In one aspect, the present disclosure relates to a method comprising: receiving, at a client device, information from a node manager about a plurality of nodes in a computer cluster, the information comprising a network address associated each of the plurality of nodes and sending, by the client device, a request to a load balancer to access a first node from the plurality of nodes, the request comprising a first URL including an encoded representation of the network address associated with the first node. The load balancer is configured to determine the request should be routed to a first network address based on decoding the URL, the first network address associated with a first node from the plurality of nodes and forward the request to the first node in response to the determining.

Embodiments enable seamless Wi-Fi roaming by providing a user with a single username that is associated with a set of resources in the seamless network that includes different Wi-Fi networks (e.g., Wi-Fi networks with different domain names). As a user travels from a first access point in a first Wi-Fi network to a second access point in a second Wi-Fi network within the seamless network, network elements in the seamless network may recognize the user's single username as an already established session (e.g., with the first access point) and direct traffic accordingly to the second access point. Embodiments also satisfy business requirements by updating accounting data accordingly by indicating that the user accessed the seamless network from the first Wi-Fi network. Embodiments allow a user roaming on the seamless network to experience the policies and network requirements associated with the Wi-Fi domain of the second access point.

In one embodiment, a domain name system (DNS) server processes a DNS query based on a policy statement that is attached to the DNS query. Upon receiving the DNS query, the DNS server executes one or more commands specified in the policy statement to generate a query state. The query state controls DNS resolution behavior that the DNS server implements as part of processing the DNS query. The DNS server then performs one or more DNS resolution operations based on DNS query and the query state to generate a response. Advantageously, because the semantics of the policy statement are encapsulated within the policy statement, the policy statement enables a client to unambiguously control DNS resolution behavior. By contrast, conventional DNS resolution guidance mechanisms that rely on DNS servers to infer policies based on client data may not reflect the preferences of the clients.

Systems and methods for InfiniBand fabric optimizations to minimize SA access and startup failover times. A system can comprise one or more microprocessors, a first subnet, the first subnet comprising a plurality of switches, a plurality of host channel adapters, a plurality of hosts, and a subnet manager, the subnet manager running on one of the one or more switches and the plurality of host channel adapters. The subnet manager can be configured to determine that the plurality of hosts and the plurality of switches support a same set of capabilities. On such determination, the subnet manager can configure an SMA flag, the flag indicating that a condition can be set for each of the host channel adapter ports.

Systems, apparatuses, and methods for generating network messages on a parallel processor are disclosed. A system includes at least a parallel processor, a general purpose processor, and a network interface unit. The parallel processor includes at least a plurality of compute units, a command processor, and a cache. A thread within a kernel executing on a compute unit of the parallel processor generates a network message and stores the network message and a corresponding indication in the cache. In response to detecting the indication of the network message in the cache, the command processor processes and conveys the network message to the network interface unit without involving the general purpose processor.
