In examples, when a customer orders communication services from the network services provider (or associates the communication services with a third-party Internet telephony service), the network services provider provides the customer a unique identifier that is provisioned into that customer's instance of the third-party Internet telephony service. When the customer makes a call using the third-party Internet telephony service, the identifier is inserted into the communication (e.g., in a SIP header). The identifier is extracted when the communication is received at the network services provider and used to identify the customer so that appropriate services, service levels, etc. can be applied to the call.

A multi-path parallel byzantine fault tolerance consensus method based on a multi-committee mechanism

PendingCN122247590ACompress the communication scale within the groupReduce consensus latencySecuring communicationByzantine fault toleranceLeader election
This invention proposes a multi-committee parallel Byzantine fault-tolerant consensus method, GP-BFT. This method groups system replicas into multiple independent committees based on the minimum Byzantine fault tolerance parameter. Each committee executes consensus in parallel, effectively reducing intra-group communication. A two-level leader election is employed: each committee elects a first-level leader responsible for intra-group consensus, and a second-level leader is elected from among the first-level leaders using a threshold coin to coordinate globally. A dual timeout handling mechanism is designed: when less than half of the committees time out, cross-path collaborative commit is used, leveraging committees that have completed consensus to drive the timed-out committees to quickly resubmit; when more than half of the committees time out, aggregated timeout certificates are used to advance the global round. This method significantly reduces consensus latency and communication overhead in large-scale replica scenarios while ensuring security and liveness.
