Patent number: 8571024Abstract: An architecture for a line card in a network routing device is provided. The line card architecture provides a bi-directional interface between the routing device and a network, both receiving packets from the network and transmitting the packets to the network through one or more connecting ports. In both the receive and transmit path, packets processing and routing in a multi-stage, parallel pipeline that can operate on several packets at the same time to determine each packet's routing destination is provided. Once a routing destination determination is made, the line card architecture provides for each received packet to be modified to contain new routing information and additional header data to facilitate packet transmission through the switching fabric. The line card architecture further provides for the use of bandwidth management techniques in order to buffer and enqueue each packet for transmission through the switching fabric to a corresponding destination port.Type: GrantFiled: November 23, 2010Date of Patent: October 29, 2013Assignee: Cisco Technology, Inc.Inventors: Mohammed I. Tatar, Garry P. Epps, Oded Trainin, Eyal Oren, Cedrik Begin

In both the receive and transmit path, packets processing and routing in a multi-stage, parallel pipeline that can operate on several packets at the same time to determine each packet's routing destination is provided. The transmit path of the line card architecture further incorporates additional features for treatment and replication of multicast packets. These features can include a recycle path coupling a gather stage circuit and a fetch stage circuit and can include sequence number logic configured to associate sequence numbers with multicast packet headers.Type: GrantFiled: March 1, 2006Date of Patent: June 1, 2010Assignee: Cisco Technology, Inc.Inventors: Mohammed I.

Patent number: 7715419Abstract: An architecture for a line card in a network routing device is provided. The line card architecture provides a bi-directional interface between the routing device and a network, both receiving packets from the network and transmitting the packets to the network through one or more connecting ports of a network interface. A high priority buffer and a low priority buffer can be assigned to each port of the network interface. The network interface can perform packet prioritization through buffer selection based on priority. High priority packets will be transmitted to an ingress packet processor before low priority packets for a given port.Type: GrantFiled: March 6, 2006Date of Patent: May 11, 2010Assignee: Cisco Technology, Inc.Inventors: Mohammed I.
