“…The service chaining across datacenter is still in its early stage. However, Gharbaoui et al,in [35] shows experimental validation of an orchestration system for geographically distributed Edge/NFV clouds, supporting end-to-end latency-aware and reliable network service chaining. To do the service changing across datacenters, they set up their experiment on top of the Fed4FIRE+ experimentation platform with three datacenters.…”

Telecommunication carriers of 5G-MEC are re-architecting their central offices and mobile base stations as datacenters with network function virtualization (NFV) technology. These datacenters (DCs) are known as edge datacenters that help network operators speed deployment and reduce costs. Previously, the use of NFV was limited to within a datacenter (DC) known as intra-DC. Recently, many studies have been conducted into the use of NFV across DCs, i.e., inter-DC. However, these NFV inter-DC architectures have limited communication between DCs with either horizontal or vertical connectivity. In this paper, we propose a generic architecture of such edge NFV datacenters with both horizontal and vertical connectivity, and demonstrate the consequences of both vertical and horizontal connectivity between DCs in terms of communication and computing costs. We formulate a cost optimization problem with latency and capacity as constraints by estimating the traffic dispatch rate between DCs. We propose a vertical-horizontal communication (VHC) heuristic solution to the NP-hard problem. Compared to horizontal connectivity, our results show that vertical connectivity helps to reduce computing costs by 10-30%. However, both vertical and horizontal communications together can help to reduce such costs by 20-30% compared to only vertical communication.

“…SDN refers to a network virtualization approach to optimize network resources and quickly adapt the network to changing business requirements, applications and traffic. SDN is implemented by separating the network control flane from the data flane and creating a software programmable infrastructure that is distinct from the physical equipment [10][11][12][13].…”

Background/Objectives: In this paper, we propose a Deep Learning Mechanism (DLMBN) mechanism (Deep Learning Mechanism on Blockchain) that optimizes the load balance that can occur in the network by deep learning some important information related to the load balance after connecting the information of multiple distributed controllers into the blockchain. Methods/Statistical analysis: The proposed mechanism binds and manages the load of each controller distributed over the network with a blockchain, thus reducing load time while dynamically balancing the load balance. In particular, deep learning technology was used to ensure that each controller classified as a group would not be biased to one side and would maintain a balanced load balance across the entire network. Findings: As a result of the experiment, the proposed mechanism improved the load balance retention time by 14.6% on average compared to the mechanism previously studied, and the efficiency of SDNs processed in multiple groups by 17.3% on average. In addition, the overhead of SDNs for each group was lowered by 7.9%. Improvements/Applications: Based on the results of this study, future studies plan to apply the results to the actual network and test whether the performance analysis results are applicable to heterogeneous networks consisting of heterogeneous devices.

“…Recently, several works have addressed the problem of flexibly management of specific service/application traffic, by proposing SFC solutions for flow classification, policy management and traffic steering [8], [11], [14]. Such solutions typically rely of network programming capabilities in the network infrastructure (i.e.…”

“…• an SFC application (SFCLola) managing chain creation and deletion requests. The chain setup leverages an optimization algorithm that selects VNF instances available from different DCs (data centers) to minimize an endto-end latency estimated considering both processing and network latency and sends appropriate chaining instructions to forwarding devices SFCLola can interact with SFC API offered by Virtual Infrastructure Managers (VIM), such as OpenStack SFC API or custom intentbased API (as documented in our previous work [11]).…”

The adoption of Network Function Virtualization and Software Defined Networking technologies allow network infrastructure operator flexibly orchestrating resources to provide tenants with their own virtual network. However, access to computing and network resource management APIs is typically allowed only within the infrastructure domain and rarely disclosed to tenants for security and performance reasons. This may severely limit tenants capability in coping with demands of application-tailored network services, including Service Function Chaining (SFC). While the literature extensively addressed the challenges of SFC in the infrastructure domain, tenant-side SFC management is quite unexplored yet, although discussed also by a standardization group. This work proposes an SFC platform (called SFCLola) providing tenants with a latencyaware SFC management while minimizing support required from infrastructure operators. The platform encompasses two main levels: an end-to-end chain management level featuring a VNF selection algorithm and a forwarding mechanism that can be programmed and enforced within the tenant network of VMs without requiring access to the switches at the network infrastructure data plane. SFCLola has been implemented as software prototype and experimentally evaluated on a multi-DC infrastructure provided by the 5GINFIRE project.
