An apparatus for managing requests for media data such as video data for effecting rapid channel change in IPTV services comprises an interface for receiving data requests addressed for processing by a particular data request service device, and an agent operatively coupled to the interface and configured for selecting which of a number of different data request service devices to send the request, irrespective of the device to which the request is addressed. The apparatus includes a module for determining if a received request can be serviced by a preferred request service device based on its monitored ability to service the request. If the module determines that the preferred device is capable of servicing the request, the request is directed to that device, and otherwise to another device, which may be the device to which the data request is originally addressed.; The preferred request service device may reside at an access node for delivering media services to subscriber equipment.

The present invention provides a message transmission method and device. The method comprises: an SDN controller sends a first flow table to a first virtual switch, when the first virtual switch receives a message sent by a first virtual machine to a second virtual machine, the first virtual switch sends the message to a virtual router through a VXLAN tunnel built between the virtual router and the first virtual switch; when the SDN controller receives the message sent by the first virtual machine to the second virtual machine, a second virtual switch corresponding to the second virtual machine is obtained, and a second flow table and a third flow table are generated; the SDN controller sends the second flow table to the virtual router, and when the virtual router receives a message, the virtual router sends the message to the second virtual switch through a VXLAN tunnel built between the virtual router and the second virtual switch; and the SDN controller sends the third flow table to the second virtual switch, and when the second virtual switch receives a message, the second virtual switch sends the message to the second virtual machine. The problems of time delay, packet loss and the like of business access may be avoided.

An information center network architecture method for manned deep space exploration. According to the space area and node communication range, according to the connection plan, the aggregation node in each domain can be selected as the domain server of the domain. It is responsible for internal information management in the domain and external Responsible for building inter-domain transmission links to realize cross-domain data transmission; through this domain server, each domain forms a top-level domain topology network for networking communication, and data and information are synchronized and transmitted between these top-level domains; each The data transmission and network management in the top-level domain are realized through the concept of hierarchical domains; according to the longitude, latitude and altitude geographic information spatial position, the top-level domain or domain space is subdivided into multiple second-level domains, and each second-level domain also has a domain Servers, all domain servers are interconnected to form the backbone transmission network of the entire network and tree-like network topology management, which solves the problems of flexible networking and delay tolerance between domains for manned deep space exploration in the future.

A Network Reporting Entity (NRE) and a User Equipment (UE) as well as a respective method therein for use in a wireless communication network for enabling controlling data transfer between the UE and a network cache are provided. The NRE receives, from the UE, a request to start reporting network status and transmits, to the UE, information regarding the status of the network, the information pertaining to whether network condition is in a state where a data transfer is preferred or not, wherein the NRE obtains the information regarding the status of the network from the Network Conditions Information Entity (NCIE). In this manner, the UE is enabled to control the data transfer between the UE and the network cache.

Described embodiments provide a digital unit for controlling a plurality of radio units to transmit a signal to user equipment. The digital unit may determine whether user equipment is located at an overlapping service area of a first radio unit and a second radio unit and control the first radio unit to transmit a signal to the user equipment using the first antenna and control the second radio unit to transmit the same signal to the user equipment using the second antenna when the user equipment is located in the overlapping service area. A transmission pattern of the first antenna of the first radio unit may be different from a transmission pattern of the second antenna of the second radio unit.

The invention provides a video processing method and apparatus, wherein the method comprises: employing a CDN (Content Delivery Network) service node to receive a video source file, coding the video source file, obtaining a coded video file, and providing the video file to first user equipment through a CDN upper layer node of the CDN service node. The video processing method and apparatus solve the problems in related technologies caused when a client needs to receive a video source file by himself / herself, and codes and stores the video source file, reduce requirements for market access of the video website industry, lighten a flow load of a client source station, reduce storage resources of the client source station, and accelerate an uploading speed of netizens.

A video resource sharing method based on the similarity of vehicle movement behavior in the Internet of Vehicles, S1, calculate the road flow based on the historical traffic data of the road, and use the road flow of the corresponding time interval to represent the time cost of passing the road; S2, use the length of the road to represent the passing time The distance cost of the road; S3, convert the distance cost into a weight value and then combine it with the time cost to calculate the road driving cost, and obtain the driving mode between any starting point and any end point through the road driving cost; S4, vehicle-based driving mode Calculate the duration of the similar movement behavior between the vehicles; S5. If the similar duration of the movement behavior between the two vehicles is longer than the video sharing duration required to transmit the video resource, transmit the video resource between the two vehicles. The present invention judges whether the sharing of video resources between vehicles is suitable by accurately describing the similarity of the moving behavior of the vehicles, which can ensure the stability of the video resource sharing process and improve user experience.

A method for determining information about a length of a timeout period, which represents a length of time without communication after which a device of a first type becomes unreachable. Information about the timings of successful and unsuccessful message sent to the device(s) of a first type is obtained, alongside information about the timings of messages sent by the device(s) of the first type, and used to calculate the length of a timeout period.

The invention discloses an intelligent holographic targeted public transportation system and an achieving method thereof. The system and the method mainly solve the problem that the traffic burden is increased due to the low punctuality rate, the low comfort level, the low convenience and the long driving time of buses caused by the lack of a complete vehicle scheduling system in the prior art. The intelligent holographic targeted public transportation system comprises an information collection platform, a data processing center, a vehicle scheduling platform and a user terminal, wherein the information collection platform is used for collecting user riding information, vehicle driving line information is stored inside the data processing center, the data processing center is connected with information collection platform through a network and processes the collected information, the vehicle scheduling platform exchanges information with the data processing center through the network, and the user terminal exchanges information with the vehicle scheduling platform and the data processing center through communication or the network. According to the scheme, by the aid of the system and the method, the utilization ratio of public transportation vehicles is fully guaranteed, so that the traffic burden and operating costs of vehicles are effectively reduced, and the system and the method is high in practical value and popularization value.
