Systems, methods, and computer-readable media are disclosed for an apparatus coupled to a communication bus, where the apparatus includes a queue and a controller to manage operations of the queue. The queue includes a first space to store a first information for a first traffic type, with a first flow class, and for a first virtual channel of communication between a first communicating entity and a second communicating entity. The queue further includes a second space to store a second information for a second traffic type, with a second flow class, and for a second virtual channel of communication between a third communicating entity and a fourth communicating entity. The first traffic type is different from the second traffic type, the first flow class is different from the second flow class, or the first virtual channel is different from the second virtual channel. Other embodiments may be described and/or claimed.

A network interface controller (NIC) capable of on-demand paging is provided. The NIC can be equipped with a host interface, an operation logic block, and an address logic block. The host interface can couple the NIC to a host device. The operation logic block can obtain from a remote device, a request for an operation based on a virtual memory address. The address logic block can obtain, from the operation logic block, a request for an address translation for the virtual memory address and issue an address translation request to the host device via the host interface. If the address translation is unsuccessful, the address logic block can send a page request to a processor of the host device via the host interface. The address logic block can then determine that a page has been allocated in response to the page request and reissue the address translation request.

Techniques are disclosed relating to handling queues. A server-based platform, in some embodiments, accesses queue information that includes performance attributes for a plurality of queues storing one or more messages corresponding to one or more applications. In some embodiments, the platform assigns, based on the performance attributes, a corresponding set of the plurality of queues to each of a plurality of processing nodes of the platform. In some embodiments, the assigning of a corresponding set of queues to a given one of the plurality of processing nodes causes instantiation of: a first set of one or more dequeuing threads and a second set of one or more processing threads. The dequeuing threads may be executable to dequeue one or more messages stored in the corresponding set of queues. The processing threads may be executable to perform one or more tasks specified in the dequeued one or more messages.

A network device includes one or more ports, a packet processor, and a memory management circuit. The one or more ports are to communicate packets over a network. The packet processor is to process the packets using a plurality of queues. The memory management circuit is to maintain a shared buffer in a memory and adaptively allocate memory resources from the shared buffer to the queues, to maintain in the memory, in addition to the shared buffer, a shared-reserve memory pool for use by a defined subset of the queues, to identify in the subset a queue that (i) requires additional memory resources, (ii) is not eligible for additional allocation from the shared buffer, and (iii) meets an eligibility condition for the shared-reserve memory pool, and to allocate memory resources to the identified queue from the shared-reserve memory pool.

Systems and methods are provided for efficiently routing data through a network having a plurality of switches configured in a fat-tree topology, including: receiving a data transmission comprising a plurality of packets at an edge port of the network, and routing the data transmission through the network with routing decisions based upon a routing table, wherein the routing table includes entries to effect routing decisions based upon a destination based hash function.

A packet filtering system uses linked zero-based binary search trees to filter received packets. The binary search trees may be generated from filter conditions defining filter parameters for filtering packets.
