    • Disclosed are a system, a method and/or an apparatus of a shareable virtual non-volatile storage device for a server. In one embodiment, the system includes a server, a storage array, a management processor, and a switching fabric. The storage array includes a storage device coupled with a controller associated with a shared driver to receive a data request from the server at a remote location from the storage array through the switch fabric via a communication link to direct the data request to the storage device coupled with it and transmit data to the server through the switch fabric. A virtual storage device is generated in the server to enable the server to share the shared driver in the storage array with other servers through the switch fabric between the server and the storage array. The server distributes the data across the storage devices through the shared driver.

    • An efficient and reliable transmission protocol for transmitting multimedia streams from a server to a client computer over a diverse computer network including local area networks (LANs) and wide area networks (WANs) such as the internet. The client computer includes a playout buffer for temporary storage of incoming data packets. When the client computer detects that a data packet has not arrived at said client computer by an expected time of arrival (ETA), a round trip time for the data packet is computed. The round trip time is an estimate of a period beginning from the time a retransmission request is sent to from the client computer to the stream server till the time a copy of the missing data packet is received at the client computer from the stream server in response to the retransmission request. If the round trip time is less than the time remaining before the missing packet is no longer useful to the on-demand application, then a retransmission request packet is sent to the server. Conversely if the round trip time is greater than the time remaining, i.e., the missing packet is likely to arrive after the usefulness of the packet has expired, then sending a retransmission request is likely to result in the late arrival of the missing data packet. Accordingly, the missing packet is discarded. This selective retransmission protocol can also be practiced with dynamic bandwidth selection wherein the transmission rate is dynamically matched to the available bandwidth capacity of the network connection between the server and the client computer.
    • 一种高效可靠的传输协议,用于通过包括诸如因特网的局域网(LAN)和广域网(WAN)在内的各种计算机网络从服务器向客户端计算机传输多媒体流。 客户端计算机包括用于临时存储输入数据分组的播出缓冲器。 当客户端计算机检测到数据分组未到达所述客户端计算机达预期到达时间(ETA)时,计算数据分组的往返时间。 往返时间是从重发请求发送到客户端计算机到流服务器的时间段的估计,直到响应于客户端计算机在客户端计算机上接收到丢失数据分组的副本 到重传请求。 如果往返时间小于丢失分组对于按需应用不再有用的时间,则向服务器发送重传请求分组。 相反,如果往返时间大于剩余时间,即丢失的分组可能在分组的有用性已经到期之后到达,则发送重传请求很可能导致丢失的数据分组的迟到。 因此,丢弃丢包。 这种选择性重传协议也可以用动态带宽选择来实现,其中传输速率与服务器和客户端计算机之间的网络连接的可用带宽容量动态匹配。

    • A method in a computer network for automatically detecting a most advantageous protocol for communication by a client computer, said client computer being configured to be coupled to a server computer via a computer network. The method includes initiating a plurality of protocol threads for sending from the client computer to the server computer, a plurality of data requests. Each of the data requests employs a different protocol and a different connection. The data requests are configured to solicit, responsive to the data request, a set of responses from the server computer. Each of the responses employs a protocol associated with a respective one of the data requests. The method further includes receiving at the client computer at least a subset of the responses. The method also includes initiating a control thread at the client computer. The control thread monitors the subset of the responses as each response is received from the server computer to select the most advantageous protocol from protocols associated with the subset of the responses, wherein the most advantageous protocol is determined based on a predefined protocol priority.
    • 一种计算机网络中的用于自动检测由客户计算机进行通信的最有利协议的方法,所述客户端计算机被配置为经由计算机网络耦合到服务器计算机。 该方法包括发起多个协议线程,用于从客户计算机向服务器计算机发送多个数据请求。 每个数据请求采用不同的协议和不同的连接。 数据请求被配置为响应于数据请求请求来自服务器计算机的一组响应。 每个响应采用与相应的数据请求相关联的协议。 该方法还包括在客户端计算机处接收响应的至少一个子集。 该方法还包括在客户端计算机上启动控制线程。 当从服务器计算机接收到每个响应时,控制线程监视响应的子集,以从与响应子集相关联的协议中选择最有利的协议,其中基于预定义的协议优先级来确定最有利的协议。
