Abstract: Methods and devices are provided for efficient transmission of data between storage area networks. According to some aspects of the invention, novel methods are provided for processing data packets sent by, or received from, a storage area network. Some such aspects of the invention involve storing a packet (or a portion of a packet) in a single memory location during an encapsulation or de-encapsulation process. Instead of repeatedly copying the packet during processing, pointer information is passed along that indicates the single memory location. In some aspects of the invention, the segment boundaries of a packet are retained after data transmission. If data in the packet need to be re-transmitted, the packet is re-transmitted with the same segment boundaries.

Abstract: Method and devices are provided to form virtual switches for data networks. As noted above, the term “switch” as used herein will apply to switches, routers and similar network devices. Each virtual switch acts as a single logical unit, while encompassing at least two physical chassis. Accordingly, each virtual switch may be treated as a single point of management. Each virtual switch includes a master chassis and at least one slave chassis. The master chassis is configured to control the slave chassis. The master chassis includes at least one master supervisor card and the slave chassis includes at least one slave supervisor card. The master chassis and the slave chassis communicate via a virtual switch link according to a virtual switch link protocol.

Abstract: Methods and devices are provided for efficient transmission of data between storage area networks. According to some aspects of the invention, a “slim” TCP stack is provided which eliminates the socket layer found in a conventional TCP stack, thereby eliminating socket buffers and the associated buffer-to-buffer copying. Moreover, by eliminating the socket layer, one eliminates the listen state. This condition allows TCP processing in an interrupt context instead of client/server operation with a listen state. Accordingly, some aspects of the invention provide for transmitting data between SANs in an interrupt context.

Abstract translation: 提供了方法和设备，用于在存储区域网络之间有效地传输数据。 根据本发明的一些方面，提供了一种“薄型”TCP堆栈，其消除了传统TCP堆栈中发现的套接字层，从而消除了套接字缓冲区和相关的缓冲区到缓冲区复制。 此外，通过消除套接字层，可以消除收听状态。 此条件允许在中断上下文中进行TCP处理，而不是使用监听状态进行客户端/服务器操作。 因此，本发明的一些方面提供了在中断上下文中在SAN之间传输数据。
