Abstract: A communications system for executing distributed processes on garbage collecting virtual machines. More particularly, distributed applications are providing using garbage collection delivered as a function of certain timing variables such as the time until a process will require its next garbage collection cycle, process hibernation time, and the actual total garbage collection time per process. Advantageously, distributed application programs are executed on garbage collecting virtual machines without any adverse processing impact resulting from the garbage collection process.

Abstract: A media exchange monitor is disclosed that selectively (i) introduces a mixer into a two-party call when the two-party call becomes a conference call (ad-hoc conference), and (ii) removes the mixer when one or more conference call participants drop out, leaving only two participants behind. When a party to a two-party call requests to convert the call into a conference call, the packet telephony system responds to the conference call request by connecting a mixer to service the conference call between the parties. When parties drops out of a conference call, leaving only two parties behind, the mixer is removed from the conference call. In one implementation, the mixer is removed from the conference call only if the two remaining parties can exchange media directly. When the media connection among the parties must be changed to introduce or remove the mixer, the media exchange monitor achieves the desired connectivity by initially querying the parties for their capabilities. Thereafter, the media exchange monitor instructs the parties to establish a direct connection for a two-party call or to connect to the mixer for a conference call. The media exchange monitor processes the results of the capability query to select a compatible compression algorithm.

Abstract: In a teleconference, audio communications between attendees which may be located at different locations are processed by a mixer. Audio signals, representative of sound effects including utterances by the attendees, are transmitted to the mixer respectively. The mixer derives samples from the respective received signals. During each sample interval, the mixer selects the sample having the highest energy to become a mixed sample output for each user, except the user contributing the highest energy sample. For such a user, the mixer selects the sample having the next highest energy to become the mixed sample output. The mixed sample outputs are transmitted back to the users respectively, thereby realizing the audio communications in the teleconference.

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 translation: 使用分布式架构提供电话服务，分布式架构采用每个资源集合来暴露分层命名空间。 该架构包括两个基本资源类型，即设备服务器和呼叫协调器，它们由采用通用协议（例如TCP / IP）的网络互连。 各种资源之间的交互遵循实现端到端通信的“客户端 - 服务器”原则。 设备服务器代表物理/逻辑电话设备​​，其中包括a）端点设备服务器和b）网关设备服务器。 端点设备服务器1）表示诸如键盘，指示灯和显示器的通信控制，以及2）执行媒体呈现，例如语音数字化，传输和重建。 网关设备服务器有两个“边”。 一方面被实现为呼叫协调器看起来像是设备服务器，而另一端具有适于与预先存在的电话服务电话互通的接口。 在“设备服务器”一词中，“服务器以”客户机 - 服务器“架构的常规方式使用，其中服务器提供来自客户端的请求，除非是响应于客户端请求，否则不采取行动 协调器在“客户端”的角色中起作用，设备服务器不知道通信状态，由通话协调器维护并作为分层命名空间公开，呼叫协调器将呼叫的处理视为每个步骤的一系列步骤 这可以通过称为“特征小程序”的小型计算机可执行代码来实现
