Kubernetes Topology Simulator

This is not an officially supported Google product.

This will be a key part in the planning and design of topology aware routing for Kubernetes. This specific project will include:

• Building a tool that can be used to test the effectiveness of different topology aware routing algorithms.
• Tweaking algorithms that have already been proposed or propose new ones.
• Writing a report that summarizes the different approaches that can be used for topology aware routing along with a recommendation.

Usage

go run main.go -input=inputFile -output=outputFile -alg=algorithm

example of intput file (csv): each zone with number of nodes first, number of endpoints next

input name, zone1, zone2, zone3  
perfect input, 10 10, 10 10, 20 20

Interfaces

1. Implement algorithms comply with the RoutingAlgorithm interface.

type RoutingAlgorithm struct {
    // CreateSliceGroups translates regionInfo into EndpointSliceGroups
    CreateSliceGroups(regionInfo) (map[string]EndpointSliceGroup, error)
}

2. Add an entry of the algorithm to NewAlgorithm(name string) RoutingAlgorithm introduced in algorithms.go
