| 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. |
| |
| 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 |
