“…Fifth‐generation network infrastructures will become increasingly multitenant, hosting heterogeneous types of tenants with different requirements, with the need of adopting a service model where each tenant is provided with its own virtual infrastructure. In this context, network virtualization becomes crucial and, when combined with IT virtualization, allows service providers to create multiple coexisting isolated end‐to‐end virtual infrastructures for their tenants. SFC defines a specifically ordered list of network services/functions (eg, load balancers, firewalls, etc) based on use scenario requirements and manages traffic redirection functionalities to ensure that the traffic in the infrastructures is flowing through certain services. Security Group Control manages firewall‐filtering functionalities in order to provide control of traffic being produced or consumed in the infrastructure. It includes filtering of traffic based on MAC and IP addresses, port number, packet type, etc.…”

Summary This paper presents the design and prototype implementation of the SELFNET fifth‐generation (5G) mobile edge infrastructure. In line with the current and emerging 5G architectural principles, visions, and standards, the proposed infrastructure is established primarily based on a mobile edge computing paradigm. It leverages cloud computing, software‐defined networking, and network function virtualization as core enabling technologies. Several technical solutions and options have been analyzed. As a result, a novel portable 5G infrastructure testbed has been prototyped to enable the preliminary testing of the integrated key technologies and to provide a realistic execution platform for further investigating and evaluating software‐defined networking– and network function virtualization–based application scenarios in 5G networks.

“…Specifically, as far as a single service node is concerned, if the occupancy ratio of certain resource reaches the threshold, the node cannot run new instances any more. Third, flows should be routed in such a way to follow the sequence specified by SSC while optimizing the latency of security service, since latency is an important factor in measuring network performance [13][14][15]. Hence, an optimal solution of SSC-DP is needed to satisfy service demand of security request while minimizing resource consumption of service nodes and reducing resource fragmentation as well as forwarding flow through the best available path with the minimal security service latency.…”

Security functions are usually deployed on proprietary hardware, which makes the delivery of security service inflexible and of high cost. Emerging technologies such as software-defined networking and network function virtualization go in the direction of executing functions as software components in virtual machines or containers provisioned in standard hardware resources. They enable network to provide customized security service by deploying Security Service Chain (SSC), which refers to steering flow through multiple security functions in a particular order specified by individual user or application. However, SSC Deployment Problem (SSC-DP) needs to be solved. It is a challenging problem for various reasons, such as the heterogeneity of instances in terms of service capacity and resource demand. In this paper, we propose an SSC-based approach to deliver security service to users without worrying about physical locations of security functions. For SSC-DP, we present a three-phase method to solve it while optimizing network and security resource allocation. The presented method allows network to serve a large number of flows and minimizes the latency seen by flows. Comparative experiments on the fat-tree and Waxman topologies show that our method performs better than other heuristics under a wide range of network conditions.

“…1 In addition, it is also very difficult to deploy new services in legacy networks because of the inflexible and ossified network architecture. In order to provide various services for network users, a large number of middleboxes (eg, firewall, intrusion detection, network address translation (NAT), and load balancer) have been developed.…”

The integration of software-defined networking (SDN) and network function virtualization (NFV) enables the flexible deployment of network services and significant reduction in service provisioning cost. In particular, SDN, as a new networking paradigm, supports the flexible provisioning of new network services. Meanwhile, in NFV, the service request from end user can be represented as the service function chain (SFC). However, with the continuously increasing of network users and constant enlargement in network scale, the deployment of network services in the large-scale SDN network, which is composed of multiple SDN domains, becomes more challenging since these SDN domains are managed and maintained by different network operators and service providers. To address the above challenge, in this paper, we study the problem of how to deploy network services across multiple SDN domains optimally. Specifically, we first formulate this problem as an optimization problem by jointly minimizing the total number of SDN domains occupied by SFCs and the corresponding network resource consumption cost. We propose a novel heuristic deployment algorithm to solve this optimization problem. The simulation results demonstrate that the proposed heuristic deployment algorithm is effective and outperforms the comparison algorithms in terms of the total service cost.
