Dedicated and shared solutions for reliable function splitting in 5G X-haul

Differentiated Protection in 5G Vehicular Networks

“…Constraint (12) finds the primary (i) and backup (j) nodes performing the different VNFs for each source. Constraint (13) ensures that the capacity reserved for the backup node j is greater than or equal to the capacity required to perform primary functions at node i, to ensure reliability against single primary hotel failure. Constraint (14) finds the primary link (i, j) and the backup link (k, m) carrying traffic of each transport for each source.…”

“…The application of these paradigms is called network slicing, which allows the coexistence of multiple classes of service with different KPIs within the same physical network. Protection schemes need to be deployed in support of different slices on the same transport infrastructure and related resources need to be minimized accordingly, to possibly limit cost and energy consumption [13]. This paper refers to the optical transport network enabling the C-RAN (Cloud-Radio Access Network) solution and proposes an optimization model in the presence of different classes of service (URLLC and eMBB classes), implemented as independent service slices [5].…”
