Embodiment approach

[0141] The present invention realizes the fast compression processing operation of data, the key is that in the Content Store, the network mapping of the neural network is used to improve the storage efficiency and support different name data retrieval algorithms, and the design meets the special two-way jump table data structure that supports the fast cache replacement strategy and a dynamic memory data structure that directs data retrieval. Its specific design and implementation plan are as follows:

[0142] (1) Data structure design of two-way jump table that quickly supports cache replacement strategy

[0143] The bidirectional jump table data structure designed in the present invention is improved on the basis of traditional skip tables, so the bidirectional skip table is similar to traditional skip tables, and also adopts a multi-layer structure, and each layer is composed of a two-way linked list, and its jump table The nodes are arranged in ascending order of the ID n...

Abstract

The invention provides a named data network content storage pool deleting method based on a neural network. An adopted storage pool comprises an on-chip storage unit and an off-chip storage unit. Theon-chip storage unit uses a high-speed memory, a neural network model is deployed in the chip to realize uniform mapping of data names, and an improved bitmap is deployed to map data packets containing prefixes of the same name into the same bucket. An off-chip storage unit uses a low-speed memory to deploy a plurality of dynamic memories corresponding to the slot slots of the dynamic index unit of the improved bitmap to store skip table information of each name prefix for guiding the next search of the same name prefix Data packet in the bidirectional skip table. And a bidirectional skip liststructure is deployed. The patent provides a method for deleting an Interest packet in the storage pool, and a method for deleting the Data packet in the storage pool.

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...
