In telecommunications and networking, a mapper is a device or software function that converts data from one format or protocol to another. It typically takes payloads from a local network and encapsulates them for transport over a wide-area protocol, such as mapping Ethernet frames into a SONET payload. Mappers ensure that addressing schemes and data structures align correctly across disparate network boundaries.
Check the configuration on the Ethernet mapper; we're dropping frames before they even hit the SONET ring.
En español sencillo Compruebe la configuración en el mapper de Ethernet; estamos perdiendo tramas antes de que lleguen al anillo SONET.
Los mappers de hardware suelen estar integrados en los routers de borde o en los nodos de transporte donde las redes de área local se conectan con las redes de transporte de los operadores.
