Switch-Based Service-Aware Routing for Edge Cloud Deployment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The deployment of edge cloud services is hindered by the configuration of customer-premises equipment (CPE), which requires significant space and power, making it difficult to set up in equipment rooms with limited resources.
Innovation Solution
A data transmission method that uses a switch to determine routing information based on the service type of data packets, allowing them to be transmitted through specific links without the need for CPE, thereby reducing space requirements and improving site deployment efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If CPE is deployed at each site to ensure data transmission quality, then transmission reliability is improved, but device complexity and space requirements increase
Solution Approach 1:
The patent extracts the link selection function from the CPE device and relocates it to the switch device. The switch identifies service types of data packets and selects appropriate transmission links based on service requirements, while the CPE only performs simple packet forwarding. This extraction eliminates the need for complex CPE configuration and reduces deployment difficulty while maintaining transmission reliability.
Solution Approach 2:
The patent merges the link selection functionality into the switch device, combining routing capabilities with service type identification. The switch now performs both traditional switching functions and service-aware link selection, eliminating the need for separate CPE configuration and simplifying the overall system architecture.
2Reliability
If CPE is deployed at each site to ensure data transmission quality, then transmission reliability is improved, but the area of equipment room increases
Solution Approach 1:
By extracting the link selection function from CPE to the switch, the patent eliminates the need for additional CPE devices in equipment rooms. The existing switch is enhanced with service-aware routing capabilities, thereby maintaining transmission quality without increasing equipment room area.
3Reliability
If CPE is deployed at each site to ensure data transmission quality, then transmission reliability is improved, but power consumption increases
Solution Approach 1:
The patent extracts the intelligent link selection function from power-consuming CPE devices and implements it in the switch, which already has active processing capabilities. This eliminates the need for additional CPE power consumption while maintaining transmission quality through service-aware routing.

AI summary
A data transmission method for to a data center including a first site and a second site is disclosed. According to the data transmission method, after obtaining a first data packet sent by a virtual machine at the first site, a switch at the first site identifies a service type of the first data packet, and determines routing information of the first data packet based on the service type of the first data packet; and after determining the routing information, the switch sends the first data packet based on the routing information, where the routing information is used to indicate a bearer link for transmitting the first data packet, and a link through which the first data packet is transmitted to the second site is the bearer link. In this way, the first data packet may be transmitted through a link that corresponds to the service type of the first data packet.
