Interface SnatService

All Known Implementing Classes:

SnatServiceImpl

public interface SnatService

SnatService interface provides the rules in SNAT table which is Table(40) for ovs pipeline. SNAT means Source Network Address Translation, it is acronym for network terminology. Handle the upward flows.

Method Detail

programRules

void programRules(org.onosproject.net.DeviceId deviceId,
                  org.onosproject.vtnrsc.SegmentationId matchVni,
                  org.onlab.packet.IpAddress srcIP,
                  org.onlab.packet.MacAddress ethDst,
                  org.onlab.packet.MacAddress ethSrc,
                  org.onlab.packet.IpAddress ipSrc,
                  org.onosproject.vtnrsc.SegmentationId actionVni,
                  org.onosproject.net.flowobjective.Objective.Operation type)

Assemble the SNAT table rules. Match: ipv4 type, vnid and source ip. Action: set eth_src, set eth_dst, set ip_src, set vnid and goto L2Forward Table(50).

Parameters:

deviceId - Device Id

matchVni - the vni of L3 network

srcIP - source ip

ethDst - external gateway mac

ethSrc - external port mac

ipSrc - floating ip

actionVni - external network VNI

type - the operation type of the flow rules
