Patent number: 8903955Abstract: Network operators are striving to find ways to provide stable video services amid a rapid increase in video data traffic. In order to provide stable video services with constrained network resources, network operators attempted to reduce video file sizes and to cache videos for future use. However, network operators failed to exploit user information and to leverage benefits of distributing these functionalities across the network. This disclosure provides systems and methods for efficiently delivering video and managing video caches by exploiting user information and by distributing video delivery functionalities across the network.Type: GrantFiled: December 2, 2011Date of Patent: December 2, 2014Assignee: Cisco Technology, Inc.Inventors: Vivek Kansal, Timothy Stammers, Bhaskar Bhupalam, Biswaranjan Panda, Jayaraman Iyer

Patent number: 8787303Abstract: This disclosure relates to a system and method for offloading selected data traffic in logical tunnels to the Internet. The offloading provides another data path for selected data traffic that can relieve the burden on a mobile operator's network, such as the backhaul and core networks. As the proliferation of data rich content and increasingly more capable mobile devices has continued, the amount of data communicated over mobile operator's networks has increased. Upgrading the existing network that was designed for voice calls is not desirable or practical for many mobile operators. This disclosure provides systems and methods for offloading data to the Internet at a router to relieve congestion on the mobile operator's network.Type: GrantFiled: May 20, 2011Date of Patent: July 22, 2014Assignee: Cisco Technology, Inc.Inventors: Kent K. Leung, Jayaraman Iyer, Flemming Andreasen, Timothy Stammers, Michel Khouderchah

Patent number: 8780909Abstract: Systems and methods for modifying a media protocol based on subscriber and network performance information is disclosed. Media protocols such as adaptive bitrate protocol can adjust bit rates based on conditions perceived at the mobile device and with a goal of obtaining the highest bit rate possible. The media protocols residing on the mobile device do not have access to network performance information that can change rapidly and impact the experience at the mobile device. For example, congestion, radio air link interference, handoffs, and quality of service parameters can all impact the experience a user has when accessing media files from a mobile device. The requests made by a mobile device can be modified to take into account these factors to enhance the user experience.Type: GrantFiled: March 21, 2012Date of Patent: July 15, 2014Assignee: Cisco Technology, Inc.Inventors: Kevin Shatzkamer, Richard Christopher Hayes, Mark Grayson, Jayaraman Iyer, Timothy Stammers

Patent number: 8391153Abstract: Particular embodiments provide an access gateway that facilitates communication between a plurality of access technologies. The access gateway facilitates data communication with an access terminal through a bearer path. A radio resource manager is configured to provide radio resource management functions for the communications. The radio resource manager is decoupled from the bearer path and provides control of radio transmission characteristics for the bearer path to the gateway. Because the radio resource manager is not in the bearer path, the access gateway may be access technology agnostic. Thus, the access gateway does not need to have access-specific modules based on the radio technology for each bearer path.Type: GrantFiled: February 16, 2007Date of Patent: March 5, 2013Assignee: Cisco Technology, Inc.Inventors: Anand K. Oswal, Timothy Stammers, Jayaraman Iyer, Parviz Yegani

Patent number: 8233401Abstract: In one embodiment, a network device receives an Internet protocol (IP) registration request, such as a mobile IP registration request, from an access terminal. The network device may be a home agent that is configured to register the access terminal for IP services at the network layer. In addition to registering the access terminal at the network layer, the network device may facilitate registration at another layer, such as the application layer. In one example, registration information for the access terminal for an application layer registration, such as information needed to register for a session initiation protocol (SIP) services, is determined. The network device then facilitates registration at the application layer automatically using the registration information.Type: GrantFiled: August 13, 2007Date of Patent: July 31, 2012Assignee: Cisco Technology, Inc.Inventors: Jonathan D. Rosenberg, Flemming Andreasen, Jayaraman Iyer, Timothy Stammers

Publication number: 20120082073Abstract: A method is provided in one example embodiment and includes receiving a data packet transported on a backhaul link at a first network element; 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; performing a network address translation on the data packet; and offloading the data packet from the backhaul link. In certain implementations, 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 instances, the method can include identifying that the data packet is a downstream data packet; and restoring a tunnel header and tunnel identification based on an IP address of the data packet.Type: ApplicationFiled: July 10, 2011Publication date: April 5, 2012Inventors: Flemming S.
