Types ¶
type EndpointSliceGroup ¶
type EndpointSliceGroup struct {
// Label is a unique identifier for an EndpointSliceGroup. This often
// represents a topology label that the group will be consumed from.
Label string
// Composition stores contribution of endpoints in this group from different
// zones
Composition map[string]WeightedEndpoints
// ZoneTrafficWeights this sliceGroup has for requests from different zones
ZoneTrafficWeights map[string]float64
}
EndpointSliceGroup represents all the EndpointSlices under a same label, one group may be made up by many EndpointSlices (when the number of endpoints excceeds the capacity of one EndpointSlice). Since for now there is no need to know how the group is composed, we keep them as a whole
func (EndpointSliceGroup) NumberOfEndpoints ¶
func (e EndpointSliceGroup) NumberOfEndpoints() int
NumberOfEndpoints calculates number of endpoints of a specific EndpointSliceGroup
func (EndpointSliceGroup) NumberOfWeightedEndpoints ¶
func (e EndpointSliceGroup) NumberOfWeightedEndpoints() float64
NumberOfWeightedEndpoints calculates weighted number of endpoints of a specific EndpointSliceGroup
type EndpointsTraffic ¶
type EndpointsTraffic struct {
// EndpointsTrafficLoad for different endpoints belong to a zone in
// different sliceGroups
// key: sliceGroup label endpoints assigned to
EndpointsTrafficLoad map[string]float64
// EndpointsTrafficLoadDeviation for different endpoints belong to a zone
// in different sliceGroups
// key: sliceGroup label endpoints assigned to
EndpointsTrafficLoadDeviation map[string]float64
// MaxDeviationSG (SG:sliceGroup) of endpoints in a zone
MaxDeviationSG string
// MeanDeviation of endpoints in a zone
MeanDeviation float64
}
EndpointsTraffic stores traffic load details of endpoints in a zone
type RegionInfo ¶
type RegionInfo struct {
// TotalNodes of all zones
TotalNodes int
// TotalEndpoints of all zones
TotalEndpoints int
// ZoneDetails by zone
ZoneDetails map[string]Zone
}
RegionInfo wraps information of zones in a region
func CreateRegionInfo ¶
func CreateRegionInfo(zones []Zone) (RegionInfo, error)
CreateRegionInfo creates regionInfo with zone infos
type SimulationResult ¶
type SimulationResult struct {
// Invalid if something ends up with unexpected errors, i.e. some zones have
// no endpoints to send traffic to, illegal routing weights (weights < 0)
// etc.
Invalid bool
// InZoneTraffic is the total ratio of traffic that stays in the same zone
InZoneTraffic float64
// TrafficDistribution groups zoneTraffic by zone name
TrafficDistribution map[string]ZoneTraffic
// MaxDeviation of traffic load of all endpoints
MaxDeviation float64
// MeanDeviation of traffic load of all endpoints
MeanDeviation float64
// DeviationSD represents the standard deviation of the daviation of traffic
// load across all endpoints
DeviationSD float64
}
SimulationResult is to collect metrics of a simulation result
type WeightedEndpoints ¶
type WeightedEndpoints struct {
// Number of endpoints
Number int
// Weight of these endpoints when routing in a slice
Weight float64
}
WeightedEndpoints are used to do routing inside an EndpointSliceGroup
type Zone ¶
type Zone struct {
// Nodes is the numer of nodes of this zone
Nodes int
// Endpoints is the Number of endpoints in this zone
Endpoints int
// Name of this zone
Name string
// EndpointsRatio of this zone compared to all endpoints
EndpointsRatio float64
// NodesRatio of this zone compared to all nodes
NodesRatio float64
}
Zone abstracts the conception of 'zone' in clouds
type ZoneTraffic ¶
type ZoneTraffic struct {
// ZoneName of a specific zone
ZoneName string
// Incoming traffic this zone received
Incoming float64
// Outgoing traffic distribution of this zone
Outgoing map[string]float64
// TrafficLoad: ratio between exact traffic received by the zone and its
// expected receiving traffic
TrafficLoad float64
// ZoneTrafficDetail stores detailed traffic load information for all
// endpoints in the zone
ZoneTrafficDetail EndpointsTraffic
}
ZoneTraffic records the detailed traffic infomation of a zone
