Serviços virtualizados de rede podem ser construídos através da combinação de múltiplas VNFs (Virtualized Network Functions) conectadas em uma ordem predefinida, denominada de SFC (Service Function Chain). A IETF define uma arquitetura padronizada para SFCs, baseada em elementos de classificação e de encaminhamento. Considerando que diversos serviços de rede implementam funcionalidades críticas para o funcionamento correto da rede, falhas em qualquer componente da SFC podem comprometer toda a infraestrutura, levando a prejuízos monetários ou até mesmo ao uso não autorizado do sistema. Neste contexto, este trabalho propõe a FIT-SFC (Fault- & Intrusion Tolerant SFC): uma arquitetura para suportar serviços virtuais seguros e altamente disponíveis. Enquanto grande parte dos trabalhos anteriores consideram somente falhas por parada, a FIT-SFC utiliza estratégias de replicação para tolerar falhas bizantinas de qualquer componente da arquitetura SFC, sendo ainda totalmente compatível com a arquitetura de referência da IETF. Um protótipo da arquitetura foi implementado como prova de conceito e resultados experimentais avaliam os custos para tolerar as falhas.

SummaryNetwork function virtualization (NFV) is a name of technology for replacing hardware‐based network functions with software programs. Virtual network function (VNF) is a software program that replaces the hardware‐based network functionality. The replacement of the hardware‐based network functions (middleboxes) with software programs promises the on‐demand provisioning of network functions and reduces capital and operational expenses of the network. Due to this replaced network can adapt to the different network functions. Network service providers deploy various network services with different objectives, such as reducing the network's active servers and traffic latency or network operational expenses. In this article, a VNF placement problem is studied to optimize the total operating costs of the networks. To solve the VNF placement problem, we proposed an integer linear program (ILP) model, which has been implemented using CPLEX. Although an ILP‐based approach gives an optimal solution, it takes a long execution time to find the solution. Due to the long execution time, the ILP‐based approach is not suitable for the real‐time VNF placement problem. To address this challenge, we proposed a heuristic based on dynamic programming that performs better than the existing approaches. The simulation results of the proposed solution using real‐world topologies show that the heuristic approach finds a feasible solution that is only 1 to 1.34 times far from the optimal one. Moreover, experimental results show that the proposed heuristic is 15 to 423 times faster than the ILP.

“…Several approaches have been investigating how to evolve and support the adoption of NFVs. These approaches include the automation of different steps related to the deployment and management of VNFs, such as marketplaces to automate the offering, distribution, and deployment of VNFs [2], orchestration platforms [21], and tools to test their solutions in controlled scenarios [33].…”

Network Functions Virtualization (NFV) has been a key part of evolving communication systems in the last few years. However, the life-cycle management of Virtual Network Functions (VNF) is still a not trivial task. Blockchains (BC), due to their decentralization and immutability characteristics, together with the automation provided by Smart Contracts (SC), can be employed to enable such automated and trustworthy VNF management.Thus, this paper proposes VeNiCE to automate the deployment and life-cycle management of VNFs using events emitted on SCs. VeNiCE provides automation and auditability by relying on a BC to provide a decentralized approach for VNF management, which performs management actions, such as VNF deployment and deletion, and based on events and communicates with an SC to provide immutable logging of the VNF life-cycle. VeNiCE provides (i) a frontend for user interaction, (ii) a backend implementing the communication with the NFV framework, and (iii) an SC that emits events, stores VNF allocations, and authenticates users. A prototype of VeNiCE was developed and deployed in the Ethereum BC using OpenStack Tacker as an NFV platform. Experiments were conducted in a real-world deployment of such a prototype to analyze the economic costs of using SCs and the time required to process requests by each component of VeNiCE and the BC. Those results obtained show VeNiCE's feasibility, highlight its benefits achieved with the automation and provide insights on reducing costs by exploring additional BC platforms and different deployment types, which introduce centralization and management concerns.
