Abstract: The bandwidth of a virtual circuit is changed when the aggregate bandwidth available on path(s) to an adjacent ATM device (through which the VC is provided) changes. The change of bandwidth may be implemented by changing the QoS parameters associated with the virtual circuits. Thus, for example, when one of the paths becomes non-operational, the bandwidth of a virtual circuit may be reduced in a fair manner.

Abstract translation: 当路径上可用的相邻ATM设备（通过VC提供）的总带宽发生变化时，虚拟电路的带宽会发生变化。 可以通过改变与虚拟电路相关联的QoS参数来实现带宽的改变。 因此，例如，当其中一个路径变得不可操作时，可以以公平的方式减少虚拟电路的带宽。

Abstract: To send a connection control message associated with a first set of attributes, only a difference of the first set of attributes from a second set of attributes associated with an already active virtual circuit (to a common destination) may be sent (contained in the connection control message). The devices receiving the message may create the necessary configuration for the new virtual circuit by modifying a copy of the configuration of the active virtual circuit. Processing requirements may be minimized as the devices may not need to parse and decode long list of information element. The feature may be particularly important in setting up a virtual circuit for voice calls, as a long list of attributes may be associated with each virtual circuit, but the difference of attributes being only minimal.

Abstract: An end system (“first end system”) concluding that a bi-directional virtual circuit is operational if the other end system (at the other end of the virtual circuit) has determined that the virtual circuit is operable based on the loopback cells. In other words, the first end system may not send loopback cells, and instead rely on the determination of the other end system. As a result, the total number of loopback cells may be reduced on a network backbone.

Abstract: Setting up a group of virtual circuits using a single set up message request. In an embodiment, fewer than all of the virtual circuits in the group are immediately provisioned, and the remaining virtual circuits are placed in an inactive status by appropriate configuration of all the devices in the path of the group of virtual circuits. Each of the inactive virtual circuits can be activated (complete provisioning) as and when required. The bandwidth overhead on the networks is reduced as fewer signaling messages would be used in provisioning several virtual circuits. The parsing overhead is reduced on the devices processing the signaling messages as a result.

Abstract translation: 使用单个设置消息请求设置一组虚拟电路。 在一个实施例中，组中的所有虚拟电路中的少于所有虚拟电路都被提供，并且通过对虚拟电路组的路径中的所有设备的适当配置将剩余的虚拟电路置于非活动状态。 每个非活动虚拟电路可以在需要时激活（完全配置）。 网络上的带宽开销减少，因为在配置多个虚拟电路时将使用更少的信令消息。 结果，在处理信令消息的设备上减少了解析开销。

Abstract: Moving a virtual circuit from one port interface to another when multiple port interfaces are present between two network devices. Such a move may be performed, for example, when a port interface fails or when needed to balance the load (e.g., aggregate amount of bandwidth of all virtual circuits presently assigned to a port interface) across multiple port interfaces. As a result, the port interfaces may be used efficiently.

Abstract translation: 在两个网络设备之间存在多个端口接口时，将虚拟电路从一个端口接口移动到另一个端口。 这样的移动可以例如当端口接口故障或需要平衡负载时（例如，当前分配给端口接口的所有虚拟电路的总带宽量）跨多个端口接口来执行。 结果，可以有效地使用端口接口。

Abstract: A switch may be configured to support a point-to-multi-point PVC which can be used to support a point to multi-point application. The signaling overhead is reduced due to the use of PVC, and the available bandwidth is used efficiently due to the use of the point-to-multi-point connection. Another aspect of the present invention minimizes the resources required while providing such point-to-multi-point virtual connections. A switch may minimize allocation of resources to branches that are not active. For example, a switch may determine that a branch is inactive based on the absence of reception of OAM cells in a specified duration and delete the forwarding information for the inactive branch. The switch may thus scale to support many point-to-multi-point virtual circuits having many branches.

Abstract translation: 交换机可以被配置为支持可以用于支持点到多点应用的点对多点PVC。 由于使用PVC，信令开销降低，并且由于使用点到多点连接，可用带宽被有效地使用。 本发明的另一方面使提供这种点对多点虚拟连接所需的资源最小化。 交换机可以将资源的分配最小化到不活跃的分支。 例如，交换机可以基于在指定持续时间内不存在OAM小区的接收来确定分支是不活动的，并且删除非活动分支的转发信息。 因此，交换机可以缩放以支持具有许多分支的许多点到多点虚拟电路。

Abstract: The present disclosure relates to light redirecting elements in solar energy absorption systems and envisages a light redirecting prism, a redirecting prismatic wall and a solar panel incorporating the same. The light redirecting prism has three elongate surfaces. The incident surface receives incident parallel rays of light. The redirecting surface performs total internal reflection of the light travelling from the incident surface through a predetermined range of angles and thus redirect the light. The transmitting surface transmits the redirected light at a predetermined angle out of the prism and directs the light towards a solar energy absorbing device. Further, a redirecting prismatic wall can be constructed to comprise redirecting prisms. The light redirecting prism or redirecting prismatic wall can be used in solar panels for enhancing quantum of light incident on the PV cell of the panel.

Abstract translation: 如果另一端系统（在虚拟电路的另一端）已经基于环回单元确定虚拟电路可操作，则终端系统（“第一端系统”）得出结论，双向虚拟电路是可操作的。 换句话说，第一端系统可能不发送环回小区，而是依赖于另一端系统的确定。 结果，可以在网络骨干网上减少环回单元的总数。
