Embodiment Construction

[0088] Next, the technical solutions in the embodiments of the present invention will be described in the following examples of the embodiments of the present invention, and it is apparent that the described embodiments are merely embodiments of the invention, not all of the embodiments. Based on the embodiments of the present invention, there are all other embodiments obtained without making creative labor without making creative labor premises.

[0089] In the communication network, the data can be identified by a string, such as the NAMED DATANETWORKING, NDN, and the content (DATA) is identified by the name (that is, a string or interterest) instead of storage content. The network node is also the address of the destination host. When the data requestor wants to get a data, you can send a acquisition request with a string with identifier that identifies this data. This acquisition request does not have the specified receiver, such as NDN, and the content request party Get Reque...

Abstract

The embodiment of the present invention discloses a character string filtering method and a related device. An interface filtering device is provided for a network node, and the interface filtering device includes a first filtering component and a character string prefix storing data related to the network node. The second filtering component, the interface filtering device can receive the acquisition request sent by the data requester before the network node, and match the character string to be identified carried in the acquisition request according to the saved character string and character string prefix, if the character string to be identified If any character string or character string prefix in the interface filtering device can be matched, it can be determined that the data requested in the acquisition request is related to the network node. It can be seen that the request can be effectively obtained through the interface filtering device. Data that has nothing to do with the network node The acquisition request is filtered to ensure that the data requested by the acquisition request that the network node needs to process is related to the network node, thereby improving the utilization rate of the network node's processing resources.

Description

Technical field [0001] The present invention relates to the field of data processing, and more particularly to a string filtering method and related device. Background technique [0002] In the communication network, the data can be identified by a string, saving a network node having data, can record the string corresponding to the saved data. When the data request side wants to get a data, it is possible to send a acquisition request with a string with the identity of this data. The network node receiving the acquisition request can match the string of the acquisition request to the string recorded, if the match is successful, the network node has the ability to provide this data to the data request. [0003] However, under most requests, the data request party is not transmitted to the specified network node, but propagates the acquisition request, such as broadcast, and any one of the network nodes saving data can receive the acquisition request. However, it is not that each ...
