Media Relay Point for IP Recording Network Services
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional passive tap IP recording techniques require the deployment of recorders along communication routes, which can lead to inefficiencies and incompatibilities with certain communication devices, particularly those that do not support recording as a network service.
Innovation Solution
Implementing a media relay point between network devices to provide recording as a network service, allowing IP packets to be directed to a recording device, and enabling advanced services like codec changes and encryption, thereby supporting legacy or third-party devices that may not natively support recording.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If recorders are deployed along communication routes using passive tap IP recording technique, then recording capability is provided, but device complexity and incompatibility with certain communication devices increase
Solution Approach 1:
The patent introduces a media relay point as an intermediary component between network devices. This relay point intercepts IP packets associated with communications, performs recording operations, and forwards packets without requiring modification to existing communication devices. The relay point acts as a mediator that provides recording functionality while maintaining compatibility with legacy devices that do not natively support recording services.
2Reliability
If recorders are deployed along communication routes, then recording of communications is achieved, but ease of operation and compatibility with legacy devices decrease
Solution Approach 1:
The media relay point is designed as a universal component that can handle multiple network protocols and communication types (voice, video, data). It provides recording functionality for various communication devices including legacy devices that do not support recording natively. The relay point universally intercepts and processes IP packets regardless of the specific communication device type, thereby improving ease of operation and broadening recording coverage.
3Reliability
If recording devices are inserted into the call path, then recording functionality is provided, but packet loss may occur and system complexity increases
Solution Approach 1:
The media relay point creates a copy of IP packets associated with communications for recording purposes. The original packets continue to flow through the network to their destination without interruption, while duplicate packets are directed to recording devices. This copying mechanism ensures that recording functionality is provided without causing packet loss in the primary communication path, as the original packets are not blocked or dropped.

AI summary
IP packets associated with a communication are received at a first network device in an IP recording system. The first network device communicates to other devices in the IP recording network to receive a determination if the IP packets associated with the communication are to be recorded. The first network device may then be instructed to direct the IP packets associated with the communication to a recording device. In some implementations, the IP packets may duplicated, encrypted, re-encoded, compressed, etc. prior to recording.
