Channel Data Encapsulation for Multi-Tenant Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In cloud computing datacenters, especially multi-tenant environments, IP address conflicts and loss of routing information in TCP/IP packets lead to challenges in routing data to the correct server and security microservices, resulting in inefficient data transmission and processing.
Innovation Solution
Implementing channel data encapsulation systems that encapsulate network packets in channel data encapsulation packets with an encapsulation header containing routing and security context, allowing for efficient routing and processing across a hierarchy of security microservices, even when original packet information is lost.

Engineering Contradiction Analysis
1Adaptability or versatility
If TCP/IP packets are used for data transmission in multi-tenant datacenters, then data can be transmitted over public networks, but routing information is lost and IP address conflicts occur making it impossible to route data to the correct server
Solution Approach 1:
The patent encapsulates original TCP/IP packets within channel data encapsulation packets that contain additional routing information. The nested structure allows the inner packet to retain its original TCP/IP format while the outer packet provides the missing routing context through encapsulation headers containing channel identifiers and routing data.
Solution Approach 2:
The patent introduces channel data encapsulation packets as an intermediary layer between the original TCP/IP packets and the network routing infrastructure. This intermediary carries additional routing information in its header, enabling routers to correctly forward data to the intended server without modifying the original TCP/IP packet structure.
2Reliability
If channel data encapsulation packets are implemented, then routing information is preserved and packets can be routed correctly, but network packet size increases
Solution Approach 1:
The patent segments the routing information into a separate encapsulation header that is added to the channel data encapsulation packet. This segmentation allows the routing metadata to be organized efficiently and only the necessary fields to be included, minimizing the overhead added to the original packet.
3Productivity
If traditional packet-by-packet processing is used, then each packet can be processed independently, but network routing load is high and processing efficiency is low
Solution Approach 1:
The patent merges multiple related packets into a single channel data encapsulation packet by using channel identifiers to group packets belonging to the same data channel. This combining approach allows the network to process channels rather than individual packets, significantly reducing routing lookup operations and improving processing efficiency.
Solution Approach 2:
The channel data encapsulation packet structure serves multiple functions: it provides routing information for correct server delivery, maintains packet grouping for efficient channel-based processing, and preserves the original TCP/IP packet structure for application compatibility. This multi-functionality reduces the need for separate processing mechanisms.

AI summary
Systems and methods are disclosed that relate to network security to monitor and report threats in network traffic of a datacenter. For example, one embodiment discloses a method of receiving, by a first security microservice, a first channel data encapsulation packet encapsulating a first encapsulation context and a first encapsulated data, performing a security service on the first encapsulated data using the first encapsulation context, transmitting by the first security microservice a second channel data encapsulation packet to a second security microservice, wherein the second channel encapsulation packet comprises a request for security services, receiving by the first security microservice a response from the second security microservice comprising a second security microservice context, a second security microservice timestamp, and a second security microservice load. The first security microservice further generates a timestamp and a load included in a response to the first channel data encapsulation packet.
