Embodiment Construction

[0049] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0050] The flowchart of an embodiment of the cache sharing method of the present invention is as follows image 3 shown.

[0051] In step 301, when the scheduled detection time arrives, the process of queue management is triggered to determine the type of data packets stored in the temporary buffer queue between the current time and the last scheduled detection time. In an embodiment, the predetermined detection period may be 100-200 ms, and there is a predetermined detection period difference between adjacent predetermined detection moments. A list of data packet types can be generated, and all data packet types of the data packets in the temporary buffer queue can be listed without repetition. The data packet type may refer to the operator type to which the data packet belongs, or may refer to the service type of t...

Abstract

The invention provides a cache queue sharing method and device, and relates to the technical field of communication, wherein the cache queue sharing method provided by the invention comprises the following steps of: determining the data packet types of data packets in a temporary cache queue, wherein the data packets stored in the temporary cache queue are data packets arriving within a predetermined detection period; and determining to abandon the data packets or store the data packets in the cache queue according to the protocol cache capacity of the data packet types in the cache queue, the size of the data packets corresponding to the data packet types in the temporary cache queue and the cached data size of the data packets corresponding to the data packet types in the cache queue. By means of the method provided by the invention, the data packet types received within the predetermined detection period can be judged; whether the data packets are stored in the cache queue or not is judged based on the data packet types; therefore, batch caching of the data packets in different types can be realized; and thus, sharing and isolating of the cache queue can be realized.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a cache sharing method and device. Background technique [0002] The main idea of ​​NFV (Network Function Virtualization, Network Function Virtualization) is to replace the existing dedicated hardware platform with a general-purpose hardware platform and software-based virtual function modules. In addition, CAPEX (Capital Expenditure, capital point) and OPEX (Operating Expense, operating costs) are reduced through the sharing of computing, network, and storage resources. At present, NFV research mainly focuses on the core network side. [0003] On the access network side, RAN (Radio Access Network, Radio Access Network) Sharing is currently a major research direction of 3GPP. It studies various scenarios in which multiple operators share wireless base station resources to meet the needs of operators. Dynamic way of cooperation. [0004] Both of the above two technical so...
