Multiple 5G slices concurrently operated on the same infrastructure – with different distribution of control and user plane
2. Dedicated Functions at Cloud Edge Requires security, latency and reliability. (distributed control and user plane)
1. Centralized + Distributed Fully fledged functions distributed across network.
Ref: NGMN 5G White Paper
3. Basic centralized CP, distributed UP Basic control plane and user plane capabilities, no mobility. (central control and distributed user plane)

Personalized applications in cloudlet require low latency (<10 ms), high reliability, mobility support:
- Cognitive assistance (e.g., wearable cognitive devices for healthcare, Google glass, Olympus mobile eye trek) Ref: The case for VM-based Cloudlets in Mobile Computing, IEEE Pervasive Computing.
- V2V (Vehicle-to-vehicle) and V2I (Vehicle-to-infrastructure)

[Ref: 4G Americas Recommendations on 5G Requirements and Solutions]
Flexible mobility means that there may be a range of options based on device type, application, application context or statically configured. Flexible mobility consists of managing mobility and tracking/reachability to save power. Examples with Idle mode mobility on a per-device basis, and active mode mobility on a per-application basis is shown below:

Signaling, data traffic
Signaling and data traffic is growing exponentially. Variety of applications including those with low delay bound, high bandwidth in future. In the future, OTT players will form symbiotic relationship with carriers via dynamic SLA offerings
Future core Network should design for massive signaling, low latency and data demand.

SWITCH SWITCH
Data synchronization in Mobile Core:
– Subscriber data: (read heavy) relatively infrequent updates. Use mobile core signaling to resolve stale/out-of-sync data
– MM/SM context data: (write heavy) frequent updates and routing depends on it. May require locking for maintaining consistency.
– Accounting /charging data: (write heavy) high volume of data. Out-of-sync data can resolved by application (without locking).
Why do we need a distributed data layer ?
– Distributed data service layer that can be evolved, scaled and deployed independently of control.
– Decoupled operation: need to operate in the presence of intermittent wide area network/server failures.
– Latency of accessing remote database is avoided.
– Capability to expose network services

Realize “gateway” functionality with distributed resources: - Multiple controllers in peered and/or hierarchical mode - Forwarding elements that host stateful functions - Service chaining and in-switch autonomous functions - Core forwarding plane fns buffering, paging, mobility management, metering, charging. - Dynamic local measurement services, state monitoring and data aggregation Support for computing services at the Edge (e.g., MEC): - Containerization, pooling of edge cloud resources - Dynamic provisioning across core and edge cloud resources
- Few networking abstractions - limited to “ports”. - limited support for geographic distribution of net
functions - sub-optimal routing path for network flows - low throughput and high latency.
