Embodiment Construction

[0023] A non-limiting embodiment is given below in conjunction with the accompanying drawings to further illustrate the present invention.

[0024] refer to Figure 1-Figure 8 As shown, 1. Data model design: Cassandra's original data model is similar to a four-dimensional or five-dimensional HashMap such as figure 1 shown. Column is the smallest data unit of Cassandra, which consists of three elements: name (attribute name), value (value), timestamp (timestamp), where name and value are both byte[] types in Java, and the data of timestamp is Cassandra is automatically generated to record the writing time of data; SuperColumn is an array of Columns, including a name and multiple corresponding Columns; ColumnFamily is a structure containing many Rows (rows), which is equivalent to a table in a database. Row is composed of Key (key value) and Column associated with this Key; Keyspace contains multiple ColumnFamily, and you can specify the backup strategy and number of backups f...

Abstract

The invention discloses a distributed network awareness information storage and query system. The distributed network awareness information storage and query system comprises a user operation interface, an interface layer, an execution layer and a storage layer, wherein the user operation interface is used for accomplishing interaction between a user and the system, and the user carries out storage operation and query operation on dynamic information and static information through the user operation interface; the interface layer is used for receiving or submitting network awareness information stored or queried by the user, and identifying an operation instruction of the user, and comprises a query interface and a storage interface; the execution layer is used for analyzing a data access request of the upper layer, converting the data access request into an internal request of the system, and processing the internal request, and comprises a weak-reading interface, a locating reading interface, an identification interface, a weak-writing interface, a strong-writing interface and a reading repair interface, wherein the locating reading interface and the identifying interface are newly added on the basis of original interfaces of the Cassandra; the storage layer is used for storing the dynamic information and the static information. According to the distributed network awareness information storage and query system, the system load and the network overheads are reduced, and efficiency of storage of the network awareness information is improved.

Description

technical field [0001] The invention relates to data storage and query, specifically a data storage and query system based on a distributed system Cassandra for network perception information. Background technique [0002] In the current Internet, for network management, network security and other goals, it is necessary to implement various network performance measurements, traffic measurements, fault monitoring, etc. on the Internet. At the same time, it is also necessary to perform perception measurements on application services in the network. However, in the future network, network awareness is not only a basic capability of the network, but also an innovative network service and application. When the connotation of network awareness extends from resource awareness and state awareness to content awareness, application awareness, location awareness, and context awareness, various awareness services will bring a strong impetus to network innovation and application innovati...
