[Mini-NDN] convergence time

[sepehr abdous]

Thank you for your response

about (2) as I'm working with mini-ndn, mini-ndn creates nlsr itself based
on the minindn.conf and I do not exactly know how to change minindn.conf so
that in nlsr.conf created by running minindn we have the hello interval of
15 as it's default value is 60.

here is my minindn.conf:

[nodes]
node4: _ hyperbolic-state=off radius=0.0 angle=0.0 network=/ndn
router=/%C1.Router/cs/node4 site=/edu/site nlsr-log-level=INFO
max-faces-per-prefix=0 nfd-log-level=INFO
node6: _ hyperbolic-state=off radius=0.0 angle=0.0 network=/ndn
router=/%C1.Router/cs/node6 site=/edu/site nlsr-log-level=INFO
max-faces-per-prefix=0 nfd-log-level=INFO
node1: _ hyperbolic-state=off radius=0.0 angle=0.0 network=/ndn
router=/%C1.Router/cs/node1 site=/edu/site nlsr-log-level=NONE
max-faces-per-prefix=0 nfd-log-level=NONE
node2: _ hyperbolic-state=off radius=0.0 angle=0.0 network=/ndn
router=/%C1.Router/cs/node2 site=/edu/site nlsr-log-level=INFO
max-faces-per-prefix=0 nfd-log-level=INFO
node5: _ hyperbolic-state=off radius=0.0 angle=0.0 network=/ndn
router=/%C1.Router/cs/node5 site=/edu/site nlsr-log-level=INFO

node3: _ hyperbolic-state=off radius=0.0 angle=0.0 network=/ndn
router=/%C1.Router/cs/node3 site=/edu/site nlsr-log-level=INFO
