Abstract

The invention discloses a method and a system for dynamically allocating network resources of a cloud data center. The method comprises the following steps: receiving a network service demand of a user through a network resource arrangement module of a cloud data center, obtaining a plurality of service chains according to the network service demand, and sending each service chain to a network equipment control module; interpreting the received service chains by using a network equipment control module to obtain control flow tables in one-to-one correspondence with the network nodes in the service chains, and sending the control flow tables to the corresponding network nodes; wherein the control flow table comprises network service requirements; and forwarding the data by using the networknode according to the control flow table to realize dynamic allocation of resources. According to the method and the system, the network arrangement module is utilized to obtain the corresponding service chain, the network equipment control module is utilized to obtain the control flow table according to the service chain, the control flow table is issued to the network node in advance, and dataforwarding is performed according to the issued control flow table, thereby realizing dynamic allocation of network resources.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and system for dynamically allocating network resources of a cloud data center. Background technique [0002] Cloud computing realizes the pooling of physical resources such as computing, storage, and network through virtualization technology, and provides users with on-demand resource services. The network solution of the current cloud data center is provided by the network components of the IaaS (Infrastructure as a Service, infrastructure) platform to provide resource arrangement for users through the northbound interface, directly integrate OVS and physical switches through plug-ins, and have a layer-2 network, IP address management, Layer 3 routing, VPN, firewall and other service capabilities to provide users with network virtualization services, allowing tenants to create and manage virtual networks. [0003] However, the extensibility of the data ...
