F5-BIG-LC-R2800 Link Controller

F5-BIG-LC-R2800 – Optimized Internet Edge Performance for Growing Businesses

F5-BIG-LC-R2800 is an enhanced link load balancing solution designed specifically for small and medium enterprises with higher Internet egress traffic and more complex routing policies. Compared to the base model F5-BIG-LC-R2600, it delivers double the key processing capacity, supporting twice the new connection processing rate (350K CPS) and double the business processing cores (8 vCPUs). These advantages enable the LC-R2800 to serve enterprises with faster, smarter, and more reliable Internet connectivity.

F5-BIG-LC-R2800 Features

25Gbps Link Aggregation Throughput
The LC-R2800 raises total managed link throughput to 25Gbps, allowing smooth aggregation of multiple gigabit-level ISP links. It provides a high-speed, unified Internet gateway for your office or data center, confidently meeting rising bandwidth demands.

350K Connections per Second
The LC-R2800 processes up to 350,000 new connections/second – double the R2600’s capacity. As an intelligent DNS server for high concurrent inbound traffic, it quickly resolves and returns optimal access paths to global users, slashing access latency.

Enhanced Multi-core CPU Processing
Equipped with 8 vCPUs for business processing, the LC has more CPU resources to efficiently execute complex outbound routing strategies. Whether routing by cost, latency, or application type, it decides quickly to ensure optimal bandwidth allocation.

Link Health Monitoring at Second-level Granularity
It probes all links 24/7 at second-level intervals. On primary link jitter or failure, traffic switches instantly and seamlessly to healthy backups—automatically ensuring uninterrupted access for critical services like video conferencing and VoIP.

F5-BIG-LC-R2800 Datasheet

• L4/L7 Throughput: 25 Gbps / 17 Gbps
• Max L4 Concurrent Connections: 19M
• L4 Connections Per Second: 350,000
• Memory: 32 GB DDR4

Does the LC-R2800 have hardware compression like the LTM-R2800?
No. Compression is a feature exclusive to the LTM module, used to optimize application data. The LC (Link Controller) module’s core function is routing and ensuring link availability, so it does not include compression. The F5-BIG-LC-R2800 focuses solely on link load balancing.

Can the LC-R2800 manage 10G Internet leased lines?
A: Absolutely. The F5-BIG-LC-R2800 has a total throughput capacity of 25Gbps and physical ports supporting 10G/25G speeds. It easily manages one or multiple 10G Internet links, leaving ample headroom for traffic bursts and future bandwidth upgrades.

LC-R2800 vs LC-R2600 in Link Throughput and Connection Handling
F5-BIG-LC-R2800 offers the following specific improvements in link throughput and connection processing compared to F5-BIG-LC-R2600

LC-R2800 vs R2600 – Quick Wins

• 25 Gbps pipe: 25 % more bandwidth, more links, zero choke.
• 350 K CPS: 2× new connections per second – DNS answers fly.
• 8 vCPUs: double the brains for smarter, cheaper routing.

Overall, the LC-R2800 achieves a significant leap in both network bandwidth throughput and connection processing capabilities, which is suitable for more complex Internet egress environments and business scenarios.
