Tacker is an OpenStack-based NFV orchestration framework that deploys and operates virtual network functions (VNFs). The presentation summarized Tacker's contributions in the OpenStack Queens release, including multiple flow classifiers per VNF forwarding graph, symmetric VNFFG, VNFFG updating, and a Zabbix plugin for VNF monitoring. It also previewed upcoming features in OpenStack Rocky such as container-based VNFs using Kubernetes, and hybrid VNF deployment across Kubernetes and OpenStack.

- 1. Tacker Project Update, OpenStack Summit Vancouver May 2018 Yong Sheng Gong - 99Cloud Dharmendra Kushwaha – NEC Cong Phuoc Hoang - IISTRC
- 3. What is Tacker? • Tacker is an OpenStack based NFV Orchestration framework used to deploy and operate Virtual Network Functions (VNFs). • Tacker is compatible with ETSI NFV Architectural Framework and provides full functional stack to manage VNFs and orchestrate end-to-end Network Services on various VIMs.
