Abstract: Various embodiments are generally directed to techniques for improving the efficiency of exchanging packets between pairs of VMs within a communications server. An apparatus may include a processor component; a network interface to couple the processor component to a network; a virtual switch to analyze contents of at least one packet of a set of packets to be exchanged between endpoint devices through the network and the communications server, and to route the set of packets through one or more virtual servers of multiple virtual servers based on the contents; and a transfer component of a first virtual server of the multiple virtual servers to determine whether to route the set of packets to the virtual switch or to transfer the set of packets to a second virtual server of the multiple virtual servers in a manner that bypasses the virtual switch based on a routing rule.

Abstract: The present disclosure describes a process and apparatus for improving insertions of entries into a hash table. A large number of smaller virtual buckets may be combined together and associated with buckets used for hash table entry lookups and/or entry insertion. On insertion of an entry, hash table entries associated with a hashed-to virtual bucket may be moved between groups of buckets associated with the virtual bucket, to better distribute entries across the available buckets to reduce the number of entries in the largest buckets and the standard deviation of the bucket sizes across the entire hash table.

Abstract: Technologies for dynamically managing a batch size of packets include a network device. The network device is to receive, into a queue, packets from a remote node to be processed by the network device, determine a throughput provided by the network device while the packets are processed, determine whether the determined throughput satisfies a predefined condition, and adjust a batch size of packets in response to a determination that the determined throughput satisfies a predefined condition. The batch size is indicative of a threshold number of queued packets required to be present in the queue before the queued packets in the queue can be processed by the network device.

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.

Abstract: A network interface card (NIC) can be configured to monitor a first central processing unit (CPU) core mapped to a first receive queue having a receive queue length. The NIC can also be configured to determine whether the CPU core is overloaded based on the receive queue length. The NIC can also be configured to redirect data packets that were targeted from the first receive queue to the CPU core to another CPU core responsive to a determination that the CPU core is overloaded.

Abstract: Techniques for modifying a transmission rate of a device having a plurality of transmission rate options are described herein. The techniques include a method comprising receiving data from a sensor indicating movement of an electronic device, the electronic device having a plurality of transmission rate options. Fail ratio metrics are gathered. The fail ratio metrics indicate a ratio of failed transmissions to successful transmissions for rate option during device movement. The method includes determining whether a given rate option has a fail ratio above a predetermined threshold; and, if so, disabling the given rate option while the device is moving.

Abstract: Computer-readable storage media, computing devices and methods associated with file cache management are discussed herein. In embodiments, a computing device may include a file cache and a file cache manager coupled with the file cache. The file cache manager may be configured to implement a context-aware eviction policy to identify a candidate file for deletion from the file cache, from a plurality of individual files contained within the file cache, based at least in part on file-level context information associated with the individual files. In embodiments, the file-level context information may include an indication of access recency and access frequency associated with the individual files. In such embodiments, identifying the candidate file for deletion from the file cache may be based, at least in part, on both the access recency and the access frequency of the individual files. Other embodiments may be described and/or claimed.
