Abstract: Techniques allow seamless transitioning of a mesh-based videoconference to a bridged videoconference. Criteria are defined for use in a triggering point function that may be evaluated to determine whether to make the transition. Escalation logic in an escalation manager may be used to manage the transition, allowing some participants to connect via a multipoint control unit, which is in turn a participant in the mesh-based videoconference, with the escalation manager relaying media streams from the mesh-connected participants. The mesh-connected participants may then drop their mesh connections without disruption to the videoconference. Escalation logic in the endpoints may be used as an alternate to an escalation manager unit.

Abstract: The present invention relates to methods and apparatus for buying connectivity. A routing engine may receive a buyer request for a connectivity path wherein the buyer request includes a buyer criteria. The routing engine may identify one or more connectivity paths wherein each identified connectivity path comprises one or more connectivity legs. The routing engine may determine one or more available connectivity paths based on the buyer criteria and the routing engine may select an optimal connectivity path from the determined available connectivity paths.

Abstract: The present invention relates to methods and apparatus for providing a selling mechanism, in particular for connectivity. A trading engine may receive a seller request for a connectivity leg from a seller wherein the seller request includes a seller criteria. A routing engine may identify if the connectivity leg falls within a connectivity path for a buyer. The routing engine may determine if relevant criteria of the seller criteria for the connectivity leg are fulfilled and a reservation component may reserve the connectivity leg for said buyer based if the relevant criteria of the seller criteria are fulfilled.

Abstract: The present invention relates to methods and apparatus for buying connectivity. A routing engine 103 may receive a buyer request for a connectivity path wherein the buyer request includes a buyer criteria. The routing engine 103 may identify one or more connectivity paths wherein each identified connectivity path comprises one or more connectivity legs. The routing engine 103 may determine one or more available connectivity paths based on the buyer criteria and the routing engine 103 may select an optimal connectivity path from the determined available connectivity paths.

Abstract: The present invention relates to methods and apparatus for providing a selling mechanism, in particular for connectivity. A trading engine 102 may receive a seller request for a connectivity leg from a seller wherein the seller request includes a seller criteria. A routing engine 103 may identify if the connectivity leg falls within a connectivity path for a buyer. The routing engine 103 may determine if relevant criteria of the seller criteria for the connectivity leg are fulfilled and a reservation component 107 may reserve the connectivity leg for said buyer based if the relevant criteria of the seller criteria are fulfilled.
