# Named-data Link State Routing(NLSR) 

 **Named-data Link State Routing (NLSR)** is routing for NDN under development. 

 NLSR's development is going on top of  

 * [**ndn-cpp-dev**](https://github.com/named-data/ndn-cpp-dev) 
 * [**NFD**](http://redmine.named-data.net/projects/nfd/wiki) 
 * [**ChronoSync**](https://github.com/bruinfish/ChronoSync) 

 ### UML of NLSR is available at [**NLSR-UML**](http://irl.cs.ucla.edu/~cawka/nlsr/) 


 ## NLSR's design 

 Conceptually NLSR is divided into four modules 

 1. Core 
 2. Communication 
 3. Routing 
 4. Security 

 ### 1. Core Module 
 - Read and parse configuration file 
 - Stores all configurable parameter values 
 - Stores Adjacent in Adjacency list 
 - Stores advertising names in name prefix list 
 - Stores Link State Advertisement (LSA) in Link State Database (LSDB) 

 ### 2. Communication Module  
 - Handles synchronization logic of NLSR's LSDB updates 
 - Publish LSDB updates in router name 
 - Upon update notification send interest for LSAs 
 - Publish certificates updates 
 - Send interest to fetch certificates 
 - Processes all inbound/outbound interest/data of NLSR
