Layer Two Tunnel for Device Identification in Home Gateways
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network configurations at customer premise locations, where a home gateway manages communication with user devices using a single TCP/IP address, limit the ability for external networks to identify and provide services to individual devices, restricting features and services.
Innovation Solution
Implementing a Layer Two tunnel from a home gateway to a cloud-based server, allowing the server to access and control locally unique addresses of user devices, enabling device-specific services and efficient allocation of globally unique addresses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single TCP/IP address is assigned to the home gateway for managing communication, then network management is simplified, but the ability to identify and provide services to individual user devices is lost
Solution Approach 1:
A cloud-based server acts as an intermediary between external networks and user devices at the customer premise. The server receives communications intended for specific user devices, determines the target device identity, and routes the communication through the home gateway to the appropriate device. This mediator enables device-specific service provision while keeping the home gateway configuration simple with a single TCP/IP address.
2Adaptability or versatility
If device-specific services are implemented, then service personalization is improved, but network complexity increases
Solution Approach 1:
The complex functionality for device identification and service management is extracted from the home gateway and relocated to a cloud-based server. The home gateway is reduced to a simple pass-through device that forwards communications without needing to perform complex identification or service management functions. This extraction enables service personalization while keeping the local network configuration simple.
3Ease of operation
If the home gateway performs all processing functions, then local control is improved, but cloud-based service capabilities are limited
Solution Approach 1:
The system transitions from purely local processing at the home gateway to a distributed architecture that operates across multiple dimensions - local forwarding at the gateway and cloud-based processing at the server. This dimensional shift enables both local control through the gateway's forwarding function and extensive cloud service capabilities through the server's processing power and connectivity.

AI summary
A Layer Two Tunnel may be established between one or more user devices and a tunnel aggregator device via a home gateway. By establishing the Layer Two Tunnel, the tunnel aggregator and other entities of an access network, such as a multi-system operator (MSO) network, may be configured to identify individual user devices at a customer premise. As a result, the network operator may be able to offer individual user device and user based services. Additionally, operations, such as DHCP, NAT, etc., that may otherwise be conducted at a customer premise, such as by a home gateway, may be performed at the MSO and/or in the cloud.
