Overview
Edge clouds are located at close proximity to end users. Typical deployment locations are within the access networks or at the boundary of access networks. In some deployments, they can be within the customer premises (e.g., home; enterprise; factory floor; vehicles including trains, planes, private cars). The core thrusts of edge clouds for applications are low latency, high bandwidth, and trusted computing. Various edge cloud architectures have already emerged from different communities and potentially can be plugged into the ONAP architecture for service orchestration. The group addresses the orchestration requirements of services over various edge clouds within ONAP as they impact data collection, processing, policy management, resource management, control loop models, security, and application & network function deployment/control frameworks.
Scope
This group will address the needs of an edge automation environment to satisfy following
- Providing contextual information to application services after gathering information from 5G network functions.
- Traffic steering to the right edge applications (e.g Programming UE classifier of UPF)
- Scaling needs
- Securing confidential information/keys/secrets and detecting any software tampering.
- Optimal placing of edge applications. For example placing edge applications in close proximity of end users.
- Supporting various application types (VMs and containers)
- Performance determinism and high throughput edge
- Deploying IOT specific infrastructure software in edges.
This group will study the needs of edges, identify ONAP role, identify gaps in ONAP to satisfy above needs and propose solutions to address the gaps.
Few examples: on scaling - OOM based scaling may not be good enough and there may be a need to offload some ONAP functionality to regional level as the target number of edge clouds could be in tens of thousands. Also, to reduce amount of data to central ONAP services for analytics, there is a need for offloading DCAE functions to regional level, which could involve identifying real time data sources, collecting and analyzing the data and disseminating output data to central ONAP function. Controlling fabric (L2/L3 switches in edge-clouds and WAN links) is another function that may require offloading some ONAP SDNC functions to regional sites.
Problem Statement:
Initial Draft: Cagatay/Vimal/Kaniz drafted the following, waiting your input.
To Do:
- Problem Statement - Clarify Where/What is Edge...and, focus of this effort
- See Figure 3 in ATT-Edge_Compute_White_Paper FINAL2.pdf
- Edge = vCPE at customer Premises
- Edge = Cell Tower
- Edge = Small Central Office (eg., CU for vRAN)
- Identify Target Communities
- Requirements for ONAP R2+
