Abstract: A node in a content delivery network (CDN) receives a request for content and determines information about the request. When sufficient information about the content is determined, the request is assigned to an appropriate CD service to process the request; and when insufficient information about the content is determined, the request is assigned to a generic CD service to process the request. The generic CD service processes the request; and provides updated information about the content to be used for processing future requests. An appropriate CD service processing a request may also provide updated information about the content to be used for processing future requests.

Abstract: Methods and systems are disclosed for providing third party connectivity to installed software at a customer site through a broker infrastructure. A uniform facility for powerful and secure third party access to customer software installations is provided. Multiple TCP-based session types including source code debug and database sessions are supported. A target backend and session type are selected by an authorized agent logged into the broker infrastructure. A communication session is established between environments of the agent's frontend tool and the backend. The agent can perform maintenance or troubleshooting on the backend using the full capabilities of the frontend tool. Data exchange between frontend and backend utilizes TCP connections within the communication session, and is mediated by a connectivity framework within the broker infrastructure. Customer control over access to target backends is supported.

Abstract: A method for managing traffic associated with a client domain, implemented in a server. The method includes: detecting a communication problem between the server and at least one first client node of the client domain, called failed node, identifying at least one second client node belonging to the client domain, verifying if a session between the server and the at least one second client node is active, and if no session is active: triggering a mitigation procedure on at least one IP resource associated with the client domain if at least one session is active: the use of the second client node associated with the at least one active session, called active node, to initiate an action managing the traffic associated with the client domain.

Abstract: A method for monitoring message packets that are exchanged between at least two control units. The message packets are concatenated in a data stream and each have an identifier, a payload, and a length specification of the payload described by a data item of predefined word size. The at least two control units are connected by a distributor. The distributor is connected by a first distributor port to a first of the at least two control units, is connected by a second distributor port to a second of the at least two control units, and is connected by a third distributor port to a computer system. The data stream flows through the first and distributor port for communication between the first node and the second node. The computer system has a memory, and information on the respective identifiers of the message packets is stored in the memory.

Abstract: Systems and methods are described for communications between computing devices via a stateless high-volume network address translation (“NAT”) service. The stateless high-volume NAT service manages high volumes of connections between networks by encoding at least part of the information needed to manage a connection in an encoded IPv6 address, which is then used by a NAT device or application as its sending address when relaying data from a source to a destination. The encoded IPv6 address may contain information such as the IPv4 address of the source, the IPv4 address of the destination, the protocol used to communicate, the source and destination ports, and the like. When the destination sends a response to the encoded IPv6 address, the NAT device decodes the IPv6 address to obtain the encoded information, and then uses that information to deliver the response to the source.

Abstract: According to one embodiment, a signal processing apparatus includes processing circuitry. The processing circuitry correlates a plurality of communication terminals as a group. The processing circuitry assigns a first transmission right to one of the communication terminals in the group and a second transmission right to one of the communication terminals in the group. The processing circuitry transmits, through a first channel, image data transmitted from the communication terminal which is assigned with the first transmission right to the other communication terminals in the group. The processing circuitry transmits, through a second channel, voice data transmitted from the communication terminal which is assigned with the second transmission right to the other communication terminals in the group. The processing circuitry is configured to permit a single communication terminal to be assigned with both the first and second transmission rights.

Abstract: A controller includes a real-time communication unit, an application communication unit, and a socket management unit. The real-time communication unit communicates with an external node by using a first socket on a basis of a transmission right map indicating a node possessing a transmission right out of multiple nodes.

The socket management unit restricts at least one of transmission of information by the application communication unit to the external node and reception of information by the application communication unit from the external node.

Abstract: A method of delivering a media stream in a network having first and second media servers each capable of delivering segmented media content to a requesting media client. The network provides for HTTP-based delivery of segmented media, and the media client is supported on a client-side device. The method begins by associating the media client with the first media server. As the first server receives from the media client request for media content segments, request times for a given number of the most-recent segments requested are used to generate a prediction, by the first server, of when the media client has transitioned from a start-up or buffering state, to a steady state. In response to a new segment request being received, and upon the first server predicting that the media client has completed a transition to steady state, the new segment request is redirected to the second media server.

Abstract: Systems and methods for automatically upgrading a license in a communication network are provided. In one embodiment, a network device in communication with a license server may be configured with a processing device and a memory device configured to store a computer program having instructions that, when executed, cause the processing device to analyze a communication path between first and second nodes of a communication system and analyze a first license agreement having a first set of constraints regarding communication between the first and second nodes. Responsive to determining that the communication path is not allowable under the first set of constraints of the first license agreement, the instructions may further cause the processing device to upgrade the first license agreement to a second license agreement having a second set of constraints that are less-restrictive than the first set of constraints regarding communication between the first and second nodes.
