The F5 BIG-IP Link Controller LC-R5800 is well-suited for organizations operating multiple data centers, relying on multiple ISP links for online services, or seeking to optimize WAN investments.
Compared to the previous-generation LC-R5600 series, the R5800 represents a major leap forward in link control performance. Its core advantages stem from a modern hardware architecture and a generational upgrade in network interfaces. It delivers multiple times the throughput and replaces legacy 10G/40G ports with 25G/100G interfaces – preparing your network for today’s and tomorrow’s bandwidth needs.
F5-Big-LC-R5800 Features
Maximize Link Performance
The R5800’s powerful processing capabilities allow you to aggregate links from different ISPs – whether fiber-optic or leased line. It not only aggregates total bandwidth but also routes traffic intelligently: reserving premium, high-cost links for latency-sensitive apps like video conferencing or VoIP, while assigning general web or download traffic to more cost-effective connections—ensuring every bit of bandwidth is used optimally.
Seamless Failover & Business Continuity
The Link Controller R5800 continuously probes each link’s latency, packet loss, and availability at sub-second intervals. Upon detecting degradation or outage, it automatically reroutes all traffic – including active sessions – to healthy links without disruption.
Superior End-User Experience
For inbound traffic, the Link Controller functions as an intelligent DNS server. When global users try to access your services, it returns the IP of the fastest ISP link based on their geographic location and real-time network conditions. This automatically routes users via the optimal path to your data center, slashing latency and boosting satisfaction.
Future-Ready Connectivity
The R5800 comes standard with high-speed 25G and 100G ports, ensuring your infrastructure keeps pace with evolving ISP bandwidth upgrades. Whether you’re currently on 10G or planning to move to 40G or 100G, the R5800 provides native support – eliminating the need for future hardware replacement and protecting your long-term investment.

Q: What types of businesses benefit most from the F5 Link Controller R5800?
There are three main categories:
- Enterprises where uptime and internet availability are mission-critical.
- Organizations with multiple ISP links looking to centrally manage and optimize performance across them.
- Companies undergoing digital transformation with rapidly growing outbound bandwidth demands.
Q: Can the LC effectively manage ISP links with unequal bandwidths (e.g., one 10G and one 2G)?
Absolutely. One of the core advantages of the Link Controller is its ability to handle asymmetric links. You can configure traffic distribution policies based on weight, ratio, or session count to ensure the higher-bandwidth link carries more load.
Q: How long does failover take if one ISP link goes down?
Thanks to the R5800’s powerful hardware and the Link Controller’s sub-second health monitoring, typical failover happens within 3 to 5 seconds. The transition is seamless and completely transparent to end users, with ongoing downloads or sessions automatically rerouted to a healthy link.
Q: Can we prioritize certain applications (like Office 365) to go through a specific ISP?
Yes. The LC-R5800 supports policy-based routing by application or IP address. For example, you can set a rule to prioritize all traffic to Office 365 servers through ISP A, ensuring optimal performance for critical applications.
Q: Is deploying and configuring the LC-R5800 complicated?
Not at all. F5 provides a user-friendly graphical interface and setup wizards to make basic link load balancing intuitive.
