“…In [6], two efficient algorithms are introduced for orchestrating VNF SCs in inter-DC EONs in order to enhance the profit of internet service providers by maximizing the acceptance of user requests. [18] presents a multi-objective optimization model and a few accompanying algorithms for RA in EONs.…”

“…Optical networks, as the main TN solution for connecting DCs, have been expanded to serve inter-and intra-DC connection requests with heavy and bursty traffic streams. Elastic optical network (EON) is a lucrative implementation of optical TNs which enables power-efficient usage of network resources [6]. Flexible and online reconfiguration has made EONs an appropriate platform for inter-connection of VNFs in a service chain (SC) processed distributively on several disperse DCs [6], [7].…”

“…Further, confined processing facilitates handling of interconnected VNF SCs with possible feedback dependencies. In this letter, we assume that each VNF SC is entirely processed within a nominated DC, similar to [6], [20], and use the Lyapunov tool to guarantee the stability of the involved inter-DC network. Such an assumption can even support distributed processing of a VNF SC since each SC can be decomposed into a sequence of VNFs, each processed independently in a nominated DC.…”

Network virtualization, as a key driver for revenue enhancement, is under deep exploration by the communication society. Elastic optical network is a growing inter-data center communication solution whose flexible nature facilitates commercial implementation of virtualization concepts. Flexibility and virtuality are two main pillars of efficient networking which meet in a virtualized inter-data center elastic optical network and their interwoven management can significantly reduce the power consumption of data center networks, as a significant energy-consuming contributor. An efficient resource allocation is required to harvest the expected gain of a virtualized network. We propose a power-efficient joint dynamic resource allocation scheme, which optimally allocates computation and communication resources in an inter-data center elastic optical network. The scheme incorporates the benefits of conventional offline and online resource allocation schemes and reduces the power consumption by 19% compared to its traditional counterparts while keeping the delay and service outage below their desired thresholds. The proposed scheme not only supports traffic streams with distinguished service requirements but also exploits the involved service differentiation to further improve power efficiency. Strikingly, in a typical scenario where delaysensitive and delay-tolerant services co-exist, the reduction in power consumption can be enhanced up to 50%. The efficiency is further improved for a higher number of delay-tolerant services with more relaxed delay requirement. The proposed scheme provides an intelligent compromise between service outage and service requirements under tough networking conditions such that the service requirements of the delaysensitive services are maintained for the least number of dropped bits in the delay-tolerant services.

“…The number of USRs varies from 100 to 300. From Figure 3A, we can see that Algorithm 4 perform better than OLPM_Ndelay 26 and ONSO_PKP 27 in small‐scale network topology because Algorithm 4 can avoid hot nodes in deployment stage and choose nodes with low cost. For example, when USR number is 200, the total revenue of OLPM_NDelay, ONSO_PKP and Algorithm 4 are 5764, 6181, and 6818.…”

Network function virtualization (NFV) is an appealing solution that transforms complex network functions from dedicated hardware to software instances running in a virtualized environment. However, some new challenges will arise when deploying virtual network functions to meet the needs of NFV and edge‐computing (EC) enabled 5G networks. In this paper, we focus on the service function chain (SFC) orchestration problem for EC‐enabled networks to maximize the profit of network service providers. First, the mathematical model of SFC orchestration in NFV and EC‐enabled networks is defined. Then, a two‐stage heuristic algorithm is proposed to optimize the total revenue. Finally, the performance of the method is evaluated by simulation experiments and the results show its effectiveness.
