-Installation:
-
-1: Getting NLSR:
-
-https://github.com/NDN-Routing/NLSR0.0
-
-2: run make to compile.
-
-3: Start ccnx daemon (ccnd) and Repo (ccnr).
-
-4: Add '/ndn/keys' route to your neighboring testbed nodes.
-This can be done by adding routes in your ccnd.conf to all neigbors,
-e.g.
- add /ndn/keys udp 10.0.XX.XX
- add /ndn/keys udp 10.0.YY.YY ...
- add /ndn/keys udp 10.0.ZZ.ZZ
-
-5: Create your keys and publish them through repo. Please have
- a look at https://github.com/named-data/ndn-testbed-key-suite for details.
-
-6: create a nlsr configuration file, have a look at
- macbook.conf and 'Configuration Parameters' section for details
-
-7: start nlsr
-
-
-Configuration Parameter:
-
-1. router-name </name/prefix/of/the/router>
-It is a required configuration parameter that is used to set the router name.
-Name prefix of the router must start with `/ndn' and followed by a strict
-hierarchical order of name components up to the hostname of the router. For
-e.g. if router has a hostname host.dept.org.edu pollux.cs.memphis.edu then the
-router name can be `/ndn/org.edu/dept/host..
-
-2. ccnneighbor </name/prefix/of/neighbor> [neighbor_ip_addrr]
-This parameter is used to configure the neighboring router. Name prefix of a
-neighbor must start with `/ndn. and followed by a strict hierarchical order of
-name component as mentioned for router-name. If a router has a neighbor having
-hostname `neighbor.dept.org.edu' then configuration command would be
-`ccnneighbor /ndn/org.edu/dept/neighbor. The optional parameter,
-[neighbor_ip_addrr], can be provided for explicitly connecting to a given
-IP. This is useful if there is no entry of the hostname in the DNS.
-
-3. ccnname </name/prefix/to/be/advertised>
-ccnname is used to advertise the name prefix of the services hosted by the
-router. Name prefix must follow the ccnx naming convention.
-
-4. topo-prefix <name/prefix/of/repo/topo>
-It is used to configure the topological prefix of the `sync. slice created for
-nlsr in a repo. Prefix must follow the ccnx naming convention. Default value
-for topo prefix is `/ndn/routing/nlsr'
-
-5. slice-prefix <name/prefix/of/repo/slice>
-This parameter is used to set the sync's slice prefix. All nlsr nodes `must'
-have the same slice prefix and must follow the ccnx naming convention. Default
-value for slice prefix is `/ndn/routing/nlsr/LSA'
-
-6. lsa-refresh-time <sec>
-It is the time in seconds, after which router will refresh its LSAs. Default
-value = 1800 sec, Min = 240 sec
-
-7. router-dead-interval <sec>
-It is the time after which router will consider its neighbor dead if it does
-not hear anything for that amount of time. If an LSA generated by neighbor has
-a lifetime greater than router-dead-interval then router will simply discard
-the LSA and update name prefix table, routing table and ccnd FIB accordingly.
-Default value = 3600 sec, Min = 360 sec.
-
-8. interest-retry <number>
-interest-retry is maximum number of times a router will send same interest if
-the interest is timed out. Default = 3, Min =1 and Max = 10
-
-9. interest-resend-time <sec>
-When an interest is timed out, NLSR waits for `interest-resend-time. before
-sending another interest. The interest is retransmitted up to the value of
-`interest-retry.. If the interest doesn.t get satisfied during this time the
-neighbor will be considered as dead. Default value = 15 sec, Min = 1 sec, Max =
-60 sec
-
-10. max-faces-per-prefix <number>
-By default NLSR calculates and add faces for all available faces to a prefix.
-Number of faces can be restricted with this parameter, if this is configured
-NLSR will add <number> or faces per prefixes in ccnd FIB.
-
-11. debug <on/off>
-Enable nlsr debugging by printing out detail messages on the standard output.
-By default it is off.
-
-12. logdir </directory/for/logging/>
-NLSR will start writing log in logdir folder. If logdir is not configured NLSR
-will create a log directory name nlsrLog in user home directory and write log
-into that folder.
-
-13. tunnel-type <udp | tcp>
-This is used to specify the tunnel type that NLSR should create for building an
-overlay network. By default NLSR creates udp tunnels.
-
-**Following Commands are only required for hyperbolic routing**
-
-14. hyperbolic-routing <on|dry_run>
-This option enables hyperbolic routing. With option on, link state routing
-doesn't work while with dry_run option route is calculated by Link State
-routing and hyperbolic routes are just recorded only in log file.Following
-field is required if hyperbolic routing is on.
-
-15. hyperbolic-cordinate <radius> <theta>
-Polar coordinates of a node in a form of radius and theta. Currently, calculation
-of the polar coordinates is an offline process and done by
-the operator of a site.
-
-** Hyperbolic Commands End here **
-
-16. keystore-path </path/to/keystore/file name(.ccnx_keystore)>
-Path to the keystore. The keystore folder is usually created by
-ccninitkeystore. Keys in this folder will be used by NLSR to sign the packets.
-
-17. root-key-prefix </key/prefix>
-Name prefix of the root key; the site key should be signed by this key.
-e.g. root-key-prefix /ndn/keys
-
-18. site-name </name/prefix/of/site>
-Name of the site of which this router is a part.
-
-19. network </name/of/network>
-Name of the networks router belongs to
