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?
o ENRP servers denote the management systems in the context of
RSerPool. The term "server" is misleading, since ENRP servers are
actually ENRP peers. Literature on RSerPool -- for example [16]
-- therefore uses the more accurate term "Pool Registrar" (PR). A
future revision of RSerPool should also use this term. (The
RSerPool documents did not use "registrar" to avoid confusion with
SIP registrars.)
