摘要:
The link status of a Fibre-Channel link interconnecting two Fibre-Channel ports may be determined by a third entity distinct from the two Fibre-Channel ports. The third entity may be a transport interface used to connect one of the Fibre-Channel ports to a transport network that carries the link. The transport interface may also learn the Fibre-Channel port types of the two ports.

The Fibre-Channel flow control mechanism is augmented to facilitate efficient data exchange between Fibre-Channel ports over extended distances. A supplemental buffer mechanism may be maintained as part of an interface to a transport network used to carry Fibre-Channel traffic. The transport network interface makes a remote Fibre-Channel port aware of the augmented local receiver buffer capacity by intercepting certain frames used in link establishment and substituting an enhanced buffer capacity for the local Fibre-Channel port's internal buffer capacity. This technique provides improved throughput and readily accommodates large distances and large frame sizes.

Systems and methods for carrying a serial digital video stream over an optical network such as an optical network employing SONET/SDH or G.709. For example, serial digital video data formatted in accordance with ANSI/SMPTE 259 M-1997 may be carried. Also, a common interface may be provided for both serial digital video streams and packetized digital video data such as DVB-ASI data.
摘要:
Fiber-Channel links are carried over transport networks such as optical transport networks. In certain embodiments, available transport network capacity is over-subscribed by Fiber-Channel links. This may be accomplished by buffering Fiber-Channel traffic at the ingress of the transport network and selecting frames to inject into the transport network from the buffers. Transport network efficiency can therefore be greatly increased by use of statistical multiplexing. Ready signals from the receiving Fiber-Channel ports may be delayed before being relayed to the transmitting Fiber-Channel ports.

A method for creating a configurable model for rating and metering resource usage, the method includes utilizing at least one rating context for a contract of a registered offering, wherein the registered offering is a resource, monitoring the resource usage to create a usage record, optimizing the collection of the usage data based on revenue potential and metering costs, contextualizing a usage record of the resource, generating rated usage data according to the usage record, and tuning a performance indicator of a metering definition for the registered offering based on the rated usage data.
摘要:
Methods, apparatus, and articles of manufacture are disclosed. These perform the following: accessing records of previous usage within a billing period of service units for customers, wherein the service units are discrete sizes of services for resource types, wherein each usage of an individual one of the service units has start and stop events, and wherein each resource type has a price fixed as of a date of the previous usage; dividing the billing period into time periods determined using the start and stop events for the usage of all of the service units; using the accessed records and the time periods and based on one or more criteria, assigning resource types to the previous usage in the time periods of the service units by the customers; and determining total charge for a selected customer based on the assignments of the resource types and corresponding prices for the selected customer.
