摘要： In order to achieve optimized delivery of multicast traffic between L2 OTV sites across an L3 multicast service provider core infrastructure, embodiments of the present disclosure describe building different provider multicast data trees rooted at a source site for individual per-vlan (*,G)/(S,G) streams. Building such provider trees may require individual sites to discover multicast sources local to their network and subsequently announce to all receiver sites the multicast data trees (DS, DG) to be used to deliver such multicast traffic. The present disclosure describes the coordination between OTV edge devices for the (S,G) to (DS, DG) mapping originated by the source OTV edge device where the multicast traffic is originated.

摘要： The invention provides a method and system for providing unique ATM End System Addresses, in which each new device is assigned a unique address in an ATM network while allowing all new devices performing the PNNI protocol in a selected set (such as all those from a single manufacturer) to be assigned by default to the same peer group. In the invention, a first portion of the ATM address (from which the default peer group ID is determined) is by default configured to equal a selected value unique to the manufacturer (or another selected class of devices), which assures that all devices from the same manufacturer (or in that selected class) are by default configured in the same peer group for PNNI protocol purposes, while a second portion of the ATM address (comprising a switch number ID) and a third portion of the ATM address (comprising a device number ID) are by default both configured to equal a unique value for the device (such as a MAC address), which assures that each device is configured with a unique ATM address. The third portion of the ATM address may alternatively be determined using a different method, so long as selection of the third portion causes each device to be assigned a unique ATM address by default.
摘要翻译：本发明提供了一种用于提供唯一的ATM终端系统地址的方法和系统，其中每个新设备在ATM网络中被分配唯一的地址，同时允许在所选择的集合中执行PNNI协议的所有新设备（诸如来自单个制造商）默认分配给同一个对等组。在本发明中，ATM地址的第一部分（从中确定默认对等组ID）被配置为等于制造商（或另一选定类别的设备）唯一的选定值，这确保所有设备从默认情况下，相同的制造商（或所选类别）在同一对等组中为PNNI协议目的配置，而ATM地址的第二部分（包括交换机号码ID）和ATM地址的第三部分（包括默认情况下，设备号码ID都被配置为等于设备的唯一值（例如MAC地址），这确保每个设备配置有唯一的ATM地址。可替代地，可以使用不同的方法来确定ATM地址的第三部分，只要选择第三部分使每个设备默认地被分配唯一的ATM地址即可。

摘要： The invention provides a method and system for selecting one particular interface between a pair of adjacent nodes in an ATM network for assignment to a call in that network. The cell rate available on each possible interface is examined and compared with the cell rate expected for the call, and one of the interfaces is selected and assigned responsive to those cell rates. (1) The interface can be chosen which preserves the maximum remaining cell rate for future calls. (2) The interface with the highest-speed available link can be chosen, so long as cell rate capacity is available on that interface for the call.

摘要： The invention provides a method and system for selecting routes in a switching network with resource reservation, such as an ATM network. A set of routes are periodically precomputed, so that routes are known between any sending node and any receiving node, subject to resource reservation requirements. Each incoming call has its resource requirements, such as call size, compared with a selected threshold, and if the requirements exceed the threshold, a route is dynamically recomputed for the call. Other aspects of routing may be responsive to the calls' resource requirements. For example, a ratio of required resources with quality-of-service restrictions to required resources without such restrictions may be used to determine whether to reject the call, responsive to the call's resource requirements. The call size may be compared against another selected threshold, and the decision to determine whether to use that ratio to reject the call may be made responsive to comparisons against one or both thresholds.
摘要翻译：本发明提供了一种用于在诸如ATM网络的资源预留的交换网络中选择路由的方法和系统。周期性地预先计算一组路由，使得在任何发送节点和任何接收节点之间已知路由，但需要资源预留的要求。每个来电具有与所选阈值相比的资源需求，例如呼叫大小，并且如果需求超过阈值，则为呼叫动态地重新计算路由。路由的其他方面可以响应于呼叫的资源需求。例如，可以使用所需资源与服务质量限制与所需资源的比例，而不存在这种限制，以响应于呼叫的资源需求来确定是否拒绝呼叫。可以将呼叫大小与另一所选择的阈值进行比较，并且可以响应于对一个或两个阈值的比较来确定是否使用该比率拒绝该呼叫的决定。
