Abstract: A method and apparatus for dynamic routing of wireless communications. More particularly, wireless communications are dynamically routed by marking, by a softswitch, every endpoint participating in a call and as the entry for a marked endpoint is updated a message is generated and sent to the softswitch. Upon receiving such a message, the softswitch re-computes the necessary new resources for maintaining the call and (i) instructs such new resources to negotiate media transfer, (ii) after receiving an acknowledgement from the new resources, transmits appropriate call initiation messages to such resources; and (iii) transmits call release messages to the prior, i.e., old, resources supporting the call. Advantageously, selection of the requisite resources to participate in a particular is driven by the knowledge of the communications network topology. As such, resources are selected which are topologically closer to the endpoint thereby increasing the efficiency of the network resources on a network-wide basis.

Abstract: A conference bridge is selected for a conference call so as to reduce the overall cost of the conference call, and the conference bride selected may be changed dynamically, e.g., as parties are added or dropped from the conference call, so as to continuously maintain the low cost of the conference call. User telephones are connected via device servers, which may include a packet circuit gateway (PCG), to a packet network which provides both transport and service. Accordingly, in response to a request for a conference call, the packet network determines the parties to be on the conference call and selects a conference bridge that results in the lowest cost for the conference call, e.g., a bridge located more closely to two of the parties on the conference call. In the event the parties on the conference call change, e.g., by adding an additional party and possibly also by dropping a party already on the call, a new conference bridge is selected for the call that would keep the cost low for the call as configured with the revised parties and the information streams from all of the parties that remain on the call are directed the new conference bridge. Once the transition to the new conference bridge is completed, the old conference bridge is released for use by another conference.

Abstract: A technique is provided which advantageously facilitates the dynamic recovery from faults in one or more communication channels. In accordance with the technique, the dynamic adjustment of DSL bandwidth allocation and/or symmetry across communications channels is combined with a dynamic bonding mechanism that, in cases of single or multiple loop failures, creates the appearance of a single higher-bandwidth channel by combining and/or distributing the communications traffic across the still available physical communications channels. In this way, the channel bonding technique advantageously facilitates the dynamic recovery from faults in one or more communication channels while preserving a symmetric bandwidth channel allocation.

Abstract: A technique for dynamically adjusting the attributes of a DSL communications channel to satisfy varying bandwidth allocations and/or symmetry requirements. More particularly, the symmetry and/or bandwidth allocation across a communications channel, e.g. a local loop, is dynamically adjusted to satisfy particular communications transmission requirements. The dynamic adjustment of the symmetry and/or bandwidth allocation is made as a function of monitoring of the real-time usage pattern across the communications channel. Further, the dynamic adjustment of the symmetry and/or bandwidth allocation can also be made as a function of a request received from a particular application employing the communications channel. Advantageously, both symmetric and asymmetric DSL applications are satisfied across the same communications channel by dynamically adjusting the available bandwidth and/or symmetry of the communications channel.

Abstract: Telephone service is supplied using a distributed architecture that employs a collection of resources each of which exposes a hierarchical namespace. The architecture includes two fundamental resource types, the device server and the call coordinator, which are interconnected by a network employing a common protocol, eg., TCP/IP. The interaction between the various resources follows "client-server" principles to implement end-to-end communication. Device servers represent physical/logical telephone devices, which include a) end-point device servers and b) gateway device servers. End-point device servers 1) represent controls for communication, such as keypads, indicator lamps, and displays, and 2) perform media rendering, e.g., voice digitization, transport, and reconstruction. Gateway device servers have two "sides". One side is implemented to appear to a call coordinator as if it were a device server, and the other side has an interface adapted to interwork with a preexisting island of telephone service. In the term "device server", "server is used in the conventional manner of the "client-server" architecture, where the server serves request from the clients and does not take action unless it is in response to a client request. A call coordinator functions in the role of the "client". The device servers are unaware of communication state, which is maintained by the call coordinator and exposed as a hierarchical namespace. The call coordinator treats the processing of a call as a sequence of steps each of which can be implemented by a small piece of computer executable code called a "feature applet".

Abstract: Enhanced Internet service is provided over an ISDN line by eliminating from the D-channel any packets that will introduce unacceptable delay in packets transmitted over the B-channel. The enhancement is achieved by segregating the packets between the B-channels and the D-channel based on the stream to which the packets belong. Furthermore, instead of bonding together both B-channels and the D-channel, only the B-channels may be bonded to each other, while the D-channel is kept independent. To do so, instead of using MLPPP over the combination of both B-channels and the D-channel, as in the prior art, MLPPP is used over only both B-channels, while data that is separately directed to the D-channel employs another protocol, e.g., PPP. Advantageously, the number of protocols used to transmit the information over the D-channel may be reduced, resulting in a higher bandwidth for applications. The bandwidth of the D-channel can be dynamically throttled by an access server. Such throttling can be used to prevent the access server, or the packet switch in the central office switch that is serving the ISDN line, from being flooded. The central office switch supporting the ISDN line may be supplemented to support frame relay over the D-channel, which can provide performance improvement. The frame relay packets are automatically routed to the access server. Packets may also be limited to being sent only over the D-channel.
