Abstract: Some embodiments provide a novel method of performing health monitoring for resources associated with a global server load balancing (GSLB) system. This system is implemented by several domain name system (DNS) servers that perform DNS services for resources located at several geographically separate sites. The method identifies several different groupings of the resources. It then assigns the health monitoring of the different resource groups to different DNS servers. The method then configures each particular DNS server (1) to send health monitoring messages to the particular group of resources assigned to the particular DNS server, (2) to generate data by analyzing responses to the sent health monitoring messages, and (3) to distribute the generated data to the other DNS servers. The method in some embodiments is performed by a set of one or more controllers.

Abstract: The invention is based, in part, on a system and method designed to be able to easily and automatically scale up to millions of cameras and users. To do this, this discourse teaches use of modern cloud computing technology, including automated service provisioning, automated virtual machine migration services, RESTful API, and various firewall traversing methods to facilitate the scaling process. Moreover, the system and method described herein teaches scalable cloud solutions providing for higher though-put camera provisioning and event recognition. The network may segregate the retrieval server from the storage server, and by doing so, minimizing the load on any one server and improving network efficiency and scalability.

Abstract: Systems, apparatuses, and methods are described for adjusting capacity in a networking environment. A networking system comprising clients, servers, load balancers, and/or other devices may expand and contract network capacity as needed. When expanding network capacity, load balancers may instruct client devices to connect to servers that are part of the expanded network. When network capacity is reduced, a server and/or a load balancer my instruct client devices to close a connection with a first server and establish a connection with a second server. Client devices may seamlessly begin using the connection with a second server without having to wait for a connection timeout with the first server.

Abstract: An acquisition unit acquires a state of a server including pieces of virtual CPE, and an instructing unit instructs CPE connected to the virtual CPE to control a communication band based on the state of the server. The instructing unit instructs the CPE to limit a communication band to a predetermined value or less based on a CPU usage rate acquired by the acquisition unit exceeding a predetermined threshold value. The instructing unit instructs the CPE to limit a communication band to a predetermined value or less in based on the number of connections of the CPE acquired by the acquisition unit being less than a predetermined threshold value. The acquisition unit acquires presence or absence of CPE not connected to the virtual CPE, and the instructing unit instructs the CPE to block communication based on the presence of CPE not connected to the virtual CPE.

Abstract: A system for adjusting individual host rate limits based on a fleet-wide service rate limit and a fleet host count. The system includes a fleet of hosts for a service. Individual hosts of the fleet of hosts respectively include application logic, a host rate limiter to limit interactions between the application logic and another service according to a host rate limit for the individual host, and an adaptive rate component. The adaptive rate component updates a host entry in a host table to indicate a current heartbeat timestamp for the individual host. The adaptive rate component retrieves the fleet-wide service rate value and the fleet host count value. The adaptive rate component determines the host rate limit for the individual host based on the fleet-wide service rate value and the fleet host count value. The adaptive rate component provides the host rate limit to the host rate limiter.

Abstract: Disclosed herein are an apparatus and method for autoscaling a service shared in a cloud. The apparatus may include memory in which at least one program is recorded and a processor for executing the program, and the program may perform autoscaling by which at least one second service for performing the same function as a first service is additionally generated or deleted depending on a load that is incurred when multiple clients call the first service in the cloud. The at least one second service may be set to one of two or more execution types having different response times depending on a response time required by each of the multiple clients.

Abstract: A load-balancing cluster includes a switch having a plurality of ports; and a plurality of servers connected to at least some of the plurality of ports of the switch. Each server is addressable by the same virtual Internet Protocol (VIP) address. Each server in the cluster has a mechanism constructed and adapted to respond to connection requests at the VIP by selecting one of the plurality of servers to handle that connection, wherein the selecting is based, at least in part, on a given function of information used to request the connection; and a firewall mechanism constructed and adapted to accept all requests for the VIP address for a particular connection only on the server that has been selected to handle that particular connection. The selected server determines whether it is responsible for the request and may hand it off to another cluster member.

Abstract: A Domain Name System (DNS) resolver node receives a first DNS query from a first client device. The resolver node determines that it cannot answer the query using its local cache so it performs a recursive query to obtain the answer. The answer is sent to the first client and stored in its local cache. The resolver node further transmits the answer to multiple other resolver nodes that are part of the same cluster so they can update their respective local cache with the information. Upon receiving a message from another resolver node that includes a set of resource record(s) not in its local cache, the resolver node stores that set of resource record(s) in its local cache so that it can locally answer subsequent requests for those resource record(s) locally.
