Abstract:
High-Availability (HA) is a very important requirement throughout the
history of carrier network, many technologies have emerged for it.
With the trend of Network Function Virtualization (NFV), network
function are migrated from dedicated hardware to software running
over COTS servers, the same SLA of HA should be provided depending on
network service itself. But some new challenges are brought by NFV,
one example is Virtualized Network Function (VNF) cluster caused by
the HA and performance limitation of individual VNF instance. For
the VNF cluster, some gaps exist between with the available HA
technologies on issues of multi-homing, state synchronization, share-
risk prevention and HA role election, especially in the network which
has a large scale deployment of NFV.
This document firstly identifies the challenges emerged within NFV
deployed networks. Then, available HA technologies are reviewed and
the detailed gap analysis between them with the new challenges is
discussed in depth. At last, the summary of these gaps is presented.
