Mapping a community network

Abstract

Community networks are self-organized networks which exist all around the world. For a large number of users, they are the only form of communication in the community itself and with the Internet. All community networks maintain some database where all information about the nodes in the community network is stored. The database information is manually inserted in the database, which commonly leads to a mismatch between the documentation and reality. In this paper we present a dynamic community network mapper, complementary to the node database. We explain the goals of this approach, show the challenges and steps we took to realize such a mapper, and give initial results.

Mitigación de vulnerabilidades en la red central de un ISP: Un caso de estudio

“…Protocolo de descubrimiento de vecinos MikroTik (MNDP, por sus siglas en inglés) y el protocolo de descubrimiento en capa de enlace (LLDP, por sus siglas en inglés): permiten encontrar otros dispositivos compatibles con MNDP o CDP (Protocolo de descubrimiento de Cisco) o LLDP en el dominio de difusión de Capa 2 (Braem et al, 2014). Este protocolo trabaja en UDP/5678, es de gran utilidad para un administrador de red, ya que permite visualizar la topología de red en capa 2, donde brinda información muy relevante de los dispositivos encontrados como son: ip-address, mac-address, identidad (nombre), versión del soware y tipo de hardware.…”

“…Among them are routing [14][15][16], security [17], and analyses of topologies, performance, mobility [18][19][20][21][22]. But research into community network management solutions and best practices still remains scarce.…”
