Abstract: Disclosed is a network management system that provides an interface to enable diagnostics and troubleshoot of a remotely managed multi-site network. Some embodiments provide a natural language interface, while other embodiments provide a chatbot type interface that communicates with a technician via traditional text information on a display screen. The diagnostic and troubleshooting capabilities search a central data store that receives device property information from each site of the multi-site network. Based on devices or users that match portions of the entity, queries to the data store are initiated to obtain additional data on the devices. A response to the query is then provided based on the properties of the devices.

Abstract: A method for controlling a ratio of multi-CNAME traffic, includes: receiving, by a target authoritative DNS server, an A record query request for a target domain name sent by a local DNS server, and determining, by the target authoritative DNS server, all CNAME domain names according to stored CNAME records of the target domain name; acquiring, by the target authoritative DNS server, IP addresses corresponding to each CNAME domain name of all the CNAME domain names from an authoritative DNS server corresponding to each CNAME domain name; combining, by the target authoritative DNS server, IP addresses corresponding to all the CNAME domain names according to a preset traffic pulling ratio of the target domain name, to generate at least one IP group; and randomly feeding back, by the target authoritative DNS server, one IP group of the at least one IP group to the local DNS server.

Abstract: Disclosed are embodiments for automatically resolving faults in a complex network system. Some embodiments monitor one or more of system operational parameter values and message exchanges between network components. A machine learning model detects a fault in the complex network system, and an action is selected based on a cause of the fault. After the action is applied to the complex network system, additional monitoring is performed to either determine the fault has been resolved or additional actions are to be applied to further resolve the fault.

Abstract: Various aspects of the subject technology relate to systems, methods, and machine-readable media for a learning platform that employs machine learning to identify patterns that describe meaningful subgroups of patients associated with a particular disease, distinct characteristics of each subgroup, and implications of belonging to a specific subgroup in terms of developing into a more severe disease state for patient journey mapping. The system may include a mapping server that includes a medical-event embedding engine that embeds electronic health records into vectors, a clustering engine that identifies clusters of patients with similar patient journeys by operating on the output of the medical-event embedding engine, and a cluster profiling engine that identifies distinguishing medical events for each identified cluster by operating on the output of the clustering engine.

Abstract: The present disclosure provides an DNS server and configuration loading method, an DNS network system, and a domain name resolution method and system. The present disclosure relates to the field of network communication technologies. The DNS server configuration loading method includes: dividing at least two NS partitions according to network carriers and/or regions; based on an IP address of an DNS server, obtaining an NS partition on which the DNS server has a traffic; from local records or database, filtering out domain name configuration information belonging to the NS partition corresponding to the DNS server; and loading the filtered-out domain name configuration information into a memory of the DNS server. The present disclosure significantly reduces the amount of DNS configuration; increases the efficiency for the DNS server to load the domain name configuration information; reduces the loading time; and reduces the memory resource consumption of the DNS server.

Abstract: The present disclosure provides a DNS network system, and a domain-name parsing method and system. A local DNS server receives a domain-name parsing request from a client terminal a network operator in the same network and sends the domain-name parsing request to a root server; based on an NS record of an upper-level authoritative DNS server returned by the root server, sends the domain-name parsing request to the upper-level authoritative DNS server; based on an NS record of an external authorized server returned by the upper-level authoritative DNS server, sends the domain-name parsing request to the external authorized server; based on an A-record of a lower-level authoritative DNS server returned by the external authorized server, sends the domain-name parsing request to the lower-level authoritative DNS server and receives a domain-name parsing result sent by the lower-level authoritative DNS server.

Abstract: A domain name resolution system, a domain name resolution server, and a domain name resolution method are provided. The domain name resolution method comprises following steps: configuring a same extensive domain name for portal domain names using a same server group; resolving a domain name requested by the client to a portal domain name via a CNAME; performing resolving on the portal domain name, and using a resolution result as the resolution result of the domain name requested by the client to be sent back to the client.
