than one decade of RSerPool deployment (see also [17], [18], [19]) as well as ongoing discussions on applying RSerPool for Virtual Network Function Resource Pooling (VNFPOOL; as introduced in more detail in [15]).

2. What to Change in the Next Generation of RSerPool?

2.1. Security Considerations

Security considerations for RSerPool can be found in [6].

2.2. IANA Considerations

This document introduces no additional considerations for IANA.

3. Reference Implementation

The RSerPool reference implementation RSPLIB, including example applications, can be found at [22]. It supports the functionalities defined by [2], [3], [4], [5] and [6] as well as the options [12], [14] and [13]. An introduction to this implementation is provided in [16].

4. Testbed Platform

NorNet is a large-scale and realistic Internet testbed platform with support for Reliable Server Pooling as well as the underlying transport protocols SCTP and MPTCP. A description of and introduction to NorNet is provided in [19], [20], [21]. Further information can be found on the project website [23].

5. Acknowledgments

The author would like to thank Randall R. Stewart, Michael Tuexen, Ning Zong for their discussions and support.
