Description

Technical Field

[0001] The present invention relates to the field of network computing technology, and in particular, to a cross-region CSPF network computing system that extends IGP. Background Art

[0002] The cross-region CSPF network computing system that extends IGP involves several key background technologies and concepts, which are usually used to optimize routing calculations, cross-domain network management, and resource utilization. The TE technology allows network administrators to optimize the utilization and performance of network resources by specifying paths and allocating bandwidth to manage network traffic. In a cross-region network, the TE technology is used in combination with CSPF to ensure that path selection conforms to the traffic engineering policies set by network administrators.

[0003] The cross-region CSPF network computing system that extends IGP may have some deficiencies in the current technology, mainly including the following aspects:

[0004] 1. Complexity and scalability: Cross-region CSPF systems usually need to handle path calculations and optimizations for large-scale networks, which may lead to an increase in system complexity. Managing and maintaining large-scale routing policies and constraint conditions may become difficult, especially when the network topology changes frequently or the network scale is huge.

[0005] 2. Computational overhead and performance: The CSPF algorithm needs to consider various constraint conditions, including bandwidth and delay, when calculating the optimal path, which may result in a large computational overhead. In a large network, frequent path calculations and updates may affect system performance, especially in application scenarios with high real-time requirements.

[0006] 3. Handling of dynamic network changes: There are dynamic network changes in cross-region networks, including link failures and topology changes. Traditional CSPF systems may not be able to respond to these changes in real time, resulting in problems such as unstable network paths or unbalanced resource utilization.

[0007] 4. Cross-domain coordination and consistency: Cross-region CSPF systems need to ensure consistent path selection coordination between different autonomous systems to avoid unnecessary routing oscillations or path preference problems. This involves cross-domain coordination and unified routing policy management, and may require complex protocols and mechanisms to ensure consistency.

[0008] Therefore, it is necessary to design a cross-region CSPF network computing system that extends IGP to solve the above problems. Summary of the Invention

[0009] The purpose of the present invention is to solve the deficiencies existing in the prior art, and to propose a cross-region CSPF network computing system that extends IGP.

[0010] To achieve the above object, the present invention adopts the following technical solutions:
