Patent number: 10292066Abstract: This disclosure relates to a system and method for modifying selected network congestion control parameters using mobile system information. The congestion control modification improves network performance between a remote server on the Internet and a mobile device. As the proliferation of data-rich content and increasingly more capable mobile devices has continued, mobile consumers increasingly demand better network performance from their mobile devices and mobile infrastructure. This disclosure provides systems and methods for using mobile system information related to Quality of Service guarantees to modify network congestion control.Type: GrantFiled: November 4, 2011Date of Patent: May 14, 2019Assignee: Cisco Technology, Inc.Inventors: Venkateshwara Sastry, Pandurangan R. Sankarlal, Krishna P. Komarath, Navjyot Ramteke

Patent number: 9439075Abstract: In one embodiment, during an authentication process between a network device and an access terminal, an authentication message for access to the network is received. The network device is configured to allow access to an IP network. The network device determines one or more capabilities of the access terminal from the authentication message. An action is then performed based on the one or more capabilities of the access terminal. The action may include using the capabilities to set up a session with the access terminal. Also, the network device may send its own capabilities to the access terminal in an authentication response. Accordingly, a capability negotiation between the access terminal and network device may be provided during an authentication process. This may facilitate a faster session setup as capabilities are exchanged during authentication can be used in the configuration of the session.Type: GrantFiled: May 27, 2015Date of Patent: September 6, 2016Assignee: CISCO TECHNOLOGY, INC.Inventors: Parviz Yegani, Jayaraman Iyer, Venkateshwara Sastry

Publication number: 20150067832Abstract: In one implementation, a phishing scam involves a communication sent to a user by an impersonator. Rather than detect the communication and verify the identity of the sender, the data entry of the user is monitored. For example, an example embodiment scans data entry from a user for a security word and queries a list of authorized terms for the security word. In response to the security word being included in the list of authorized terms, a destination address associated with the security word is identified. A list of authorized destination addresses is queried with the destination address associated with the security word.Type: ApplicationFiled: August 30, 2013Publication date: March 5, 2015Applicant: Cisco Technology, Inc.Inventor: Venkateshwara Sastry

Patent number: 8351928Abstract: Synchronizing mobility messaging includes receiving an Internet Protocol (IP) address at a Dynamic Host Configuration Protocol (DHCP) server. The IP address is sent by a home agent of a mobile client, where the home agent has a mobility binding for the mobile client. A DHCP request requesting an IP address for the mobile client is received from the mobile client. The DHCP server assigns the IP address to the mobile client. A DHCP acknowledgement comprising the assigned IP address is sent to the mobile client.Type: GrantFiled: April 14, 2008Date of Patent: January 8, 2013Assignee: Cisco Technology, Inc.Inventors: Venkateshwara Sastry, Anand Oswal, Jayaraman R.

Patent number: 7813316Abstract: In one embodiment, mobile nodes may be pre-provisioned with a static home agent address and a static home address. The home agent address may be the same for all the mobile nodes. The home address may be a unique identifier for the mobile node in a network. A registration request from a mobile node may be sent to the home agent address. A load balancer may be configured to receive the registration request at the home agent address. The load balancer is then configured to determine a home agent in the plurality of home agents to send the registration request to. The load balancer determines which home agent to send the request to based on the home address for the mobile node. The load balancer then sends the request to the determined home agent.Type: GrantFiled: June 26, 2007Date of Patent: October 12, 2010Assignee: Cisco Technology, Inc.Inventor: Venkateshwara Sastry

Patent number: 7778220Abstract: The invention relates to load balancing the binding creation on a home agent with a mobile node in an IPV6 network. A home agent serving a prefix learns about load on other home agents and when a home agent address discovery request from a mobile is received by a home agent, the home agent processing the message returns addresses of the least loaded home agent to the mobile node.Type: GrantFiled: November 6, 2006Date of Patent: August 17, 2010Assignee: Cisco Technology, Inc.Inventor: Venkateshwara Sastry
