    The Named-data Link State Routing protocol (NLSR) is an intra-domain routing
    protocol for Named Data Networking (NDN). It is an application level protocol
    similar to many IP routing protocols, but NLSR uses NDN’s Interest/Data packets
    to disseminate routing updates, directly benefiting from NDN’s built-in data
    authenticity. The initial NLSR design, which was developed in 2013, has
    undergone significant changes. The new NLSR has been deployed on the NDN testbed
    since August 2014; its development helped drive the development of the
    trust/security functionality of NDN libraries as well as a number of features in
    NFD and ChronoSync. In this paper, we describe the current design and
    implementation of NLSR, with emphasis on those features that differentiate it
    from an IP-based link state routing protocol – (1) naming: a hierarchical naming
    scheme for routers, keys, and routing updates; (2) security: a hierarchical
    trust model for routing within a single administrative domain; (3) routing
    information dissemination: using ChronoSync to disseminate routing updates; and
    (4) multipath routing: a simple way to calculate and rank multiple forwarding
    options. Although NLSR is designed in the context of a single domain, its design
    patterns may offer a useful reference for future development of inter-domain
    routing protocols.
