| http://dbpedia.org/ontology/abstract | ITU-T Recommendation G.709 Interfaces for … ITU-T Recommendation G.709 Interfaces for the Optical Transport Network (OTN) describes a means of communicating data over an optical network. It is a standardized method for transparent transport of services over optical wavelengths in DWDM systems. It is also known as Optical Transport Hierarchy (OTH) standard. The first edition of this protocol was approved in 2001. The G.709 OTUk signal is positioned as a server layer signal for various client signals, e.g. SDH/SONET, ATM, IP, Ethernet, Fibre Channel and OTN (where k=0, 1, 2, 2e, 3, 3e2, 4 or flex). Work on support for InfiniBand and Common Public Radio Interface client signals is currently in progress. The frame structure defined in G.709 is constructed of 4 areas: 1. * is the area in which payload is mapped. 2. * contains the OPUk with additional overhead bytes (e.g. TTI, BIP8, GCC1/2, TCM etc.). 3. * OTUk is the section and includes framing, TTI, BIP8 and GCC0 bytes. 4. * FEC – The standard FEC code (described in ) is a Reed–Solomon coding calculated across the payload (OPU) columns. This allows detection and correction of bit errors due to signal impairments during transmission. The FEC code also extends the distance the optical signal can travel before requiring regeneration. G.709 offers advanced OAM&P capabilities such as (TCM), End to End performance monitoring, connectivity monitoring, signal quality supervision and General Communication Channel (GCC).n and General Communication Channel (GCC). , La recomendación de ITU-T G.709 Interfaces … La recomendación de ITU-T G.709 Interfaces para la Red de Transporte Óptica (OTN) describe un medio para comunicar datos a través de una red óptica. Es un método estandarizado para el transporte transparente de servicios sobre longitudes de onda ópticas en sistemas DWDM. También se conoce como Jerarquía de Transporte Óptico (OTH) estándar. La primera edición de este protocolo se aprobó en 2001. La señal G.709 OTUk se posiciona como una señal de capa de servidor para varias señales de cliente, p. ej. SDH/SONET, ATM, IP, Ethernet, Canal de Fibra y OTN ODUk (dónde k=0, 1, 2, 2e, 3, 3e2, 4 o flex). Actualmente, se está trabajando en la compatibilidad con señales de cliente de InfiniBand y Interfaz Radiofónico Público Común. La estructura del marco definida en G.709 se compone de 4 áreas: 1. * OPUk Es el área en la que se asigna la carga útil. 2. * ODUk Contiene el OPUk con bytes adicionales de sobrecarga (p. ej. TTI, BIP8, GCC1/2, TCM etc.). 3. * OTUk Es la sección e incluye marcos, TTI, BIP8 y bytes GCC0. 4. * FEC – El estándar FEC (descrito en G.975) es una codificación Reed–Solomon calculada en las columnas de carga útil (OPU). Esto permite la detección y corrección de errores de bits debidos a alteraciones de la señal durante la transmisión. El código FEC también extiende la distancia que la señal óptica puede viajar antes de requerir regeneración. G.709 ofrece capacidades avanzadas de OAM&P como Monitoreo de Conexión del Tándem (TCM), Monitoreo de rendimiento de extremo a extremos, Monitoreo de conectividad, Supervisión de calidad de señal y Canal de comunicación general (GCC).ñal y Canal de comunicación general (GCC). |
