Abstract: An edge router receives datagrams to be forwarded an SVC. If the SVC is not already set up, the edge router buffers the datagrams until the SVC set up is complete. The buffered datagrams are forwarded once the SVC set up is complete. According to another aspect of the present invention, different buffering requirements are supported for different user applications. A policy table may be configured by a service provider specifying the requirements associated with potentially each flow (e.g., combination of source/destination IP addresses, source/destination port number), and the datagram on each flow may be buffered accordingly.

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: Data related to multiple point-to-point sessions is transmitted on a single virtual circuit of a ATM based network. In an embodiment implemented in accordance with ATM Adaptation Layer 2 (AAL2), the data related to each session is transported on a channel of the AAL2 virtual circuit. As the intermediate devices in the virtual circuit path merely need to maintain tables for one virtual circuit, the overhead on the devices may be minimized. By assigning data of a session to a channel provided by an adaptation layer, addition fields or higher level protocols may not be needed to transport the data related to the sessions.

Abstract translation: 与多个点到点会话相关的数据在基于ATM的网络的单个虚拟电路上传输。 在根据ATM适配层2（AAL2）实现的实施例中，与每个会话相关的数据在AAL2虚拟电路的信道上传输。 由于虚拟电路中的中间设备只需要维护一个虚拟电路的表，所以可以将设备上的开销降至最低。 通过将会话的数据分配给由适配层提供的信道，可能不需要添加字段或更高级协议来传送与会话相关的数据。

Abstract: A link device facilitating communication between a wireless communication terminal and a resource-constrained device. According to an aspect, the link device receives messages from the wireless communication terminal on a wireless path according to a first protocol, converts the messages into a second protocol, and forwards the converted messages in the second protocols to the resource-constrained device on a wired path connecting the link device to the resource-constrained device. In an embodiment, the first protocol corresponds to HTTP protocol and the second protocol corresponds to a simpler protocol which requires relatively lesser processing and memory resources.

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。
