Abstract: A method and apparatus for line card redundancy in a communication switch is presented. The switch includes an arbiter coupled to the input of a switch core and a line card pair. The first line card of the line card pair is considered an active line card, whereas the second line card of the line card pair is considered the redundant, or inactive, line card. The active and inactive line cards are determined based on selection information received by the arbiter. Based on the selection information, the arbiter preferentially provides ingress data from the active line card to the corresponding input of the switch core. A router is coupled to the line card pair and to an output of the switch core. The router passes egress data from the switch core to at least one of the first and second line cards based on routing information included in the egress data.

Abstract: A data traffic management system that has the capability of writing data to the buffer memory at twice its normal rate. The data traffic management system uses a pointer structure that can reference either a single or a dual segment memory bank. A dual segment memory bank enhances the write capability of the data traffic management system by allowing two segments to be simultaneously written to both segment memory banks, with one segment being written to each bank. A pointer data structure with a single/dual indicator (S/D indicator) is used for referencing the memory banks. If the S/D indicator has a D entry, then a dual segment memory bank is addressed. The S/D indicator will have an S entry if a single segment memory bank is addressed. Based on the contents of the S/D indicator, either a single fixed size data segment is written to a single memory bank or two fixed size data segments are written to a dual segment memory bank.

Abstract: Methods and devices for arranging memory access operations to minimize memory bank conflicts between such operations. A fixed pattern of memory access operations is implemented to minimize the effects of a transition between a read memory access operation and a write memory access operation. A write-read-gap (WRG) set pattern of a write memory access operation followed by a read memory access operation and then followed by a set gap when no memory access operation may be undertaken, meets the particular requirements of RDRAM. Within the WRG pattern, read addresses and write addresses are selected to minimize memory bank access conflicts. Such selections are assisted in increasing the efficiency of the memory access operations by defining a set frame size of a specific number of repetitions of the WRG pattern. All memory access operations are then rearranged to conform to the WRG pattern and, the repetitions of the WRG pattern are divided into frames having a size equal to that of the defined frame size.

Abstract: Methods and devices for dividing differently sized data transmission units into fixed sized segments for use with a switch core. Differently sized data transmission units are divided into a number of fixed size segments. Each of the fixed size segments has a segment header section and segment payload section. The segment header section has routing information for the segments and a field for indicating whether the segment payload section is fully occupied or not. The segment payload section carries the actual data from the data transmission unit that has been divided. If the segment payload section is not fully occupied, a field in the payload section indicates how much of the space in the segment payload section is occupied. To track segments from the same data transmission unit the segment header section also has a EOP or end of package field that indicates whether a segment the end of the sequence of segments derived from a single divided data transmission unit.

Abstract: A congestion management system that controls access to any shared resource by incoming data transmission units. The access can be controlled based on the particular connection associated with a data transmission unit. Every shared resource, such as a pool of buffer memory, is represented by a partition. The congestion management system is comprised of a plurality of connection data structures and a plurality of partition data structures. Each connection data structure represents a particular connection and, similarly, each partition data structure represents a particular partition. Each incoming DTU is associated with a single connection but may be allowed access to more than one partition. Each partition is associated with a shared resource and access to each partition is governed by the state of a partition data structure. If a partition data structure indicates that a specific threshold has been met, then access to the shared resource by other DTUs is denied.

Abstract: A method and apparatus for a high bandwidth multi-source interconnection using point-to-point buses that may be utilized in a communication switch is presented. In the communication switch, a number of output buffers are included to correspond to the outputs of the switch. Each output receives data from a number of different inputs to the switch. Each output buffer includes a plurality of queuing elements where each queuing element receives data from at least one of the inputs and buffers the data prior to insertion into an output data stream corresponding to the output of the output buffer. The plurality of queuing of elements are intercoupled in a daisy chain configuration such that a daisy chain output of one queuing element is coupled to the daisy chain input of the succeeding queuing element. The daisy chain configuration provides a data path through which a data stream that becomes the output of the output buffer is carried.

Abstract: The method for servicing queues holding messages, such as ATM data packets, for subsequent processing or transmission to a resource such as a communications link having a finite processing capability comprises the steps of servicing each queue by forwarding the messages thereof to the resource at time intervals corresponding to a guaranteed service rate of the queue, provided the queue is non-empty; and, during time intervals when none of the queues have messages being forwarded to the resource in conformance with the above step, servicing the queues in accordance with a proportion of a remaining or idle resource bandwidth allocated to each queue.
