    • The subject disclosure is directed towards a data deduplication technology in which a hash index service's index and/or indexing operations are adaptable to balance deduplication performance savings, throughput and resource consumption. The indexing service may employ hierarchical chunking using different levels of granularity corresponding to chunk size, a sampled compact index table that contains compact signatures for less than all of the hash index's (or subspace's) hash values, and/or selective subspace indexing based on similarity of a subspace's data to another subspace's data and/or to incoming data chunks.

    • A top level domain name system (DNS) server receives a DNS query from a local DNS resolver, the DNS query requesting a network address corresponding to a domain name. The top level DNS server reflects the local DNS resolver to a reflector DNS server. The reflector DNS server reflects the local DNS resolver to a collector DNS server, which in turn returns the network address to the local DNS resolver. The reflector DNS server and collector DNS server are both in the same data center, and one or more network performance measurements for communications between the local DNS resolver and the data center are determined based on the communications between the local DNS resolver and both the reflector DNS server and the collector DNS server.

    • In various embodiments, methods and systems are disclosed for a hybrid rate plus window based congestion protocol that controls the rate of packet transmission into the network and provides low queuing delay, practically zero packet loss, fair allocation of network resources amongst multiple flows, and full link utilization. In one embodiment, a congestion window may be used to control the maximum number of outstanding bits, a transmission rate may be used to control the rate of packets entering the network (packet pacing), a queuing delay based rate update may be used to control queuing delay within tolerated bounds and minimize packet loss, and aggressive ramp-up/graceful back-off may be used to fully utilize the link capacity and additive-increase, multiplicative-decrease (AIMD) rate control may be used to provide fairness amongst multiple flows.

    • Distributed computing devices comprising a system for sharing computing resources can provide shared computing resources to users having sufficient resource credits. A user can earn resource credits by reliably offering a computing resource for sharing for a predetermined amount of time. The conversion rate between the amount of credits awarded, and the computing resources provided by a user can be varied to maintain balance within the system, and to foster beneficial user behavior. Once earned, the credits can be used to fund the user's account, joint accounts which include the user and others, or others' accounts that do not provide any access to the user. Computing resources can be exchanged on a peer-to-peer basis, though a centralized mechanism can link relevant peers together. To verify integrity, and protect against maliciousness, offered resources can be periodically tested.
    • 包括用于共享计算资源的系统的分布式计算设备可以向具有足够资源信用的用户提供共享的计算资源。 用户可以通过可靠地提供用于共享预定时间量的计算资源来获得资源信用。 可以改变授予的学分数量和用户提供的计算资源之间的转换率,以保持系统内的平衡,并促进有益的用户行为。 一旦获得,信用额可以用于为用户的帐户,包括用户和其他人的联合账户或不提供对用户的访问的其他账户提供资金。 计算资源可以在对等的基础上交换,尽管集中的机制可以将相关的对等体链接在一起。 为了验证完整性,并防止恶意,提供的资源可以定期测试。

    • An erasure resilient coding (ERC) distributed data storage system and method for storing data in a reliable and survivable fashion while minimizing hardware and associated costs. The system and method includes forming multiple protection groups both within and across storage nodes of the storage system. Data is segmented into original data blocks and ERC data blocks. Load balancing occurs by interleaving storage nodes with equal numbers of original data blocks and ERC data blocks while ensuring each node has an equal number of combined read and write operations. Unique read and write operations on data block can be performed independent of other data blocks in a protection group. The write operation uses Galois field arithmetic and ERC transform to either write or append a new data block to a storage node. The read operation recovers data in a variety of ways using ERC decoding.
