Methods, apparatuses and systems facilitating the aggregation or bonding of communications paths into a higher-bandwidth, logical communications path. Embodiments of the present invention can be applied to bond different physical links (e.g., xDSL over twisted pairs), different channels on the same physical line, or even different channels or frequencies in a wireless communications network. The present invention further provides methods, apparatuses and systems facilitating the re-sequencing of data flows transmitted across bonded communications paths. In one embodiment, the re-sequencing methodology of the present invention adapts to the transmission delays (both absolute and relative) across the bonded communications path.

The embodiment of the invention discloses a resource allocation method, network side equipment and a terminal. The method comprises the following steps: enabling the network side equipment to allocate uplink resources of a low-latency service through a configuration or reservation mode; and generating uplink scheduling information based on the allocated uplink resources, and sending the uplink scheduling information.

The invention discloses a resource reservation method and device and a resource allocation method and device. The resource reservation method comprises the steps that: a terminal receives configuration information from a network side; and the terminal sends control indication information which comprises at least one piece of information in resource occupation indication information and resource reservation indication information, the resource occupation indication information is used for indicating a reserved resource when the terminal does not need to send data, and the resource reservation indication information is used for indicating a reserved resource when the terminal does not need to send data. According to the resource reservation method and device and the resource allocation method and device, the terminal can timely select a suitable resource when an emergency occurs, and the problems of constantly retransmitting and correcting due to resource collision when the emergency occurs can be avoided.

The invention relates to the technical field of industrial Internet identifier analysis and networks, in particular to a novel caching method and system for an industrial Internet identifier analysisrecursive server. An original caching method of the recursive server is not changed, and the identifier and the information with higher query frequency can be dynamically adjusted to the caching queueuntil the identifier is deleted due to expiration of TTL or discarded due to the fact that the caching queue reaches the upper limit of the length. Meanwhile, a newly-built secondary node cache queueis used for caching IP address information corresponding to the secondary node, so whether the secondary node cache queue has a secondary node address or not can be checked if the recursive server has no cache locally, and if the secondary node cache queue has the secondary node address, a request is directly initiated to the secondary node to obtain corresponding identification information, so that interaction operation with a top-level node is reduced, thereby reducing the top-level node pressure and bandwidth load. According to the method, the frequency of frequently interacting with the top-level node can be reduced, and the working efficiency of industrial Internet identifier analysis caching can be improved.

The invention discloses a method for providing resource configuration and access point selection strategies for multi-access edge computing. The method includes an initial allocation method and an incremental allocation method. The initial allocation method is used to jointly allocate resources in a wireless access point and an edge server from a global perspective to efficiently provide VNF-FGs.The incremental allocation method is used to quickly adjust AP (access) node selection strategies and system resource reallocation of each Internet of things equipment to cope with the variability ofInternet of Things equipment requests. According to the scheme of the invention, the optimal VNF (virtual network function) deployment position and the wireless access point accessed to the multi-access edge computing can be obtained under the dynamic workload, so that the low delay requirements of Internet of things services can be met, and meanwhile, the overall operating cost required in a timeperiod can be minimized.

Embodiments of the invention provide an information transmission method and equipment. The method comprises the following steps that network equipment determines time slot format information, whereinthe time slot format information is used for indicating a position of an uplink symbol, a position of a downlink symbol and a position of an unknown symbol in a time slot; the network equipment sendsthe time slot format information, and the terminal equipment receives the time slot format information from the network equipment, wherein the time slot format information is used for indicating the position of the uplink symbol, the position of the downlink symbol and the position of the unknown symbol in the time slot; and the terminal equipment determines a time slot format according to the time slot format information. An uplink and downlink ratio provided by the information transmission method and equipment can be applied to the requirements of scenes with low time delay and high reliability.

The invention discloses a cloud platform failure recovery method and system. The cloud platform failure recovery method includes the steps that fault detection is carried out on a server through task execution time and magnetic disk read-write speed, the server failure rate of the system is calculated through the result of fault detection, if the server failure rate is smaller than a preset threshold value, the server is recovered automatically, otherwise, the server is prohibited from automatic recovery. By means of the cloud platform failure recovery method and system, due to the facts that hardware failures are detected based on the macro phenomenon and effective strategies of automatic failure recovery are carried out, the macroscopic hardware reliability of a cloud platform is guaranteed, and the problems related to hardware are prevented from exerting adverse effects on user experience.
