Abstract:
Network functions are traditionally implemented on specialized
hardware rather than on general purpose servers, but there is a clear
trend to implement a number of network functions, such as firewall or
load balancer, as software on virtualized computing platforms. These
virtualized functions are called Virtualized Network Functions
(VNFs). We call a group of such VNFs a VNF set, which can be used to
build network services. The use of VNF set to build network services
introduces additional challenges on reliability, such as additional
points of failure and the need to coordinate various VNFs.
This document introduces a general idea of VNF Pools to support
reliable function provision by the VNF set. We then highlight the
reliability challenges and problems when using the VNF set to build
services. Related IETF works are also briefly described.
