bibo_abstract:
- 'Network appliances perform different functions on network flows and constitute
an important part of an operator’s network. Normally, a set of chained network
functions process network flows. Following the trend of virtualization of networks,
virtualization of the network functions has also become a topic of interest. We
define a model for formalizing the chaining of network functions using a context-free
language. We process deployment requests and construct virtual network function
graphs that can be mapped to the network. We describe the mapping as a Mixed Integer
Quadratically Constrained Program (MIQCP) for finding the placement of the network
functions and chaining them together considering the limited network resources
and requirements of the functions. We have performed a Pareto set analysis to
investigate the possible trade-offs between different optimization objectives. '
