However, not all ASNs are … Read more
The terms east-west traffic and north-south traffic are pivotal for understanding data flows. These concepts are not limited to data centers or enterprise networks; they also have significant implications in Internet Service Provider (ISP) networks. While ISPs primarily focus on external connectivity (north-south traffic), the importance of east-west traffic within their networks is growing as … Read more

/127’s for point-to-point links (RFC 6164) instead of /64’s https://datatracker.ietf.org/doc/html/rfc6164 [RFC4291] specifies that interface IDs for all unicast addresses, except those that start with the binary value 000, are required to be 64 bits long and to be constructed in Modified EUI-64 format. In addition, it defines the Subnet-Router anycast address, which is intended to … Read more
I was going through some older hard drives and came across some of these photos of Baicells, Cambium and other gear on towers. These were installed for Wireless Internet Service Providers (WISPs). See below for those who don’t know what a WISP is. A Wireless Internet Service Provider (WISP) is a telecommunications company that delivers … Read more

In this post, I will explore the significance of BGP and why it is often referred to as the backbone of the internet. I talk about BGP … Read more
In this blog post, I will compare XGS-PON (10 Gigabit Symmetrical Passive Optical Network) and GPON (Gigabit Passive Optical Network) to understand why XGS-PON is emerging as the superior choice for ultra-fast fiber internet. Many Wireless Internet Service Providers (WISPS) are considering getting into fiber to the home (FTTH). Understanding GPON Gigabit Passive Optical Network … Read more
