The answer to that question depends on today's definition of a self-healing network and what technologies are available to facilitate the self-healing process. Let's learn what a self-healing network is now, how it works and the benefits that can be gained.
Traditional enterprise networks were originally architected to fail over automatically to standby hardware and associated backup links when physical or logical failures occurred. However, the techniques used for this type of redundancy were relatively rudimentary and had no visibility into the type of traffic flows that were affected.
By today's standards, self-healing networks go far beyond simple network redundancy. These networks rely on automation, machine learning (ML) and AI to prevent catastrophic network connectivity failures from completely halting traffic. Self-healing networks also aim to optimize, predict and automatically intervene when network service degradation is detected or even anticipated.
For organizations interested in exploring what self-healing networks can realistically deliver today to solve network problems, perhaps the best place to start is to look at how network health and performance data can be collected and analyzed.
AI for IT operations (AIOps) platforms are a great segue into full self-healing network operations as they deliver automated data collection, root cause analysis and remediation suggestions. The suggestions produced by the AIOps platform can then be acted upon by IT staff. This gets staff accustomed to AI-based decisions and what level of trust can and should be granted.
The final piece to the self-healing network puzzle is to enable the network to make configuration changes on the network team's behalf that work to prevent faults and optimize data transport flows. It takes time for network teams to trust self-healing intelligence to make critical network modifications on their behalf. But, once that trust is earned, the true power of self-healing networks can finally be realized.
Self-healing networks are networks with built-in properties to protect against failures by predicting problems, providing remediation or workarounds, supporting recovery and preventing future incidents. Network failures can range from complete loss of connectivity to smaller quality issues that can nonetheless have a big impact on business applications and outcomes.
Today, we have the computing power and AI algorithms advanced enough to enable prediction and transform network operations in ways unimaginable a few decades ago. We can anticipate and correct against failures before they happen and know with confidence what the results of new configurations will be.
Another good example is in healthcare emergency services like 9-1-1, where the network must be reliable and always stay online. In these use cases, self-healing networks can deliver essential reliability for business-critical applications.
This process often relies on network redundancy features that kick in when a failure is detected, or through the use of artificial intelligence and machine learning algorithms that identify, diagnose, and resolve network anomalies.
The foundations of a self-healing network are rooted in cutting-edge technologies such as AIOps and autonomous network principles. These technologies enable the network to autonomously monitor, analyze, and react to network conditions in real-time.
AIOps, a blend of AI for network operations, plays a critical role by providing the intelligence and learning capabilities necessary for proactive problem-solving. Furthermore, the integration of autonomous features ensures that these networks can independently manage routine tasks and anomalies, reducing the need for human intervention and enhancing overall network resilience.
Self-healing networks strive to reduce the operational burden on IT staff, allowing them to focus on more strategic tasks rather than routine network management. Another key objective is to improve network security through continuous monitoring and rapid response to potential threats.
A self-healing network begins its process with continuous monitoring. Utilizing AI networking, the system constantly scans for network performance indicators, traffic patterns, and potential security threats. This real-time surveillance is crucial for the early detection of issues, allowing the network to proactively address them before they escalate into significant problems.
At this stage, the network leverages advanced machine-learning algorithms to identify anomalies and predict potential issues. By comparing current data against historical trends and known issue signatures, the network can swiftly pinpoint irregularities. This predictive insight is a cornerstone of the self-healing mechanism, enabling preemptive action.
Upon detecting an anomaly, the network shifts into a mode of autonomous decision-making, characteristic of a self-driving network. Here, pre-defined policies and learned experiences guide the network in choosing the best course of action, such as rerouting traffic, adjusting bandwidth, or isolating compromised segments, all without human intervention.
Finally, the network implements the chosen corrective measures. In addition to resolving the immediate issue, the network also learns from the incident. This continuous learning loop allows the network to optimize its responses over time, improving efficiency and reducing the likelihood of similar issues reoccurring.
The foremost advantage of a self-healing network is its exceptional reliability and consistent uptime. By proactively identifying and resolving issues, these networks virtually eliminate unexpected downtime. This reliability is essential for maintaining business continuity, ensuring that critical network-dependent operations are always running smoothly.
Self-healing networks significantly alleviate the workload on IT staff. Automated monitoring and problem-solving free up IT teams from routine network management tasks, allowing them to concentrate on strategic projects and innovation. This shift not only improves team efficiency but also enhances job satisfaction by focusing on more engaging and impactful work.
A key feature of self-healing networks is their self-learning capability, which allows for ongoing optimization. The network learns from each incident, adapting its responses to be more effective over time. This adaptability ensures that the network remains efficient and responsive to new challenges and changing organizational needs.
Ensuring that self-healing capabilities seamlessly work with existing network infrastructure is a major challenge. Diverse IT environments with a mix of old and new technologies can complicate the deployment of self-healing networks. This necessitates a tailored approach to network design and configuration, often requiring specialized expertise and additional investments.
Self-healing networks rely heavily on AI and machine learning models, which need regular maintenance and updates to remain effective. Keeping these models up-to-date requires continuous data analysis, algorithm adjustments, and testing. This ongoing requirement for specialized skills and resources can be a challenge for many organizations.

Network self-healing is when network problems are resolved without the need for humans to get involved. A network automation tool can detect and remediate outages, failures, and breaches of all kinds.
Automation can simplify your life, but is it worth the investment? While many IT professionals have the skills to create their own scripts or configure open source tools, not all have the time. The productivity gains alone are enough for many organizations to invest in network automation tools.
In fact, disruptions of all kinds could become more prevalent and more problematic as the world becomes more dependent on the very digital networks powered by telcos and communication service providers, or CSPs.
As workers and consumers shifted their labor, recreation, communications and shopping patterns to routines that still persist, the resulting stress on telecommunications network was profound. Overnight, usage exploded in many places, as more and more people tried to squeeze into the same amount of network capacity (at least until the networks could respond by scaling up capacity rapidly).
This was an unprecedented and dramatic situation that exposed some hard truths about telecom network maintenance, namely that the current fragmented system is not positioned well to confront such an existential threat. A slowly buffering movie is one thing. A dropped sales pitch or remote wedding ceremony is another problem entirely.
