Embodiment Construction

[0040]The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0041] The flowchart of an embodiment of the cache sharing method of the present invention is as follows image 3 shown.

[0042] In step 301, when a new data packet is received, the process of queue management is triggered to determine the type of the incoming data packet. The data packet type may refer to the operator type to which the data packet belongs, or may refer to the service type of the data packet.

[0043] In step 302, it is determined to discard or store the data packet in the buffer queue according to the protocol buffer capacity corresponding to the data packet type in the buffer queue, the size of the data packet, and the buffered data volume of the corresponding type of data packet. Each data packet type can have a certain protocol buffer capacity or protocol buffer ratio in the buffer queue. The pr...

Abstract

The invention provides a cache sharing method and device, and relates to the technical field of communications. The cache sharing method of the invention comprises the following steps: receiving a data packet, and judging the type of the data packet, wherein the data packet type comprises an operator corresponding to the data packet or the business type of the data packet; determining whether to abandon the data packet or store the data packet in a cache queue according to the corresponding protocol cache capacity of the data packet in the cache queue, the size of the data packet and the cached data volume of the data packet of the corresponding type. The method disclosed by the invention comprises the following steps: judging the operator or the business type corresponding to the received data packet, judging whether to store the data packet in the cache queue based on the operator or the business type corresponding to the data packet, thereby performing cache handling on the data packet in a classification way; and the sharing and the isolation of the cache queue are 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...
