“…From NFV perspective, the placement problem refers to the placement of VNF nodes over a NFV-based network infrastructure, which is so-called VNF placement (VNFP) problem. The VNFP problem in the MPC network has recently attracted some attention in the literature with the goal of finding the optimal location for a single type of VNF such as in [162] and [163] or a set of different VNFs such as in [147] and [164]- [167], while guaranteeing different performance constraints ranging from minimizing the network load, resources, and power consumption to ensuring the users' QoE and QoS. Another variant of placement optimization called Virtual Network Embedding (VNE) problem [178], in which the virtual network topologies and resource demands are mostly static [179], has also been considered by Baumgartner et al [168], [169].…”

“…Studies such as [17,96] address the placement problem of SGW and PGW. Taleb et al [17] present different solutions for optimizing user plane response time and SGW relocations by considering user mobility patterns along with delay and relocation constraints.…”
