Abstract: Disclosed are methods and apparatus for redirecting fibre channel data that is transmitted between a first and a second node, such as a host and target, in a storage area network (SAN) to an intelligent node that facilitates implementation of a service on such redirected data. Such redirection is provided transparently with respect to the first and second nodes without significantly reconfiguring the existing infrastructure of the first and second nodes. In a specific Fibre Channel implementation, the redirection is accomplished without rewiring any of the nodes in the network fabric or reconfiguring zones or virtual storage area networks (VSANs). In general, such redirection is accomplished by rewriting the data as it traverses on a path between the first and second node towards an original destination (e.g., the first or second node) so that the data is redirected to an intelligent node. The intelligent node then facilitates implementation of a service on such redirected data and then forwards the serviced data back to its original destination. In one example, setup of this redirection function is accomplished simply by making a request to a network device (e.g., a host and/or target switch) in the first and second node's communication path, where the request identifies the first node, the second node, and the intelligent node.

Abstract translation: 公开了用于将存储区域网络（SAN）中的诸如主机和目标的第一和第二节点之间传输的光纤通道数据重定向到便于在这种重定向数据上实现服务的智能节点的方法和装置 。 这样的重定向相对于第一和第二节点透明地提供，而不显着地重新配置第一和第二节点的现有基础设施。 在特定的光纤通道实现中，重定向是在不重新布线网络结构中的任何节点或重新配置区域或虚拟存储区域网络（VSAN）的情况下实现的。 通常，通过在数据在第一和第二节点之间的路径上朝向原始目的地（例如，第一或第二节点）重写数据以使得数据被重定向到智能节点来实现这种重定向。 智能节点然后促进对这种重定向数据的服务的实现，然后将服务数据转发回其原始目的地。 在一个示例中，通过向第一和第二节点的通信路径中的网络设备（例如，主机和/或目标交换机）发出请求来简单地完成该重定向功能的设置，其中请求标识第一节点，第二节点 节点和智能节点。

Abstract: The Switch includes a port configured to receive a command frame when installed in a switching Fabric. The frame identifies a source device and a destination device in the Switching Fabric, a command, and a read/write flag which indicates if the identified source intends to exercise read-only or write access to the destination device. The Switch also includes a processor coupled to the port. The processor is configured to trap the frame and prevent it from reaching the defined destination device in the switching Fabric if both the source and destination devices are in a read-only zone and the flag indicates that the source intends to write to the destination device. In this manner, read-only zones can be implemented in the Switching Fabric.

Abstract translation: 交换机包括一个配置为在安装在交换矩阵中时接收命令帧的端口。 帧标识切换结构中的源设备和目标设备，命令和读/写标志，其指示所识别的源是否旨在对目标设备执行只读或写访问。 交换机还包括耦合到端口的处理器。 如果源设备和目标设备都在只读区域，并且该标志指示源意图写入目标设备，则处理器被配置为捕获帧并阻止它到达交换结构中的定义的目的地设备。 以这种方式，可以在交换结构中实现只读区域。

Abstract: A method and system for synchronizing clocks in a packet network that includes a master node and at least one slave node that communicate with one another is disclosed. A timer value from a master clock is retrieved upon transmission of a first packet to the slave node. The timer value and an associated code are subsequently sent to the slave node in a subsequent packet. After receiving the first packet, the slave node, retrieves a timer value from a slave clock and associates it with an identifying code of the first packet. After receiving the subsequent packet, the slave node relates the timer values and adjusts a clock value of the slave clock accordingly. An interrupt scheme may be used to implement the retrieval of the timer values.

Abstract: A pelletizable gunning composition is provided which exhibits excellent flow characteristics, minimal release of dust, and excellent adhesion and resistance to slag. The gunning composition includes high density magnesium oxide as the primary component, and lesser quantities of powdered metal, refractory clay, binder and, preferably, graphite. The dry components are mixed together, and the binder is added and mixed, resulting in a composition that can be pelletized. After pelletizing, the composition can be coated with a dusting material to facilitate pellet flow and prevent pellet agglomeration.

Abstract: An improved ramming composition for use in the iron and steel industry includes between 65-80% by weight mullite, 5-15% by weight silicon carbide, 2-5% by weight graphite, 2-6% by weight ball clay, and 5-10% by weight of a binder formed from a dispersion of 15-70% by weight silica in water. The silica binder replaces binders composed of petroleum pitch, clay, or other organic materials. The silica binder causes the ramming composition to have a longer use life, increased strength, and reduced tendency to crack, oxidize or smoke.
