    摘要: Methods and apparatus are provided for improving fiber channel packet delivery. Techniques are provided for the in-order delivery of packets by blocking incoming packets associated with a port channel change at a fiber channel switch and sending flush messages onto links associated with a port channel change. Upon receiving acknowledgments for the flush messages, incoming packets are unblocked.

    摘要: According to the present invention, methods and apparatus are provided to improve the techniques and mechanisms for forwarding packets at a fiber channel switch. A combined area table/domain table (ATDT) is accessed using destination information associated with a fiber channel packet. Area/port or domain information can be used to address entries in the ATDT. Each entry provides one or more paths to a given destination. Traffic shaping, load balancing, and other policy based forwarding considerations can be applied.

    摘要: Methods and apparatus are provided for efficiently selecting virtualization engines in storage area networks. Initiators, targets, and candidate virtualization engines associated with a virtual logical unit number (VLUN) are identified and characteristics such as latency, network topology, load, and mirroring and striping characteristics are analyzed and used to efficiently select a virtualization engine for a particular VLUN in a storage area network. A virtualization engine can be implemented in a line card associated with a fibre channel switch.

    摘要: According to the present invention, methods and apparatus are provided to improve the link state routing protocol (LSRP) to prevent transient loops during topology changes. Broadcast and shared multicast traffic is dropped upon detecting link state change until neighboring nodes have computed routes using updated link state information. An acknowledgment for a link state record is sent only after route computation is complete using updated link state information.

    摘要: A transmission node for use in a wireless communication network includes a first CPRI unit for transmitting auxiliary data to a second CPRI unit in the transmission node. A memory unit stores control word data of the auxiliary data. A memory write block is connected between the first CPRI unit and the memory unit for writing the control word data to the memory unit based on a first set of frame timing signals received from the first CPRI unit. A memory read and merge block is connected to the memory unit for reading the control word data stored in the memory unit based on a second set of frame timing signals, merging the control word data with IQ data, and transmitting the merged auxiliary data to the second CPRI unit.

    摘要: Virtual data stores may be sparsely provisioned by virtual data storage services in a manner that controls risk of implementation resource shortages. Relationships between requested data storage space size, data storage server capacity, allocated data storage space size and/or allocated data storage space utilization may be tracked on a per data store, per customer, per data storage server, and/or a per virtual data storage service basis. For each such basis, a set of constraints may be specified to control the relationships. The set of constraints may be enforced during implementation resource allocation, and by migration of data storage space portions to different implementation resources as part of a sparse provisioning load balancing. Sparse provisioning details may be made explicit to virtual data storage service customers to varying degrees including explicit, aggregate on a per customer basis, and aggregate on a per virtual data storage service basis.
