摘要： A deterministic and jitter-free dual chamber brady pacemaker utilizes both a programmed microprocessor and a hardware state machine, both of which are coupled to a real time clock (RTC), random access memory (RAM) and a common escape interval timer. Time of occurrence (TOC) data representative of the time and nature of atrial and ventricular sensed events and pacing events is stored in the RAM. Escape interval periods are timed by the escape interval timer. The microprocessor is operable in both an active mode and an inactive mode without interrupts. In response to the receipt of wakeup commands, the microprocessor operates in the active mode and uses the TOC data from the RAM to reset the escape interval timer to a desired next event interval. The hardware state machine uses the common escape interval timer for timing timeout events and atrial and ventricular sensed events such that pacing pulses are delivered in a determinate manner.

摘要： Method and system for routing fibre channel frames using a fibre channel switch element is provided. The method includes, inserting a time stamp value in a fibre channel frame that is received at a receive segment of the fibre channel switch element; determining if a timeout occurs after a frame arrives at a receive buffer; and processing the frame if the timeout occurred. The method also includes, determining if a delta time value, which provides an accumulated wait time for a frame, is present in frame data; subtracting the delta time stamp value from a global time stamp value and using the resulting time stamp value to determine frame timeout status in the fibre channel switch element. A timeout checker circuit declares a timeout after comparing a time stamp value that is inserted in a fibre channel frame with a programmed time out value and a global counter value.

摘要： Hardware-enforced zoning is provided in Fibre Channel switches to protect against breaching of assigned zones in a switch network which can occur with software-based zoning techniques. The invention provides logic for performing a hardware-based validation of the Source ID S_ID of frames both at the point where the frame enters the Fibre Channel fabric, and at the point where the frame leaves the fabric. The S_ID is verified against an inclusion list or table of allowable S_IDs, which can be unique for each fabric port. The invention provides a way to increase the range of sources an inclusion table can express, by implementing wild cards, on an entry-by entry basis. If the S_ID is valid, it will enter the fabric and route normally. If invalid, the frame will not be routed but will be disposed of by the fabric according to FC rules. This prevents incorrect S_IDs from breaching the table-driven zoning at the point where frames exit the fabric, to prevent unauthorized access to devices connected to the switch network.

摘要： A fibre channel switch element and method for processing frames in a fibre channel network is provided. The switch element includes an address mapping cache that receives an incoming fibre channel frame in a receive and/or transmit segment, wherein the address mapping cache compares a D_ID of an incoming frame in the receive segment and/or a S_ID in the transmit segment; and if a FR_Header is received then a D_ID or S_ID is compared from a fibre channel header that follows the FR_Header; and if a compare fabric identifier flag is set, then the fabric identifier is compared. The address mapping cache may also be used for routing frames from one virtual fabric to another by comparing a VF_ID field to a Virtual fabric identifier in a VFT_Header.

摘要： A method and system for detecting congestion and over-subscription in a fibre channel switch element is provided. A counter is updated if a frame cannot be transmitted due to lack of credit; then the counter value is compared to a threshold value; and an event is triggered if the counter value varies from the threshold value. Also, provided is a first register that maintains information regarding a rate at which a source port can transfer data; a counter that counts entries corresponding to a number of frames to be transmitted at a given time; and a second register that determines an over-subscription rate.

摘要： A fibre channel switch element for routing fibre channel frame is provided. The switch element includes a fibre channel port that can be configured to support plural data transfer rates. The data transfer rate may be 1 G, 2 G, 4 G, 8 G or 10 G. The switch element includes a clock configuration module for providing a clock signal that is based on the data transfer rate. A receive segment of the fibre channel port sends a signal to a transmit segment to avoid an under flow condition. The receive segment also waits for a certain frame length after a fibre channel frame is written and before the fibre channel frame is read, depending upon a data transfer rate of a source port. Multiple lanes may be configured as a single 10 G multi lane port or as multiple individual ports.

摘要： Method and system for processing frames in a fibre channel network is provided. The method includes, determining if an incoming frame in a port of a fibre channel switch includes a FR_Header with a time to live time (“TTLT”) field value; determining if the TTLT field value is greater than a certain number; adjusting the TTLT field value at a pre-determined time interval if the TTLT field value is greater than the certain number; and inserting an adjusted TTLT field value in the incoming frame before it is sent out. The switch element includes, a port that receives an incoming frame and determines if a FR_Header with a time to live time (“TTLT”) field value is received with the FR_Header, and using a timer adjusts the TTLT field value and inserts the adjusted TTLT field value in the incoming frame, before it is sent out.
