Method Detail

processAceByProcessor

public List<FlowDetails> processAceByProcessor(String nodeName,
                                               ServiceFunctionForwarder theSff,

                                               Optional<RspName> rspName)

Install an ACE entry, belonging to the given ACL, on the SFF identified through the specified nodeName. This method is called on result of classifier addition / removal.

Specified by:

processAceByProcessor in interface ClassifierProcessorInterface

Parameters:

nodeName - the compute node data-plane ID where the ACL is about to be written

theSff - the SFF to which the classifier is connected

theScfName - the name of the classifier

aclName - the name of the ACL

theIfName - the interface we want to classify

theAce - the ACE

Returns:

a List of FlowDetails having all the generated flows, which will be later installed

processReverseRsp

protected List<FlowDetails> processReverseRsp(RspName theRspName,
                                              String theScfName,
                                              String theAclName,
                                              String theNodeName,
                                              String theRuleName,
                                              long port,
                                              ServiceFunctionForwarder theSff)

Add the classifier flows for reverse RSPs.

Parameters:

theRspName - the RSP from which we want to derive the reverse RSP

theScfName - the name of the classifier who will process this reverse RSP traffic

theAclName - the name of the ACL

theNodeName - the compute node name where we will install the classifier flows for the reverse RSP

theRuleName - the name of the ACE

port - the output port of the classifier node

theSff - the SFF to which the classifier is connected

Returns:

a List of FlowDetails having all the generated flows, which will be later installed

processReverseRspRelayFlow

protected Optional<FlowDetails> processReverseRspRelayFlow(String nodeName,
                                                           ServiceFunctionForwarder theSff,
                                                           SfcNshHeader reverseNsh,
                                                           String theFlowKey)

Return a FlowDetails object that represent the relay flow - i.e. how to exit the chain - if any.

Parameters:

nodeName - the nodeName where the flow will be installed. Should be on the first SFF of the chain - last of the reverse chain.

theSff - the SFF name where the flow will be installed

reverseNsh - the SfcNshHeader object having the related data for the reverse chain

theFlowKey - the name of the analogous 'in' flow

Returns:

a FlowDetails object if possible, and empty Optional otherwise
