Service Binding MAC Address Replacement for Network Traffic Aggregation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current IP networks face challenges in efficiently managing data traffic with the increasing number of user devices and service providers, particularly in providing higher quality of service without compromising data traffic quantity and routing efficiency, as existing solutions like MPLS result in reduced data traffic and slower routing capabilities.
Innovation Solution
The method and nodes for aggregating data traffic using service bindings over access domains, specifically by creating and enforcing service bindings at access edge nodes, which modify Unicast messages by replacing user device MAC addresses with virtual MAC addresses to manage data traffic between user domains and service provider domains.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If MPLS is used to provide higher quality of service, then quality of service is improved, but data traffic quantity is reduced and routing capabilities are slowed
Solution Approach 1:
The patent segments data traffic into different types (service provider traffic and other traffic) and applies different handling mechanisms. Service provider traffic is aggregated and forwarded without MPLS label switching, while other traffic continues to use traditional routing. This segmentation allows QoS improvement for specific traffic without compromising overall network productivity.
Solution Approach 2:
The patent extracts service provider traffic from the general data traffic flow and handles it separately through service bindings. By taking out this specific traffic type and applying dedicated service bindings, the system improves QoS for these flows without subjecting them to the overhead that would reduce overall data traffic quantity and routing speed.
2Quantity of substance
If the number of user devices and service providers increases, then network capacity is improved, but routing efficiency is reduced
Solution Approach 1:
The patent merges multiple service bindings into a single aggregated data flow that is forwarded without individual label switching operations. By combining multiple service provider traffic flows into a unified service binding, the system supports an increasing number of devices and service providers while maintaining routing efficiency through reduced per-packet processing overhead.
Solution Approach 2:
The patent creates a universal service binding mechanism that can handle multiple service providers and user devices through a common framework. This multi-functional approach allows the same service binding infrastructure to serve numerous devices and providers, scaling network capacity without proportionally increasing routing complexity.
3Reliability
If service bindings are created to manage data traffic, then quality of service is improved, but device complexity is increased
Solution Approach 1:
The patent implements self-service mechanisms where access edge nodes automatically create and enforce service bindings based on service requests. The system performs self-configuration and self-management of service bindings without requiring complex manual configuration, thereby improving QoS while minimizing the operational complexity burden on network administrators.
Solution Approach 2:
The patent performs preliminary actions by pre-establishing service bindings at access edge nodes before data traffic needs to be managed. Service bindings are created in advance based on service requests, allowing the system to handle quality of service requirements efficiently without adding complexity during actual data traffic processing.

AI summary
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.
