摘要： A method is provided for enabling a base station to infer a compact topology graph among a set of mobile nodes in its cell, the mobile nodes having a secondary radio to enable inter-nodal communication. This methodology ensures that nodal membership information is gathered within approximately 100 ms, and additional topology information is gathered from all the mobile nodes within approximately 300 ms over Wi-Fi radios. In dense networks, this time can be reduced to within 100 ms.

摘要： Various methods and devices are provided to address the need to reduce paging latency. In one method, a wireless network determines (201) that a page for a mobile needs to be transmitted over a target broadcast area. The wireless network schedules (202) the transmission of the page in an upcoming paging timeslot based on the target broadcast area and then pages (203) the mobile in the target broadcast area before transmitting an earlier scheduled page for another mobile with a different target broadcast area.

摘要： A computer-readable medium has tangibly embodied thereon and accessible therefrom a set of instructions interpretable by at least one data processing device. The set of instructions is configured for causing the at least one data processing device to carry out operations for estimating a delay for each one of a plurality of packets of a VOIP traffic flow and for allocating a delay budget for each one of the packets dependent upon the estimated delay thereof. Such estimating is performed at a fixed location between end locations of a path over which the packets traverse and is performed using packet timestamp information acquired from the packets only at the fixed location.

摘要： An efficient protection scheme for MPLS multicast is disclosed for protection of Point-to-Multi-Point LSP connections. The efficient protection scheme for MPLS multicast includes a pair of Redundant Multicast Trees for each multicast connection which connects the source of a multicast LSP to all its destinations in such a way that in the event of a single link or node failure in the network, every destination node is still connected to the root node in at least one of the two trees. Furthermore, a method is disclosed that ensures that existing Redundant Multicast Trees can adapt to changes in the set of destination nodes and/or network topology changes without significant modifications. The efficient protection scheme for MPLS multicast is particularly useful for reducing the protection bandwidth requirements over protection methods known in the art.

摘要： A capability is provided for supporting fault-resilient multicast using multiple sources. A method for supporting fault-resilient propagation of multicast traffic using Redundant Multicast Trees (RMTs) includes identifying each potential Shared Risk Link Group (SRLG) conflict associated with a pair of RMTs providing node-disjoint paths to a plurality of destination nodes, identifying each potential SRLG conflict that is an actual SRLG conflict, and, for each actual SRLG conflict, determining a detour path for protecting the links of the actual SRLG conflict. The pair of RMTs includes a first RMT from a first multicast source node to each of the destination nodes and a second RMT from a second multicast source node to each of the destination nodes. Each potential SRLG conflict includes a plurality of links. A potential SRLG conflict is determined to be an actual SRLG conflict if first and second paths for one of the destination nodes over the respective first and second RMTs each traverse at least one link of the potential SRLG conflict.

摘要： Association control is utilized for associating wireless local area network users with at least one wireless local area network access point and thereby achieving simultaneous fairness and load balancing. In the present method, a network operation center receives user parameters from each user in the wireless network via the access points. It then sets out both to determine a set of associations between each user and one or more access points based on the user parameters using fractional load balancing and produce a second set of associations by rounding so that, in said second set, each user is associated with only one access point. The present method achieves close to optimal load balancing and max-min fairness while outperforming commonly-used heuristic approaches.
摘要翻译：关联控制用于将无线局域网用户与至少一个无线局域网接入点相关联，从而实现同时的公平性和负载平衡。在本方法中，网络操作中心经由接入点从无线网络中的每个用户接收用户参数。然后，它们基于使用分数负载平衡的用户参数来确定每个用户与一个或多个接入点之间的一组关联，并通过舍入来产生第二组关联，使得在所述第二组中，每个用户相关联只有一个接入点。本方法实现了接近最佳负载平衡和最大公平性，同时优于常用启发式方法。
