AI Technical Summary

Benefits of technology

The present invention provides a method for managing services in a virtual private networking environment where multiple networks share resources. It allows users to choose their own service labels when there're fewer connections than what was actually needed. Additionally, the invention ensures that all servers have access to this service label information even if some servers fail during communication. Overall, these technical features improve efficiency and reliability in providing service labels across various types of networks.

Problems solved by technology

The technical problem addressed in this patent is the difficulty in assigning service labels to specific virtual connections when managing a large number of VPNs. Existing solutions involve manually searching for relevant service labels and then adding them to the appropriate portions of the VPNs. However, manual assignment requires significant effort and slows down the process. Therefore, the patent proposes a solution called Active Layer Group Management (ALM), where the service label is automatically determined and distributed across the entire network.

Embodiment Construction

[0032]The following detailed description sets forth numerous specific details to provide a thorough understanding of the invention. However, those skilled in the art will appreciate that the invention may be practiced without these specific details. In other instances, well-known methods, procedures, components, protocols, algorithms, and circuits have not been described in detail so as not to obscure the invention.

[0033]A method and apparatus for adaptive service label management enables different types of service labels to be used depending on the particular properties of the VRF with which they are associated and the type of service to be provided on the network. A notion of service label type is introduced that allows service labels to be assigned in an adaptive manner depending to optimize scalability of the data plane, minimize overhead associated with service label management, and allow new services to be offered. Service label management may be done in a dynamic manner so that

Abstract

Multiple service label types may be used in a given network element to optimize scalability of the data plane, minimize overhead associated with service label management, and allow new services to be offered. Service label management may be done in a dynamic manner so that service labels may be selected for routes in a dynamic fashion as the network changes. VPNs handled by the network element may have different types of service labels, and different routes within a particular VPN may be allocated different service label types. Service label requests may be stored on the data plane to allow a service label request database to be restored from the data plane upon a control plane failure, so that new service labels are not required to be allocated after a control plane failure.
