摘要： A method and apparatus for performing traffic engineering, e.g., allocating bandwidth, on a wireless access network are disclosed. For example, the method determines a number of subscriber stations (SSs) that a Base Station (BS) is capable of supporting in accordance with at least one performance objective for voice traffic, wherein the at least one performance objective for voice traffic comprises a type of codec. The method then allocates bandwidth by the base station in accordance with the number of subscriber stations that the base station is capable of supporting.

摘要： A system for detecting a remotely controlled e-mail spam host. The system includes an E-mail spammer detection unit and a host traffic profiling unit. The E-mail spammer detection unit identifies E-mail Spammers based on SMTP traffic characteristics. The host profiling unit extracts traffic components from the plurality of Internet traffic associated with an E-mail Spammer; interprets the extracted traffic components and determines whether the E-mail Spammer is a compromised host. The system may also include a botnet controller detection unit that analyzes traffic associated with compromised E-mail Spammers and identifies the botnet Controller remotely controlling the compromised E-mail Spammer.

摘要： A method controls the routing of service requests to a plurality of servers using a first routing distribution algorithm. The method includes waiting a first period of time for a designated server to respond to a service request, transmitting the service request to the designated server a second time, and waiting a second period to time for the designated server to respond to the service request assigned to the designated server, the second period of time being longer than the first period of time. The method also includes determining that the designated server has failed, rerouting the service request to a different server, and routing the service requests to the plurality of servers using a second routing distribution algorithm.

摘要： Methods for providing alerts in a network are disclosed. Some methods include collecting network traffic data corresponding to multiple subsets of network addresses during a predefined time interval. A suspect subset of the subsets of network addresses that corresponds to anomalous network activity may be identified based on the network traffic data and using at least one of multiple anomaly detection metrics. A source network address within the suspect subset of network addresses that corresponds to the anomalous network activity is identified. An alert corresponding to the source network address may be generated.

摘要： A method and system for determining whether an IP address is part of a bot-network are provided. The IP-address-aggregate associated with the IP address of an e-mail sender is determined. The IP-address-aggregate is associated with an IP-address-aggregate-category based on the current SMTP traffic characteristics of the IP-address-aggregate and the known SMTP traffic characteristics of an IP-address-aggregate-category. A bot-likelihood score of the IP-address-aggregate-category is then associated with IP-address-aggregate. IP-address-aggregate-categories can be established based on historical SMTP traffic characteristics of the IP-address-aggregates. The IP-address-aggregates are grouped based on SMTP characteristics, and the IP-address-aggregate-categories are defined based on a selection of IP-address-aggregates with similar SMTP traffic characteristics that are diagnostic of spam bots vs. non-botnet-controllers spammers. Bot likelihood scores are determined for the resulting IP-address-aggregate-categories based on historically known bot IP addresses.
