    Abstract: Systems, apparatuses and methods may provide for technology that uses centralized hardware to detect a local allocation request associated with a local thread, detect a remote allocation request associated with a remote thread, wherein the remote allocation request bypasses a remote operating system, and process the local allocation request and the remote allocation request with respect to central heap, wherein the central heap is shared by the local thread and the remote thread. The local allocation request and the remote allocation request may include one or more of a first request to allocate a memory block of a specified size, a second request to allocate multiple memory blocks of a same size, a third request to resize a previously allocated memory block, or a fourth request to deallocate the previously allocated memory block.

    Abstract: Technologies for flow rule aware exact match cache compression include multiple computing devices in communication over a network. A computing device reads a network packet from a network port and extracts one or more key fields from the packet to generate a lookup key. The key fields are identified by a key field specification of an exact match flow cache. The computing device may dynamically configure the key field specification based on an active flow rule set. The computing device may compress the key field specification to match a union of non-wildcard fields of the active flow rule set. The computing device may expand the key field specification in response to insertion of a new flow rule. The computing device looks up the lookup key in the exact match flow cache and, if a match is found, applies the corresponding action. Other embodiments are described and claimed.

    Abstract: Apparatus, methods, and systems for tuple space search-based flow classification using cuckoo hash tables and unmasked packet headers are described herein. A device can communicate with one or more hardware switches. The device can include memory to store hash table entries of a hash table. The device can include processing circuitry to perform a hash lookup in the hash table. The lookup can be based on an unmasked key include in a packet header corresponding to a received data packet. The processing circuitry can retrieve an index pointing to a sub-table, the sub-table including a set of rules for handling the data packet. Other embodiments are also described.

    Abstract: In an embodiment, an apparatus is provided that may include circuitry to generate, at least in part, and/or receive, at least in part, at least one request that at least one network node generate, at least in part, information. The information may be to permit selection, at least in part, of (1) at least one power consumption state of the at least one network node, and (2) at least one time period. The at least one time period may be to elapse, after receipt by at least one other network node of at least one packet, prior to requesting at least one change in the at least one power consumption state. The at least one packet may be to be transmitted to the at least one network node. Of course, many alternatives, modifications, and variations are possible without departing from this embodiment.

    Abstract: Technologies for efficient network flow classification include a computing device that receives a network packet that includes a header. The computing device generates a vector Bloom filter (VBF) key as a function of the header and searches multiple VBFs for a VBF that matches the VBF key. Each VBF is associated with a flow sub-table that includes one or more flow rules. Each flow sub-table is associated with a mask length. If a matching VBF is found, the computing device searches the corresponding flow sub-table for a flow rule that matches a masked header of the network packet. If no matching VBF is found or if no matching flow rule is found, the computing device searches all of the flow sub-tables for a flow rule that matches the header. The computing device applies a flow action of a matching flow rule. Other embodiments are described and claimed.
