Embodiment Construction

[0056] In order to make the above objects, features and advantages more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0057]A method of using DHCP to assign IP addresses to data center nodes in a fat tree structure network according to the present invention. The method is aimed at the fat tree structure network topology. First, the DHCP server and client in the network are customized and transformed, and the IP addresses are determined by each The DHCP server in each Pod is allocated, and the network nodes are allocated layer by layer according to the number of hops away from the DHCP server. The switches in the pod that are not directly connected to the DHCP server provide relay services, and in order to avoid address allocation confusion, the core layer The address of the switch is only assigned by the DHCP server in a Pod, so as to realize the automatic allocation of n...

Abstract

The invention provides an automatic allocation method of an IP address of a node inside a fat tree structure networking data center. The automatic allocation method comprises the following steps of: firstly, carrying out DHCP (dynamic host configuration protocol) server initial configuration, modifying and self-customizing a DHCP server end and a client end in a network for supporting rule-based IP address allocation; and secondly, carrying out specific IP address allocation, and carrying out IP address allocation by a DHCP server in a Pod by layers by the network node according to the count of hops away from the DHCP sever, wherein a DHCP relay function is started by a switchboard in the Pod after an address is obtained. According to the allocation method, a data center network of a fat tree structure is combined with a DHCP, thus the automatic allocation of all node addresses in the data center network of fat tree structure networking is realized, the network abnormity problem can be detected and solved, a large quantity of manpower and material resources are saved, and normal and stable operation of the data center network is ensured.

Description

technical field [0001] The invention relates to the field of network technology, in particular to a method for automatically assigning IP addresses of internal nodes in a data center with a fat tree structure network. Background technique [0002] Data Center (Data Center), or Server Farm (Server Farm), refers to facilities for housing computer systems and related components (such as networks, storage systems), generally including redundant and backup power supplies, redundant data communication connections , environmental controls (such as air conditioners, fire extinguishers) and safety equipment, etc. Early data centers were mainly used to provide Internet basic platform services and various value-added services, so they were called Internet data centers (IDCs), and were usually managed and operated by specialized telecommunication business organizations to provide services. In recent years, with the development and progress of technologies such as Internet services, dis...
