vew: Enable forwarding_path enforcement about son-sp-infrabstract

[mpeuster]

Implement VimEmuNetwork wrapper, like: https://github.com/sonata-nfv/son-sp-infrabstract/blob/master/vim-adaptor/adaptor/src/main/java/sonata/kernel/vimadaptor/wrapper/ovsWrapper/OvsWrapper.java

Use VNFRs to get interface names of containers (might require extension of vim-emu compute start API, to be checked)

Todos:

• Assemble and send NetworkConfigurePayload on Messagebroker (VIMEmuIntegrationTest)
• Translate NetworkConfigurePayload into API calls on vim-emu
• Answer?

[frederictobiasc]

Relevant topics according to AdaptorDispatcher are:

• infrastructure.service.chain.configure
• infrastructure.service.chain.deconfigure

Is instance_uuid really defined in vnfd? Ex:

son-sp-infrabstract/wim-adaptor/adaptor/YAML/firewall-vnfd.yml

Line 54 in a310720

instance_uuid: 6a15313f-cb0a-4540-baa2-77cc6b3f0000

• Discuss possible inconsistency between ServiceDescriptor-Class and service descriptor model.
  Answer: As the SP invokes infrastructure.service.chain.configure, a uuid and the instance_uuid has to be provided. This is attached to the message body. VIMEmuIntegrationTest simulates this behaviour by setting uuid during the test. Further information is provided in the comments in VIMEmuIntegrationTest.java
  Suggestion: Use well-defined messages.
• Request documentation of ConfigureNetworkCallProcessor; Actually, it seems to be only working for prepared test cases with modified VNFDs (manually added instance_uuid, like mentionend in workaround)

[frederictobiasc]

• fix failed repo writing due to missing serviceInstance_uuid https://github.com/frederictobiasc/son-sp-infrabstract/blob/82cba693f3adfd4ed99d1fa37d88a9791b723a96/vim-adaptor/adaptor/src/main/java/sonata/kernel/vimadaptor/wrapper/vimemu/VIMEmuComputeWrapper.java#L155

[frederictobiasc]

• vnfr connection point has to correspond to vnfd connection points in Forwarding Graph -> redesign VIMEmuComputeWrapper

Fixed in: b9c6956

• test connectivity between deployed containers
  • ICMP (ping)
  • TCP (http)
