Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network service provisioning systems face inefficiencies due to complex deployments, redundant processing, and suboptimal service application order, leading to compromised network throughput and resources.
Innovation Solution
A system that encodes service information in a network-compatible packet header, utilizing MPLS, GRE, or L2TP headers, to facilitate efficient service application and tracking across network nodes, eliminating redundant classifications and optimizing service order.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If packets are analyzed and classified by each network device independently, then services can be applied to packets, but redundant processing occurs and network throughput is compromised
Solution Approach 1:
The patent applies preliminary action by performing packet classification and service determination at the first network device before the packet reaches subsequent devices. The service information is then encoded into the packet header, allowing downstream devices to skip redundant classification and directly apply services based on the pre-encoded information, thus eliminating redundant processing while ensuring reliable service application.
2Ease of operation
If service information is not encoded in packet headers, then network devices can independently process packets, but services are applied in suboptimal order and redundant processing occurs
Solution Approach 1:
The patent implements feedback by encoding service information back into the packet header after classification at the first device. This feedback mechanism provides downstream devices with knowledge of which services have been applied and in what order, enabling them to make informed decisions about whether to process the packet further or skip to the next required service, thereby optimizing service application efficiency while maintaining operational simplicity.
3Adaptability or versatility
If reclassification is performed at each network device, then services can be selectively applied, but application of redundant services occurs and resources are compromised
Solution Approach 1:
The patent extracts the service determination function from each individual network device and consolidates it at the first network device. By taking out the classification and service selection logic from subsequent devices and performing it centrally at the first device, the system eliminates redundant service applications and reduces overall network resource consumption while maintaining the ability to selectively apply appropriate services.

AI summary
A system for selectively applying a service to a packet in a network. In a specific embodiment, the system includes a mechanism for encoding service information in a network-compatible packet header and providing encoded data in response thereto. In a more specific embodiment, the network-compatible header includes a Multi-Protocol Label Switching (MPLS) header, a Generic Route Encapsulation (GRE) header, and/or a Layer-2 Tunneling Protocol (L2TP) header.
