    Abstract: Efficient D2D link integration can be achieved by allowing mobile devices to independently initiate D2D/connection-proxy discovery without re-broadcasting beacons originating from the wireless access point. A mobile station wanting to establish a D2D link may broadcast a search message to neighboring mobile stations, which may return offer messages specifying a connection quality and/or parameters of the candidate indirect connection. The requesting mobile station may then select one of the responding neighboring mobile stations through which to establish the indirect connection. Responding mobile stations may delay offer message transmission by a period that is proportional to a connection quality to reduce offer message redundancy.

    Abstract: Network caching performance can be improved by allowing users to discover distributed cache locations storing content of a central content server. Specifically, retrieving the content from a distributed cache proximately located to the user, rather than from the central content server, may allow for faster content delivery, while also consuming fewer network resources. Content can be associated with distributed cache locations storing that content by cache location tables, which may be maintained at intermediate network nodes, such as border routers and other devices positioned in-between end-users and central content servers. Upon receiving a query, the intermediate network nodes may determine whether the content requested by the query is associated with a cache location in the cache location table, and if so, provide the user with a query response identifying the associated cache location.

    Abstract translation: 通过允许用户发现存储中央内容服务器内容的分布式高速缓存位置,可以提高网络缓存性能。 具体来说,从分布式高速缓存检索内容,而不是从中央内容服务器,而不是来自中央内容服务器,可以允许更快的内容传送,同时也消耗更少的网络资源。 内容可以与通过高速缓存位置表存储该内容的分布式高速缓存位置相关联,高速缓存位置表可以在诸如边界路由器和位于最终用户与中央内容服务器之间的其他设备的中间网络节点处维护。 在接收到查询之后,中间网络节点可以确定查询所请求的内容是否与高速缓存位置表中的高速缓存位置相关联,如果是,则向用户提供标识相关联的高速缓存位置的查询响应。

    Abstract: It is possible to implement traffic engineering policies in a packet switched network by dynamically configuring different transport protocols to be used over different path segments of an end-to-end path. Specifically, a controller may communicate forward information base (FIB) control signaling instructions to network nodes along an end-to-end path. The FIB signaling instructions may configure network nodes on different path segments of the end-to-end path to route a traffic flow using different path transport protocols. For example, the FIB signaling instructions may assign a link-based transport protocol to a first path segment, and a path-based or source-based transport protocol to a second path segment. Alternatively, the controller may indirectly assign transport protocols to regions/path segments by classifying regions of a packet switched network as link-preferred regions, path-preferred regions, or no-preference regions.

    Abstract translation: 通过在端到端路径的不同路径段上动态配置不同的传输协议,可以在分组交换网络中实现流量工程策略。 具体地,控制器可以沿着端到端路径向前向信息库(FIB)控制信令指令传送到网络节点。 FIB信令指令可以在端到端路径的不同路段上配置网络节点,以使用不同的路径传输协议来路由业务流。 例如,FIB信令指令可以将基于链路的传输协议分配给第一路径段,以及将路由或基于源的传输协议分配给第二路径段。 或者,控制器可以通过将分组交换网络的区域分类为链路优选区域,路径优选区域或不偏好区域来间接地将传输协议分配给区域/路径段。
