The present invention discloses a network security HTTP negotiation method and related devices. the method comprises: a server receiving an HTTP request message with a header field sent by a terminal, wherein the header field indicates security mechanism(s) supported by the terminal, or the security mechanism(s) supported by the terminal and indication parameter(s) which show that the terminal has been in an accessing safety state; the server parsing the HTTP request message, and sending a response message with negotiated security mechanism(s) supported by the server and priority parameter(s) thereof to the terminal according to the result of the parsing if the header field of the request message indicates the security mechanism(s) supported by the terminal; and the server receiving another HTTP request message sent by the terminal again to authenticate security mechanism(s) selected by the terminal, wherein the header field of the request message indicates the security mechanism(s) selected by the terminal according to the response message and the priority parameter(s) of the security mechanism(s). The invention expands the HTTP protocol, solves the problem that the terminal security mechanisms are difficult to be deployed, and improves the network service quality.

The invention discloses a method and a device for analysis of network service quality. The method includes: building a network service quality evaluation model of a network system in a network management system in advance, and further configuring resources needing to be monitored in the evaluation model; obtaining scores and grades of the network service quality by periodically acquiring performance data of the resources configured in the evaluation model and according to computation rules defined in the evaluation model; and generating a network service quality report and sending warning messages according to preset policy rules, so that network management staff can purposefully improve network configuration, and network service quality requirements are met.

The present invention provides a single-interface multi-channel switching method for a vehicle-mounted ad hoc network. The nodes are divided into three working modes of α, β and γ according to the node density and service information flow. According to the characteristics of different working modes, different data transmission methods are adopted. mode, under the condition of ensuring the reliable transmission of safety information, the service channel is dynamically allocated, the number of channel switching is reduced as much as possible, and the utilization rate of the service channel is improved.

The invention discloses a method for reducing communication loads and the energy consumption of a data center. The method includes enabling a dispatching center to compute an initial placement sequence of virtual machines according to an expenditure matrix and a service demand matrix; configuring service communication data to corresponding switchboards and links according to bandwidth constraint conditions and acquiring an initial service routing information table; judging whether an execution communication duration of a task carried by a current virtual machine exceeds a communication duration threshold value or not, and migrating the current virtual machine into a target physical machine logically closest to a target virtual machine if the execution communication duration of the task carried by the current virtual machine exceeds the communication duration threshold value; enabling the dispatching center to judge whether all the virtual machines carried with tasks with execution communication durations exceeding the communication duration threshold value are migrated or not, enabling the dispatching center to update the initial placement sequence of the virtual machines and the initial service routing information table if all the virtual machines carried with the tasks with the execution communication durations exceeding the communication duration threshold value are migrated, and closing the switchboards which are not used by the data center. The method has the advantages that network information dynamic perception and feedback regulation functions can be realized, services with the communication durations exceeding the duration threshold value are reasonably distributed, the usage amount of the switchboards is reduced, and the purpose of saving energy for the data center is achieved.

The invention discloses a method for uniquely identifying user equipment, comprising: collecting user equipment information including a plurality of equipment attributes generated when user equipment accesses network services, and associating and storing each user equipment information with a corresponding user equipment identifier It is a record in the sample library; compare every two pieces of user equipment information in the sample library, and calculate the standard likelihood of the same and different attributes of each equipment when the user equipment identifiers are the same; obtain the two user equipment to be identified Device information, compare each device attribute of the two pieces of device information, obtain the standard likelihood corresponding to each device attribute according to the comparison result, and multiply all the standard likelihoods to obtain that the two user device information belong to the same user device The predicted probability; by comparing the predicted probability with a probability threshold to identify whether the two pieces of user equipment information belong to the same user equipment. The invention also discloses a device for identifying the uniqueness of the corresponding user equipment and a computing device.
