AI Technical Summary

Problems solved by technology

Considering the large number of LSPs in the network, complex configurations can cause rollout delays and additional costs
Also, manual configuration is error-prone since the thresholds for each LSP must be consistent across all nodes
Furthermore, it is difficult to maintain thresholds when they need to be updated based on changing network conditions
[0006] In summary, manually switching threshold provisioning is costly, error-prone, and has poor maintenance properties

Embodiment Construction

[0024] For purposes of illustration and not limitation, the following description is set forth in specific details, such as particular network topologies, including particular network nodes, in order to provide a thorough understanding of the present disclosure. It will be apparent to those skilled in the art that the present disclosure may be practiced in other embodiments that depart from these specific details. For example, skilled artisans will appreciate that the present disclosure may be employed in conjunction with the following Figure 1 to Figure 7 The specific Multiprotocol Label Switching (MPLS) discussed and the specific MPLS terminology below used to illustrate the present disclosure differ from implementations. Also, although the present disclosure is described in part with reference to a ring network, the present disclosure may be implemented in other networks to which mobile or stationary users may attach. For example, the present disclosure may be applicable ...

Abstract

The present disclosure relates generally to the field of label switching. More specifically, the present disclosure relates to techniques for providing, forwarding and distributing load balancing information in a label switched network. A method of providing load balancing information in a label switching network comprises the steps of: configuring (S402) load balancing information by a first router (40) of the label switching network, the load balancing information indicating conditions under which the load balancing performed by the class of data packets comprising one or more data packets; and providing (S404) the configured load in one message to at least one second router (20) of the label switching network by the first router (40) The balancing information is combined with label information associated with the class of data packets to establish at least a segment of a path for label switching one or more data packets of the class of data packets through the label switched network based on the label information.

Description

technical field [0001] The present disclosure relates generally to the field of label switching. More specifically, the present disclosure relates to techniques for providing, forwarding and distributing load balancing information in a label switched network. Background technique [0002] In the Mobile Backhaul (MBH) part of a communication network, the handover thresholds that trigger load balancing in nodes of the MBH part (eg microwave ring network) are manually configured along Label Switched Paths (LSPs). In a communications network, such as a telecommunications network, the backhaul portion of the network typically includes intermediate links between the core or backbone network and particularly small sub-networks at the edge of the overall network. [0003] For example, the bandwidth of a microwave link is not necessarily fixed all the time, but is prone to fluctuate due to external conditions such as weather. Typically, higher modulation schemes, which provide high...
