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), which can be used to build network services. The use of VNFs
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 Pool to support
reliable function provision by the VNFs. We then highlight the
reliability challenges and issues when using the VNFs to build
services. Related IETF works are also briefly described.
