“…The work in [3] proposes an orchestrator architecture to handle virtual services across different operators exploiting a multi-domain PCE as orchestrator module for each provider. Finally, a number of studies discussed smart mechanisms to allow authenticated peer PCE to infer critical intra-domain information of adjacent domains through licit PCEP requests exploiting concepts such as signature-based and anomaly-based detection and trust management mechanisms [23], [24].…”

Abstract-Next-generation 5G concepts are driving infrastructure providers to enable novel services for network operators, such as Virtual Network Function (VNF) and Network Function Virtualization (NFV). Inside a single infrastructure provider, several solutions are available to satisfy the 5G requirements using Software Defined Networking (SDN).However, emerging industry verticals require geographicallydistributed services spanning multiple infrastructure providers. In this multi-provider context, additional complexity emerges to guarantee inter-operability. The orchestrator of each multidomain infrastructure (i.e., MDO), is emerging as the key element to offer services to a federation of infrastructure providers. In this scenario, the procedures for establishing inter-provider services are still an open research topic.This work proposes and evaluates two different procedures to enable multi-provider connectivity service exploiting distributed communication among MDOs. The two procedures are evaluated by means of simulations in a federated multi-provider network based on the Elastic Optical Network technology.

“…Therefore, inter-PCE interactions could be extended with 1) malicious PCEP usage discovery techniques [16] and 2) trust-based and incentive-compatible Fig. 6 Multi-operator service chaining and information flow [15] mechanisms to discourage the misuse of path computation services while stimulating effective interactions among PCEs [10,21].…”

The fifth generation of mobile networks (5G) will support new business and service models. A particular model of business and technical interest is multi-operator service orchestration, where service chains are created dynamically with coordination across multiple administrative domains. In such a scenario, resource sharing among operators is expected to be enabled by emerging network softwarization technologies such as Software-Defined Networking (SDN) and Network Functions Virtualization (NFV). On top of the inherent security issues of network softwarization, the complex relationships between operators add a unique dimension to the fundamental requirements for 5G networks. It is a key objective for network operators to identify new threats and security issues before deploying novel methods for service orchestration. This chapter elaborates on new security challenges posed by multi-operator service orchestration as defined by the H2020 5G-PPP 5G Exchange project. We revisit current standards and recommendations from ITU-T and ETSI under the scope of SDN and NFV. In addition, we present a method for threat analysis as well as gaps between requirements and current security schemes and standards, opening new research directions.
