Abstract: A method that provides for the grouping under a same workload of both application instances in an application tier, and data sharing members in a data tier. This grouping enables a workload manager to make recommendations (to load balancer appliances) about how to distribute workload connections, e.g., based on metrics gathered from both the application and data tiers. In this approach, both applications and data sources are grouped into a workload grouping, and health, status and capacity information about both of these tiers (application and data) is then used to determine an overall distribution policy for the workload. These different tiers can reside on the same or different operating system environments.

Abstract: There are provided measures for enabling/realizing an integrity check of a DNS server setting, thereby enabling/realizing detection of DNS hacking or hijacking. Such measures could exemplarily include triggering a DNS resolution operation by a service device configured to provide a service using the DNS server setting, wherein the DNS server setting is used for DNS resolution or DNS forwarding in service provisioning, acquiring the IP address of a DNS server device, which is configured to perform DNS resolution in service provisioning, by reading the IP address of the DNS server device included in a DNS message as part of the triggered DNS resolution operation by the service device, and processing the acquired IP address of the DNS server device for evaluating integrity of the DNS server setting used in service provisioning.

Abstract: Techniques are described for load balancing between DHCP servers at a DHCP client. Embodiments include receiving, at the DHCP client, a respective DHCPOFFER message from each of two or more DHCP servers, wherein each of the DHCPOFFER messages includes an IP address offer and load information describing a current workload of the respective DHCP server. One of DHCP servers is selected, at the DHCP client, to accept an offer for an IP address from, based on the received load information and a subnet on which the selected DHCP server is located. Embodiments transmit a DHCPREQUEST message, from the DHCP client, to the selected DHCP server, to accept the IP address offer from the selected DHCP server.

Abstract: A Domain Name System (DNS) server that is operable to apply DNS-based load balancing policies based on geolocation and time of day is described herein. In an embodiment, the DNS server determines a geolocation and a time of day associated with a plurality of DNS queries and then obtains a domain name resolution policy that is associated with one or more of the geolocation and the time of day. The policy specifies a plurality of geographically disparate data centers and a ratio by which domain names are to be resolved thereto. The ratio at least specifies that more domain names are to be resolved to one of the plurality of geographically disparate data centers than another. The DNS server applies the domain name resolution policy to resolve the domain names in the DNS queries.

Abstract: A traffic management device (TMD), system, and processor-readable storage medium directed towards automatically configuring an AAA proxy device (also referred to herein as “the proxy”) to load-balance AAA request messages across a plurality of AAA server devices. In one embodiment the proxy receives an AAA handshake message from an AAA client device. The proxy forwards the handshake message to each of the plurality of server devices and, in reply, receives an AAA handshake response message from each of the plurality of server devices. The proxy extracts attributes from each of the handshake response messages and automatically configures itself based on the extracted attributes. The proxy then load-balances, modifies and/or routes subsequently received AAA request messages based on the extracted attributes.

Abstract: A system, method and computer-readable medium for request routing based on content popularity information are provided. A client computing device 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 alternative resource identifier is selected as a function of popularity information pertaining to the requested resource. The client computing device then transmits a second DNS query to the 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 until a DNS nameserver resolves a DNS query from the client computing device.

Abstract: Systems and methods for managing requesting routing functionality associated with resource requests for one or more resources associated with a content provider are provided. A content delivery network (“CDN”) service provider, on behalf of a content provider, can process domain name service (“DNS”) requests for resources by computing devices and resolve the DNS requests by the identification of a network address of a computing device that will provide the requested resources. Based on the processing of DNS queries initiated by a client computing device, the CDN service provider can measure CDN service provider latencies associated with the generation of DNS requests by network components associated with the client computing devices. Examples of the network components can include DNS resolvers associated with the client computing device.
