Learning from massive network data to produce cognitive knowledge for efficient resource management in 5G and beyond 5G (B5G) is still challenging. We are delighted to introduce the readers to this special section of the IEEE Transactions on Cognitive Communications and Networking (TCCN), which aims at exploring recent advances and addressing pract...
Article
Information-Centric Networking (ICN) has been proposed as one of the future Internet architectures. It is poised to address the challenges faced by today’s Internet that include, but not limited to, scalability, addressing, security, and privacy. Furthermore, it also aims at meeting the requirements for new emerging Internet applications. To realiz...

One of the key goals of future 5G networks is to incorporate many different services into a single physical network, where each service has its logical network isolated from other networks. Besides, Network Slicing (NS) is considered as the key technology for meeting the service requirements of diverse application domains. Recently, NS faces severa...

5G networks are anticipated to support a plethora of innovative and promising network services. These services have heterogeneous performance requirements (e.g., high-rate traffic, low latency and high reliability). To meet them, 5G networks are entailed to endorse flexibility that can be fulfilled through the deployment of new emerging technologie...

Identity-as-a-Service (IDaaS) is one of the most famous fruitful authentication services for cloud deployment to Software-as-a-Service (SaaS) model. It is a third party approach for identity management including creation, authentication and privacy assurance. In this work, the Virtual Identity (VID), as a new realization for IDaaS terminology which...

The upcoming 5G ecosystem is envisioned to build business-driven Network Slices to accommodate the different needs of divergent service types, applications and services in support of vertical industries. In this paper, we describe the Network Slicing concept, by unveiling a novel Network Slicing architecture for integrated 5G communications. Furthe...
Article
Knowing the variety of services and applications to be supported in the upcoming 5G systems, the current "one size fits all" network architecture is no more efficient. Indeed, each 5G service may have different needs in terms of latency, bandwidth, and reliability, which cannot be sustained by the same physical network infrastructure. In this conte...

We present the design and implementation of a Content-Delivery-Network-as-a-Service (CDNaaS) architecture, which allows a telecom operator to open up its cloud infrastructure for content providers to deploy virtual CDN instances on demand, at regions where the operator has presence. Using northbound REST APIs, content providers can express performa...

... II. RELATED WORK To predict performance of a network for a particular configuration, a model and an optimization algorithm are required. Analytical modeling, including queuing theory [10] and other algorithms applied to 5G and B5G [11], are traditionally used to develop network models. However, in such modeling the assumption of non-realistic and static properties of real-world networks leads to poor predictions. ...
... As described in Table 3, all the links in Figure 5 can meet the delay requirements of mMTC and eMBB. However, some links like (3,2,1,10,9,8) cannot fulfill the delay requirement of URLLC. For URLLC traffic, the paths (3,11,6,7,8) and (3,11,8) can meet the delay requirements of URLLC flows with DSCP 22. mMTC flows denoted by light yellow select the path (3,2,1,10,9,8). ...
... Zhang et al. [7] analyzes the combination of blockchain and SDN to ensure the trust of network platform and effective network management. Huang et al. [8] proposed and implemented a low-latency MEC framework based on SDN, which provided flexible data plane programmability for MEC and mobile core networks while maintaining compatibility with Third-Generation Partnership Project (3GPP). Katov et al. [9] proposed a method for resource consolidation toward minimizing the power consumption in an extensive network, with a substantial resource over-provisioning. ...
... While the core and transport network resources can be more easily dimensioned and isolated for each slice, RAN resource sharing across slices remains a challenge hard to tackle [7]. For illustration, radio access network (RAN) slices might employ different numerologies (i.e, OFDM waveform parameters) to meet the various 5G vertical requirements [8]. In this work, we investigate the multi-tenant RAN slicing problem in 5G networks. ...
... One such service could involve CDN functionality on demand. In particular, we presented the design of an Anything-as-a-Service scheme for 5G networks [41], as well as an architecture for on-demand virtual CDN deployment over a telco cloud [42]. However, in the former case, we did not expand on the very technologies, algorithms and mechanisms for CDNaaS provision, while the latter design was tailored to a single telecom operator and did not consider the particularities of a mobile network; as such, it is not directly applicable to multi-domain 5G settings where services are deployed on the mobile edge cloud and/or to multi-cloud cases. ...
... L'architecture de Network slicing a été définie par 3GPP [60] et par différentes autres entités de recherche ( [59], [62], [63], [64], [65], [66]) pour gérer les slices. Par exemple, la gestion des slices, définie par 3GPP [67], se fait en quatre étapes (phase de préparation, phase d'instanciation, de configuration et d'activation, phase d'exécution et la phase de mise hors service). ...
