All Implemented Interfaces:

Comparable<WAbstractNetworkElement>

public class WServiceChain
extends WAbstractNetworkElement

Instances of this class are service chains, realizing service chain requests. A service chain should start in one of the origin nodes of the service chain, and end in one of the destination nodes of the service chain. The injection traffic of the service chain is the traffic produced by its origin node. Note that when the service chain traffic traverses a VNF, its volume will increase or decrease according to the expansion factor defined for that VNF.

Method Summary

Modifier and Type	Method and Description
WNode	getA() The service chain origin node
WNode	getB() The service chain destination node
double	getInitiallyInjectedTrafficGbps() Returns the traffic injected by the service chain origin node in Gbps
Route	getNe() Returns the underlying Net2Plan object.
List<? extends WAbstractNetworkElement>	getSequenceOfLinksAndVnfs() Returns the sequence of traversed IP links and VNF instances traversed
List<WIpLink>	getSequenceOfTraversedIpLinks() Returns the sequence of traversed IP links, filtering out any VNF instance traversed
List<WVnfInstance>	getSequenceOfTraversedVnfInstances() Returns the sequence of traversed VNF instances, filtering out any IP link traversed
WServiceChainRequest	getServiceChainRequest() Returns the service chain request that this service chain is realizing
void	remove() Removes this service chain, realeasing the resources
void	setInitiallyInjectedTrafficGbps(double injectedTrafficGbps) Sets the traffic injected by the service chain origin node in Gbps
void	setPath(List<? extends WAbstractNetworkElement> seqIpLinksAndVnfInstances) Reconfigures the path of the service chain: the sequence of IP links and VNF instances to traverse
void	setPathAndInitiallyInjectedTraffic(Optional<Double> optInjectedTrafficGbps, Optional<List<? extends WAbstractNetworkElement>> optSeqIpLinksAndVnfInstances) Reconfigures in one shot: (i) the injected traffic by the origin node of the service chain, and (ii) the path of the chain: the sequence of traversed IP links and VNF instances
