Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current telecommunications networks face challenges in efficiently supporting various types of services and aggregating traffic in access networks, requiring multiple hardware configurations and leading to the need for frequent replacements of switching equipment.
Innovation Solution
A termination point in the access network is introduced, which acts as an 'off-ramp' for aggregated communications, enabling efficient conversions between transport types and embedding switching functionality within the termination point, allowing for the use of pseudowire endpoints and a switching module to interconnect and convert flows for different core networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional switching equipment is used to support multiple service types, then service versatility is achieved, but device complexity and need for hardware replacement increase
Solution Approach 1:
The patent introduces a termination point as an intermediary component that handles protocol conversions and service aggregations. Instead of requiring complex switching equipment at every node, the termination point acts as a mediator between access network elements and core networks, performing protocol translations and flow aggregations centrally. This reduces the complexity of individual devices while maintaining versatility across multiple service types.
Solution Approach 2:
The termination point is designed as a multi-functional device that can handle multiple service types (frame relay, ATM, broadband, voice) through a single unified architecture. By implementing universal protocol handling capabilities within the termination point, the system eliminates the need for separate specialized switching equipment for each service type, thereby reducing overall device complexity while maintaining adaptability.
2Adaptability or versatility
If access network elements perform switching functions, then service flexibility is improved, but device complexity increases
Solution Approach 1:
The patent extracts switching and protocol conversion functions from individual access network elements and consolidates them into a centralized termination point. By taking out these complex functions from distributed switches and placing them in a dedicated termination point, the access network elements become simpler while the system maintains service flexibility through the termination point's aggregation and routing capabilities.
3Adaptability or versatility
If multiple hardware configurations are used for different services, then service support is comprehensive, but ease of manufacture and deployment deteriorates
Solution Approach 1:
The termination point implements a universal platform that supports multiple service types through a single hardware and software architecture. By designing the termination point to handle frame relay, ATM, broadband, and voice services through unified protocol processing, the system eliminates the need for different hardware configurations for each service type, thereby simplifying manufacturing and deployment processes.

AI summary
Apparatus and method for providing a termination point for service emulation instances in an access network is provided. In an embodiment, the service emulation instances are implemented utilizing, for example, pseudowires. Communications to and from the access network are aggregated and transmitted via one or more pseudowires to a service emulation instance terminator. The service emulation instance terminator converts the traffic to its native form and, if necessary, converts the traffic to a different type of format or service. The service emulation instance terminator then frames the traffic for the appropriate type of service and transmits the traffic to the service edge. Traffic received from the service is removed prepended with a pseudowire label and aggregated with other traffic. The aggregated traffic is transmitted to the customer via the access network. If necessary, an interworking function may convert the traffic from one type of service to another type of service. Further, functionalities of equipment such as frame relay switching or Asynchronous Transfer Mode (ATM) switching may be realized in the service emulation instance terminator.
