Patent number: 7733905Abstract: A cross-bar switch includes a set of input ports for receiving data packets and a set of sink ports for transmitting the received packets to identified targets. A set of data rings couples the input ports to the sink ports. Each sink port utilizes the set of data rings to simultaneously accept multiple data packets targeted to the same destination—creating a non-blocking cross-bar switch. Sink ports are also each capable of supporting multiple targets—providing the cross-bar switch with implicit multicast capability.Type: GrantFiled: February 1, 2007Date of Patent: June 8, 2010Assignee: Juniper Networks, Inc.Inventors: Abbas Rashid, Nazar Zaidi, Mark Bryers, Fred Gruner

Patent number: 7392369Abstract: Embodiments include various methods, apparatuses, and systems in which a processor includes an out of order issue engine and an in-order execution pipeline. For some embodiments, the issue engine may be remote from the execution pipeline and execution resources may be many clock cycles away from the issue engine. The issue engine categorizes operations as at least one of either a speculative operations which perform computations, or an architectural operations which has potential to fault or cause an exception. Potentially excepting operations may be decomposed into two separate micro-operations: a speculative micro-operation, which is used to generate data results speculatively so that operations dependent on the results may be speculatively issued, and an architectural micro-operation, which signals the faulting condition for the excepting operation. A STORE operation becomes an architectural operation and all previous faulting conditions may be guaranteed to have evaluated before a STORE is issued.Type: GrantFiled: April 18, 2006Date of Patent: June 24, 2008Assignee: Intel CorporationInventors: Jeffery J.

Patent number: 7184446Abstract: A cross-bar switch includes a set of input ports for receiving data packets and a set of sink ports coupled to the input ports to accept and forward the data packets. Each sink port includes a multiple entry point FIFO with multiple data inputs for receiving data packets. In one implementation, the multiple entry point FIFO includes a FIFO storage buffer and request logic coupling the multiple entry point FIFO's data inputs to the FIFO storage buffer. The multiple entry point FIFO concurrently maintains separate pointers into the FIFO storage buffer for each data packet being received on the multiple entry point FIFO's data inputs.Type: GrantFiled: December 21, 2001Date of Patent: February 27, 2007Assignee: Juniper Networks, Inc.Inventors: Abbas Rashid, Nazar Zaidi

Patent number: 7123585Abstract: Each sink port in a cross-bar switch provides for allocating bandwidth among data packets. Packets are assigned priority levels, and the cross-bar switch regulates bandwidth allocation for each priority level. A sink port records traffic volume for packet data of each priority level. The sink port calculates a weighted average bandwidth for each different priority level and determines whether to reject packet data for the priority level. When the packet data collected by a sink port exceeds a threshold, the sink port rejects data packets with priority levels having excessive weighted average bandwidths.Type: GrantFiled: December 21, 2001Date of Patent: October 17, 2006Assignee: Juniper Networks, Inc.Inventors: Abbas Rashid, Nazar Zaidi, Mark Bryers, Fred Gruner

The issue engine categorizes operations as at least one of either a speculative operation which perform computations or an architectural operation which has potential to fault or cause an exception. Each architectural operation issues with an associated architectural micro-operation. A first micro-operation checks whether a first speculative operation is dependent upon an intervening first architectural operation. The in-order execution pipeline executes the speculative operation, the architectural operation, and the associated architectural micro-operations.Type: ApplicationFiled: April 18, 2006Publication date: September 21, 2006Inventors: Jeffery Baxter, Gary Hammond, Nazar Zaidi

Patent number: 7103058Abstract: A cross-bar switch includes a set of input ports for receiving data packets and a set of sink ports for transmitting the received packets to identified targets. A set of data rings couples the input ports to the sink ports. Each sink port utilizes the set of data rings to accept data packets targeted to destinations supported by the sink port. The cross-bar switch includes a multi-sink port for supporting explicit multicast addressing. The multi-sink port is coupled to each data ring and each sink port. The multi-sink port snoops multicast packets on the cross-bar switch's rings and transfers each packet to a set of sink ports that support the packet's targeted destinations.Type: GrantFiled: December 21, 2001Date of Patent: September 5, 2006Assignee: Juniper Networks, Inc.Inventors: Abbas Rashid, Nazar Zaidi, Mark Bryers

Patent number: 7082139Abstract: A cross-bar switch includes a set of input ports to receive data packets and a set of sink ports in communication with the input ports to receive the data packets and forward them onto a communications link. Each sink port is adapted to concurrently receive multiple data packets targeted to the same destination or multiple destinations. For example, one sink port receives a first data packet and a second data packet. The one sink port receives at least a portion of the second data packet during a time period in which the one sink port is receiving the first data packet.Type: GrantFiled: December 21, 2001Date of Patent: July 25, 2006Assignee: Juniper Networks, Inc.Inventors: Abbas Rashid, Nazar Zaidi, Mark Bryers
