JUNIPER TROUBLESHOOTING TRICKS
🧰 JUNIPER TROUBLESHOOTING TRICKS In day to day network operations, some of the most disruptive incidents come from very small components. A link drops because an optic stops responding, an interface refuses to come back, or a transceiver behaves inconsistently. Traditionally, this often ends with a request for a field engineer to reseat the module. […]
SPEED VS STABILITY IN NETWORK OPERATIONS. A FALSE TRADE OFF?
SPEED VS STABILITY IN NETWORK OPERATIONS. A FALSE TRADE OFF? In network operations, time pressure is constant. There are always pending tasks, business requests, customer activations, upgrades, and unexpected issues. At the same time, every change introduced into a live environment carries inherent risk. This creates a familiar dilemma for operational teams. Should speed or […]
THE BIGGEST MISCONCEPTION ABOUT 24/7 NOC SERVICES
THE BIGGEST MISCONCEPTION ABOUT 24/7 NOC SERVICES Downtime is not just a technical problem. It is a financial one. According to widely cited industry research, the cost of IT downtime can reach thousands of dollars per minute depending on the business model and sector. Even short lived incidents can quickly translate into revenue loss, customer […]
WHEN NETWORK RECONVERGENCE LOOKS LIKE FAILURE TO MONITORING
WHEN NETWORK RECONVERGENCE LOOKS LIKE FAILURE TO MONITORING Many networks reconverge exactly the way they are designed to. A link drops, traffic shifts, paths update, and services continue to run. But the monitoring system does not understand that behavior. It sees a short change in state and sends an outage alert anyway. The result is […]
A PRACTICAL PATH TO OUTSOURCING WITHOUT UNNECESSARY RISK
A PRACTICAL PATH TO OUTSOURCING WITHOUT UNNECESSARY RISK For many organizations, outsourcing is no longer viewed as an all or nothing decision. Instead of transferring large operational responsibilities in a single step, teams increasingly prefer a gradual and controlled approach. This shift is driven by a simple concern. Large transitions introduce uncertainty, while smaller changes […]
ROUTING POLICIES ARE NO LONGER ROUTE MAPS
ROUTING POLICIES ARE NO LONGER ROUTE MAPS For a long time, routing policy design across many platforms revolved around a single concept. The route map. It worked, but it was rigid, static, and hard to scale. As networks grew and requirements became more complex, this model quickly showed its limits. Modern service provider and data […]
OBSERVABILITY, TELEMETRY, AND THE REALITY OF gNMI IN MULTI-VENDOR ENVIRONMENTS
OBSERVABILITY, TELEMETRY, AND THE REALITY OF gNMI IN MULTI-VENDOR ENVIRONMENTS While many networks are in freeze mode and changes are on hold, there is finally some space for experimentation, learning, and simply playing around with topics we normally postpone. This time at ITcare we decided to spend it diving deeper into observability using telemetry, and […]
MONITORING IS A CORRELATION PROBLEM, NOT A DASHBOARD PROBLEM
MONITORING IS A CORRELATION PROBLEM, NOT A DASHBOARD PROBLEM Many teams today run five or six monitoring tools at the same time. They use LibreNMS for one part, Nagios for another, Icinga for alerts, PRTG or SolarWinds for graphs, and then a few custom scripts on the side. Each tool does what it is supposed […]
THE OPEN SOURCE DIVIDE: WHY NETWORK ENGINEERS ARE STILL FIGHTING YESTERDAY’S BATTLES
THE OPEN SOURCE DIVIDE: WHY NETWORK ENGINEERS ARE STILL FIGHTING YESTERDAY’S BATTLES Here’s an uncomfortable truth: while software developers enjoy a thriving open source ecosystem, network engineers are stuck running production networks on abandoned tools with unpatched vulnerabilities. RANCID has CVEs from 2008 that remain unfixed. TACACSGUI only supports Ubuntu 18.04 (end-of-life 2023) with […]
WHY STANDARDS AND CONSISTENT DESIGN MATTER MORE THAN YOU THINK
WHY STANDARDS AND CONSISTENT DESIGN MATTER MORE THAN YOU THINK Why Standards and Consistent Design Matter More Than You Think Almost every company that reaches out to us does so because something in their network is not working the way it should. After many projects, one pattern became obvious. The root cause is rarely […]
