Patent number: 11398991Abstract: In some embodiments, an apparatus includes a switch fabric having at least a first switch stage and a second switch stage, an edge device operatively coupled to the switch fabric and a management module. The edge device is configured to send a first portion of a data stream to the switch fabric such that the first portion of the data stream is received at a queue of the second switch stage of the switch fabric via the first switch stage of the switch fabric. The management module is configured to send a flow control signal configured to trigger the edge device to suspend transmission of a second portion of the data stream when a congestion level of the queue of the second switch stage of the switch fabric satisfies a condition in response to the first portion of the data stream being received at the queue.Type: GrantFiled: January 31, 2020Date of Patent: July 26, 2022Assignee: Juniper Networks, Inc.Inventors: Gunes Aybay, Jaya Bandyopadhyay, Srinivas Gadgil

Patent number: 8804711Abstract: In some embodiments, an apparatus includes a first housing, a second housing and at least one cable. The first housing includes a first interface card of a switch fabric. The second housing includes a second interface card of the switch fabric and a third interface card of the switch fabric. The second interface card of the switch fabric is operatively and physically coupled to the third interface card of the switch fabric via a midplane. The second interface card defines a plane that is nonparallel to the a plane defined by the third interface card and a plane defined by the midplane. The plane defined by the third interface card is nonparallel to the plane defined by the second interface card and the plane defined by the midplane. The cable is configured to operatively couple the first interface card to the second interface card.Type: GrantFiled: December 29, 2008Date of Patent: August 12, 2014Assignee: Juniper Networks, Inc.Inventors: Gunes Aybay, Jaya Bandyopadhyay, Jean-Marc Frailong, Pradeep Sindhu, Philip A.

Patent number: 8675483Abstract: A network device includes a group of high speed redundant transmission lines and a switch. The switch is configured to select one of the high speed redundant transmission lines. The switch causes reflections and frequency dependent dispersions in the selected high speed redundant transmission line. The network device further includes a transmitting device that is configured to adjust signals transmitted over the selected high speed redundant transmission line so as to reduce the reflections and frequency dependent dispersions.Type: GrantFiled: March 8, 2011Date of Patent: March 18, 2014Assignee: Juniper Networks, Inc.Inventors: David Chengson, Jaya Bandyopadhyay

Patent number: 8578191Abstract: In one embodiment, a method includes accessing a first utilization value, accessing a second utilization value, defining a third utilization value, and sending to a first switching portion of a distributed network switch a deactivate signal in response to the third utilization value. The first utilization value is associated with the first switching portion of the distributed network switch. The second utilization value is associated with a second switching portion of the distributed network switch. The third utilization value is associated with the second switching portion of the distributed network switch and is based on the first utilization parameter and the second utilization parameter. The first switching portion of the distributed network switch ceases communication within the distributed network switch in response to the deactivate signal.Type: GrantFiled: June 10, 2010Date of Patent: November 5, 2013Assignee: Juniper Networks, Inc.Inventors: Gunes Aybay, Jaya Bandyopadhyay
