Market Driven Multidomain Network Service Orchestration in 5G Networks

Abstract

The advent of a new breed of enhanced multimedia services has put network operators into a position where they must support innovative services while ensuring both end-to-end Quality of Service requirements and profitability. Recently, Network Function Virtualization (NFV) has been touted as a cost-effective underlying technology in 5G networks to efficiently provision novel services. These NFV-based services have been increasingly associated with multi-domain networks. However, several orchestration issues, linked to cross-domain interactions and emphasized by the heterogeneity of underlying technologies and administrative authorities, present an important challenge. In this paper, we tackle the cross-domain interaction issue by proposing an intelligent and profitable auction-based approach to allow inter-domains resource allocation.

A Survey on Distributed NFV Multi-Domain Orchestration from an Algorithmic Functional Perspective

“…After reviewing the works, we identify nine requirements for successful distributed MdO algorithms and illustrate them based on two use cases. The first case U1 is a competitive Massively Multiplayer Online Game running with many orchestrators [4]. Many concurrent players meet around a shared virtual environment.…”

“…Cross-domain interaction among multiple providers was studied in [4]. The authors propose an auction-based market where service providers exchange network resources by buyer/seller transactions.…”

NFV and Blockchain Enabled 5G for Ultra-Reliable and Low-Latency Communications in Industry: Architecture and Performance Evaluation

“…6. Two scenarios are investigated with the number of competing traffic to be 2 and 4 respectively (m i = [2,4]). From Fig.…”

“…( 12). The system configurations for each transmission path are set to be µ s =0.128 Mbps, n = [4,8,16,32], ϕ 1 =0.5, ϕ 2 =0.1, λ 1 = 0.4 Mbps and m i = 2. Two transmission paths are considered in this scenario.…”

“…One efficient solution to overcome these limitations is to design the promising 5G networks, which are characterized by ultra-high traffic volume density, ultra-high connection density, and ultra-high mobility [1], [4], by introducing emerging technologies, like Network Functions Virtualization (NFV) [5], [6], [7]. The concept of NFV originated from service providers looking to increase the agility and flexibility of deploying new network services to support ever-increasing customer requirements.…”
