Abstract: The invention relates to an arrangement for load sharing in computer networks and, more exactly, an arrangement for distribution of traffic, for instance via Internet, from clients (1) to service suppliers who provide services from many servers. The invention makes possible distribution to one of a number of replicated servers. Suitable server is selected for instance on basis of available resources at the interface of the server, or less delay in the transmission. The invention results in better performance and reduced traffic by distribution of the traffic geographically and from a resource point of view. According to the invention, a number of replicated servers (5A-5E) belong to an anycast-group and each anycast-group is connected to a domain name server (2) which has the ability to select one of the replicated servers, so that a router (4) can establish a connection between the selected server and the service-requesting client computer. Each replicated server (5A-5E) can transmit a resource advertisement which contains information about available resources at the server in question, and about the link parameters of the server.

Abstract: A system establishes virtual DNS servers that are supported by a DNS server. Target IP addresses are assigned for the virtual DNS servers. Network capable devices are uniquely assigned to the virtual DNS servers for domain name resolution. Each network capable device accesses the communication network through a corresponding network device associated with a corresponding source IP address. A client's service plan is assigned to a first network capable device used by the client. The service plan is implemented through a DNS request under a session established between the first network capable device and its assigned first virtual DNS server. The session is uniquely identified by a first source IP address of a first network device used by the first network capable device to access the communication network and a first target IP address of the first virtual DNS server.

Abstract: A push messaging platform includes a push server system having push engines (PE) for maintaining persistent connections with mobile devices, and push controllers (PC) for maintaining records of mobile devices' connections. The platform provides high scalability by including a load balancer for distributing connection requests received from mobile devices across the PEs, and dispatchers for forwarding each received message to a PC associated with the mobile device identified in the message. The platform provides high availability by using local backup PCs and remote mirror PCs. A global registered process (GRP) on each PC is linked to a process on a backup PC, and the backup process replaces the GRP if the GRP fails. Local registered processes (LRP) on each PC are linked to corresponding processes on a remotely located mirror PC, and the mirror process replaces the LRP if the LRP fails.

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: A packet data serving node (PDSN) manages sessions between mobile devices and a packet-based network. The PDSN sends requests to and receives responses from an authentication, authorization, and accounting (AAA) server. The PDSN includes a packet session manager configured to create, maintain, and terminate the sessions between mobile devices and the packet-based network. The PDSN also includes a global AAA manager configured to determine latency in communication between the PDSN and the AAA server based on latencies of responses to at least two requests which the PDSN sends to the AAA server. The global AAA manager determines an adjustment in a load which may be imposed on the AAA sever based on the determined latency and causes the determined adjustment in the load which may be imposed on the AAA server to be implemented.

Abstract: Techniques are provided herein for a device in a network to receive information configured to indicate a control plane traffic load level for one or more server devices that are configured to manage traffic for messaging and presence clients communicating via a messaging and presence protocol. The control plane traffic is associated with the messaging and presence protocol. A determination is made as to when the control plane traffic load level has become unbalanced among the two or more server devices and in response to determining that the control plane traffic load level has become unbalanced, sending a transfer message to one or more clients comprising information configured to initiate migration of one or more clients from a server device that is relatively overloaded to a server device that is relatively underloaded in order to balance the control plane traffic load level among the two or more server devices.

Abstract: A system and method for selecting an optimal authoritative name server includes global authoritative name servers and regional authoritative name servers. The local name server receives a request for target objects from a client. The local name server inquires one of the global authoritative name servers about an IP address of a requested domain. The selected global authoritative name server initially responds to the local name server. For subsequent requests, the selected global authoritative name server guides the local name server to inquire one of the regional authoritative name servers by providing a new authoritative name server list including a group of regional authoritative name servers designated to serve a network location of the local name server. The system and method for selecting the optimal authoritative name server may have practical applications in a content delivery network system.

Abstract: A system, method and computer-readable medium for request routing. A client request processing a resource identifier for requested content transmits a first DNS query to a content delivery network service provider. The content delivery network service provider transmits an alternative resource identifier in response to the client computing device DNS query. The client computing device then issues a second DNS query to the same content delivery network service provider. The content delivery network service provider can then either resolve the second DNS query with an IP address of a cache component or transmit another alternative resource identifier that will resolve to the content delivery network service provider. The process can repeat with the content delivery network service provider's network until a DNS server resolves a DNS query from the client computing device.

Abstract: A method and apparatus for serving content requests using global and local load balancing techniques is provided. Web site content is cached using two or more point of presences (POPs), wherein each POP has at least one DNS server. Each DNS server is associated with the same anycast IP address. A domain name resolution request is transmitted to the POP in closest network proximity for resolution based on the anycast IP address. Once the domain name resolution request is received at a particular POP, local load balancing techniques are performed to dynamically select the appropriate Web server at the POP for use in resolving the domain name resolution request. Approaches are described for handling bursts of traffic at a particular POP, security, and recovering from the failure of various components of the system.

Abstract: The present disclosure presents systems and methods for obtaining metric information by a multi-core GSLB intermediary device and providing global server load balancing services using the obtained information. A first core of a multi-core GSLB appliance establishes a transport layer connection to a remote load balancer at a site of a plurality of sites. The first core transmits a message to each of the other cores of the multi-core GSLB appliance that that the first core is a master core for receiving metric information from the load balancer. The first core receives metric information of the remote site from the load balancer. The first core propagates the metric information to each of the other cores of the GSLB appliance. A GSLB virtual server on a slave core receives a DNS request. The GSLB virtual server determines a DNS resolution for the DNS request based on the metric information.
