Information regarding traffic characteristics of each service level aggregate flow and performance of the set of network resources are obtained. Based on this information, the mapping of the set of service level aggregate flows to the set of network resources is updated to achieve a more efficient utilization of the set of network resources, while fulfilling the set of service requirements.

Abstract: A method and computing device for assessing the integrity of receivers in a Cable Modem Termination System (CMTS) to improve load balancing. The method configures a load balancing manager to move registered modems between the receivers, where each receiver is tuned to a frequency. The method obtains a signal quality measurement for each receiver, and, for each receiver, evaluates the signal quality measurement, and identifies the receiver as an impaired receiver when the frequency to which the receiver is tuned is identified by the evaluating as an impaired frequency. The method attempts to repair each impaired receiver, and notifies the load balancing manager to not allow moving the registered modems to each impaired receiver that is not repairable, and to allow moving the registered modems to each receiver that transitions from impaired to unimpaired.

Upon receipt of the matching rule, the NIC may update the rules stored in its virtual switch and may process the packet in accordance with the matching rule.

Abstract: Systems, methods, and computer storage media for measuring traffic utilization are provided. The method includes timing predetermined time intervals that are relatively small to provide for real-time monitoring of a system. A count of the bytes received is identified in order to monitor a number of bytes received within the predetermined time interval. When the number of bytes received exceeds a predetermined threshold, a larger time interval is captured such that the system can identify how many times the number of bytes received exceeded the predetermined threshold within the larger time interval. When the number of bytes received exceeds the predetermined threshold a number of times greater than a violation threshold, an alarm is generated. This allows a system to monitor high frequency violations. Also, the counts for each time interval are continuously zeroed out after the time interval expires, thus, eliminating a need for calculations.

Abstract: Provided is a method of preventing a Transmission Control Protocol (TCP)-based Denial of Service (DoS) attack on a mobile device. The method efficiently prevents a DoS attack on a mobile device, which wirelessly and constantly transmits TCP packets to the mobile device using a TCP protocol and thereby exhausts resources of a wireless network and also battery power of the mobile device depending on a battery. An attack conventionally made in a wired network by abusing TCP-based three-way handshaking is more severe in the wireless network of mobile devices. To prevent such an attack on a mobile device, the method capable of checking three-way handshaking and each transition operation makes the mobile device check whether or not a received TCP packet is valid. Therefore, it is possible to efficiently prevent a DoS attack from exhausting wireless resources and battery power of the mobile device.
