Carrier Grade Virtual Mobile Core Networking

Overall Objective – Research Focus:

Network Function Virtualization (NFV) Management and Orchestration:

• Performance/reliability constraint-based VNF placement
• Service-aware resource cloud assessment and allocation
  • QoS/QoE Prediction based service level management
  • Auto-tuning of VMs running VNF
  • Support of user/NW elasticity in carrier cloud
• Opportunistic improvements to EPS and its nodes for NFV
  • Adaptability of EPC VNF to the dynamic & frequent re-distribution & scaling
  • EPC VNF virtualization patterns
  • Lightweight EPC design
• Service resiliency in carrier cloud

Novel approaches for RAN and CN congestion management in 5G networks

• Restricted access grants
• Selective content drop zones
• Agile wireless connection steering
• NFV application for dynamic service chaining to cope with mobile social traffic
• NFV application for the creation of virtual mobile networks and selectively offloading MTC services there (see next slide)

MTC Service-dedicated Virtual Mobile Networking:

Follow Me Cloud Concept: “Service Mobility”:

Research Focus:

Algorithms and mechanisms for service migration:

•     Migration control (when to migrate what)
•     Resource management (slicing, sliding, clean-up)
•     Fast and secure VM migration
•     Migration transparency to user

Algorithms for efficient user service and content distribution/replication:

•    Where and when to place what

Interworking functions between “service layer” and “mobile network layer”:

•     Mechanisms for cloud-aware gateway selection
•     Service continuity support with no impact on mobile communication standards
