BI-DIRECTIONAL TUNNEL PROBING IN A MULTI-REALM NETWORK - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240348475 titled 'BI-DIRECTIONAL TUNNEL PROBING IN A MULTI-REALM NETWORK

Simplified Explanation: The abstract discusses extending bi-directional tunnel probing to multi-realm networks, allowing for probing in a multi-realm network using specific labels and headers.

Key Features and Innovation:

  • Bi-directional probing in a multi-realm network utilizes forward tunnel labels, reverse tunnel labels, and IP packet headers.
  • Penultimate hop popping removes outermost labels in a specific order.
  • The use of a specific identifier (SID) helps return the probe packet to the originating realm.
  • No SID is required for intra-realm probing.
  • IP packet headers are used to return the probe packet if the reverse tunnel label is missing.

Potential Applications: This technology can be applied in complex network environments where bi-directional probing is necessary for troubleshooting and monitoring network performance.

Problems Solved: This technology addresses the need for efficient and effective bi-directional probing in multi-realm networks, improving network visibility and troubleshooting capabilities.

Benefits:

  • Enhanced network monitoring and troubleshooting capabilities.
  • Improved efficiency in identifying and resolving network issues.
  • Better visibility into network performance across multiple realms.

Commercial Applications: Potential commercial applications include network management systems, telecommunications companies, and large-scale enterprises requiring advanced network monitoring and troubleshooting capabilities.

Prior Art: Readers can explore prior research on bi-directional tunnel probing, multi-realm networks, and network troubleshooting techniques to understand the evolution of this technology.

Frequently Updated Research: Stay updated on advancements in network monitoring tools, tunneling protocols, and network troubleshooting methodologies to enhance the effectiveness of bi-directional probing in multi-realm networks.

Questions about Bi-Directional Tunnel Probing in Multi-Realm Networks: 1. How does bi-directional probing in multi-realm networks differ from traditional network probing methods? 2. What are the key components of a probe packet used in bi-directional tunnel probing in multi-realm networks?


Original Abstract Submitted

bi-directional tunnel probing in a network may be extended to multi-realm networks, providing bi-directional probing in a multi-realm network. bi-directional probing uses probe packets with a forward tunnel label, a reverse tunnel label, and an ip packet header. bi-directional probing in a multi-realm network uses a forward tunnel label, an sid, a reverse tunnel label, and an ip packet header. penultimate hop popping strips the outermost labels in a specific order. the sid gets the probe packet back into the originating realm, and the reverse tunnel label returns the probe packet along the reverse direction of the tunnel. no sid is needed for intra-realm probing, and the ip packet header is used to return the probe packet if the reverse tunnel label is absent.
