Hi Raffo, The ESC talks to OpenStack using REST as far as I know. ESC also contains a ConfD instance which provides for NETCONF communication between NCS and ESC. However, these are ESC internals. I don't have a flow diagram to share with you right now. However, you can run the example and examine ncs-java-vm.log and correspond it to the code. I guess it would give you some idea about interaction between NCS and ESC. Thanks, Ajay ... View more

Hi Raffo, I haven’t run these examples but I think what you are saying is correct. There won’t be much difference in configs too between physical PE e.g. ASR1K and a virtual PE e.g. CSR1Kv. One of the addition in virtual-mpls-vpn example would be that, you’d see vm-manager-esc and vm-manager packages which deal with ,VM-releated NETCONF notifications from ESC e.g. VM_ALIVE notification, and also with subsequent addition of these Vms as devices (e.g. vPE). This is a sample implementation of Reactive Fast Map involving a VNFM such as ESC. I think there is another example for non-virtualized mpls-vpn which doesn’t involve esc (so that can be thought of exactly applicable to physical PEs (IOS & IOS-XR). However, just be aware that all the examples are using netsim devices built from IOS or IOS-XR NEDS. Thanks, Ajay ... View more

Hi Raffo, Have you tried virtual-mpls-vpn example in nso 4.0? It seems to have a simulated esc giving notifications back to main service package about instantiation of simulated VNFs. Thanks, Ajay ... View more

Hi Raffo, I think the "VM Manager" would be a NCS service package (java+template) which will communicate with VIM (e.g.  ESC) through the NED for VIM (e.g. NED for ESC). Hope that helps. Once NSO4.0 is released, it'll be clearer. Thanks, Ajay ... View more

Hi Eu, The NSO 4.0 release has/will-have a new example “virtual-mpls-vpn” which shows this. The example also includes the VM Manager. I'm trying to confirm the release dates of NSO 4.0 with the larger team. Will let you know ASAP. Thanks, Ajay ... View more

Hi Raffo, In the Juniper style (ncs_cli -u admin or ncs_cli -u admin -J), please try this :- edit devices device c1 config ios:interface FastEthernet 10/10 switchport trunk allowed vlan 1234 vlans 1234 Thanks, Ajay ... View more

Hi Eu, There are two ways to implement this :- 1. NCS (Orchestrator) <-> ESC(VNFM) <->OpenStack(VIM) . ESC brings in certain value addition in terms of VM health monitoring and dynamic scale-up/down of VMs. This is tested and production grade. or 2. NCS(Orchestrator)<->OpenStack(VIM) All it requires is an OpenStack NED. I think a PoC-level NED for OpenStack is currently available. Thanks, Ajay ... View more

Hi Eu, NCS 3.4.1 doesn’t have an in-built VNF Manager (ESC). Even if you install ESC, you’d need a package(java+template based) to talk to ESC, in NCS 3.4.1. As far as I know , NSO will be available at beginning of FY16 i.e. End of July. As you said, NSO = NCS (having the package that will talk to ESC) +  VNF Manager (ESC) Thanks, Ajay ... View more

Hi Eugenio, For tests or small PoC (comprising of few service instances), your configuration should be fine. For advanced PoCs or production, there are recommended configurations based on different parameters. Thanks, Ajay ... View more
