US Patent:
6842462, Jan 11, 2005
Filed:
Dec 17, 1999
Appl. No.:
09/466485
Inventors:
Ramachandran Ramjee - Matawan NJ, US
Thomas F. La Porta - Thornwood NY, US
Kannan Varadhan - Woodbridge NJ, US
Luca Salgarelli - Middletown NJ, US
Mark Haner - Westfield NJ, US
Arun Narayan Netravali - Westfield NJ, US
Gerard Terence Foster - Swindon, GB
Assignee:
Lucent Technologies Inc. - Murray Hill NJ
International Classification:
H04J 316
US Classification:
370466, 370328, 370338, 370352, 37039552, 370401, 455433, 455435
Abstract:
A General Packet Radio Service (GPRS) Accessed Extended Mobile Internet Protocol (EMIP) [G-EMIP] network is provided for wireless mobile device access to external packet data networks. Domains are defined to incorporate a subnet of standard GPRS and EMIP network entities accessed through a Domain Router. Packet access at the radio interface is provided using the base station portion of a GPRS network. Wireless link specific processing is relegated to this potion of the G-EMIP network. EMIP is utilized as a backbone network to provide mobility and service management and interconnection to external networks. A GPRS-IP Interworking entity (GII) interworks IP and GPRS protocols between GPRS and IP addressable network entities (i. e. , translates messages of each protocol to corresponding messages of the other protocol). Mobility-related functionality is handled at the IP (network) layer.

Transient Tunneling For Dynamic Home Addressing On Mobile Hosts

View page
US Patent:
7554967, Jun 30, 2009
Filed:
Sep 15, 2000
Appl. No.:
09/662531
Inventors:
Kannan Varadhan - Santa Clara CA, US
Thomas F La Porta - Holmdel NJ, US
Ramachandran Ramjee - Matawan NJ, US
Luca Salgarelli - Hoboken NJ, US
Sandra R Thuel - Middletown NJ, US
Assignee:
Alcatel-Lucent USA Inc. - Murray Hill NJ
International Classification:
H04L 12/28
US Classification:
370352, 370392
Abstract:
Portable and/or mobile IP hosts desiring to connect to the Internet can dynamically acquire a home address and other configuration information through DHCP when powering up in a foreign network. A two-stage configuration procedure is used. First, the mobile host uses the M-IP protocol to establish contact with an addressing element, referred to as a bootstrapping agent, that is usually co-located with a M-IP Home Agent, and that allocates a temporary home address for the mobile host. The temporary address is used to create a temporary tunnel. Second, this temporary tunnel is used as the communication vehicle over which standard DHCP transactions take place. The present invention is thus arranged to use a) M-IP as the signaling mechanism for reaching the home network and dynamically allocating a temporary home address for the mobile host; and b) DHCP to allocate a permanent home address and any other configuration state for the mobile host.

Applying Services Within Mpls Networks

View page
US Patent:
7948986, May 24, 2011
Filed:
Feb 25, 2009
Appl. No.:
12/392740
Inventors:
Kaushik Ghosh - Sunnyvale CA, US
Kireeti Kompella - Los Altos CA, US
Kannan Varadhan - San Jose CA, US
Assignee:
Juniper Networks, Inc. - Sunnyvale CA
International Classification:
H04L 12/56
US Classification:
370392, 370401
Abstract:
In general, techniques are described that facilitate application of service within MPLS networks. More specifically, a router comprises a forwarding plane, a service plane and a routing engine. The routing engine maintains data defining an association between a handle identifying a property common to a plurality of packets of a particular context and one or more MPLS labels associated with these packets. The routing engine automatically generates and installs a filter to identify these packets within both the forwarding and service planes. The forwarding plane applies the filter to incoming packets to determine whether each of the incoming packets includes a label matching any of the labels of the filter and forwards the incoming packets to the service plane upon a match. The service card selects one or more services identified by the filter and applies the selected one or more services to the incoming packet.

International Classification:
H04L 12/26
H04L 12/56
US Classification:
370235, 370392
Abstract:
A method may include receiving a packet at an ingress line interface in a forwarding plane of a network element, the packet including header information. The method may also include conducting a flow table lookup in the forwarding plane to identify an existing flow for the packet and determining, in the forwarding plane and based on the header information, whether a predicted flow can be identified for the packet if an existing flow can not be identified. The method may further include performing a service access control list (ACL) lookup in the forwarding plane if a predicted flow can not be identified; and forwarding the packet to one of a services plane or an egress line interface in the forwarding plane based on one of the existing flow, the predicted flow, or the service ACL lookup.

Routing Device Having Integrated Mpls-Aware Firewall

US Patent:
8307422, Nov 6, 2012
Filed:
Nov 14, 2008
Appl. No.:
12/271605
Inventors:
Kannan Varadhan - San Jose CA, US
Joao Campelo F. N. Gomes - Bristol, GB
Assignee:
Juniper Networks, Inc. - Sunnyvale CA
International Classification:
G06F 15/16
US Classification:
726 15, 726 22, 713151
Abstract:
An MPLS-aware firewall allows firewall security policies to be applied to MPLS traffic. The firewall, which may be integrated within a routing device, can be configured into multiple virtual security systems. The routing device provides a user interface by which a user specifies one or more zones to be recognized by the integrated firewall when applying stateful firewall services to the packets. The user interface allows the user to define different zones and policies for different ones of the virtual security systems. In addition, the user interface supports a syntax that allows the user to define the zones for the firewall by specifying the customer VPNs as interfaces associated with the zones. The routing device generates mapping information for the integrated firewall to map the customer VPNs to specific MPLS labels for the MPLS tunnels carrying the customer's traffic.

US Patent:
8510551, Aug 13, 2013
Filed:
Nov 10, 2008
Appl. No.:
12/267938
Inventors:
Purvi Desai - Cupertino CA, US
Kannan Varadhan - San Jose CA, US
Assignee:
Juniper Networks, Inc. - Sunnyvale CA
International Classification:
H04L 29/06
US Classification:
713163, 713150, 713152, 713160, 713162, 726 1, 726 3, 709224, 709227, 709228, 709229, 709232
Abstract:
A device, receives a unicast packet designating a unicast source and a unicast destination, and determines whether the received unicast packet is a Data Register message. The device extracts information relating to a multicast packet encapsulated within the unicast packet when the unicast packet is a Data Register message, and performs a security policy lookup based on the extracted multicast packet information to identify a security policy associated with the multicast packet. The device determines whether the identified security policy authorizes forwarding of the unicast packet, and establishes a multicast data session when the identified security policy authorizes forwarding of the unicast packet. The device establishes a multicast control session based on the multicast data session, where the multicast control session authorizes transmission of PIM-related control messages associated with the multicast packet. The device forwards the unicast packet to the unicast destination based on the multicast data session.
