Inter-SEPP Payload Compression Handshake for Predictable Throughput
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In inter-network connectivity scenarios, existing systems face unpredictable network performance due to payload size increase caused by decompression and reformatting at gateways, leading to inefficient data transmission and lack of defined procedures for determining payload compression at intermediate nodes.
Innovation Solution
Implementing a data compression mechanism on the end-to-end inter-SEPP data plane connection, where payload compression is negotiated during a handshake process, ensuring consistent and predictable network performance by determining compression methods based on intermediate IPX capabilities and support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If payload decompression and reformatting is performed at gateways, then interoperability between different networks is achieved, but payload size increases leading to unpredictable network performance
Solution Approach 1:
The patent applies preliminary action by negotiating and establishing payload compression parameters during the control plane connection setup phase, before actual data transmission begins. This allows compression methods to be predetermined and agreed upon by both gateways, ensuring that payload data can be transmitted in compressed form without requiring decompression and reformatting at intermediate gateways, thus avoiding payload size increase while maintaining interoperability.
2Productivity
If payload compression is not negotiated, then simple data transmission is used, but network performance becomes unpredictable due to payload size fluctuations
Solution Approach 1:
The patent implements feedback by establishing a bidirectional negotiation mechanism during the handshake process where both gateways exchange information about their compression capabilities and agree on a common compression method. This feedback loop ensures that both ends of the data plane connection are aware of and configured for the same compression parameters, enabling consistent compressed transmission and predictable network performance.
3Productivity
If compression negotiation occurs during handshake, then payload transmission efficiency is improved, but control plane connection establishment complexity increases
Solution Approach 1:
The patent applies universality by integrating the compression negotiation functionality into the existing control plane connection establishment handshake process. Rather than creating a separate complex negotiation protocol, the compression parameters are negotiated as part of the standard handshake procedures that gateways already perform for connection setup, thereby adding compression capability without significantly increasing overall system complexity.

AI summary
According to an example aspect of the present invention, there is provided an apparatus configured to initiate a handshake process configured to establish a control plane connection prior to establishing an associated data plane connection from the apparatus to a gateway node in second network, the apparatus being in a first network distinct from the second network, indicate during the establishing of the control plane connection that compression of payload communicated over the data plane connection is requested, and wherein the data plane connection to the gateway node traverses at least one intermediate internet protocol exchange.
