Abstract
(EN)
A mapper (50) includes circuitry configured to receive data streams each or which is a stream of data based on a calendar function associated with one of Flexible Ethernet (FlexE) or Metro Transport Networking (MTN); and circuitry configured to perform mapping of each of the data streams and to provide an output of the mapping to a device in a wireless data plane for transmission over one or more wireless links (102). The mapping can include packet mapping where the stream of blocks is encapsulated into packets. The mapping can include byte mapping where the stream of blocks is converted into a byte stream that is provided to a Radio Link Control (RLC) layer that guarantees byte delivery in order at a receiver. The mapping can also include bit mapping wherein the stream of blocks is transferred as a stream of bits to a transport buffer Service Access Point (SAP).
(FR)
Dispositif de mise en correspondance (50) comprenant des circuits conçus pour recevoir des flux de données, chacun étant un flux de données basé sur une fonction de calendrier associée à un Ethernet flexible (FlexE) ou à un réseau de transport de métro (MTN) ; et des circuits conçus pour effectuer une mise en correspondance de chacun des flux de données et pour fournir une sortie de la mise en correspondance à un dispositif dans un plan de données sans fil pour une transmission sur une ou plusieurs liaisons sans fil (102). La mise en correspondance peut comprendre la mise en correspondance de paquets où le flux de blocs est encapsulé en paquets. La mise en correspondance peut comprendre une mise en correspondance d'octets dans lequel le flux de blocs est converti en un flux d'octets qui est fourni à une couche de contrôle de liaison radio (RLC) qui garantit la distribution d'octets dans l'ordre au niveau d'un récepteur. La mise en correspondance peut également comprendre une mise en correspondance de bits, le flux de blocs étant transféré sous la forme d'un flux de bits à un tampon de point d'accès de service (SAP) de transport.
