“…It is our belief that overall substrate resource use is improved if the incoming media cloud request is mapped to the MEC-DCs simultaneously for both its networking and computing requirements. Our approach, proposed in "Media edge cloud resource allocation approach" section, has two crucial improvements over related works in the literature [11][12][13][14][15][16][17][18][19][20]20]. The first improvement is a resource allocation strategy that uses the physical characteristics of the networking layer to reduce the deployment cost.…”

“…Virtual network embedding in power minimized IP over O-OFDM saves 63% of the optical layer power consumption compared to VNE in IP over WDM while the spectrum minimized virtual network embedding saves 17% of the optical layer power consumption compared to the WDM implementation [6]. The power minimized O-OFDM network selects routes and modulation formats that result in minimum power consumption while the spectrum minimized O-OFDM selects routes that can support the highest modulation format to minimise the used spectrum.…”

“…BVTs can adjust their actual transmission rate in response to the actual traffic demand through expansion or contraction of the optical path by varying the number of subcarriers used or the modulation format of subcarriers. By deploying optical OFDM (O-OFDM) as the underlying technology in the optical layer, replacing WDM, the virtual network embedding problem therefore extends all the way to the selection of the number of subcarriers and modulation format used during the link provisioning phase in the substrate network [5], [6].…”

“…We addressed the link embedding problem as a multilayer problem that includes both the IP layer and the optical layer in an IP over WDM network and considered the granular power consumption of various network devices as well as the power consumption in data centers. In [10], we extended our study to investigate the energy efficiency of VNE in optical OFDM networks. In [11] and [12], we have looked at green IP over WDM networks with data centers where we employ renewable energy sources and consider data center location optimization to minimize energy consumption.…”
