Patent number: 9411776Abstract: A method and apparatus for switching a data packet between a source and destination in a network. The data packet includes a header portion and a data portion. The header portion includes routing information for the data packet. The method includes defining a data path in the router comprising a path through the router along which the data portion of the data packet travels and defining a control path comprising a path through the router along which routing information from the header portion travels. The method includes separating the data path and control path in the router such that the routing information can be separated from the data portion allowing for the separate processing of each in the router. The data portion can be stored in a global memory while routing decisions are made on the routing information in the control path.Type: GrantFiled: February 27, 2014Date of Patent: August 9, 2016Assignee: Juniper Networks, Inc.Inventors: Pradeep S. Sindhu, Kireeti Kompella, Dennis C. Ferguson, Bjorn O. Liencres, Nalini Agarwal, Hann-Hwan Ju, Raymond Marcelino Manese Lim, Rasoul Mirzazadeh Oskouy, Sreeram Veeragandham

Patent number: 8761180Abstract: A router for switching data packets from a source to a destination in a network in which the router includes a distributed memory. The distributed memory includes two or more memory banks. Each memory bank is used for storing uniform portions of a data packet received from a source and linking information for each data packet to allow for the extraction of the uniform portions of a data packet from distributed locations in memory in proper order after a routing determination has been made by the router.Type: GrantFiled: March 20, 2013Date of Patent: June 24, 2014Assignee: Juniper Networks, Inc.Inventors: Pradeep Sindhu, Dennis Ferguson, Bjorn Liencres, Nalini Agarwal, Hann-Hwan Ju, Raymond Marcelino Manese Lim, Rasoul Mirzazadeh Oskouy, Sreeram Veeragandham

Patent number: 7903659Abstract: A network device switches variable length data units from a source to a destination in a network. An input port receives the variable length data unit and a divider divides the variable length data unit into uniform length data units for temporary storage in the network device. A distributed memory includes a plurality of physically separated memory banks addressable using a single virtual address space and an input switch streams the uniform length data units across the memory banks based on the virtual address space. The network device further includes an output switch for extracting the uniform length data units from the distributed memory by using addresses of the uniform length data units within the virtual address space. The output switch reassembles the uniform length data units to reconstruct the variable length data unit. An output port receives the variable length data unit and transfers the variable length data unit to the destination.Type: GrantFiled: May 4, 2009Date of Patent: March 8, 2011Assignee: Juniper Networks, Inc.Inventors: Pradeep S.
