MAP Node Autonomous Provisioning Without DHCP
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Mapping of Address and Port (MAP) provisioning relies on Dynamic Host Configuration Protocol version 6 (DHCPv6), which requires multiple messages with a DHCP server, posing challenges in scenarios where a DHCP server is unavailable or not accessible.
Innovation Solution
The system facilitates MAP provisioning by using a service configuration manager to provide configuration files with Type-Length-Value (TLV) encodings that allow a MAP node to autonomously configure itself for MAP-T and MAP-E operations, eliminating the need for DHCP server interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If DHCPv6 is used for MAP provisioning, then configuration can be automated through standardized protocol, but provisioning fails when DHCP server is unavailable
Solution Approach 1:
The MAP node performs self-provisioning by autonomously generating its own configuration parameters (IPv4 address, IPv6 address, port mappings) without requiring external DHCP server interaction. The node uses local algorithms to create these parameters, making the provisioning process independent of external infrastructure.
Solution Approach 2:
The system pre-generates configuration parameters and embedding rules before actual MAP operation is needed. The node has ready-made templates and algorithms for address generation and port mapping configured in advance, allowing immediate operation without waiting for DHCP server responses.
2Ease of manufacture
If multiple DHCPv6 messages are exchanged for provisioning, then configuration can be standardized, but provisioning time increases
Solution Approach 1:
The invention extracts the essential provisioning functionality from the DHCPv6 protocol sequence, keeping only the critical address and port mapping configuration elements. By removing the multi-message exchange requirement and implementing direct configuration delivery, the system maintains standardization while eliminating time-consuming protocol handshakes.
Solution Approach 2:
The system skips the traditional multi-step DHCPv6 message exchange process and directly provisions the MAP node with necessary configuration parameters. This rushing through the provisioning process in a single action eliminates the time loss associated with multiple message exchanges while maintaining configuration completeness.
3Adaptability or versatility
If DHCP server is required for MAP provisioning, then centralized control is maintained, but system availability decreases
Solution Approach 1:
The provisioning function is segmented from the centralized DHCP server model and distributed to individual MAP nodes. Each node becomes an independent provisioning unit capable of autonomous configuration, eliminating the single point of failure represented by the DHCP server while maintaining standardized configuration practices.
Solution Approach 2:
The system changes the fundamental parameter of provisioning control from centralized (DHCP server-managed) to distributed (node-autonomous). This parameter change enables the system to adapt to environments where centralized servers are unavailable, improving reliability while maintaining configuration standardization through embedded rules.

AI summary
Mapping of Address and Port (MAP) provisioning of a device to enable exchange of Internet Protocol version 4 (IPv4) packets with an IP version 6 (IPv6) domain is contemplated. The MAP provisioning may be sufficient to facilitate provisioning of a router to process IPv4 packets for exchange with the IPv6 domain of an associated modem.
