Cloud Exchange IP-VPN for Low-Latency Traffic Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network service providers (NSPs) based community of interest (COIN) connections require multiple peer-to-peer connections and traverse wide area networks, leading to high latency, security concerns, and increased costs due to the need for costly private connections.
Innovation Solution
A cloud exchange-based COIN uses a programmable network platform to configure virtual routing and forwarding instances within a data center, establishing an Internet Protocol-Virtual Private Network (IP-VPN) for direct traffic exchange among participants, eliminating the need for separate connections and leveraging a centralized location for reduced latency and enhanced security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If NSP-based COIN connections are used, then connectivity between participants is established, but latency increases due to wide area network traversal
Solution Approach 1:
The patent merges multiple participant networks into a single local area network environment within the data center, eliminating the need for wide area network traversal. All COIN participants are interconnected through local switching fabric, consolidating what would otherwise require multiple remote connections into a unified local network infrastructure.
Solution Approach 2:
The patent introduces a cloud exchange platform as an intermediary that provides local networking infrastructure within the data center. This intermediary enables direct peer-to-peer connections between participants without requiring external NSP wide area network paths, acting as a local mediator that replaces remote routing.
2Reliability
If multiple peer-to-peer private connections are established for COIN participants, then secure connectivity is achieved, but costs increase due to multiple costly private connections
Solution Approach 1:
The patent makes a single private connection to the cloud exchange platform serve multiple functions simultaneously. One connection provides universal access to all COIN participants through the local network infrastructure, replacing the need for multiple dedicated point-to-point connections. The single connection acts as a universal gateway to the entire COIN network.
Solution Approach 2:
The patent combines multiple separate private connection requirements into a single consolidated connection. Instead of requiring N*(N-1)/2 individual private connections between N participants, the system merges all connectivity needs into N individual connections to the cloud exchange platform, dramatically reducing the total number of expensive private connections required.
3Adaptability or versatility
If NSP-based COIN connections are used, then participant interconnection is enabled, but device complexity increases due to multiple connection requirements
Solution Approach 1:
The patent implements automated connection provisioning through the cloud exchange platform, which automatically configures network paths and routing between participants. The system provides self-service capabilities where the platform handles connection establishment, routing configuration, and network management without requiring manual configuration of complex peer-to-peer connections by each participant.
Solution Approach 2:
The cloud exchange platform acts as an intermediary that manages the complexity of participant interconnections. It provides a simplified interface for participants to join the COIN while handling all the complex routing, switching, and network configuration in the background, shielding participants from the underlying complexity.
4Adaptability or versatility
If wide area network paths are used for COIN traffic, then geographic distribution is supported, but performance deteriorates due to network traversal
Solution Approach 1:
The patent segments network traffic into local COIN traffic and external traffic. COIN participant traffic is segmented and kept within the local data center network infrastructure, preventing it from traversing wide area networks. Only necessary external communications leave the data center, while internal COIN communications remain local for optimal performance.

AI summary
In general, techniques are described for interconnecting, within a cloud exchange, multiple entities in a community of interest by which the multiple entities can interact as peers over a private, multi-party connectivity service for direct traffic exchange. In one example, a cloud exchange includes a layer three (L3) autonomous system located within a data center, wherein the L3 autonomous system is configured: with a plurality of attachment circuits between the cloud exchange and respective networks co-located within the data center, wherein each of the networks is associated with a different customers of a cloud exchange provider for the cloud exchange; with an Internet Protocol Virtual Private Network (IP-VPN) for a community of interest that includes each of the plurality of customers; and to switch, using the IP-VPN and based on destination addresses of packets received from any of the networks, the packets to any other of the networks.
