Class WUserService

java.lang.Object

com.net2plan.research.niw.networkModel.WUserService

public class WUserService
extends Object

This class represents information of a user service that can be defined in the network, and used to create service chain requests. Users services are bidirectional. Upstream traffic originates in the user, and ends in the network, and downstream traffic ends in the user, and is originated in the network. the characteristics of upstream and downstream traffic can be defined differently. The information comprised is:

• Upstream: The sequence of types of VNF that the upstream traffic should traverse
• Downstream: The sequence of types of VNF that the downstream traffic should traverse
• Upstream: The expansion factor when traversing each upstream VNF: the ratio between the traffic injected by the user in the origin node, and the traffic at the OUTPUT of the VNF.
• Downstream: The expansion factor when traversing each downstream VNF: the ratio between the traffic injected by the origin network node, and the traffic at the OUTPUT of the VNF.
• Upstream: The maximum acceptable latency from the origin node of the upstream flow, to the input of each VNF, and the maximum latency from the origin node of the flow to the end node of the flow
• Downstream: The maximum acceptable latency from the origin node of the downstream flow, to the input of each VNF, and the maximum latency from the origin node of the downstream flow to the end node of the downstream flow
• Downstream: The expansion factor for the initial downstream traffic. This is, the amount of traffic requested to come in downstream direction, for each unit requested in upstream direction
• An indication if the user service should end in a core node. If true, the end nodes of the upstream and the origin nodes of the downstream are constrained to be nodes connected to the core. If not, end nodes of upstream or origin nodes of downstream can be any node in the network.
• Arbitrary: Users services can be attached an arbitrary user-defined string

Method Detail

getArbitraryParamString

public String getArbitraryParamString()

Returns the arbitrary user-defined parameters string

Returns:

see above

getInjectionDownstreamExpansionFactorRespecToBaseTrafficUpstream

public double getInjectionDownstreamExpansionFactorRespecToBaseTrafficUpstream()

Returns the expansion factor for the initial downstream traffic. This is, the amount of traffic requested to come in downstream direction, for each unit requested in upstream direction

Returns:

see above

getListMaxLatencyFromInitialToVnfStart_ms_downstream

public List<Double> getListMaxLatencyFromInitialToVnfStart_ms_downstream()

Gets the list of maximum acceptable latency limits in ms, for the downtream traffic. This is a list with as many elements as the number of VNFs to traverse by the stream plus one. First elements correspond to the maximum latency from the stream origin node to the i-th VNF input. The last element of the list is the maximum traffic from the stream origin node to the stream destination node.

Returns:

see above

getListMaxLatencyFromInitialToVnfStart_ms_upstream

public List<Double> getListMaxLatencyFromInitialToVnfStart_ms_upstream()

Gets the list of maximum acceptable latency limits in ms, for the upstream traffic. This is a list with as many elements as the number of VNFs to traverse by the stream plus one. First elements correspond to the maximum latency from the stream origin node to the i-th VNF input. The last element of the list is the maximum traffic from the stream origin node to the stream destination node.

Returns:

see above

getListVnfTypesToTraverseDownstream

public List<String> getListVnfTypesToTraverseDownstream()

Gets the list of VNF types to traverse by the downstream traffic

Returns:

see above

getListVnfTypesToTraverseUpstream

public List<String> getListVnfTypesToTraverseUpstream()

Gets the list of VNF types to traverse by the upstream traffic

see above

getSequenceTrafficExpansionFactorsRespectToBaseTrafficDownstream

public List<Double> getSequenceTrafficExpansionFactorsRespectToBaseTrafficDownstream()

Gets the traffic expansion factors of the downstream traffic. This is a list with as many elements as the number of VNFs to traverse, with the ratio between the output traffic of each VNF, respect to the input traffic at the stream ORIGIN node.
