Logic network establishing method based on functional blocks

Abstract

The invention discloses a logic network establishing method based on functional blocks. The method includes the steps that an arrangement layer, a center control layer and a forwarding layer are defined for a logic network, the specific functional blocks are defined at each layer, and therefore logic network establishment from upper layer applications to bottom layer data forwarding is achieved; resource demands are sent through the specific arrangement layer to an RESTAPI server located in the center control layer; the RESTAPI server sends virtual node resource information to a conversion engine assembly located in a configuration layer, and logic network configuration information is calculated by the conversion engine assembly and sent to the control layer through an IF-MAP protocol; according to the logic network configuration information, the control layer finds physical nodes corresponding to the logic network configuration information and sends a virtual node creating notice to each physical node. By the adoption of the method, according to different upper layer applications, a bottom layer forwarding plane can establish a special logic network used by the upper layer applications all the time, and data isolation in a virtual network is achieved.

Description

technical field [0001] The invention belongs to the field of network communication, and in particular relates to a logical network construction method based on function blocks. Background technique [0002] With the rapid expansion of the Internet and other computer technology network applications, new features and new requirements are constantly emerging and changing, which requires that the new generation of network equipment should be flexible enough to quickly respond to new services and new needs; It is required that the new generation of network equipment should be sufficiently open, so that users can flexibly combine the opened resources to provide services with different network requirements. The network virtualization technology proposed by T.Anderson and others can well meet the needs of the modern Internet. Its core idea is to separate the network infrastructure from the network service items. The network service provider (Service Provider, SP) according to the us...
