    • An approach for managing a data package is provided. Network throughput is determined to exceed a threshold. A sender computer determines a hash digest of the data package by using a hash function selected based on central processing unit utilization. If the hash digest is in a sender hash table, then without sending the data package, the sender computer sends the hash digest and an index referring to the hash digest so that a recipient computer can use the index to locate a matching hash digest and the data package in a recipient hash table. If the hash digest is not in the sender hash table, then the sender computer adds the data package and the hash digest to the sender hash table and sends the data package and the hash digest to the second computer to check the integrity of the data package based on the hash digest.
    • 提供了一种用于管理数据包的方法。 网络吞吐量被确定为超过阈值。 发送者计算机通过使用基于中央处理单元利用率选择的散列函数来确定数据包的散列摘要。 如果散列摘要位于发送者散列表中,则不发送数据包,发送者计算机发送散列摘要和引用散列摘要的索引,以便收件人计算机可以使用索引来定位匹配的散列摘要, 数据包在收件人哈希表中。 如果散列摘要不在发送方散列表中,则发送方计算机将数据包和散列摘要添加到发送者散列表,并将数据包和散列摘要发送到第二台计算机,以检查数据包的完整性 基于哈希摘要。

    • An apparatus, system, and method are disclosed for handling data being communicated over lossless Ethernet that is sensitive to delays. Fibre Channel over Ethernet (FCoE) is one example of an environment where data may be subject to unacceptable delays. The method involves designating certain data as low latency data that is sensitive to delays in transmission. The low latency data is then transmitted in such a manner that the receiving devices are aware that they are receiving low latency data. If a delay in the transmission of low latency is detected, commands are issued that pause or slow standard data in order to free up bandwidth for the low latency data. The commands may be, for example, backward congestion notifications and priority flow control. Low latency data is exempted from backward congestion notifications and priority flow control. Priority 7 priority group 15 may be reserved exclusively for low latency data.
    • 公开了一种用于处理通过对延迟敏感的无损以太网传送的数据的装置,系统和方法。 以太网光纤通道(FCoE)是数据可能遭受不可接受的延迟的一个例子。 该方法包括将某些数据指定为对传输延迟敏感的低延迟数据。 然后以这样的方式传送低延迟数据,使得接收设备知道它们正在接收低延迟数据。 如果检测到低延迟传输的延迟,则发出暂停或减慢标准数据的命令,以释放低延迟数据的带宽。 这些命令可以是例如反向拥塞通知和优先级流控制。 低延迟数据免于后向拥塞通知和优先流控制。 优先级7优先级组15可以专门用于低延迟数据。
