As many instances of following µ-services (µ-VNF is a µ-service implementing a fine-granule networking function) as needed can be deployed or undeployed (for example, specifying number of replicas).
- Topology Processor (TopoProcessor) µ-VNF: computes various forms of network topology (graph): Min Weight, Shortest Path/Spanning Tree with ECMP (Equal Cost Multi-Path), Next-hop topology for destinations/prefixes/hosts, mapping of the latter to kernel forwarding table and generation of graph visualization. All these functions can be further separated into µ-services. Note that topology/graph computation is general purpose and can be used for other applications.
- Forwarder µ-VNF: forwards packets in overlay datapath. A Forwarder Container functions as a very light-weight packet forwarder (based on Linux kernel forwarding).
- A user/admin of the system specifies overlay network neighbor information for each Forwarder µ-VNF.
- ServiceMapper µ-service.
- Application or server µ-service (App in short).
- Each App is attached to one or more Forwarders automatically or via configured policy and added to the µ-service topology.
Following Global weighted µ-service topology (overlay network topology) is constructed by the TopoProcessor based on pieces of overly neighbor information sent by each Forwarder. The graph visualizations are generated by Visualization µ-services in multiple formats . A Client (browser or other client) makes requests to a µ-service implementing REST APIs, which then makes Go RPC calls to a visualization µ-service that generates topology in visualization formats (DOT/PNG or JS).
Minimum Weighted Topology for Forwarder-2: Node_Weight is the min weight (distance) to reach a node from Forwarder-2
One or more instances (or replicas) of Control Micro-VNF (TopoProcessor) computes the Topology
Shortest Path or Minimum Spanning Tree with ECMP (Equal-cost Multi-Path) for Forwarder-2 computed from avove Min Weight Topology
One or more instances (or replicas) of Control Micro-VNF (TopoProcessor) computes the Topology
Forwarding table computed from above Minimum Spanning Tree with ECMP
This computation can be done via separate Micro-services for each type of Target (Linux, various Hardware)
Each Forwarder is a light-weight Micro-VNF executing mainly forwarding
Table can be mapped to Hardware Forwarding Tables and controlled via the Forwarder Micro-VNF
Above Topology scaled up to 8 (from 6) Forwarders, then to 10 forwarder (via Kubernetes), then to 15 app
Similarly can be scaled down
As Forwarder Micro-VNFs and App Micro-services are scaled up/down, topologies and the forwarding tables are updated automatically
