Problems solved by technology

[0006] If multiple users request the same data in time-division, regardless of whether wavelength division multiplexing technology or IP multicast technology is used, the same data needs to be transmitted repeatedly through the backbone network, resulting in bandwidth occupation of the backbone network

Embodiment Construction

[0024] There is a lot of repeated transmission of data in the network. For example, users in multiple places B need to obtain the same data transmitted from place A at different times, then the data must be repeatedly transmitted from place A to place B at different times according to the needs of users. to meet the needs of different users in B. In order to reduce the resulting bandwidth occupation of the backbone network, in the embodiment of the present invention, when a data access request is received, it is judged whether the requested data is stored locally in the access network, and if so, it will be stored in the access network The local data is sent to the user, otherwise, the data is acquired through the backbone network and sent to the user.

[0025] Wherein, it may also include: monitoring the number of times a certain data is acquired through the backbone network, and saving the data locally in the access network when the number reaches a predetermined number. Th...

Abstract

The present invention discloses a method for obtaining network data by users and a device realizing the same, wherein the method concretely comprises that: when a data access request is received, the fact that the data requested to be accessed is saved in local access network is judged; if yes, the data saved in the local access network is sent to a user; if not, the data is obtained from backbone network, and is then sent to the user; the technical proposal provided by the embodiment of the invention saves the data needed by the user in the local access network, thereby reducing bandwidth occupied by the same data repeatedly transmitted by a backbone network.

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to a method and equipment for enabling users to obtain network data. Background technique [0002] With the emergence of high-bandwidth services such as IPTV (Internet Protocol Television), video conferencing, online games, and HDTV (High Definition Television), users' demand for access bandwidth will further increase. FTTH (Fiber To The Home) technology solves the "last mile" bottleneck of broadband network access due to the use of optical fiber access, thus meeting the user's requirements for access network bandwidth. However, the development of access network technologies such as FTTH will lead to the bottleneck of the bandwidth of the backbone network. Therefore, increasing the bandwidth of the backbone network and improving the utilization rate of the backbone network will become the focus of network development in the next stage. [0003] At present, the...
