Network Device Signaling Interception for VoIP QoS
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for providing guaranteed levels of service in delay-sensitive communication networks, such as VoIP, are computationally intensive and lack adaptability due to reliance on heuristic predictions that may not accurately reflect future data traffic patterns.
Innovation Solution
A network device with input and output interfaces and a processor that intercepts signaling datagrams, forwards them to a SIP server, and applies quality-of-service (QoS) to bearer data, allowing for real-time monitoring and adaptation of network resources to ensure optimal delay-sensitive communication sessions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If heuristic prediction is used to monitor data traffic and make future resource allocation decisions, then service providers can attempt to provide guaranteed levels of service, but the process becomes computationally intensive and lacks adaptability because the data used has already passed through the router
Solution Approach 1:
The patent applies preliminary action by intercepting signaling datagrams (such as SIP messages) before actual data traffic flows through the router. By analyzing signaling data that contains future traffic pattern information, the system proactively allocates network resources in advance, avoiding the need for computationally intensive real-time analysis of actual traffic data after it has already passed through the network device.
Solution Approach 2:
The patent uses signaling datagrams as an intermediary to obtain information about future data traffic patterns. Instead of directly monitoring and analyzing actual data traffic (which is computationally intensive and retrospective), the system intercepts signaling messages that carry information about upcoming communications, using these as a proxy to make proactive resource allocation decisions.
2Reliability
If heuristic prediction monitors actual data traffic in real-time, then service providers can observe customer traffic patterns, but the method lacks accuracy because subsequent data may not be of the same type or pattern as data that has already traversed the router
Solution Approach 1:
The system performs preliminary analysis of signaling datagrams that indicate future communication patterns before the actual data traffic occurs. This allows the network device to adapt resource allocation to match the actual traffic that will flow, rather than relying on retrospective analysis of past traffic that may not represent future patterns.
Solution Approach 2:
The patent implements feedback by using signaling datagrams to provide advance information about upcoming traffic patterns. This feedback mechanism allows the system to adjust resource allocation proactively based on reliable information from signaling messages, creating a closed-loop system that adapts to actual traffic demands as they are announced through signaling protocols.
Data Source
AI summary
A communication session over a network is facilitated. A signaling datagram from a source device having a source identity may be intercepted by a network device, and a response datagram may be generated for instructing the source device to send a subsequent datagram to the network device. The signaling datagram may be forwarded to a SIP server, where the SIP server associates the source identity with the network device acting on behalf of the source device, and where the SIP server operates to connect a destination device with the source device to establish a communication session over the network. The subsequent datagram may be received from the source device, and the subsequent datagram may be made available to the destination device via the network.
