Introduction to the proposal
Please read the attached Powerpoint as an easy introduction to the proposal.
Informal Class Diagram
Aggregate Representation Class Attributes
- A few key attributes of each aggregation representation class are displayed here.
- What is not shown are the various capability, capacity and utilization measures (e.g., CPU capabilities, capacity, optional allocation step size, and utilization) that are to be attached the classes. These measures are essential for placement and management purposes in Edge Automation. These will be added once a consensus is reached on the overall class structure.
Physical DC Endpoint Class:
ID | Type | Cardinality | Description |
Common-name | Name class | 1 | Common name fields across all objects |
Longitude-ID | float | 1 | Physical DC Longitude. |
Latitude-ID | float | 1 | Physical DC Latitude. Lat/Lon distance between physical DCs serves as a good estimate for propagation latency. |
Network-Bandwidth-Info | (DC common-name, value) | 1..n | Maximum incoming/outgoing Network Bandwidth from the physical DC to all other interconnected physical DCs. |
Cloud Region Class
Key Attributes
ID | Type | Cardinality | Description |
Common-name | Name class | 1 | Common name fields across all objects |
Physical-DC-Endpoint-Collection-ID | Physical DC Endpoint Class Collection | 1..n | Used for latency and bandwidth accounting across physical DCs in a distributed data center topology |
Resource Cluster Group Class
ID | Type | Cardinality | Description |
Common-name | Name class | 1 | Common name fields across all objects |
Resource-Cluster-Collection-ID | Resource Cluster Class Collection | 1..n | Collection of multiple resource clusters |
Physical-DC-Endpoint-ID | Physical DC Endpoint | 1 | This is primarily useful in a distributed data center topology -- more details in the cloud region section. |
Resource Cluster Class
ID | Type | Cardinality | Description |
Common-name | Name class | 1 | Common name fields across all objects |
<resource>-Collection-list | <resource> Collection | 1..n | e.g., Collection of multiple compute hosts |
Resource Slice Class
ID | Type | Cardinality | Description |
Common-name | Name class | 1 | Common name fields across all objects |
<tenant>-name | Name class | 1 | Reference to the <tenant>/administrative domain to whom the slice is given. |
<allocated resources>-list | <resource-allocation> Collection | 1..n | Resources with allocations |
