NLSR

Configuration File Format¶

NLSR is configured using an INFO file.

Example configuration¶

; the router section contains the setting of network, site name 
; and router name which all together makes router-prefix

router
{
; mandatory configuration command section

    network /ndn         ; name of the network the router belongs to in ndn URI format
    site /memphis.edu    ; name of the site the router belongs to in ndn URI format
    router /cs/pollux    ; name of the network the router belongs to in ndn URI format
}

; the hello section describes the configuration settings for NLSR hello protocol

hello
{
; in case hello interest timed out, router will try 'retrials' times at 'interval' seconds
; interval before giving up for any neighbors (deciding link is down)     

   retrials 3                          ; interest retry number in integer. Default value 3
                                       ; valid values 1-10

   interval  1                         ; interest sending interval in seconds. Default value 1
                                       ; valid values 1-15

; neighbor command is used to configure router's neighbor. Each neighbor will need
; one block of neighbor command

   neighbor
   {
       name /ndn/memphis.edu/cs/castor        ; name prefix of the neighbor router consists
                                              ; of network, site-name and router-name

       face-uri  udp://castor.cs.memphis.edu  ; face id of the face connected to the neighbor
       link-cost 20.6                         ; cost of the connecting link to neighbor
   }
}

; the synchronization section contains all the configuration settings for router's update
; synchronization with neighbors in the network

synchronization
{
; all routers in the network must have same sync-prefix. Routers synchronizes routing updates
; in this prefix across the network. This prefix is routable to each neighbor from every router

    sync-prefix /ndn/nlsr/sync ; name in URI format. Default value /ndn/nlsr/sync

; lsa-refresh-time is the time in seconds, after which router will refresh its LSAs

    lsa-refresh-time 1800      ; default value 1800. Valid values 240-7200
}

; the hyperbolic section contains the configuration settings of enabling a router to calculate
; routing table using [hyperbolic routing table calculation](http://arxiv.org/abs/0805.1266) method

hyperbolic
{
; commands in this section follows a strict order
; the switch is used to set hyperbolic routing calculation in NLSR

    state off              ; default value 'off', set value 'on' to enable hyperbolic routing table 
                           ; calculation which turns link state routing 'off'. set value to 'dry-run"
                           ; to test hyperbolic routing and compare with link state routing.


    radius   123.456       ; radius of the router in hyperbolic coordinate system
    angle    1.45          ; angle of the router in hyperbolic coordinate system
}


; the fib section is used to configure fib entry's type to ndn FIB updated by NLSR

fib
{
; the tunnel configuration is used to set the tunnel type of the FIB entries by NLSR

    tunnel-type udp          ; default tunnel type is 'udp', set value to 'tcp' for TCP tunnel


; the max-faces-per-prefix is used to limit the number of faces for each name prefixes
; by NLSR in ndn FIB

    max-faces-per-prefix 3   ; default value 0. Valid value 0-60. By default (value 0) NLSR adds
                             ; all available faces for each reachable name prefixes in NDN FIB

}

; the advertising section contains the configuration settings of the name prefixes 
; hosted by this router

advertising
{
; the ndnname is used to advertised name from the router. To advertise each name prefix
; configure one block of ndnname configuration command for every name prefix.

    prefix /ndn/edu/memphis/cs/netlab           ; name in ndn URI format
    prefix /ndn/edu/memphis/sports/basketball 
}
