“…Great efforts have been put into investigating how to efficiently compose and embed an SFC over a shared PN [6], [8], [10], [21]. The work of [10] defined the concept of hybrid SFC (h-SFC), whereas some SF nodes are required to process bidirectional traffic while others only handle unidirectional traffic, and proposed efficient approximate algorithms to solve the h-SFC composing and embedding problem. Furthermore, the authors of [6] comprehensively studied how to optimize the latency of hybrid SFC composing and embedding process, and proposed the first 2-approximation algorithm by utilizing the feature of Eulerian circuit.…”

“…The embedding cost of an SF in version low (L), middle (M ), and high (H ) is randomly set in the range of [12,16], [15,18], and [18,21], respectively; the security of an SF in version L, M , and H is [5,7], [7,9], and [9,11], respectively 1 [41]. The link cost is randomly set in the [1,10] range. Each NSR demands a security requirement within the range of [10,30] units and a bandwidth resource within the range of [1,3].…”

“…To accommodate an NFV-based network service, the service provider (SP) concatenates the required SFs into a chain structure called service function chain (SFC) and deploys it onto a shared physical network (PN) [7], [8]. The process of composing and embedding an SFC over a shared PN is SF chaining and embedding (SFCE) [9], [10]. After the SFCE process, the SF is initialized as an SF instance (SFI) and hosted by a physical node (e.g., server), and the SFC is hosted by a physical path called service function path (SFP).…”

In the 5G and beyond 5G networks, achieving security-aware data transmission needs to convert clients' requests into a service function chain (SFC), each service function (SF) providing a certain security guarantee. With diverse configuration techniques, an SF may own multiple versions, each version providing various security guarantees with diverse costs. In addition, as the recent software failures have caused severe financial loss, great attentions from both academia and industry have been put onto the SFC reliability. In the literature, existing works have solely investigated the following two fields: (i) how to deploy a security-aware SFC, and (ii) how to protect a traditional SFC. Simply applying these techniques to dealing with the problem of security-aware SFC protection might not be efficient as the backup and primary SFCs may not be identical for security-aware SFCs. Therefore, how to jointly take these fields into account is challenging and remains open. To tackle the above problem, this paper studies how to construct and embed a security-aware SFC with asymmetric dedicated protection. We mathematically define this problem and name it security-aware service function chaining, embedding, and protection with multi-versioned SFs (SFCEP-MF) with the objective of cost optimization. Next, to optimize the SFCEP-MF problem, we construct an efficient algorithm, called augmenting-path with primary-first disjoint SFP identifier (APPF-DSI). Extensive simulation results show that the APPF-DSI algorithm outperforms the benchmark approaches that are directly extended from the state-of-the-art.INDEX TERMS Network function virtualization, service function with multi-versions, service function chaining and embedding, security, reliability I.

Network function virtualization (NFV) in 6G can use standard virtualization techniques to enable network functions via software. Resource scheduling is one of the key research areas of NFV in 6G and is mainly used to deploy service function chains (SFCs) in substrate networks. However, determining how to utilize network resources efficiently has always been a difficult problem in SFC deployment. This paper focuses on how to efficiently provision online SFC requests in NFV with 6G. We first establish a mathematical model for the problem of online SFC provisioning. Then, we propose an efficient online service function chain deployment (OSFCD) algorithm that selects the path to deploy that is close to the SFC length. Finally, we compare our proposed algorithm with three other existing algorithms by simulation experiments. The experimental results show that the OSFCD algorithm optimizes multiple performance indicators of online SFC deployment.
