TLDR
This paper aims at structuring this field of knowledge by providing introductions to network slicing and blockchain technologies through a global architecture that aggregates the various proposals into a coherent whole while showing the motivation behind applying Blockchain and smart contracts to network sliced.Abstract:
Network slicing is one of the fundamental tenets of Fifth Generation (5G)/Sixth Generation (6G) networks. Deploying slices requires end-to-end (E2E) control of services and the underlying resources in a network substrate featuring an increasing number of stakeholders. Beyond the technical difficulties this entails, there is a long list of administrative negotiations among parties that do not necessarily trust each other, which often requires costly manual processes, including the legal construction of neutral entities. In this context, Blockchain comes to the rescue by bringing its decentralized yet immutable and auditable lemdger, which has a high potential in the telco arena. In this sense, it may help to automate some of the above costly processes. There have been some proposals in this direction that are applied to various problems among different stakeholders. This paper aims at structuring this field of knowledge by, first, providing introductions to network slicing and blockchain technologies. Then, state-of-the-art is presented through a global architecture that aggregates the various proposals into a coherent whole while showing the motivation behind applying Blockchain and smart contracts to network slicing. And finally, some limitations of current work, future challenges and research directions are also presented.read more

Dynamic QoS Management for a Flexible 5G/6G Network Core: A Step toward a Higher Programmability
TL;DR: This research has developed highly flexible, dynamic queue management software and moved it entirely to the application layer (reducing dependence on the physical network infrastructure), and emulated a testbed environment as realistically as possible to verify the proposed model capabilities.

Blockchain and 6G Networks: A Use Case for Cost-Efficient Inter-Provider Smart Contracts
TL;DR: In this article , a framework for a smart contract-based inter-provider agreement leveraging IOTA Tangle, IPFS, and chainlink is proposed to minimize the overall cost of use-cases of 6G networks.

Demo: Blockchain-based Inter-Provider Agreements for 6G Networks
TL;DR: In this article , the authors present the use of the Ethereum smart contract for a use case where the consumer can buy resources from a provider, and leverage IOTA Tangle to reduce the cost of transactions on the Ethereum blockchain and minimize the latency.

Blockchain-based SLA Management for Inter-Provider Agreements
TL;DR: In this article , a use case of a smart contract-based inter-provider agreement is considered, and novel solutions like IOTA Tangle to perform transactions, IPFS to store the hash of use case data files, and chainlink to access off-chain data feeds for SLA monitoring, reducing costs and increasing transparency.

Blockchain-based 6G Inter-Provider Agreements: Auction vs. Marketplace
TL;DR: In this paper , the authors proposed a solution based on blockchain, considering both approaches (i.e., marketplace and auction). Furthermore, they use IOTA Tangle and IPFS to reduce the transaction and gas costs, which is one of the challenges for Ethereumbased use cases.

The Byzantine Generals Problem
TL;DR: The Albanian Generals Problem as mentioned in this paper is a generalization of Dijkstra's dining philosophers problem, where two generals have to come to a common agreement on whether to attack or retreat, but can communicate only by sending messengers who might never arrive.

In search of an understandable consensus algorithm
Diego Ongaro,John Ousterhout +1 more
TL;DR: Raft is a consensus algorithm for managing a replicated log that separates the key elements of consensus, such as leader election, log replication, and safety, and it enforces a stronger degree of coherency to reduce the number of states that must be considered.
