Types

type Agent

type Agent struct {
	*sim.TickingComponent

	ToOut sim.Port

	Buffer []*TrafficMsg
}

Agent is a component that connects the network. It can send and receive msg to/ from the network.

func NewAgent

func NewAgent(name string, engine sim.Engine) *Agent

NewAgent creates a new agent.

func (*Agent) Handle

func (a *Agent) Handle(e sim.Event) error

Handle defines how an agent handles events.

func (*Agent) NotifyRecv

func (a *Agent) NotifyRecv(now sim.VTimeInSec, port sim.Port)

NotifyRecv notifies that a port has received a message.

func (*Agent) Tick

func (a *Agent) Tick(now sim.VTimeInSec) bool

Tick attempts to send a message out.

type GreedyTrafficInjector

type GreedyTrafficInjector struct {
	PacketSize int
	NumPackets int
	// contains filtered or unexported fields
}

GreedyTrafficInjector generate a large number of traffic at the beginning of the simulation.

func NewGreedyTrafficInjector

func NewGreedyTrafficInjector(engine sim.Engine) *GreedyTrafficInjector

NewGreedyTrafficInjector creates a new GreedyTrafficInjector.

func (*GreedyTrafficInjector) InjectTraffic

func (ti *GreedyTrafficInjector) InjectTraffic()

InjectTraffic injects traffic.

func (*GreedyTrafficInjector) RegisterAgent

func (ti *GreedyTrafficInjector) RegisterAgent(a *Agent)

RegisterAgent allows the GreedyTraffiCInjector to inject traffic from the agent.

type StartSendEvent

type StartSendEvent struct {
	*sim.EventBase
	Msg *TrafficMsg
}

StartSendEvent is an event that triggers an agent to send a message.

func NewStartSendEvent

func NewStartSendEvent(
	time sim.VTimeInSec,
	src, dst *Agent,
	byteSize int,
	trafficClass int,
) *StartSendEvent

NewStartSendEvent creates a new StartSendEvent.

type TrafficInjector

type TrafficInjector interface {
	RegisterAgent(a *Agent)
	InjectTraffic()
}

A TrafficInjector can inject traffic to a network.

type TrafficMsg

type TrafficMsg struct {
	sim.MsgMeta
}

TrafficMsg is a type of msg that only used in standalone network test. It has a byte size, but we do not care about the information it carries.

func NewTrafficMsg

func NewTrafficMsg(src, dst sim.Port, byteSize int) *TrafficMsg

NewTrafficMsg creates a new traffic message

func (*TrafficMsg) Meta

func (m *TrafficMsg) Meta() *sim.MsgMeta

Meta returns the meta data of the message.
