1.0 BCM55030B2KFBG Datasheet: Inside the StrataXGS Architecture
In the architecture of modern enterprise networks, the BCM55030B2KFBG stands as a legendary workhorse. Part of the Broadcom StrataXGS® family, this highly integrated switch-on-a-chip (SoC) is designed to handle the rigorous demands of high-density 10GbE environments. As of 2026, data center traffic has increased by an estimated 300% since 2022, making the efficiency of switch silicon like the BCM55030 more critical than ever.
The BCM55030B2KFBG isn't just a basic router component; it’s a sophisticated engine capable of line-rate switching and advanced L2/L3 routing. For engineers building the next generation of top-of-rack (ToR) switches, this chip offers a unique value proposition: massive bandwidth combined with a manageable power profile.

1.1 Advanced Packet Buffer and Throughput Capabilities
One of the primary pain points in high-traffic networks is packet loss during micro-bursts. The BCM55030B2KFBG addresses this with an integrated, high-performance packet buffer. By utilizing intelligent buffer management, it ensures that high-priority voice and video traffic maintain low jitter even when the network is congested.
2.0 Key Features of BCM55030B2KFBG: More Than Just Speed
Beyond raw 10GbE ports, the BCM55030B2KFBG integrates several "smart" features that define modern networking. This includes Broadcom’s signature ContentAware™ technology, which allows for deep packet inspection (DPI) at line rate.
2.1 ContentAware™ Processing for Secure Networking
In 2026, security is no longer an "add-on"—it must be baked into the silicon. The ContentAware engine in the BCM55030 enables hardware-based ACLs (Access Control Lists) and traffic policing. This allows the switch to identify and block malicious traffic patterns before they even reach the host CPU.

3.0 BCM55030 vs StrataDNX: Choosing the Right Switch Silicon
When selecting a Broadcom part, engineers often debate between the StrataXGS (like the BCM55030) and the StrataDNX series. While StrataDNX is built for massive carrier-grade scalability, the BCM55030B2KFBG is the optimized choice for enterprise campus and mid-range data center applications.
3.1 Efficiency Benchmarks for Mid-Tier Data Centers
The BCM55030 offers a significantly lower thermal design power (TDP) compared to its carrier-grade cousins. In fan-cooled server racks, this translates to lower energy costs and higher reliability.
