  JANUS is an abbreviation used in networking that refers to Joint Architecture for Network Unified Services , a concept or project to unify and simplify the management of complex network services. Depending on the organization or context, JANUS may differ in implementation and objectives but generally looks into improving flexibility, scalability, and efficiency in modern networks. Here are some key aspects that JANUS might encompass: ________________________________________ 1. Unified Network Architecture • Layer Integration: JANUS aims to integrate multiple layers of the network stack, such as data, control, and management planes, to make network operations much easier. • Multi-Domain: Provides an easy way to integrate coordination across multiple network domains, including on-premises, cloud, edge, and hybrid environments. ________________________________________ 2. Advanced Service Orchestration • End-to-End Service Delivery: Provides a holistic view of service deploymen...

  In June-2024 , Pakistan went through some major online hiccups because some important underwater wires got busted. The big ones that hit the skids were these two cables called SMW4 and AAE-1 . That SMW4 wire, which is super important for the world's internet, got messed up in June and fixing it was a big job. Then came August, and the AAE-1 started to give headaches too. All this trouble knocked down the internet strength by about 1.75 terabits per second. Yeah, that made using the net in Pakistan pretty slow, and it wasn't easy getting online. Traffic jams on the web got bad when everyone was online at the same time making it tough to get to stuff we need. The online stuff had to go down different digital roads, yet that didn't quite fix the whole problem. Getting everything back to normally took a bunch of months, and they didn't finish fixing the SMW4 until way later in 2024 . Plus, things like DDoS attacks and messing up the big internet service providers' ...

  Abstract:-   On July 19, 2024, a routine update to CrowdStrike's Falcon sensor software turned into a global disruption, highlighting the vulnerabilities of even the most advanced cybersecurity systems. The update contained a logic error which resulted in a system wide crash across industries such as aviation, health, and finance. This blog is based on lessons learned from this incident and stresses the need for strong test procedures, communication plans and contingency plans in information technology systems.      The Cascade of Disruptions The CrowdStrike service interruption exemplified the extent to which IT systems are deeply embedded in infrastructure. Airlines cancelled tens of thousands of flights due to the failure of operational systems leaving passengers at a standstill1. Banking services experienced interruptions, healthcare providers faced challenges in accessing critical data, and retail operations were hindered by system failures. This interco...
