Patent number: 7016956Abstract: Tailored application or service may be delivered via a communication device to a number of subscribers in a manner that avoids having to store individual copies of a service profile on the device for each subscriber receiving the application or service. Specifically, a packet is received requesting delivery of the application or service from the subscriber at a communication device. In response, the communication device retrieves a subscriber context, which references policies that describe each of the applications and services available to the subscriber. The application or service requested by the packet is compared with the policies referenced by the subscriber context to identify any matching policies. Subsequently, the requested application or service is delivered to the subscriber via the communication device according to the matching policies as described by a service profile. This service profile is accessible for describing the application or service when requested by other subscribers.Type: GrantFiled: July 31, 2001Date of Patent: March 21, 2006Assignee: Ellacoya Networks, Inc.Inventors: Kurt A. Dobbins, David J. Ruffen, Brett A. Miller, Bruce E. Caram

Publication number: 20050005023Abstract: Methods and systems for providing scaleable flow based application control in private and public Internet. A flow table can be used to control the application and subscriber traffic for communication flows in access networks. The flow table entry can provide granular, unidirectional packet transmission of data for all or a subset of all host and application communications originating from or destined to network hosts in the access network. Using a flow table entry for multiple unidirectional packet transmissions of data provides efficient use of flow table entries and allows varying operator control of application communication exchanges between network hosts and applications. By using variable masking techniques, the flow table can be used for varying degrees of control over the packet transmissions in the network.Type: ApplicationFiled: September 30, 2003Publication date: January 6, 2005Inventors: Kurt Dobbins, Brett Miller, Bruce Caram

Patent number: 6618762Abstract: An apparatus and method for allocating the performance of applications in a networking chassis among one or more modules in the chassis. In particular, the system acts as a chassis agent for performing network management functions. The agent performs a discovery function whereby each module discovers the location and current utilization of resources and applications for itself and transmits that information to other modules, and wherein each module maintains a slot table of such information for all modules. Based on the information in the slot table, each module performs an election function for allocating applications among the various modules in the chassis. The agent uses MIBs to gather information about the chassis and to effect control on the chassis, wherein each managed object is registered both locally and remotely in a MIB tree maintained on each module, and the data is maintained locally on the module on which the managed object resides.Type: GrantFiled: May 9, 2002Date of Patent: September 9, 2003Assignee: Enterasys Networkds, Inc.Inventors: Brendan Fee, Kurt Dobbins, Dave Arneson, Pat Mullaney

Publication number: 20020029288Abstract: Apparatus and method wherein multiple router interfaces are assigned the same IP network address, creating an IP work group. This enhances host mobility by allowing, in one embodiment, a host to be relocated anywhere in the work group without requiring reconfiguration of the host. As a further option, host address ranges may be specified (i.e., locked) to designated interfaces of the work group, to enhance security by restricting the allowed host mobility within the work group. An additional advantage is a reduced consumption of network and subnet addresses, because now a single address is used for several physical networks.Type: ApplicationFiled: June 15, 2001Publication date: March 7, 2002Inventors: Kurt A.

Patent number: 6147995Abstract: Method and apparatus for establishing restricted broadcast groups in a switched network. The method assigns different virtual LAN identifiers (VLAN-IDs) to different subsets of associated end systems or access ports. Tables are maintained for mapping the VLAN-IDs with associated end systems and access ports. When a broadcast packet is received at a first switch, it is encapsulated with a VLAN header, including the VLAN-IDs, and sent out a multicast channel to all other switches in the network (domain). The original packet is sent out the other access ports of the receiving switch for the designated VLAN-IDs. The switches receiving the VLAN packet remove the header and send the original packet out access ports associated with the VLAN-IDs extracted from the header. The method provides a mechanism for forwarding broadcast packets of a protocol not supported by the switching mechanism, as well as multicast packets and unicast packets from undiscovered end systems.Type: GrantFiled: August 31, 1999Date of Patent: November 14, 2000Assignee: Cabletron Systems, Inc.Inventors: Kurt Dobbins, Phil Andlauer, Michael Skubisz

Patent number: 5951649Abstract: An interconnecting apparatus includes one or more interfaces. Each interface connects to a network. The interconnecting apparatus interconnects the networks attached to the interfaces. The device utilizes distributed autonomous forwarding engines on each interface in that each interface has a forwarding engine corresponding to it. Each forwarding engine only knows the configuration information and how to receive and transmit packets on the one interface to which it corresponds. Each forwarding engine acts independently to process packets, yet each interacts together to collectively provide packet forwarding which is protocol independent, interface independent, and scalable.Type: GrantFiled: March 8, 1996Date of Patent: September 14, 1999Assignee: Cabletron Systems, Inc.Inventors: Kurt Dobbins, Kris Dobbins, Len Cormier, Kevin Yohe, William Haggerty, Paul Simoneau, Rich Soczewinski
