In one embodiment, a device in a network maintains first and second routing tables associated with a virtual private network (VPN) tunnel. The first and second routing tables comprise routing information used to route packets external to a particular routing domain. The device routes a first packet in the network via the VPN tunnel and a second tunnel that encapsulates the VPN tunnel, using the routing information in the first routing table. The device receives a second packet via the VPN tunnel that was routed to the device using the routing information in the second routing table and bypasses the second tunnel.

Virtual routing and forwarding (VRF) for asymmetrical virtual service provider (VSP) tunnels

In one embodiment, a device in a network identifies a translated source network address for a tunnel source of a tunnel-in-tunnel packet. The device includes the translated source network address within a header of the packet. The header of the packet identifies an inner tunnel that is encapsulated within an outer tunnel during transmission of the packet within the network. The device sends the packet with the translated source network address within the header of the packet.

In one embodiment, the methods and apparatuses detect devices participating in a conference; monitor the devices for an attribute corresponding to an attention level of each of the devices; and determine whether each device is active based on the attention level.

Methods and apparatuses for monitoring attention of a user during a conference

In one embodiment, the methods and apparatuses include requesting an expert during a collaboration session; determining a subject matter of the collaboration session; detecting a potential participant to serve as the expert; and inviting the potential participant to join the collaboration session.

Methods and apparatuses for locating an application during a collaboration session

In one embodiment, the methods and apparatuses view content that corresponds with a particular time period during a collaboration session; identify a plurality of attendee devices participating in the collaboration session at the particular time period; determine an attention status of each attendee device at the particular time period; and display the attention status of the plurality of attendee devices at the particular time period.

Methods and apparatuses for reporting based on attention of a user during a collaboration session

In one embodiment, methods and apparatuses are provided for allowing an invited participant to access a customized web page; programming a first content for the invited participant; displaying the first content on the customized web page to the invited participant; and automatically displaying a second content to the invited participant based on displaying the first content to the invited participant.

Methods and apparatuses for selectively displaying information to an invited participant

The present invention provides a device for feeding pulverized coal to a furnace, such as a drop tube furnace. The feeding system consists of a feed hopper, a pneumatic vibrator positioned on the periphery of the feeder hopper, a needle valve arrangement in the said feed hopper, a depth gauge micrometer, a distribution chamber with primary and secondary airline at the bottom of the said feed hopper. Adjusting the pressure of compressed air allows setting of the frequency of vibration of the pneumatic vibrator. The needle valve arrangement in conjunction with the vibratory hopper controls the feed rate. The rate of coal flow is measured by the depth gauge micrometer. The distribution chamber with primary and secondary airline at the bottom of the said feed hopper allows uniform mixing of air with coal before being charged into the furnace reactor.
