Embodiment Construction

[0039] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0040] figure 1 It is a flowchart of a data center scalable multicast method according to an embodiment of the present invention. The data center scalable multicast method of this embodiment includes the following steps:

[0041] S1: set a multicast forwarding table for each port of the switch in the data center, and set the total number of classifications of the multicast groups in the data center; the multicast forwarding table is used to store multicast entries, each A multicast entry is an element in the multicast forwarding table. Since it is uncertain whether each multicast group in the data center will generate an entry in a certain multicast forwarding table, each...

Abstract

The invention discloses an extensible multicast method of a data center and a system thereof and relates to the Internet technology field. The method comprises the following steps that: S1. Each port of a switchboard in the data center is provided with one multicast forwarding table and a total number of categories of a multicast group in the data center is arranged; S2. Through the total number of categories of the multicast group in the data center and a probability of occurrence of the each multicast group, the number of hash functions used in the each kind of the multicast group in the multicast forwarding table is calculated and the data center is established; S3. The port of the switchboard carries out matching according to the hash function corresponding to the kind of the port in the multicast forwarding table; if the matching succeeds, a data packet is forwarded; otherwise, the data packet is dropped. According to the invention, through the probability of occurrence of the each multicast group, the number of the hash functions used in the each kind of the multicast group in the multicast forwarding table is calculated so that different kinds of the multicast groups can use different hash functions. A false alarm rate of the data center is reduced so that a bandwidth waste ratio is decreased as a whole.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a data center scalable multicast method and system. Background technique [0002] Cloud computing is favored because of its safety, reliability, convenience, and almost infinite variety of possible applications. It is one of the foreseeable inevitable trends in the development of the Internet. Among the many technical fields involved in cloud computing, the data center is its core and the key basic platform of cloud computing. In the process of rapid implementation and development of cloud computing, if we want to be more competitive in the market and occupy a larger market share, we must provide users with better services, which requires efficient, reliable, and low-cost data centers. for support. [0003] As an important part of cloud computing services, data centers have been undergoing development and transformation. The power supply and heat dissipation requirements ...
