    Abstract: Methods and systems are disclosed for enabling centralized path definition and policy with distributed path setup, and centralized path setup control with distributed path utilization constraints. In one example, a path computation client (PCC) requests, utilizing opaque PCE profile identifiers, a path computation from a path computation element (PCE). The PCE profile identifier corresponds to path computation constraints, stored local to PCE, and are unknown to the PCC. Advantageously, the PCE profile identifiers allow the PCC to initiate path computation requests based on information local the PCC while leveraging centralized path computation by the PCE. In another example, a PCE requests, utilizing opaque PCC profile identifiers, that a PCC initiate a path. The PCC profile identifier corresponds to path usage parameter constraints, stored local to PCC, and are unknown to the PCE. Advantageously, the PCC identifiers allow the PCE to marshal path initiation while leveraging distributed resources to enforce compliance with usage parameters.

    Abstract translation: 公开了用于实现具有分布式路径建立的集中路径定义和策略以及具有分布式路径利用约束的集中路径设置控制的方法和系统。 在一个示例中,路径计算客户端(PCC)使用不透明PCE简档标识符从路径计算元件(PCE)请求路径计算。 PCE配置文件标识符对应于PCE本地存储的路径计算约束,并且对于PCC是未知的。 有利地,PCE简档标识符允许PCC基于PCC本地的信息来发起路径计算请求,同时利用PCE的集中路径计算。 在另一示例中,PCE使用不透明的PCC简档标识符来请求PCC发起路径。 PCC配置文件标识符对应于PCC本地存储的路径使用参数约束,并且对于PCE是未知的。 有利地,PCC标识符允许PCE调度路径启动,同时利用分布式资源来强制遵守使用参数。
