Patent number: 10588044Abstract: A method is provided in one example embodiment and includes receiving a data packet transported on a backhaul link at a first network element; de-capsulating the data packet; identifying whether the data packet is an upstream data packet; identifying whether the data packet matches an internet protocol (IP) access control list (ACL) or a tunnel endpoint identifier; and offloading the data packet from the backhaul link. In more specific embodiment, the method can include identifying that the data packet does not match the IP ACL or the tunnel endpoint identifier; and communicating the data packet to a second network element. In other examples, the method can include identifying that the data packet is a downstream data packet; identifying a service to be performed for the data packet that cannot be performed at the first network element; and communicating the data packet to a second network element.Type: GrantFiled: May 14, 2018Date of Patent: March 10, 2020Assignee: Cisco Technology, Inc.Inventors: Flemming S.

Patent number: 9203755Abstract: A flow of packets sent from a server device over a TCP network to at least one endpoint device is identified, the endpoint device accessing the TCP network over a wireless access network. A message is identified from the endpoint device to the server device communicating an error condition relating to at least one packet in the flow. At least one processing device is used to predict that the error condition is based, at least in part, on a non-congestion-related condition within the wireless access network. The message is filtered to exclude communication of the error condition to the server based on the prediction that the error condition is based, at least in part, on a non-congestion-related condition within the wireless access network. In some aspects, the message can include a TCP duplicate acknowledgement (“DUP ACK”) message.Type: GrantFiled: September 27, 2011Date of Patent: December 1, 2015Assignee: CISCO TECHNOLOGY, INC.Inventors: Chiu Ngok Eric Wong, Jayaraman R.

Patent number: 9049046Abstract: A method is provided in one example embodiment and includes communicating an in-band message packet from a first network element; receiving a response to the in-band message from a second network element, the response contains tunnel identification binding data that identifies a tunnel on a backhaul link on which traffic from a user equipment can flow; and receiving instructions from the second network element to offload a received data packet from the backhaul link. In particular instances, the in-band message is set to loopback when the in-band message is sent from the first network element. In other embodiments, the tunnel identification binding data is provided in the payload of the in-band message when the in-band message is sent from the first network element. In other examples, the method can include receiving an assigned Internet protocol (IP) address of the user equipment in the response to the in-band message.Type: GrantFiled: July 10, 2011Date of Patent: June 2, 2015Assignee: CISCO TECHNOLOGY, INCInventors: Flemming S.

Patent number: 9031038Abstract: A method is provided in one example embodiment and includes receiving a data packet over a first link at a first network element; establishing an out-of-band channel over a second link between the first network element and a second network element; and receiving instructions at the first network element to offload the data packet from the first link. In more particular embodiments, the first network element is a mobile enabled router, and the second network element is a gateway general packet radio service support node or a packet data network gateway. The method can also include receiving a discovery message from the second network element, the discovery message triggering the establishment of the out-of-band channel. In certain cases, the data packet is offloaded based on a type of data in the data packet.Type: GrantFiled: July 10, 2011Date of Patent: May 12, 2015Assignee: Cisco Technology, Inc.Inventors: Flemming S.

Patent number: 9030991Abstract: A method is provided in one example embodiment and includes receiving a downstream data packet transported on a backhaul link at a first network element, the downstream data packet is associated with a user equipment; identifying whether a downstream tunnel used to communicate the data packet to the user equipment has become dormant; and communicating an in-band message to a second network element that the downstream tunnel is dormant. In other examples, the method can include dropping the data packet when a network address port translation binding has expired or does not exist. In certain implementations, the method can include identifying the downstream tunnel as dormant when an activity timer has expired, or identifying the downstream tunnel as dormant based on a stale state setting.Type: GrantFiled: July 10, 2011Date of Patent: May 12, 2015Assignee: Cisco Technology, Inc.Inventors: Flemming S.

Patent number: 8914520Abstract: A method is provided in one example embodiment and includes receiving a request to authenticate an end user in a service provider network, and evaluating the request to identify the end user as belonging to an enterprise network. A tag is generated for a packet associated with a flow for the end user in the enterprise network. Routing occurs for subsequent packets associated with the flow between the enterprise network and the end user. The subsequent packets associated with the flow are not routed through the service provider network. In more particular embodiments, the end user is authenticated in the enterprise network after being authenticated in the service provider network. In addition, traffic for the end user can be separated based on one or more tags identified within the flow. A plurality of flows can be classified based on a customer identification (CID). The tag can be a virtual local area network (VLAN) tag generated at a base station.Type: GrantFiled: November 16, 2009Date of Patent: December 16, 2014Assignee: Cisco Technology, Inc.Inventors: Mark Grayson, Jayaraman R.
