Patent number: 7512065Abstract: Setting up a group of virtual circuits using a single set up message request. In an embodiment, fewer than all of the virtual circuits in the group are immediately provisioned, and the remaining virtual circuits are placed in an inactive status by appropriate configuration of all the devices in the path of the group of virtual circuits. Each of the inactive virtual circuits can be activated (complete provisioning) as and when required. The bandwidth overhead on the networks is reduced as fewer signaling messages would be used in provisioning several virtual circuits. The parsing overhead is reduced on the devices processing the signaling messages as a result.Type: GrantFiled: October 15, 2001Date of Patent: March 31, 2009Assignee: Cisco Technology, Inc.Inventors: Amit S.

Patent number: 7480732Abstract: A switch may be configured to support a point-to-multi-point PVC which can be used to support a point to multi-point application. The signaling overhead is reduced due to the use of PVC, and the available bandwidth is used efficiently due to the use of the point-to-multi-point connection. Another aspect of the present invention minimizes the resources required while providing such point-to-multi-point virtual connections. A switch may minimize allocation of resources to branches that are not active. For example, a switch may determine that a branch is inactive based on the absence of reception of OAM cells in a specified duration and delete the forwarding information for the inactive branch. The switch may thus scale to support many point-to-multi-point virtual circuits having many branches.Type: GrantFiled: April 22, 2002Date of Patent: January 20, 2009Assignee: Cisco Technology, Inc.Inventors: Pankaj Vyas, Balaji Lakshmikanth Bangolae, Amit S.

Patent number: 7068645Abstract: A network device (e.g., network access server or home gateway) providing different QOS (quality of services) to different layer-3 datagrams when transporting on tunnels. A tunnel may be implemented to provide different QOS to different packets depending on the packet header. The network device examines the header of each datagram to determine the specific QOS to be provided. At least the data portion in the datagram is encapsulated for transportation on the tunnel. The encapsulated data portion in turn is encapsulated in the form of one or more packets, with the packet format to reflect the QOS determined for the datagram. When the tunnel is implemented on UDP/IP and the datagram is an IP (Internet protocol) datagram, the TOS/Precedence bits of the IP datagram may be copied into the precedence/TOS bits of the UDP/IP packet(s).Type: GrantFiled: April 2, 2001Date of Patent: June 27, 2006Assignee: Cisco Technology, Inc.Inventors: Amit Phadnis, Pankaj Vyas, Praneet Bachheti

Patent number: 6981064Abstract: Data related to multiple point-to-point sessions is transmitted on a single virtual circuit of a ATM based network. In an embodiment implemented in accordance with ATM Adaptation Layer 2 (AAL2), the data related to each session is transported on a channel of the AAL2 virtual circuit. As the intermediate devices in the virtual circuit path merely need to maintain tables for one virtual circuit, the overhead on the devices may be minimized. By assigning data of a session to a channel provided by an adaptation layer, addition fields or higher level protocols may not be needed to transport the data related to the sessions.Type: GrantFiled: February 15, 2001Date of Patent: December 27, 2005Assignee: Cisco Technology, IncInventors: Amit Phadnis, Pankaj Vyas

Patent number: 6925081Abstract: A MPLS device which receives configuration data identifying a group of multi-labeled packets and desired EXP (corresponding to the 3-bit experimental bit field specified by MPLS protocol) bits (even in the lower label entries of the label stack) for the group when forwarding the related packets. The MPLS device sets the EXP bits of even such lower label entries, and then forwards the multi-labeled packets. MPLS devices further down the path may provide different services for different multi-labeled packets depending on the EXP bit values. A service provider may configure a autonomous system border router (ASBR) to control service levels for while packets are forwarded further down the path (even in autonomous systems not related to the service provider) according to an aspect of the present invention.Type: GrantFiled: July 11, 2003Date of Patent: August 2, 2005Assignee: Cisco Technology, Inc.Inventor: Sreenath GovindaRaju Meda

Patent number: 6901079Abstract: An aggregation device providing different QOS to different point-to-point sessions. Multiple virtual circuits, each to provide different QOS, may be provisioned. The aggregation device may be configured to indicate the desired QOS for each point-to-point session and the data related to each point-to-point session may be assigned to a virtual circuit providing the closest matching QOS. Alternatively, a service provider may statically specify the specific virtual circuit on which the data related to a specific point-to-point session is to be transmitted. Each point-to-point session receives a QOS provided by the assigned virtual circuit. As the content of each datagram received on a point-to-point session may not need to be examined for the purpose of assignment to a virtual circuit, an aggregation device may forward datagrams quickly.Type: GrantFiled: April 19, 2001Date of Patent: May 31, 2005Assignee: Cisco Technology, IncInventors: Amit Phadnis, Pankaj Vyas, Praneet Bachheti
