4 | Conceptually NLSR is divided into four modules |
||
5 | |||
6 | 1. Core |
||
7 | 2. Communication |
||
8 | 3. Routing |
||
9 | 4. Security |
||
10 | |||
11 | ### 1. Core Module |
||
12 | 4 | A K M Mahmudul Hoque | - [[Read and parse configuration file]] |
13 | 1 | Lan Wang | - Stores all configurable parameter values |
14 | - Stores Adjacent in Adjacency list |
||
15 | - Stores advertising names in name prefix list |
||
16 | 9 | A K M Mahmudul Hoque | - [[Establish connection with NDN Forwarder]] |
17 | 5 | A K M Mahmudul Hoque | - [[Establishing Adjacencies with neighbors]] |
18 | 6 | A K M Mahmudul Hoque | - [[Build LSAs]] |
19 | 7 | A K M Mahmudul Hoque | - [[Stores Link State Advertisement (LSA) in Link State Database (LSDB)]] |
20 | 1 | Lan Wang | |
21 | ### 2. Communication Module |
||
22 | 11 | A K M Mahmudul Hoque | - [[Creates CronoSync connection]] |
23 | 1 | Lan Wang | - Handles synchronization logic of NLSR's LSDB updates |
24 | 10 | A K M Mahmudul Hoque | - Publishes LSDB updates in router name |
25 | 1 | Lan Wang | - Upon update notification send interest for LSAs |
26 | 10 | A K M Mahmudul Hoque | - Publishes certificates updates |
27 | 1 | Lan Wang | - Send interest to fetch certificates |
28 | - Processes all inbound/outbound interest/data of NLSR |
||
29 | |||
30 | ### 3. Routing Module |
||
31 | - Calculate routing table ( depending configuration use link - state routing calculator or Hyperbolic routing calculator) |
||
32 | - Stores routing table |
||
33 | - Creates and store Name prefix table ( Name prefix table entry is Name Prefix with nexthops list to reach that name) |
||
34 | |||
35 | ### 4. Security Module ( This module will no longer be available later when NLSR will use NFD's rule based validator) |
||
36 | - Fetch, validate and stores certificate in Certificate Store |
||
37 | - If some certificate is fetched but waiting to be validated is recorded in waiting list |
||
38 | - After validation it is added in the certificate store otherwise discarded |
||
39 | - Validate each piece of data received by NLSR |
||
40 | - Sign data using router process keys before sending out |
