Mission & Scope
Tacker is an OpenStack based VNF Manager service and a framework used to deploy and operate Virtual Network Functions (VNFs) on an OpenStack based NFV Platform. It is based on ETSI MANO Architectural Framework and provides full functional stack to Orchestrate VNFs end-to-end.
High Level Functionality
- VNF Catalog
- Basic life-cycle of VNF (define/start/stop/undefine)
- Performance and Health monitoring of deployed VNFs
- Auto Healing VNFs based on Policy
- Facilitate initial configuration of VNF
Relation to Nova, Glance, Heat :
Tacker makes use of Nova and Glance for VM and image management. Tacker makes use of Heat as a subsystem to manage virtual devices.
Use Cases
No. | Name | Description | User | Priority | Target Release | Status |
---|---|---|---|---|---|---|
1 | Define ServiceVM | Ability to define a ServiceVM template using (a) instance image (2) device specification (to run the image) | Operator | High | Kilo | |
2 | ServiceVM CRUD API | API for basic life-cycle management of ServiceVMs (a) acquire a service-vm instance (b) release a service-vm instance | Plugin | High | Kilo | |
3 | ServiceVM Neutron plugging driver | Neutron port attributes to plug in ServiceVM to appropriate networks (a) Tenant L2 network | Plugin | High | Kilo | |
4 | Resource Pools of ServiceVMs | Operator should be able to configure a pool of ServiceVMs to be in standby for immediate allocation (to avoid bootup latency) | Operator | Medium | L | |
5 | Service allocation using partial ServiceVM | Allocate a portion of ServiceVM for specific service. Reason: Overhead cost of spinning another VM instance is high. If a ServiceVM supports multi-tenancy (for eg VRF for network services) a single ServiceVM can be segregated to support multiple tenant services. Note, there should be 100% tenant isolation while providing this scheme | Operator, Plugin | Medium | L | |
6 | Scheduling Scheme for ServiceVM allocation across a pool of VMs. | Ability to schedule ServiceVMs based on different filters (Gnaat integration). For e.g. Tenant-A might have a higher application throughput needs. It would need a "high-end" FW ServiceVM with SR-IOV nics. Tacker scheduler need to get the "hint" from the plugin and allocate "appropriate" FW ServiceVM from the pool. | Operator, Plugin | Low | M | |
7 | Capacity management of ServiceVM | Ability to report and use "remaining-capacity" data within a ServiceVM to host the next service request | Plugin | Low | L | |
8 | Docker Container Hosted Services | Ability to host a ServiceVM in a Docker Container | Operator | Low | M | |
9 | Physical Appliance Hosted Services | Ability to host a Service-Instance in a physical appliance | Operator | Low | M |
