Abstract
En 中文
To adapt the rapid upgradation of the communication technology (e.g., from 5G to 6G) and reduce the redeployment cost, the Network Functions Virtualization (NFV) is regarded as a key technology to reduce the capital expenditures (CAPEX) and operating expenses (OPEX) by decoupling traditional network functions from proprietary hardware appliances to software appliances. However, with increasing data transmission requirements, the limited traffic capacity is still the bottleneck of NFV network and strongly related to three aspects: 1) NFV network structure construction; 2) resource allocation; 3) routing design for packet navigation. In this brief, we first present a preferential link attachment mechanism to model the growth evolution of the NFV network. Secondly, we propose to efficiently allocate virtual resource for every Virtualized Network Fucntion (VNF). Thirdly, we propose a new routing mechanism to fully make use of the network resource and enhance the traffic capacity. Finally, extensive experiments demonstrate that our integrated solution systematically formulates the traffic dynamics for the future NFV deployment.
