The invention discloses a cloud rendering network deployment subsystem, which includes a proxy server, the proxy server is connected to an external network, and the proxy server is respectively connected to at least one virtual machine; the proxy server includes a control information processing unit, a data information processing The control information processing unit is configured to receive the control information sent by the external network, analyze the control information, convert the control information into information encapsulated by the TCP protocol, and send the information encapsulated by the TCP protocol to In the corresponding virtual machine; the data information processing unit is configured to receive the data information sent by the virtual machine, convert the data information into a protocol encapsulation form corresponding to the external network, and encapsulate the corresponding protocol The form is sent to the external network. Through the above adaptation, the present invention can support data transmission between multiple network protocols, facilitate different clients to access the cloud server, and provide better user experience.

The invention discloses a resource configuration method and system and a relevant device. A base station sends virtual bandwidth configuration information to a terminal through high-level configuration signalling, the virtual bandwidth configuration information indicates X virtual bandwidths corresponding to the terminal or indicates whether the virtual bandwidths are adopted or not, the system bandwidth of the terminal is divided into N sub-bandwidths, one virtual bandwidth corresponding to the terminal is composed of K sub-bandwidths, K, N and X are all positive integers larger than or equal to one, and K<N. The virtual bandwidths are configured, signalling cost in small cells can be lowered, interference cooperation between the small cells is supported, data transmission of the small cells is supported well under the condition of being compatible with an existing system and guaranteeing consistency of transmission and feedback, and frequency efficiency of the system is improved.

The invention relates to an self-adaptive communications method for double-clustering wireless sensor network, which comprises the following steps: M, the communications inside the cluster, the cluster members send the data to a cluster head; N, the communications between the clusters, namely the communications between the cluster heads; when two cluster heads are positioned at the same virtue cluster, the two cluster heads implement data interaction at the communications time of period between the clusters; when the two cluster heads are positioned at different virtue clusters, the two cluster heads implement data interaction at the self-adaptive communications time of period between virtual clusters; a cluster head node at the common boundary of the two virtual clusters needs an self-adaptive communications time of period between the virtues clusters in a superframe cycle; depending on relevant starting and ending time of the communications time of period of the opposite clusters, the time of period of self-adaptive communications is set at a corresponding position in the superframe cycle of the cluster head. The invention enables better support for the data transmission in the network, and has good energy efficiency and the expansion of the network scale; and has poor requirement for the clock synchronous requirement of node, thereby the invention is suitable for design in the MAC layer of the sensor network node with limited resource.

The disclosed structure of frame as length variable data frame includes frame head and payload. Frame head defines variety of length. Using the said structure of frame makes protocol in high layer possible to support data transmission with addressing requirement between master device and slave devices. Using scheme of sub frame heads in the structure of frame makes protocol in high layer possibleto support communication in full duplex or half-duplex modes between master device and slave devices in high efficiency. In time of transferring low volume data, the method uses short head in structureof frame with variable length in order to raise transmission efficiency.

The invention discloses a communication method suitable for data transmission on a serial peripheral device interface bus: a variable-length data frame is defined, including a frame header and a payload, and the change of the length is defined by the frame header; the master device and the slave The synchronous transmission mode is adopted between the devices; all transmissions are initiated by the master device, and the frame header of the data frame is always sent from the master device to the slave device. The method of the present invention can support data transmission with addressing requirements between the master device and the slave device; by adopting a subframe header and a variable-length frame structure scheme in the frame structure of the method of the present invention, the method can Efficiently support full-duplex or half-duplex communication between the master device and the slave device, and improve transmission efficiency; in the communication method of the present invention, a joint synchronization scheme combining self-synchronization and forced synchronization is adopted to ensure reliable The performance and the burden of the main equipment can achieve the best results.
