TRUST BASED ROUTING METRIC FOR RPL ROUTING PROTOCOL IN THE INTERNET OF THINGSpijans
While smart factories are becoming widely recognized as a fundamental concept of Industry 4.0, their implementation has posed several challenges insofar that they generate and process vast amounts of security critical and privacy sensitive data, in addition to the fact that they deploy IoT heterogeneous and constrained devices communicating with each other and being accessed ubiquitously through lossy networks. In this scenario, the routing of data is a specific area of concern especially with the inherent constraints and limiting properties of such devices like processing resources, memory capacity and battery life. To suit these constraints and to provide the required connectivity, the IETF has developed several standards, among them the RPL routing protocol for Low powerand Lossy Networks (LLNs). However, and even though RPL provides support for integrity and confidentiality of messages, its security may be compromised by several threats and attacks. We propose in this work TRM-RPL, a Trust based Routing Metric for the RPL protocol in an IIoT based environments. TRM-RPL uses a trust management mechanism to detect malicious behaviors and resist routing attacks while providing QoS guarantees. In addition, our model addresses both node and link trust and follows a multidimensional approach to enable
an accurate trust assessment for IoT entities. TRM-RPL is implemented, successfully tested and compared with the standard RPL protocol where its effectiveniness and resilience to attacks has been proved to be better.

Using IO Visor to Secure Microservices Running on CloudFoundry [OpenStack Sum...IO Visor Project
As microservices grow, traditional firewall rules based on network ACLs are no longer scalable and fall short of providing fine-grained enforcement. Group Based Policy (GBP) is a flexible policy language that allows users to specify policy enforcement based on intent, independent of network infrastructure and IP addressing. Using micro-segmented virtual domains, administrators can define policies at a centralized location and use IO Visor technology for distributed enforcement. This provides infrastructure independent rules, template-based policy definitions, and scale-out policy enforcement for a solution that secures and scales with microservices. This session will be presented by members of the IO Visor community and will cover how IO Visor technology can be used to define and enforce GBP. The discussion will also cover using GBP for cloud foundry application spaces where microservices are deployed and need scalable, efficient security policies.

Fully programmable SmartNICs allow new offloads like OVS, eBPF, P4 or vRouter, and the Linux kernel is changing for supporting them. Having these same offloads when using DPDK is a possibility although the implications are not clear yet. Alejandro Lucero presented Netronome’s perspective for adding such a support to DPDK mainly for OVS and eBPF.
Accelerate Service Function Chaining Vertical Solution with DPDKOPNFV
Service Function Chaining (SFC) is one of top 5 NFV use case. Supporting SFC in provider and enterprise networks requires performance assurance. Specifically, the Classifier and the Service Function Forwarder which are typically implemented in software such as virtual switches need to match line rate requirement. DPDK (Data Plane Development Kit) is an open source project comprising a set of libraries and drivers for fast packet processing. In this presentation, we will discuss our experiences accelerating SFC with DPDK. In addition, Telco and Datacenter carriers demands dynamic SFC that requires new SFC wire protocols (e.g. VxLAN-GPE and NSH) support in both data and control planes. We intend to share our experiences and future works of a high performance, NSH-aware SFC vertical solution with open-source ingredients: Openstack, Opendaylight, OpenvSwitch with DPDK acceleration.

The session provides an update to on the DPACC project within the OPNFV with a brief discussion on APIs and implementation progress. This session will review the API definition progress and follow up with a demo highlighting a common application as the vNF running on top of the DPACC defined layers. The demo will highlight the use of both hardware and software acceleration utilizing the DPACC defined acceleration layers. The demonstrationIt will highlight the progress in optimizing performance and latency characteristics of a platform to realize the vision of NFV while meeting stringent requirements, particularly for certain workloads, required by carriers.
