Segmentation Identification for Multitenant Packet Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In data center networks, especially in multitenancy environments, existing communication protocols face challenges in efficiently transmitting packets to destination nodes due to complexities associated with service instance designation, network node identification, and virtual local area network management, leading to potential incorrect routing and increased network complexity.
Innovation Solution
The solution involves using a receiving node that identifies a packet with an internet protocol address and segmentation identification, selects a corresponding virtual routing and forwarding table, and transmits the packet to the destination node, thereby avoiding unnecessary constructs and complexities by utilizing segmentation identification to distinguish between network nodes with the same IP address.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If traditional communication protocols are used in data center networks, then packet transmission can be performed, but network complexity increases due to unnecessary constructs for serviceinstance designation, network node identification, and virtual local area network management
Solution Approach 1:
The patent applies segmentation by dividing the network identification space into traditional IP address space and segmentation identification space. The segmentation identification field is introduced as a separate component that segments the identification function from the IP address, allowing independent management of network nodes and virtual networks without increasing overall protocol complexity.
Solution Approach 2:
The patent extracts the service instance designation and virtual network identification functions from the traditional IP header and relocates them to a dedicated segmentation identification field. This extraction removes unnecessary constructs from the packet transmission path while maintaining reliable routing through the segmented identification mechanism.
2Adaptability or versatility
If multiple virtual local area networks are supported, then multitenancy capability is improved, but packet routing becomes more complex and incorrect routing may occur
Solution Approach 1:
The patent adds another dimension to network identification by introducing the segmentation identification field alongside the traditional IP address. This dimensional expansion allows the system to distinguish between different virtual networks and service instances without complicating the routing process, as the segmentation identification provides an additional layer of differentiation that simplifies multitenancy management.
3Measurement precision
If segmentation identification is introduced to distinguish nodes with same IP address, then routing accuracy is improved, but packet header structure becomes more complex
Solution Approach 1:
The patent merges the IP address and segmentation identification into a unified packet handling mechanism where both fields work together to identify the destination node. The segmentation identification is integrated into the existing packet structure in a way that maintains compatibility with traditional IP protocols while providing enhanced identification capability, thus improving accuracy without proportionally increasing complexity.

AI summary
Packet transmission techniques are disclosed herein. An exemplary method includes receiving a packet that identifies an internet protocol (IP) address assigned to more than one destination node; selecting a virtual routing and forwarding table based, at least in part, on a segmentation identification in the packet; identifying a designated destination node in the packet based, at least in part, on the selected virtual routing and forwarding table; and transmitting the packet to the designated destination node.
