Embodiment 1

[0052] In this embodiment, the communication control frame is a multicast invitation frame, the data transmission channel is a multicast channel, and the receiving node is a computer node participating in multicast communication except the sending node. Nodes are specified in the multicast invite frame. There is one conference channel and three multicast channels, which are multicast channel 1, multicast channel 2 and multicast channel 3 respectively. see Figure 4 , the wireless multicast communication method of the computer cluster system of the present embodiment includes:

[0053] Step S41, the sending node acquires a channel token of the multicast channel on the conference channel, and the channel token is used to confirm that the sending node occupies the multicast channel.

[0054] Step S42, the sending node sends a multicast invitation frame on the conference channel, and the multicast invitation frame includes the identifier of the broadcast channel for transmitting...

Embodiment 2

[0072] In this embodiment, the communication control frame is a point-to-point invitation frame, the data transmission channel is a point-to-point channel, and the receiving node is another computer node participating in point-to-point communication except the sending node. Points are specified in point-to-point invite frames. There is one conference channel and five point-to-point channels, which are point-to-point channel 1, point-to-point channel 2, point-to-point channel 3, point-to-point channel 4 and point-to-point channel 5. see Image 6 , the wireless point-to-point communication method of the computer cluster system of the present embodiment includes:

[0073]In step S61, the sending node acquires a channel token of the peer-to-peer channel on the conference channel, and the channel token is used to confirm that the sending node occupies the peer-to-peer channel.

[0074] Step S62, the sending node sends a point-to-point invitation frame on the conference channel, a...

Abstract

The invention discloses a wireless multicast and point-to-point communication method for a computer cluster system, which comprises the following steps: sending a communication control frame on a session channel by a sending node, wherein the communication control frame comprises an identification of a data transmission channel for transmitting a data frame and an identification of a receiving node; distributing the session channel and the data transmission channel on the basis of a frequency range of a wireless radio-frequency signal transmitted by an antenna unit; sending a confirming frame by the receiving node after the communication control frame is received by the session channel; switching to the data transmission channel for sending the data frame by the sending node after the confirming frame of the received node is received by the session channel; and switching to the data transmission channel and receiving the data frame sent by the sending node by the receiving node. According to the wireless multicast and point-to-point communication method provided by the embodiment of the invention, the flexibility of the communication between computer nodes in wireless connection is increased and the high throughput of the communication between the computer nodes is kept.

Description

technical field [0001] The invention relates to computer technology, in particular to a wireless multicast and point-to-point communication method of a computer cluster system. Background technique [0002] A computer cluster or massively parallel computer is a common form of high-performance computer architecture, which is composed of multiple computer nodes, and each computer node is composed of one or more circuit boards (host unit). Multiple computer nodes are installed in a closed chassis or cabinet to form a computer cluster system. The data communication and exchange between various computer nodes are realized by the interconnection network, among which, the common forms of the interconnection network are: electric wire, optical fiber, optical waveguide, free space laser, radio frequency waveguide interconnection and so on. [0003] Some information about the large-scale parallel computer structure and its interconnection network can also refer to the Chinese inventi...
