Abstract: A method for reading and writing a forwarding information base, including receiving a write an associated data (AD) request used to modify the AD and a write a keyword (Key) request used to modify the Key corresponding to the AD, and before the write AD request and the write Key request pass through a cache, transforming, when any one stage to be read and written includes the Key, a row address in the write AD request into a row address that is same as a row address of a node block on which the Key is located, or transforming, when any one stage to be read and written does not include the Key, a row address in the write AD request and a row address in the write Key request into a same row address in the any one stage.

Abstract translation: 一种用于读取和写入转发信息库的方法，包括接收用于修改AD的写入关联数据（AD）请求和写入用于修改与AD对应的密钥的关键字（密钥）请求，以及在写入之前 AD请求和写密钥请求通过缓存，当任何一个读取和写入阶段包含Key时，将写AD请求中的行地址转换为与节点块的行地址相同的行地址 Key所在的位置或变换，当任何一个读取和写入阶段不包括Key时，写入AD请求中的行地址和写入密钥请求中的行地址在任何一个相同的行地址中 一个阶段

Abstract: The disclosure relates to a transmitting communication apparatus and a receiving communication apparatus of a non-coherent communication system. The transmitting communication apparatus is configured to communicate with the receiving communication apparatus via a communication channel. The transmitting communication apparatus comprises a processing circuitry configured to: map a sequence of data bits into a modulation symbol of a plurality of modulation symbols defined by a modulation constellation, wherein the modulation constellation is defined by a tiling of a Grassmannian manifold into a plurality of cells and a Cartesian product of a plurality of auxiliary constellations, wherein the Cartesian product of the plurality of auxiliary constellations is mapped onto each cell of the plurality of cells and each auxiliary constellation defines a plurality of auxiliary symbols. The processing circuitry is further configured to transmit a modulated signal based on the modulation symbol via the communication channel to the receiving communication apparatus.
