I think I need to understand this vein of research better…

modern services operate under unprecedented multiplicity (in service replicas, host interfaces, and network paths) and dynamism (due to replica failure and recovery, service migration, and client mobility).

Yet, multiplicity and dynamism match poorly with today’s host-centricTCP/IP-stack that binds connections to fixed attachment points with topology-dependent addresses and conflates service, flow, and network identifiers. This forces online services to rely on clumsy and restrictive techniques that manipulate the network layer and constrain how services are composed, managed, and controlled.
