Building Aggregation System Carrier-Tagged Flow Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current access networks face challenges in providing cost-effective services to customers with varying bandwidth and quality of service needs, as they require separate provisioning and handling of different types of communication services, leading to complex and costly network elements that lack flexibility in accommodating rapid changes or new service types.
Innovation Solution
The implementation of a building aggregation system that uses service emulation instances, such as pseudowires and virtual local-area networks, to aggregate and manage traffic from multiple service types, employing carrier-tagged flows with service emulation mapping identifiers to simplify switching and routing, allowing for efficient handling of various protocols and protocols without needing to examine the content of customer data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate provisioning and handling of different types of communication services is used, then specific service requirements can be met, but network element complexity and cost increase
Solution Approach 1:
The patent implements a universal access network platform that can handle multiple service types (voice, data, video, mobile) through a common infrastructure. The network uses service-aware routing and virtualization to provide multi-functional capabilities, allowing a single network element to serve diverse services without requiring separate dedicated infrastructure for each service type.
Solution Approach 2:
The patent introduces a service awareness mechanism that acts as an intermediary between the physical network infrastructure and service requirements. This mediator layer maps service requests to appropriate physical resources, enabling flexible service provisioning without direct complex interactions between service types and physical hardware.
2Ease of manufacture
If traditional access network infrastructure is used, then existing facilities can be leveraged, but flexibility to accommodate rapid changes or new service types is limited
Solution Approach 1:
The patent implements dynamic service provisioning capabilities that allow the network to adapt to changing service requirements in real-time. The system uses dynamic routing, virtualization, and software-defined networking to enable rapid deployment of new services and modification of existing ones without physical infrastructure changes, maintaining flexibility while utilizing existing facilities.
3Ease of operation
If service-aware routing with carrier tags is implemented, then traffic aggregation and switching is simplified, but network element processing requirements increase
Solution Approach 1:
The patent extracts service identification and routing logic from the physical network infrastructure and places it in a separate service awareness layer. By separating these functions, the physical network elements only need to process simple carrier-tagged traffic, while the complex service-aware routing is handled by virtualized functions, reducing the processing burden on individual network elements.

AI summary
A system and method is provided for managing access communications between the service edge of a communications service provider and a customer. Access communications are carried in the form of carrier-tagged flows, the communications traffic being appended with carrier tags having significance to handling of the traffic through access network elements. A building aggregation system is provided which couples to customer premise equipment and interfaces customer flows to carrier-tagged flows used in the access network.
