Patent number: 10164886Abstract: A flow based routing method and apparatus selects a path from a plurality of different paths for assignment to a flow. The path is selected based on traffic performance measurements which identify relative congestion and performance of the different paths, so that traffic flows can be diverted away from network congestion points, thereby allowing network resources to be load balanced at a flow granularity. The present invention may be configured on physical or virtual links on an NE to enhance the forwarding of packets using the primary link and one or more alternate links to any given destination.Type: GrantFiled: February 10, 2017Date of Patent: December 25, 2018Assignee: Avaya Inc.Inventors: Jozef Babiarz, Bakul Khanna

Patent number: 9197528Abstract: Wireless networks and devices are ubiquitous today. For service providers to offer customers QoS and Service Level Agreements (SLAs) means in part providing resilient connectivity of wireless devices with good signal strength, good Signal to Noise and Interference Ratio (SNIR), and adequate useable bandwidth. Doing so requires that devices transmitting and receiving packets use over-the-air bandwidth efficiently and manage over-the-air congestion. According to embodiments of the invention QoS measurements and controls are incorporated only in the network (i.e. APs or controllers) and therefore QoS and SLAs can be achieved with all deployed client stations versus standards based approaches that require additional capabilities in network nodes, client stations and in most cases modifications to the applications.Type: GrantFiled: March 2, 2011Date of Patent: November 24, 2015Assignee: 3Inova Networks Inc.Inventors: Jozef Babiarz, Marvin Krym

Patent number: 9172648Abstract: A flow admission control module for IP traffic types monitors network topology and usage. A new flow is not admitted if it is determined that the flow would push the utilization of available bandwidth reserved for the traffic type on a link in the associated path beyond a predetermined threshold. The admission control module may, as a result of dynamic changes to network topology capacity, re-compute the link utilization for effected active flows The admission control module may also account for protection regimes in flow admission calculations.Type: GrantFiled: December 8, 2014Date of Patent: October 27, 2015Assignee: RPX Clearinghouse, LLCInventors: Allan Sand, Jozef Babiarz, Dany Sylvain

Patent number: 9106552Abstract: A technique for end-to-end admission control of real-time packet flows is disclosed. In one embodiment, the technique may be realized as a method for end-to-end admission control of real-time packet flows in a network having a plurality of network elements. The method may include transmitting at least one probe packet from a first network element to a second network element via a network path, determining, at at least one intermediate network element on the network path, at least one flow rate associated with a plurality of packets, marking at least one predetermined bit in the at least one probe packet if the at least one flow rate is greater than a predetermined rate, and controlling an admission of additional packets into the network based at least in part on the marking of the at least one predetermined bit in the at least one probe packet.Type: GrantFiled: July 18, 2014Date of Patent: August 11, 2015Assignee: RPX Clearinghouse LLCInventors: Jozef Babiarz, Kwok Ho Chan

Patent number: 8391224Abstract: A wireless communication system is able to balance load in a wireless network based on radio frequency (RF) utilization, signal strength, quality of signal (QoS), and other measures. The load may be dynamically moved to other wireless access points within the wireless network based on the amount of load on one or more of the access points and on the measures. As such, at different load conditions, the system can change the methods of how to determine which access point should handle a communication session. Further, the system provides methods for proactively adjusting the load in the wireless network before any one access point reaches its capacity.Type: GrantFiled: March 2, 2010Date of Patent: March 5, 2013Assignee: Avaya Inc.Inventors: Marvin Krym, Jozef Babiarz, Lambertus Verberk, Kenan Xu, Ping Wu

Patent number: 8385197Abstract: A communication system is provided that can control which communication sessions with mobile devices are admitted to a wireless access point. The admission decisions are based on actual measurements of radio frequency (RF) utilization. The RF utilization is determined on a per access class basis. Access classes may be defined by protocol but are, generally, voice, video and data. Thus, the system provides the ability to determine admissions that allows for the incorporation of factors including collisions, the distance from the access point to which a mobile device is communicating, and other factors.Type: GrantFiled: March 2, 2010Date of Patent: February 26, 2013Assignee: Avaya Inc.Inventors: Marvin Krym, Jozef Babiarz, Lambertus Verberk, Xiao-Gao Liu, Tarak Shingne
