Abstract:
The present invention relates to a method and nodes for managing service bindings over an access domain. For doing so, an access edge node is introduced in the access domain between a plurality of service providers and user domains, and an access node is introduced between the user domains and the access domain. The access edge node creates, modifies and removes service bindings and informs the access node of those creations, modifications and removals. Each service binding binds one of the user domain, the access node and the access edge node on data traffic handling over the access domain between the user domain and the service provider domain. More particularly, the service binding associates the user domain to a Virtual Local Area Network (VLAN) for the service provider domain on the access domain, controlled by the access edge node.
Abstract:
A method and an access domain node identify and manage a type of service offered by a service provider to user domains. A service template is prepared by the service provider, comprising an address of a server and a protocol identifier, as well as policies for controlling traffic for the service. Upon set up of a connection between a user domain and the service provider, an address of the user domain is added to the service template to produce a service flow management set. Every data packet exchanged between the user domain and the server, in either direction, is related to a service data flow for a given service type by checking for a match between a source address, a destination address, and a protocol type contained therein, with an appropriate service type. Policies from the service flow management set are used to manage the flow of data packets.
Abstract:
The present invention provides a method and nodes for authenticating nomadic users accessing service providers. An access edge node authenticates nomadic users when service requests are received therefrom. The access edge node hosts a plurality of service agents, where each service agent comprises transport parameters for access to one of the service providers. Upon receipt at the access edge node of a service request message identifying a service provider and a nomadic user, an identity of the nomadic user is authenticated and verification is made that a service agent corresponding to the identified service provider exists. If both the authentication and the verification are positive, an authenticated service binding is created, connecting the nomadic user, the service provider and the transport parameters. Then, an access node providing access to the nomadic user for which the service request message was received is informed of the authenticated service binding.
Abstract:
The present invention relates to a method and nodes for performing data traffic aggregation over an access domain using service bindings. Upon receipt of a service request related message at an access edge node for a first device of a user domain, the service request related message identifying the first device of the user domain and one of the service provider domains, a service binding is created at the access edge node. The service binding rules data traffic between the first device of the user domain and the service provider domain by committing an access node serving the user domain and the access edge node in a manner of managing data traffic therebetween over the access domain. An access node serving the user domain for which the service request related message is received is informed of the created service binding. The created service binding is enforced at the access node and the access edge node for data traffic over the access domain between the first device of the user domain and the service provider domain by removing a user device MAC address from Unicast messages exchanged therebetween over the access domain and replacing with a virtual MAC address recognized by the access node and the access edge node.
Abstract:
The present invention relates to a method and nodes for aggregating data traffic over an access domain carrying data traffic between a plurality of service providers and user domains. For doing so, an access edge node is introduced in the access domain between the plurality of service providers, and the user domains. The access edge node hosts a plurality of service agents, where each service agent controls a Virtual Local Area Network over the access domain for one of the service providers. Upon receipt of a service request related message identifying one of the service provider domain and one of the user domain, verification is made at the access edge node to identify whether a service agent corresponding to the service provider identified in the service request related message exists. If the verification is positive, the user domain is added to the a Virtual Local Area Network corresponding to the requested service provider through the creation of a service binding at the access edge node. Then, an access node providing access to the access domain to the user domain for which the service request related message was received is informed of the service binding, and the data traffic between the user domain and service provider identified in the service request related message is aggregated over the access domain in accordance with the created with the created service binding.
Abstract:
Several services offered by distinct service providers can be accessed from a single user device, through one or more gateways. To ensure quality of service control, each service provider allocates a distinct address to the user device. Distinct forwarding information bases and service mappings are defined at the user device, comprising one such forwarding information base for each service provider and one service mapping for each service type offered by a given service provider. The separate addresses allocated to the user device are related to the separate service mappings. Distinct virtual local area networks (VLANs) are defined, each containing one of the forwarding information base and one of the service mappings. Tags added to packets by the gateways and arriving at the user device are used to link the packets to the proper service provider and to the proper service type.
Abstract:
Systems and methods according to these exemplary embodiments provide for methods and systems for negotiating resources in a communication system. One exemplary method includes transmitting, by a service manager, a request for a service, wherein the service request either explicitly provides, or implicitly refers to, a list of a plurality of service options for providing the service. Additionally, a resource manager can receive the transmission request from a service manager and process the request based upon either the explicitly transmitted list of service options or the reference to a list of service options.
Abstract:
The present invention relates to a method, an access node, an access edge node and a decentralized node for aggregating data traffic over an access domain. The decentralized node corresponds to one of the service providers, and is located in closer proximity with user domains to be serviced. The decentralized node maintains over the access domain one or several Virtual Local Area Networks, for aggregating thereon data traffic to be exchanged with the user domains, on behalf of the service provider domain. To allow proper aggregation of the data traffic, service bindings are created and stored at the access edge node, and further stored at the decentralized node and at the access node. Therefore, aggregation of the data traffic between the decentralized node and the user domains over the access domain is performed in accordance with the created service bindings.
