1. A method for providing cloud embedding using Network followed by Compute Load Balancing (NCLB), comprising:
mapping one or more virtual links over one or more physical links while balancing network resources, and mapping one or more virtual nodes over one or more physical nodes while balancing different types of computational resources; and mapping virtual links (VLs) over a physical links of a sub-network while performing load balancing over network resources, wherein for each VL (i, j), estimating a required amount of spectral resources fij, defined as the product of the shortest distance in terms of hops dij between physical nodes (PNs) over which i and j Virtual Nodes (VNs) are mapped, and a minimum required spectrum Aij, determined from a spectral efficient modulation format to reach at least hij distance, where hij is a physical distance between VNs i and j, and arranging the VLs in a descending order of an estimated required spectrum. |
