Disclosed in the present invention is a beam coherence eliminating element. The optical medium material of the element comprises microcrystalline glass, wherein microcrystalline particles therein have a size of 0.1-1000 nm and are distributed randomly. As the crystals in the microcrystalline glass can change the phase of light beams, the microcrystalline glass can change the phase of the light beams randomly, thereby eliminating the coherence of the beams. The crystal size of the microcrystalline glass is small, and thus does not affect the transmission efficiency of light beams. The element of the present invention has a simple structure and is convenient to use, and can be added in the process of beam transmission to easily eliminate beam coherence.

A software-defined data center, and a deployment method for a service cluster are described therein. An SDN controller manages a cluster by using a shared IP address. The SDN controller obtains an online virtual machine event that is sent by an edge switch accessed by a new online virtual machine; obtains a MAC address of the new online virtual machine, and identifies the new online virtual machine; then identifies whether an IP address of the new online virtual machine is a shared IP address; and if the IP address of the new online virtual machine is the shared IP address, deploys the new online virtual machine to a service cluster corresponding to the shared IP address. The SDN controller automatically completes creation, capacity expansion of the service cluster, so that no manual intervention from a tenant is required, and tenant experience is good.

A software-defined data center (SDDC) and a service cluster scheduling and traffic monitoring method therefor. A software defined networking (SDN) controller implements a scheduling and decision function of load balancing. As a load balancer, the SDN controller follows a serving node load balancing principle, and customizes a packet forwarding flow table to instruct an edge switch to direct user traffic to a specified serving node. The SDN controller may monitor load of a serving node in a service cluster, execute a load balancing function of the load balancer according to a load monitoring result, and select a target virtual machine. Using the SDN controller as a load balancer, a dynamic expansion capability of the SDN may be multiplexed at a control layer, and a network resource of the SDN network may be multiplexed at a network forwarding layer. Implementation complexity is low, and investment costs are low.

The invention provides a compliance detecting method of payment applications in a virtualized environment, and pertains to the field of security technology of payment applications. The detecting method is used for compliance detection for PCI DSS isolation demands. The detecting method can determine whether it is a compliance state by analyzing the current virtual machine domain and its connection from data stream, and can also determine whether it is a compliance state by analyzing the purity of network flow of virtual machines. The detecting method is suitable for a virtualized environment and makes the detection of compliance accurate in the virtualized environment, thus being advantageous for guaranteeing the security of payment applications.

An allocation instruction is received that includes a target data operand and a storage medium operand indicating a storage medium for storing the target data. A data dependency is identified that specifies metadata that includes access control information specifying which users have permission to perform a write operation to the file that includes the target data. In response to determining that the allocation instruction allocates the target data from a first storage medium to a second storage medium having a faster data IO rate, the allocation instruction is modified to also allocate the metadata specified in the data dependency to the second storage medium. In another aspect, the allocation instruction is modified to also allocate the metadata identified in the data dependencies to one or more storage mediums with data IO rates that are at least as fast as the second storage medium.

K classifiers and S network service processors are deployed in a network device. A network adapter receiving queue is divided into multiple queue areas. Each classifier may acquire a packet identifier from a queue area that corresponds to the classifier and is in the network adapter receiving queue, that is, the network adapter receiving queue has multiple information reading interfaces such that the K classifiers may concurrently read packet identifiers from corresponding queue areas in the network adapter receiving queue, and the K classifiers may further concurrently determine, based on the packet identifiers acquired by the K classifiers, corresponding flow queue identifiers. Related operations before the K classifiers distribute packet description information to flow queues may all be concurrently executed, and concurrent execution makes processing times of the related operations become partially or completely overlapped.

In a network system including a mirror switch, a distribution device and a plurality of recording devices, a method for recording multimedia data is provided. The mirror switch sends communication data to the distribution device and the plurality of recording devices. The distribution device obtains multimedia data identification information from a signaling message included in the communication data, generates a recording instruction which includes the multimedia data identification information, and sends the recording instruction to the recording device to instruct the recording device to record the multimedia data.

A mechanism is provided for balancing workload to one or more storage disks in a plurality of storage disks during redistribution or replication associated with adding or removing a storage disk to the plurality of storage disks. Historical information in collected information from the plurality of storage disks is analyzed to identify I/O operation patterns on a per storage disk level. An average amount of I/O operations that occur within each storage disk for a given time period are identified. For each storage disk that is impacted, a disk on/off-hoarding plan is generated that identifies a subset of I/O operations from a set of I/O operations to execute in the given time period using the average amount of I/O operations that historically occur within the storage disk that is impacted during the given time period. The subset of I/O operations are then executed in the given time period.

Techniques are described for determining whether a stream is in a stable state and permitting adjustment of the PTS value when the stream is in a stable state. The stream can be in a stable state when PTS values received over a period of time do not change unexpectedly. For example, when the stream is in a stable state, the PTS value for audio or video can be adjusted based on system buffer levels, i.e., over flow or under flow. The amount of adjustment of the PTS value can be based on whether the buffer level appears to be moving into greater overflow or underflow. In some cases, when the stream is not in a stable state, the audio is permitted to be played back at a sample rate and video is permitted to be played back at a frame rate instead of being controlled by PTS.

Techniques for synchronization of audio and video

An allocation instruction is received that includes a target data operand and a storage medium operand indicating a storage medium for storing the target data. A data dependency is identified that specifies peripheral data on which the target data depends. In response to determining that the allocation instruction will cause the target data and the peripheral data to locate to different storage mediums having different data IO rates, the execution of the allocation instruction is prevented. In another embodiment, in response to determining that the allocation instruction allocates the target data from a first storage medium to a second storage medium having a faster data IO rate, the allocation instruction is modified to also allocate the peripheral data specified in the data dependency to the second storage medium.
