F5-BIG-LC-R4800 Link Controller

F5-BIG-LC-R4800 – For Larger Internet Traffic and Complex Routing Needs

F5-BIG-LC-R4800 is a high-performance model within the r4000 series, designed as an enhanced solution to meet more demanding Internet egress challenges. Compared to the main model F5-BIG-LC-R4600, it unlocks greater hardware potential through software licensing. Its core advantages include approximately 67% higher throughput capacity (50G vs 30G), 50% more new connection processing capacity (750K vs 500K CPS), and more business processing cores (16 vs 12 vCPUs). These improvements enable it to serve industries such as high-traffic e-commerce, online education, and SaaS services that demand exceptional Internet connection quality and reliability.

F5-BIG-LC-R4800 Features

50Gbps Link Aggregation Throughput
The LC-R4800 boosts total link management throughput to 50Gbps, easily handling and aggregating multiple 10-gigabit leased lines. It serves as a high-performance internet gateway for data centers, confidently meeting current and future bandwidth growth needs.

750K Connections per Second
Powered by stronger processing cores, it handles up to 750,000 new connection requests per second. In high-concurrency inbound scenarios like large promotions or live streaming, its robust intelligent DNS responds instantly to global user requests, quickly and accurately directing traffic to the optimal link.

Enterprise-Grade 16-Core Business Processing
With 16 dedicated vCPU cores for business processing, it delivers lower-latency decision-making when executing thousands of complex outbound routing policies based on application or user attributes — enabling enterprises to achieve precise, efficient bandwidth cost control.

Sub-Second Link Health Monitoring
Offers enterprise-grade link high availability. Through 24/7 sub-second monitoring, it ensures instant, seamless traffic switching to healthy links if an ISP link fails, keeping critical business connectivity uninterrupted.

Q1: Why choose the LC-R4800 instead of the LC-R4600?
A: The primary reason is its superior processing power and higher bandwidth management capacity. If your company’s total internet outbound bandwidth exceeds 30Gbps, or if you need to implement highly complex, application-based routing strategies, the F5-BIG-LC-R4800 offers a decisive advantage with its higher throughput and additional CPU cores.

Q2: Do the LC-R4800 and LTM-R4800 use the same hardware?
A: Yes, both models are built on the same r4800 hardware platform. The difference lies in software licensing: the F5-BIG-LC-R4800 activates the Link Controller (LC) functionality for managing internet links, while the LTM-R4800 activates the Local Traffic Manager (LTM) functionality for managing internal server traffic.

Q3: Can the LC-R4800 manage a 40Gbps internet link?
A: Yes. With a total throughput capacity of 50Gbps and support for 25G physical interfaces, the F5-BIG-LC-R4800 can easily handle a single 40Gbps link (with appropriate optical modules or connection via a switch), or aggregate multiple 10G/25G links with performance to spare.

How Does 50Gbps Link Aggregation Benefit Enterprise Networks?

• Significantly increases total bandwidth capacity
• Enhances network reliability and high availability
• Improves traffic scheduling and load balancing capabilities
• Supports complex applications and high-concurrency scenarios
• Provides scalability and flexibility for future upgrades and expansion

50Gbps link aggregation elevates enterprise networks to a new level in terms of bandwidth, reliability, flexibility, and performance.
