Abstract: A system can monitor the server for indications of an attack and adjusts server settings accordingly. In response, the system can increase server tolerance in a systematic way to deal with DDoS by adjusting server settings appropriately. Conversely, when the server is not under attack, the settings can be adjusted to those for standard operations (e.g., adjusted downward), as they are more optimal for normal, non-attack operations.

Abstract: Implementations of the present disclosure involve an apparatus and/or method for a network topology discovery engine that detects one or more network elements and/or one or more connections between a plurality of network elements. The network topology discovery engine transmits a request for operational and connection information from at least one network element. In response, network topology information is received by the network topology discovery engine by one or more elements of the network that provide information on the topology and operational state of the telecommunications network. The received information may then be stored in a network topology database. This network topology database may be utilized by the network or a related component for information or maintenance of the telecommunications network, such as an obsolescence tracker to detect one or more network elements that could be replaced or upgraded.

Abstract: In an embodiment, a method configures a network to route data on a first network service that connects a user's network with a service provider network. In the method, an instruction to route data from the network addressed to a hostname on the first network service is received, According to the hostname, a first IP address that addresses a server identified by the hostname is determined. A second IP address is also determined as the second IP address of the specific network service. Finally, a message is sent to the user's network that specifically instructs the user's network to route data addressed to the first IP address to the second IP address. The message causes configuration of a router on the user's network to route data on the first network service. System and computer program product embodiments are also disclosed.

Abstract: Aspects of the present disclosure involve systems, methods, computer program products, and the like, for managing the distribution of content and/or communications from a computer network to an end user of the network. In general, the system receives a request for content from the network from a user of the network and determines a server or content providing component within the network to provide the content to the user. In addition, the network may reduce the number of components and distance requests for the content are transmitted through the associated networks. In one embodiment, the network may provide altered destination paths to one or more access networks through which the end user accesses the network. The altered destination paths may be used by the end user's service provider or local network to select an access network for accessing the computer network to minimize the impact on the computer network for providing the content to the end user.

Abstract: A differentiated routing system is provided for routing a communication service according to an access point of a subscriber terminal to a first network domain. The system includes a computing system executing a core routing engine (CRE) that receives a request for a communication service from the subscriber terminal. When the communication service is to be routed to a second network domain, the CRE identifies an access point at which the subscriber terminal accesses the first network domain, includes a tag in the request according to the identified access point. The tag includes information to be used by the second network domain for routing the communication service. The CRE then transmits the request to the second network domain.

Abstract: Embodiments generally disclosed herein include methods and systems for calculating incremental network costs between logical city pairs in a network (each city pair being in communication across the network via one or more physical links). For example, the method includes a cost analyzer that, for each physical link in the network, determines a steady state capacity allocation associated with each city pair in the network and, in the same vein, determines a restoration capacity allocation associated with each city pair in the network. The cost analyzer is capable of calculating an incremental cost per unit of traffic for a given city pair based on: i) the steady state capacity allocation and a restoration capacity allocation associated with a given city pair, as compared to, ii) the aggregate steady state capacity allocations and restoration capacity allocations associated with each city pair in the network.

Abstract: In a content delivery network (CDN a method includes: receiving a request for a CDN service of a particular type, wherein a CDN service of said particular type defines a fixed number of configurable layers of request processing, sequentially from a first layer to a last layer; and processing said request, starting at said first layer, said processing being based on a modifiable runtime environment, said processing continuing conditionally through each of said layers in turn until either said request is terminated by one of said layers or said last layer processes said request. A layer may cause some of the processing of a request to be handled by another service. The CDN service may be selected from: delivery services, collector services, reducer services, rendezvous services, configuration services, and control services.
