Most softwarized telco services are conveniently framed as Service Function\nChains (SFCs). Indeed, being structured as a combination of interconnected\nnodes, service chains may suffer from the single point of failure problem,\nmeaning that an individual node malfunctioning could compromise the whole chain\noperation. To guarantee "highly available" (HA) levels, service providers are\nrequired to introduce redundancy strategies to achieve specific availability\ndemands, where cost constraints have to be taken into account as well. Along\nthese lines we propose HASFC (standing for High Availability SFC), a framework\ndesigned to support, through a dedicated REST interface, the MANO\ninfrastructure in deploying SFCs with an optimal availability-cost trade off.\nOur framework is equipped with: i) an availability model builder aimed to\nconstruct probabilistic models of the SFC nodes in terms of failure and repair\nactions; ii) a chaining and selection module to compose the possible redundant\nSFCs, and extract the best candidates thereof. Beyond providing architectural\ndetails, we demonstrate the functionalities of HASFC through a use case which\nconsiders the IP Multimedia Subsystem, an SFC-like structure adopted to manage\nmultimedia contents within 4G and 5G networks.\n
