# Ok, other _json strings will have more regular structure and some variable data,
# so we will be using templates heavily.
# First off, there is segment describing PCC which conatins IP address but is otherwise constant.
# So the top-level template will look like this:
- json_templ = Template('''{
+ json_templ = Template(

"network-topology-pcep:path-computation-client": {
"ip-address": "$IP",

# The _json variables will differ only in $LSPS, but $IP will be present inside.
# Thus, the $IP substitution will come last, and any auxiliary substitutions before this final one
# will have to use safe_substitute().
# Discussion amout delegated and instantiated implies that $LSPS is either a single delegated LSP
# or a pair of delegated and instantiated (separated by comma) LSPS, in appropriate state.
# Of course, one LSP always follow a structure, for which here is the template:
- lsp_templ = Template('''

+ """
{
"name": "$NAME",
"path": [
}
}
]
- }''')
+ }"""
+ )
# IDs were already talked about, IP will be set last. Now, $NAME.
# Pcc-mock uses a fixed naming scheme for delegated tunnels, so one more template can be written,
# but it is so simple we can write just the one-line code instead:
- delegated_name = 'pcc_' + mininet_ip + '_tunnel_1' # 1 == ID
+ delegated_name = "pcc_" + mininet_ip + "_tunnel_1" # 1 == ID
# For the instantiated tunnel, user is free to specify anything, even charachers such as \u0000 work.
# But as we need to plug the name to XML, let us try something more friendly:
- instantiated_name = 'Instantiated tunnel' # the space is only somewhat evil character :)
+ instantiated_name = (
+ "Instantiated tunnel" # the space is only somewhat evil character :)
+ )
# What is CODE? The NAME in base64 encoding (without endline):
