Abstract: Embodiments of the present disclosure provide a universal session persistence method for different communications protocol layers. The method includes: generating, by a first node device, a first interaction message, where the first interaction message includes a first load balancing protocol header, the first load balancing protocol header is independent of a protocol header corresponding to a communications protocol layer at which the first interaction message is generated, the first load balancing protocol header includes a first destination end load balancing index, and the first destination end load balancing index is used to identify a second node device that is to receive the first interaction message; and sending, by the first node device, the first interaction message to the second node device via a first load balancer.

Abstract: Domain Name System (DNS) records of a single site are analyzed. A first one of the DNS records points to an IP address of a service. A second one of the DNS records is not pointed to an IP address of the service and is referencing the first DNS record. An electronic communication is transmitted to an operator for the single site that includes a notification that an IP address of the single site is exposed through the second DNS record.

Abstract: A mechanism controls global synchronization, or registration floods, that may result when a large number of endpoints in a Voice over Internet Protocol (VoIP) network such as an Internet Protocol Multimedia Subsystem (IMS) come online simultaneously after a catastrophic failure. The mechanism allows the Domain Name System (DNS) infrastructure to efficiently control the overload condition by registering user end points with backup border elements, and by staggering and by randomizing the time-to-live (TTL) parameter in registrations with backup border elements.

Abstract: The disclosure herein describes a system for providing distributed global server load balancing (GSLB) over resources across multiple data centers. The system includes a directory group comprising one or more directory nodes and a plurality of GSLB nodes registered to the directory group. A respective GSLB node is configured to provide GSLB services over a respective portion of the resources. A directory node includes a domain name system (DNS) query-receiving module configured to receive a DNS query from a client, a node-selecting module configured to select from the plurality of GSLB nodes a first GSLB node based at least on the DNS query, and a DNS query-responding module configured to respond to the DNS query to the client using an address of the selected first GSLB node, thereby facilitating the selected first GSLB node in performing GSLB while resolving the DNS query.

Abstract: Techniques are described for distributed processing of Internet of Things (IoT) device data by edge systems co-located within a globally-distributed set of co-location facilities deployed and managed by a co-location facility provider. For example, a method includes selecting, by at least one of a plurality of edge computing systems co-located within respective co-location facilities each deployed and managed by a single co-location facility provider, a selected edge computing system of the plurality of edge computing systems to process data associated with events generated by an IoT device. The method also includes provisioning, at the selected edge computing system, an application programming interface (API) endpoint for communication with the IoT device, receiving, by the selected edge computing system at the endpoint, the data associated with the events generated by the IoT device, and processing, by the selected edge computing system, the data associated with the events generated by the IoT device.

Abstract: A method and system for load balancing over a cluster of authentication, authorization and accounting (AAA) servers. The method performs a distribution of AAA requests among AAA servers having an active AAA connection with an AAA client. The method includes establishing TCP connections with a plurality of AAA servers, using a TCP connection request received from at least one AAA client; opening AAA connections with a plurality of AAA servers, using an AAA connection request received from at least one AAA client, and distributing AAA requests to AAA servers with an active AAA connection according to a predefined load balancing algorithm. The invention is further capable of multiplexing outbound messages and requests received from a plurality of AAA servers. The AAA protocol supported by the invention includes, but is not limited to, a Diameter protocol, a lightweight directory access protocol (LDAP), and the likes.

Abstract: A new approach is proposed that contemplates systems and methods to support bulk authentication of an appliance associated with a user to all cloud-based services the appliance intends to access in one transaction instead of authenticating the appliance against each of the services individually. First, the appliance generates and transmits to an authentication service cluster an authentication request that includes its identification and authentication credentials in order to access to a plurality of services. Upon receiving the authentication request, the authentication service cluster authenticates the appliance for all of the services to be accessed based on the information in the authentication request. Once the appliance is authenticated, the authentication service cluster then retrieves entitlement information of the services to be accessed by the appliance, and identifies the service clusters/nodes that the appliance will connect to for the services with the fastest response time.

Abstract: A system, method and computer program product for allocating shared resources. Upon receiving requests for resources, the system determines whether there are any pending updates for a VM image for provisioning a virtual machine (VM) for the request. For each image with pending updates the system determines whether to replace the stored image with an updated VM image and provision from the replacement or, update a single instance of the image and provision from the single instance. The system also determines an optimal time to update images with pending updates. After replacing an image, the system provides an alert indicating that an updated said VM was provisioned.

Abstract: Performing maintenance to controllers in a network-attached storage system that includes two or more controllers, each controller including at one or more associated IP address. An online controller in the network-attached storage system to upgrade is identified. The IP addresses of the online controller to upgrade is moved to another controller in the network-attached storage system. Simultaneous with when the other controller is online, the online controller to upgrade is taken offline and upgraded the controller to upgrade.
