Abstract: A method, a system, and a device for switching a service unit are provided. The method includes: determining a target service unit; and triggering the target service unit to publish first routing information according to configuration information of a first service unit for a first load balancing task, so as to replace the first service unit to provide a traffic distribution service for the first load balancing task. When the entire service network needs to perform disaster tolerance switching and capacity dispatching, the method provided in the embodiments of this application can effectively improve the real-time performance of traffic switching, and avoid the problem of relatively poor real-time performance of traffic switching caused by the influence of DNS cache in the existing technologies.

Abstract: Embodiments herein describe a CDN where anycast routing is used to identify a load balancer for selecting a cache in the CDN to use to deliver a requested object to a user. In one embodiment, the user performs a DNS lookup to identify an anycast IP address for a plurality of load balancers in the CDN. The user can then initiate anycast routing using the anycast IP address to automatically identify a load balancer. Once the identified balancer selects the cache, the load balancer can close the anycast connection with the user device and use a redirect to provide the user device with a unicast path to the selected cache. The user device can then establish a unicast connection with the cache to retrieve (e.g., stream) the object.

Abstract: Methods for operating a device and for managing bootstrapping of devices are disclosed. The method (100) for operating a device comprises computing (102) a derivative of a secret shared between the device and a server entity of a network, generating (104) a temporary bootstrap URI by combining at least a part of the computed derivative with a static bootstrap URI for the network, and sending (106) a bootstrap request to the temporary bootstrap URI. The method for managing bootstrapping of devices comprises generating temporary bootstrap URIs corresponding to devices operable to connect to a network, and updating a network DNS registry to map the generated temporary bootstrap URIs to the IP address of at least one of a bootstrap server instance reachable via the network and/or a bootstrap load balancer. Also disclosed are a device, a bootstrap load balancer, a bootstrap server, and a computer program.

Abstract: A technique to stop lateral movement of ransomware between endpoints in a VLAN is disclosed. A security appliance is set as the default gateway for intra-LAN communication by overwriting the DHCP responses. A high availability cluster of the gateways is utilized to distribute traffic and implement load balancing amongst the gateways.

Abstract: A method and system for implementing domain name services (DNS) is described. In one aspect a query from a user device for access to a particular resource record may be received and forwarded to an authoritative DNS device. A reply to the query may be received from the authoritative DNS device. Information of the reply also may be distributed to other DNS devices.

Abstract: One embodiment of the present invention provides a system that can manage access to a service from a cluster of computing nodes. An instance of the system can operate on a respective computing node. During operation, the system instance can identify an Internet Protocol (IP) address, which provides access to the service from the cluster of computing nodes to a client device at a client site. The system instance can select the computing node for hosting the IP address in the cluster of computing nodes based on a set of selection criteria. The selection is performed independently at the computing node. The system instance can then assign the IP address to the computing node. The assignment allows a request for the service to be directed to the computing node. Subsequently, the system instance can facilitate the service from the cluster of computing nodes based on the request.

Abstract: The present disclosure relates to managing services by a managed service provider (MSP) in a cloud based infrastructure. A control plane of the MSP is established in a first tenancy, and a first access plane of the MSP is established in a second tenancy of a cloud environment. The control plane is configured to manage a plurality of services offered by the MSP to a first host machine included in the second tenancy. A first request is transmitted from the control plane to the first access plane, where the first request is forwarded by the first access plane to the first host machine, and corresponds to a service utilized by the first host machine and managed by the control plane of the MSP. In response to the first request being validated, a first state of the first host machine is modified in the second tenancy based on the first request.

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: 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
