Hi Xiaodong and Julien,
today we tried to connect but there was no meeting on zoom and gotomeeting.
Can we schedule an on-line meeting in the next days?
Thanks,
Serena

Hi Xiaodong and Julien,
we plan to participate to the next call on zoom (on Monday 23/10).
Maybe we can discuss about this new feature during the call.
In the meanwhile, as Xiaodong asked, Verigraph needs a network service
descriptor containing node types already available in Verigraph's
catalogue, in order to load the correct function models and run the
verification process. Currently Verigraph supports some function
types, like firewall, NAT, endhost, web server, web cache, DPI, etc.
For each new node, we also need to pass its configuration to
initialize the function model (e.g. filtering rules for firewall).
Furthermore, since Verigraph checks the reachability between two nodes
of the network topology, we also need a way to specify what Verigraph
has to verify on a given network service (we generally name this kind
of information as "policies)". I notices that TOSCA already provides a
way to define a set of policies. So it would be useful if we can add a
new type of policy (e.g. verification policy) in order to pass the
required inputs to Verigraph.
thanks for your interest and help,
Serena

Hi, Julien and Serena.
I'am sorry missed Serena's email in my office mail, and i cann't find
the real reason. Please add my gmail in the receivers in the future,
thanks.
As julien said, adding tosca in verigraph is great ideal. From the
Tosca specification point of view, if the basic types(node type,
relationship type, requirement type, etc.) don't meet the
requirements, you can optionally add custom types as long as the
specification constraints can be satisfied, the point is how to use
the topology(defined with new types) parsed by tosca-parser.
We can discusse it again through email or usring meeting or irc. and
it will be better for our discussion if you could send your demand
ahead of schedule.

Hi Serena,
It's a great news for TOSCA supported in Verigraph. It will
make TOSCA template more useful and enhance Parser ecosystem.
Currently Parser is integrating with ONAP project.
If it is reasonable, we can add it in Parser project. Let's
discuss this issue in email or with a meeting.
Xiaodong, can you hold a team meeting using zoom?

Hi Shang, All,
we would like to add the support of TOSCA in Verigraph,
but we noticed
that our catalogue of network functions does not exactly
match with the
types of nodes offered by TOSCA. That is the reason why
we would kindly
ask you how we can add new node types in TOSCA and, in
turn, in Parser.
Thanks a lots.
Serena
