Ensuring Uninterrupted Wi-Fi Roaming Connectivity-Asterfusion’s Anycast Gateway

In today’s fast-paced office environments, Wi-Fi roaming has become essential. Employees are constantly on the move, switching between their desks, meeting rooms, and even different floors, all while staying connected on their phones and laptops. But traditional Wi-Fi roaming technology often struggles to keep up with this level of mobility. The issue? As employees move, their devices change IP addresses, forcing the TCP/IP connection to be re-established—and that leads to frustrating disconnections. So, is there a solution that can allow employees to roam freely across the network without losing connectivity? Let’s dive into it and find out!

Traditional Wi-Fi Roaming Challenges

While traditional Wi-Fi roaming aims to facilitate user mobility, it often presents a series of challenges that can adversely affect user experience. In conventional systems, when a user moves from one access point (AP) to another, the traffic typically has to take a detour back to the original AP. This process involves creating a tunnel between the original host node and the new roaming node. The need for a connection back to the Access Controller (AC) adds layers of latency and complexity, mirroring roaming mechanisms found in 5G networks.

Latency and complexity are the enemies of a smooth user experience. Every time a detour is made, there’s a risk of delay, which can be particularly detrimental during critical business operations or educational sessions. The consequences can range from minor inconveniences, such as a momentary lapse in communication, to major setbacks, such as lost opportunities or critical miscommunications that could jeopardize a project.

Asterfusion’s Solution: Anycast Gateway Technology

Recognizing these challenges, Asterfusion has innovated a groundbreaking solution: Anycast Gateway technology. This approach addresses the detour problem associated with traditional roaming, allowing for a more direct traffic flow while simplifying overall network management.

Here’s how Asterfusion enhances the Wi-Fi roaming experience:

Simplified Traffic Flow: In this revolutionary model, the AP’s primary responsibility is to forward traffic directly to the upstream leaf switch without local switching. By eliminating the need for traffic to detour back to the original AP, Asterfusion ensures that data is routed efficiently and promptly.

Anycast Gateway Configuration: Each leaf switch is equipped with an Anycast Gateway, which plays a pivotal role in ensuring that roaming clients maintain the same IP address, regardless of their movement across different switches. This eliminates the cumbersome need for clients to reconnect or re-authenticate every time they transition within the network.

Seamless Roaming with BGP-EVPN: The implementation of the BGP-EVPN protocol allows leaf switches to share local ARP table information with all spine switches. This capability facilitates the smooth routing of roaming traffic, ensuring that the client’s home leaf switch manages authentication and retains essential client information. As the client moves to a new switch, this data is synchronized with the remote leaf switch, allowing for an uninterrupted user experience.

Ultra-Fast 10-Millisecond Handover

For our existing clients, Wi-Fi roaming represents a critical focus area during network upgrades. Imagine navigating through a large office space—say, a sprawling 2,000 square meter environment—where users can freely roam from one end of the building to the other while maintaining consistent connectivity across multiple access points (APs). The handover time between APs is approximately 10 milliseconds, ensuring that users experience minimal disruption during their transitions.

What’s more remarkable is that this ultra-fast 10-millisecond handover time is maintained even when users traverse across leaf switches. This capability guarantees seamless, high-speed roaming throughout the entire network, allowing users to move between different segments without any noticeable interruption. This level of performance is not merely a technical achievement; it is essential for maintaining a consistently reliable and enjoyable user experience.

The Future of Connectivity

As we continue to advance into an increasingly interconnected world, the need for robust and efficient Wi-Fi solutions will only grow. Asterfusion’s Anycast Gateway technology positions itself at the forefront of this evolution, addressing the critical needs of modern users who demand uninterrupted connectivity, whether they are in a corporate office, a university campus, or even their own homes.

In conclusion, Wi-Fi roaming is not just about mobility; it’s about ensuring that our digital experiences remain fluid and efficient. The innovations brought forward by Asterfusion exemplify how technology can solve real-world problems, enhancing our ability to communicate, collaborate, and connect in meaningful ways. As we navigate this digital landscape, let us embrace these advancements that promise to redefine our interactions and experiences in an ever-evolving world. With seamless connectivity, we can focus on what truly matters: the work we do and the relationships we build.
