Patent number: 9300563Abstract: In one embodiment, a plurality of links between a network node and another network node are configured as a link bundle. The network node establishes one or more standby bidirectional forwarding detection (BFD) sessions. Each standby BFD session is associated with one or more links of the link bundle. The network node establishes an active BFD session. The active BFD session is associated with one or more links of the link bundle. In response to non-receipt of returned BFD messages for the active BFD session, one or more new active BFD sessions are selected from the one or more standby BFD sessions. In response to non-receipt of returned BFD messages for the one or more new active BFD sessions, it is determined that the link bundle has failed.Type: GrantFiled: September 16, 2013Date of Patent: March 29, 2016Assignee: Cisco Technology, Inc.Inventors: Reshad A.

Patent number: 9166877Abstract: In one embodiment, a local network device transmits a connectivity verification protocol control message over a link to a remote network device to attempt to establish a connectivity verification protocol session with the remote network device. In response to non-receipt of a returned connectivity verification protocol control message from the remote network device, the local network device determines that there is an inability to establish a connectivity verification protocol session with the remote network device. The local network device then sends a connectivity verification protocol echo message over the link to the remote network device without establishment of a connectivity verification protocol session. The echo message is sent using a forwarding protocol.Type: GrantFiled: April 12, 2013Date of Patent: October 20, 2015Assignee: Cisco Technology, Inc.Inventors: Reshad A. Rahman, David P.

Publication number: 20150085860Abstract: In one embodiment, a connectivity verification protocol (CVP) session for a particular virtual interface (VI) may operate on a particular group of two or more line cards (LCs) on a network device. The group of LCs may then transmit CVP session packets, at a reduced rate that is sufficient to maintain the CVP session based on a negotiated CVP full rate, onto the particular VI through ingress path processing on the network device. Ingress path processing, in particular, takes transmitted CVP session packets and egresses them onto an appropriate LC of the network device currently responsible for the VI egress. Also, in response to receiving CVP session packets for the VI on an LC of the network device currently responsible for the VI ingress, the receiving LC may forward the received CVP session packets to the particular corresponding group of LCs, which may then process the received CVP session packets.Type: ApplicationFiled: September 29, 2014Publication date: March 26, 2015Inventors: Sami Boutros, Sylvain Masse, Clarence Filsfils

Patent number: 8543718Abstract: A technique efficiently and dynamically maintains bidirectional forwarding detection (BFD) on a bundle of links in a computer network. According to the novel technique, one or more “standby” BFD sessions may be established on one or more corresponding line cards (LCs), the LCs having one or more links of the bundle (bundle links). Once established, one of the standby BFD sessions may be selected as an “active” BFD session based on activity of one of the bundle links of the corresponding LC. Also, BFD messages may be transmitted from one of the bundle links of the active BFD session, e.g., the link receiving BFD messages. In response to inactivity of the transmitting link (e.g., failure, removal, etc.), the active BFD session may switch to another available active bundle link, and if no other active bundle links are available to the active BFD session, one of the standby BFD sessions is selected as the new active BFD session.Type: GrantFiled: March 2, 2006Date of Patent: September 24, 2013Assignee: Cisco Technology, Inc.Inventors: Reshad A.

Patent number: 8437272Abstract: In one embodiment, a local network device may determine an inability to establish a connectivity verification protocol (e.g., Bidirectional Forwarding Detection, “BFD”) session to a remote network device, such as from unreturned control messages. In response, the local network device may send at least one connectivity verification protocol echo message to the remote network device destined to be returned to the local network device and forwarded using a forwarding protocol. In response to receiving or not receiving the echo message, the local network device may thus determine whether the forwarding protocol is functioning between the local and remote network devices. In this manner, the local network device may determine whether an inability to establish a connectivity verification protocol session is due to an inability to forward packets between the devices, or due to the connectivity verification protocol not working (or not being configured) on the remote network device.Type: GrantFiled: August 16, 2007Date of Patent: May 7, 2013Assignee: Cisco Technology, Inc.Inventors: Reshad A.

Publication number: 20040116938Abstract: A medical assembly for introducing an expansible prosthesis in a bodily duct includes a tubular sheath opened at a distal end, an elongated element disposed substantially at the centre of the sheath and letting an intermediate radial space between the elongated element and the sheath, and a pusher movable in said tubular sheath. The expansible prosthesis is introduced in the bodily duct by moving between a first holding position in which the prosthesis is at least substantially applied against an internal wall of the sheath, and a second expanded position in which the prosthesis is applied against an internal wall of the bodily duct, the expansible prosthesis passing through intermediate positions in which a proximal portion is inside the sheath and a distal portion is outside the sheath.Type: ApplicationFiled: August 11, 2003Publication date: June 17, 2004Inventors: Simon John Forber, Sylvain Masse, Damien Sandoz-Othenin
