j2sw Least privilege is a security principle that aims to limit user access rights to the minimum necessary permissions required to perform their tasks. By granting only the essential permissions, you reduce the number of potential entry points for unauthorized access into the system. Additionally, In the unfortunate event of a security breach, attackers with limited … Read more
A key component enabling this efficiency is the optical splitter, which divides the optical signal to serve multiple endpoints. However, choosing the right GPON splitter strategy is crucial
When it comes to networking and the internet, two terms frequently come up: TCP (Transmission Control Protocol) and IP (Internet Protocol). These are fundamental protocols that enable communication between devices over the internet. However, they serve different purposes
A dedicated management network is the backbone for efficient monitoring, troubleshooting, and administration
When choosing an internet service provider (ISP), many consumers focus solely on the advertised speed, measured in megabits per second (Mbps) or gigabits per second (Gbps). While speed is undoubtedly important, it is far from the only factor that determines the quality of your internet experience. Here’s why raw speed is not everything when selecting … Read more
In a GPON (Gigabit Passive Optical Network), splitters are essential components that allow multiple end users to share a single fiber optic link from the service provider’s central office. Key Reasons for Using Splitters in GPON
In the broadband industry, the race for higher speeds has dominated marketing campaigns and consumer expectations. Internet Service Providers (ISPs) continually tout gigabit speeds as the ultimate benchmark for quality. While speed is important, a more critical yet often overlooked aspect of internet performance is interconnection—the way ISPs connect and exchange traffic with other networks. … Read more
The IP (Internet Protocol) packet header is a crucial part of how data is transmitted across networks. It contains vital information that helps routers and devices determine where the packet is coming from, where it’s going, and how to handle it. In this post, we’ll break down the structure of an IPv4 packet header, explain … Read more
The TCP/IP (Transmission Control Protocol/Internet Protocol) is the backbone of the internet and most modern networks. It ensures that data is transmitted reliably and efficiently between devices, whether you’re sending an email, streaming a video, or browsing a website. In this blog, we’ll break down how TCP/IP works, its layers, and how data moves across … Read more
In the world of internet networking, Autonomous System Numbers (ASNs) play a crucial role in routing data efficiently between different networks. ASNs are unique identifiers assigned to Autonomous Systems (AS)—large networks or groups of IP addresses that operate under a single organization, such as ISPs, cloud providers, or large enterprises. However, not all ASNs are … Read more
Unimus & Core 2.6.2 were released yesterday! This is a minor feature, performance and bugfix release: Download at https://unimus.net/download
High Availability in Ubiquiti. UniFi Shadow Mode is a high-availability (HA) feature for UniFi Cloud Gateways (UDM-Pro, UDM-SE, UDM-Pro-Max, EFG) that provides instant failover by creating an active-passive pair. A secondary “Shadow” gateway mirrors the primary’s configuration and state, automatically taking over within seconds if the primary fails, using Virtual Router Redundancy Protocol (VRRP) and shared IP/state … Read more
