摘要： An SVC is established via an ATM switch port, which includes multiple virtual paths (VPs), by associating multiple virtual user-to-network interfaces (UNIs) to each of the VPs. Each of the VPs includes multiple virtual circuit (VC) ranges, each of which corresponds to a different virtual UNI. Each VC range includes at least one VC for control and at least one VC for data transfer. Associating the virtual UNIs to each of the VPs includes mapping each virtual UNI to a corresponding VC range within a VP based on a virtual path index (VPI)/virtual channel index (VCI) of the virtual UNI initially received by the ATM switch port.
摘要翻译：通过将多个虚拟用户到网络接口（UNI）与每个VP相关联，通过ATM交换机端口建立SVC，其包括多个虚拟路径（VP）。每个VP包括多个虚拟电路（VC）范围，每个虚拟电路范围对应于不同的虚拟UNI。每个VC范围包括用于控制的至少一个VC和用于数据传输的至少一个VC。将虚拟UNI与每个VP相关联包括基于最初由ATM交换机端口接收的虚拟UNI的虚拟路径索引（VPI）/虚拟信道索引（VCI）将每个虚拟UNI映射到VP内的相应VC范围。

摘要： An SVC is established between a client and a host by dynamically configuring a host CPE device using a custom module designed for the host CPE device. The configured host CPE device enables communication between the client and the host via the SVC connection.
摘要翻译：通过使用为主机CPE设备设计的自定义模块动态配置主机CPE设备，在客户端和主机之间建立SVC。配置的主机CPE设备通过SVC连接启用客户端和主机之间的通信。

摘要： A subscriber dynamically establishes a peer-to-peer session from a source subscriber to a destination subscriber across a switched virtual circuit (SVC). A signaling (control) connection is established from the source subscriber to a server, and a connection request is sent via the signaling (control) connection to the server requesting establishment of the SVC to the destination subscriber. In response, a database is queried for information about a source switch associated with the source subscriber and a destination switch associated with the destination subscriber. Subsequently, the connection request is forwarded to a proxy signaling agent, and the proxy signaling agent signals the source switch and the destination switch to dynamically establish the SVC connection from the source switch to the destination switch. This abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.
摘要翻译：用户通过交换虚拟电路（SVC）动态地建立从源用户到目的用户的对等会话。从源用户到服务器建立信令（控制）连接，并且通过信令（控制）连接将请求建立到服务器的请求建立到目的用户的服务器发送到服务器。作为响应，查询数据库以获得关于与源订户相关联的源交换机和与目的地订户相关联的目的地交换机的信息。随后，将连接请求转发给代理信令代理，代理信令代理信令源交换机和目的交换机动态建立从源交换机到目的交换机的SVC连接。该摘要既不旨在限定本说明书中公开的发明，也不旨在以任何方式限制本发明的范围。
