Patent number: 10616900Abstract: Channel assignment for wireless access networks is directed toward improved overall communication capability of the networks. A network is formed of wireless access points (APs) coupled via wired (and/or wireless) links and enabled to communicate with clients via radio channels of each of the APs. Local information is collected at each of the APs and processed to determine channel assignments according to a Neighbor Impact Metric (NIM) that accounts for one-hop and two-hop neighbors as well as neighbors not part of the network. Optionally, the NIM accounts for traffic load on the APs. The channel assignments are determined either on a centralized resource (such as a server or one of the APs) or via a distributed scheme across the APs. The local information includes how busy a channel is and local operating conditions such as error rate and interference levels.Type: GrantFiled: June 8, 2018Date of Patent: April 7, 2020Assignee: Firetide, Inc.Inventors: Jorjeta Jetcheva, Ravi Prakash, Vinay Gupta, Sachin Kanodia, Mohan Natarajan

Patent number: 10581667Abstract: A method and a network node for localizing a fault causing performance degradation of a service. The network node calculates a first, a second and a third set of correlation values for a first time interval. Similarly, the network node calculates a fourth, fifth and sixth correlation value for a second time interval in which the fault has been detected. The sets of correlation values are taken between resource metrics, virtual execution environments, types of said each resource metric and/or servers. When at least one of the absolute values is above the threshold value, the network node adds each resource metric to a list of resource metrics, wherein the list indicates resource metric from which the fault potentially originates. Next, the network node sends the list to an entity configured to manage resources available to the set of servers, thereby enabling the entity to mitigate Service Level Agreement violation.Type: GrantFiled: September 3, 2015Date of Patent: March 3, 2020Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Jawwad Ahmed, Yue Lu
