Network Switch Protocol Translation via Canonical Packet Format
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network switch protocol translation methods, such as N-to-N protocol mapping, are complex and inefficient, leading to resource imbalances and increased complexity when adding new services or protocols, as they require implementing all possible uni-directional protocol translations, which is not linear with the number of supported protocols.
Innovation Solution
Implementing an N-to-1 protocol mapping mechanism during data ingress and a 1-to-N protocol mapping mechanism during data egress, using a Canonical Packet Format (CPF) to simplify protocol translations and distribute processing tasks between ingress and egress, reducing the number of required translations from N2 to 2N and allowing for easier addition of new services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If N-to-N protocol mapping with all N2 possible protocol translations is implemented, then complete protocol translation capability is achieved, but development complexity increases quadratically with N
Solution Approach 1:
The patent introduces a Canonical Packet Format (CPF) as an intermediary representation between different protocol formats. Instead of implementing direct translations between all protocol pairs, each protocol is translated to and from the canonical format, reducing the number of translation paths from N2 to 2N. The CPF serves as a universal intermediate representation that simplifies the translation architecture.
Solution Approach 2:
The patent segments the protocol translation process into two distinct phases: ingress translation (from specific protocol to canonical format) and egress translation (from canonical format to specific protocol). This segmentation allows independent optimization of each translation direction and reduces the overall complexity by avoiding the need to implement all possible direct protocol-to-protocol translation paths.
2Reliability
If protocol translations are mainly performed during data ingress, then ingress processing is comprehensive, but resource stress increases during ingress and resource waste occurs during egress
Solution Approach 1:
The patent implements dynamic protocol translation that adapts to the direction of data flow. During ingress, translations are performed from specific protocols to the canonical format. During egress, translations are performed from the canonical format to specific protocols. This dynamic approach ensures that translation resources are actively utilized in both directions, eliminating resource waste while maintaining processing completeness.
Solution Approach 2:
The patent ensures continuous useful action by performing protocol translations at both ingress and egress points. Rather than concentrating all translation work at one point in the data flow, the system maintains active translation capabilities throughout the data path, ensuring that resources are productively engaged regardless of the translation direction required.
3Adaptability or versatility
If N-to-N protocol mapping is implemented, then all protocol combinations are supported, but adding a new service requires implementing an additional 2N protocol translations
Solution Approach 1:
The patent creates a universal Canonical Packet Format that can represent multiple protocol types. This universal format allows the system to support new services and protocols by simply adding translation paths to and from the canonical format, rather than requiring comprehensive reconfiguration of all existing translation paths. The CPF acts as a universal interface that simplifies service integration.

AI summary
A system and method are disclosed for processing a packet. Processing the packet comprises receiving the packet; translating the packet from a first protocol-specific format to a canonical packet format; translating the packet from the canonical packet format to a second protocol-specific format; and forwarding the packet.
