摘要： The invention provides a coordination layer of coordinating entities provided intermediate the admission control interfaces of the transport network domains, and any QoS signaller which signals QoS requests on behalf of the application layer. The coordination layer acts to distribute an admission control request across the multiple transport network domains by the use of coordination request messages containing the admission control request being forwarded through the coordination layer of coordinating entities. At each coordinating entity the admission control request is passed on to the admission control interface of the transport network which the coordinating entity serves, and an admission control response obtained. This admission control response is then combined with admission control responses from the other domains which are propagated through the coordination layer via coordination messages. The result is that the coordination layer acts to combine the various admission control responses into a combined response, which can be provided back to the QoS signaller (or other requesting entity). Thus, coordination of admission control across multiple transport network domains is achieved, without a QoS signaller having to contact each individual domain.
摘要翻译：本发明提供了在传输网域的接纳控制接口之间提供的协调实体的协调层，以及代表应用层对QoS请求进行信令的任何QoS信号器。协调层通过使用包含通过协调实体的协调层转发的准入控制请求的协调请求消息来跨越多个传输网络域来分发准入控制请求。在每个协调实体，接纳控制请求被传递到协调实体服务的传输网络的接纳控制接口，并且获得接纳控制响应。然后，该接纳控制响应与通过协调层通过协调消息传播的其他域的准入控制响应相组合。结果是，协调层用于将各种接纳控制响应组合成组合响应，其可以被提供回QoS信号器（或其他请求实体）。因此，实现跨多个传输网络域的准入控制的协调，没有QoS信号器必须联系每个单独的域。

摘要： The present invention provides a method and system wherein congestion information is taken from a lower level in the protocol stack and used for congestion marking in a higher layer. In particular, the method and system of the invention from a first aspect provide for congestion information in the lower layer to be generated downstream at a congested node, and to be fed back upstream to a source node. The source node then passes the congestion information, or information derived therefrom, up to the corresponding network element responsible for higher layer functions in the protocol stack, where higher level congestion marking can then be performed in dependence on the received lower level congestion information. Thus, congestion information from the lower layer which can typically be generated earlier before significant congestion occurs can be used in higher layer congestion control functions. Preferably the lower layer is the data link layer, and the higher layer is the network layer.

摘要： A method and system is described that adjusts the allocated capacity of a network between services, or service or traffic classes, in dependence on a congestion-influenced shadow price indication in respect of each service or class. In this respect, instead of viewing the congestion price as a cost of using already allocated unit of capacity, such a shadow price indication can be viewed as an indicator of the value obtainable from allocating an extra unit of capacity to a service or class. By so doing the shadow price indication becomes a factor to be taken into account in deciding on capacity allocation between services or classes, with a high shadow price indication for a service or class indicating that additional value would likely be obtained by allocating an additional unit of capacity to the service or class.

摘要： In embodiments of the invention when a session request is received the value assigned to that session is compared to present congestion costs in the network at the present time. If the value of the session exceeds the cost then the session is accepted; otherwise it is rejected. It is possible to show mathematically that, provided this strategy is used for all session requests, then, when demand exceeds supply for a given resource, the congestion measurement for that resource rises to become equal to its shadow price. Here, in a model of a capacity constrained network, the shadow price of a capacity constraint is the cost to other users of using one unit of capacity. Congestion measurements can therefore be used to provide a “cost” (to other users) of admitting the flow to the network, which can then be compared against the “value” (to the network operator) of admitting the flow during the admission control evaluation. Additionally, this “cost” vs. “value” comparison can be used for path selection, as well as any other resource management decision. For example, in particularly preferred embodiments a session is not only admitted based upon the cost value comparison, but is also assigned to a particular path which maximizes value minus cost.

摘要： Embodiments of the invention provide a network management sub-system which is preferably logically separate from the routing nodes (including gateway nodes) of a network. The network management sub-system receives load information relating to present packet flows on existing predetermined paths in the network, and when a request for admittance of a new packet flow is received, is able to make a decision as to whether the new flow should be both: i) admitted to the network; and ii) on to which path; in substantially the same process step. This is possible because the admission control and routing algorithms are integrated into a single process, the result of which provides both an admission control decision as well as a routing decision at the same time. By performing such an operation in a management sub-system which is separate from the routing nodes, there is no need for such functionality to be duplicated in nodes across the network, and instead the routing nodes are relieved of the burden of having to make such decision themselves. As a consequence, the network nodes can be kept simpler, and network control can be retained by the network operator in the management sub-system.

摘要翻译：在本发明的实施例中，当接收到会话请求时，将分配给该会话的值与当前网络中的当前拥塞成本进行比较。如果会话的价值超过成本，则会话被接受; 否则被拒绝。有可能在数学上显示，只要该策略用于所有会话请求，那么当需求超过给定资源的供应时，该资源的拥塞度量就会变得等于其影子价格。这里，在容量约束网络的模型中，容量约束的影子价格是其他用户使用一个容量单位的成本。因此，拥塞测量可用于向网络提供“成本”（向其他用户），该流量可以与入网控制评估期间允许流量的“价值”（对网络运营商）进行比较。此外，这种“成本”与“价值”比较可用于路径选择以及任何其他资源管理决策。例如，在特别优选的实施例中，会话不仅基于成本值比较而被允许，而且还被分配给最大化值减去成本的特定路径。
