A device may receive a set of design parameters for a network service. The set of design parameters may include information that identifies one or more network functions associated with the network service. The device may determine attribute information associated with a plurality of virtual network functions (VNFs). A VNF, of the plurality of VNFs, may be configurable to perform at least one network function of the one or more network functions. The device may generate a network service design, associated with providing the network service, based on the set of design parameters and the attribute information. The network service design may include information identifying one or more VNFs, of the plurality of VNFs, that are capable of providing the network service in accordance with the set of design parameters. The device may provide information associated with the network service design.

Automated generation of a network service design

An apparatus may (1) receive, at the service provider's network, at least one flow of network traffic from a remote device included in a user's private network, (2) identify, within the flow of network traffic, at least one potentially non-unique private address that represents the remote device with respect to the user's private network, (3) determine, at least one unique routable address that represents the remote device with respect to the service provider's network based at least in part on a network interface assigned to the user's private network, the potentially non-unique private address, and the address-translation table, and then (4) translate, in response to determining the unique routable address, the potentially non-unique private address to the unique routable address to facilitate routing return network traffic to the remote device in connection with the flow of network traffic. Various other apparatuses, systems, and methods are also disclosed.

Systems and methods for virtualizing customer-premises equipment

A computer-implemented method for virtualizing customer-premises equipment may include (1) receiving, at a service provider's network, at least one flow of network traffic from a remote device included in a user's private network, (2) identifying, within the flow of network traffic, at least one potentially non-unique private address that represents the remote device with respect to the user's private network, (3) determining at least one unique routable address that represents the remote device with respect to the service provider's network based at least in part on a network interface assigned to the user's private network and the potentially non-unique private address, and then (4) translating the potentially non-unique private address to the unique routable address to facilitate routing return network traffic to the remote device in connection with the flow of network traffic. Various other systems, methods, and computer-readable media are also disclosed.

In general, the invention is directed to techniques for offloading per-subscriber traffic management from an access gateway to one or more upstream service nodes within a service provider network. For example, as described herein, an upstream service node receives a new packet flow for a subscriber and sends packet flow information, such as a network address, to a session and resource controller (SRC). The SRC maintains a table of subscriber attachment sessions and maps the packet flow information to a subscriber attachment session in the table to obtain a subscriber identifier for a subscriber. The SRC then determines subscriber-specific services to be applied to subscriber data traffic, transforms the services to a set of one or more enforcement policies, and returns the enforcement policies to the service node. In turn, the service node applies the enforcement policies for the subscriber-specific services to the subscriber data traffic in the packet flow.

Subscriber-based network traffic management

A service deployment device responds to events originating internally or in a network using a set of condition/action rules. The condition/action rules are defined in terms of business-level information. A rules engine in the service deployment device translates the network events to business information and uses a forward-chaining algorithm to evaluate conditions associated with the rules. Based on the evaluation, the service deployment device enables actions associated with the rules. An enterprise using the service deployment device uses the condition/action rules to deploy business policies in the network.

Network service management using customizable business-level rules

A network testing environment includes a control server and a testing cluster composed of one or more load generating devices. The load generating devices output network communications in a non-deterministic manner to model real-world network users and test a network system. The load generating devices operate in accordance with probabilistic state machines distributed by the control server. The probabilistic state machines model patterns of interaction between users and the network system.
