Named data network content storage pool based on neural network

Abstract

The invention provides a named data network content storage pool based on a neural network. The named data network content storage pool comprises an on-chip storage unit and an off-chip storage unit.The on-chip storage unit uses a high-speed memory, a neural network model is deployed in the on-chip storage unit to realize the uniform mapping of the data names, and an improved bitmap is deployed to map the data packets containing the same name prefixes into a same bucket. The off-chip storage unit uses a low-speed memory, a plurality of dynamic memories corresponding to the slots of a dynamicindex unit of an improved bitmap are deployed on the off-chip storage unit to store the skip table information of each name prefix, and the skip table information is used for guiding the next searchof the same name prefix Data packets in a bidirectional skip table so as to improve the data retrieval speed; and a bidirectional skip list structure is deployed additionally to store the storage position information of the data packet in a learning bitmap content storage pool, and each bidirectional skip list node stores a first-in first-out queue FIFO single pointer and the least recently used LRU double pointers.

Description

technical field [0001] The invention belongs to the field of high-performance router structure design, and is particularly aimed at the design of a new storage structure and algorithm of a content storage pool (Content Store) in the forwarding plane of a named data network. Background technique [0002] With the explosive growth of the scale of the Internet, the continuous emergence of innovative technologies and computing models has accelerated the transformation of the role of the Internet from a "communication channel" to a "data processing platform". In order to meet the future business needs of Internet content, personalization, ultra-high mobility, "zero" delay, ultra-high traffic density, etc., and completely solve many problems brought about by the current Internet IP architecture, a content cache is featured , Naming Data Network applications for communication content. [0003] NDN can not only realize the content-oriented communication mode of the Internet through...
