摘要： A network may include a plurality of nodes forming a first layer and a sub-set of the plurality of nodes forming a second layer. The first layer may follow a first routing objective in routing traffic, and the second layer may develop constraints based on the first routing objective and follow a second routing objective within the developed constraints in routing traffic. In another network, the second layer may follow a second routing objective in routing traffic, and the first layer may develop constraints based on the second routing objective and follow a first routing objective within the developed constraints in routing traffic.

摘要： A method and apparatus for performing template-based prefix caching advantageously identifies common prefixes (i.e., initial video segments) in video titles, stores common prefixes only once in a prefix cache, and uses these common prefixes when serving requests for video content. This advantageously enables a prefix cache to scale to a large number of video titles, since the cache stores each common prefix only once. A new video title that uses an already existing prefix may be advantageously added without requiring additional storage in the prefix cache. Template-based prefix caching also advantageously reduces the bandwidth required to distribute prefixes when new titles are ingested into the system—if the required template is already available in the prefix cache, prefix-caching is enabled instantly for this title and no additional bandwidth is required to distribute the prefix.
摘要翻译：用于执行基于模板的前缀缓存的方法和装置有利地识别视频标题中的公共前缀（即，初始视频片段），在前缀高速缓存中仅存储一次公共前缀，并且在为视频内容提供请求时使用这些公共前缀。这有利地使得前缀高速缓存能够扩展到大量视频标题，因为高速缓存仅存储每个公共前缀一次。可以有利地添加使用已经存在的前缀的新的视频标题，而不需要前缀高速缓存中的附加存储。基于模板的前缀缓存还有利地减少了当新标题被摄入系统时分配前缀所需的带宽 - 如果所需的模板在前缀高速缓存中已经可用，则为该标题立即启用前缀缓存，并且不需要额外的带宽分发前缀。

摘要： The invention is directed to energy-efficient network processing of delay tolerant data packet traffic. Embodiments of the invention determine if an aggregate of time critical traffic flow rates and minimum rates for meeting QoS requirements of delay tolerant traffic flows exceeds a combined optimal rate of packet processing engines of a network processor. In the affirmative case, embodiments set the processing rate of individual packet processing engines to a minimum rate, such that the cumulative rate of the packet processing engines meets the aggregate rate, and schedule the delay tolerant flows to meet their respective minimum rates. Advantageously, by throttling the processing rate of only delay tolerant traffic, energy consumption of network processors can be reduced while at the same time QoS requirements of the delay tolerant traffic and time critical traffic can be met.

摘要： A peer-to-peer accelerator system is disclosed for reducing reverse link bandwidth bottlenecking of peer-to-peer content transfers. The peer-to-peer accelerator system contains a peer-to-peer proxy which resides in the core of the network. When a peer-to-peer bootstrap message from an asymmetrically connected client occurs, the proxy intercepts the message and instantiates an agent which will perform file transfers on the asymmetrically connected client's behalf thereby eliminating the need for the client to effect file content transfers over the reverse link. The peer-to-peer accelerator system is particularly useful for overcoming the bottlenecking and reverse link contention problems of peer-to-peer file transfer systems known in the art.
