Cloud Scale Networking

Best-in-class infrastructure built on Broadcom networking solutions.
Network operators are facing workloads that are changing in unpredictable ways. Users are demanding massive increases in data volume while expecting to pay lower prices. These forces can choke networks, straining service-level agreements (SLA) and lowering asset utilization. Networks are also prone to inefficiencies in scaling, which unnecessarily increase capex and opex.
To help operators face these challenges, Broadcom offers a range of solutions starting with the new StrataXGS® Tomahawk™ single-chip switch, providing up to 3.2 Tb/s of bandwidth with 128 x 25G ports that can be combined into 32 x 100G ports. In conjunction with the market-leading StrataXGS® Trident II single-chip Top-of-Rack switches, the Tomahawk™ family offers OEMs, data center operators and service providers the ability to provide a vast array of configurations and deployment of best-fit physical networking elements in a fast, fat and flat connection topology.
Network operators can also evaluate cloud-scale blueprints for efficient network design with Broadcom's Cloud Scale Network Configurator. Activating the right services and features of the physical network elements can enable high performance and scale for all workloads, even in the face of unpredictability. And, the ability to integrate software-defined networking (SDN) and network function virtualization (NFV) services on top of the infrastructure allows operators to dynamically provision their networks for rapid deployment and innovation velocity. In a nutshell, this is what Cloud Scale Networking is all about.


Helping network operators evaluate the tradeoffs required when building the optimal cloud architecture for their workload needs.The Configurator leverages leading-edge networking solutions such as the StrataXGS® Tomahawk — and can provide valuable insights for planning next-generation networks.

25/50/100 GBE
The unprecedented bandwidth, port radix and endpoint scale of the StrataXGS® Tomahawk™ Series enables data center operators to achieve disruptive cloud-scale economics through the deployment of capex- and opex-efficient server/storage networking fabrics using cutting-edge 25G, 50G and 100G Ethernet. Broadcom is the first to deliver high-density 25G and 50G switching based on the specification it authored and co-founded as part of the 25G Ethernet Consortium.
The TruFlow™ flow processing engine is integrated into the NetXtreme® C-Series Ethernet controllers. These advanced Ethernet controllers are optimized for next-generation cloud data centers. TruFlow™ implements the fundamental SDN protocol constructs of classification/match/action processing in hardware, including the latest OpenFlow standard. It distributes flow processing into the server endpoints, allowing data center growth without impacting network and application performance. And TruFlow™ provides accelerated vSwitch data plane processing, increasing application performance up to 50 percent.
The FleXGS™ flow processing engine supports flexibly partitioned forwarding/match/action database scaling to enable 12x higher flow capacity vs. prior-generation products for dense, multi-protocol forwarding, lookup key extraction and packet classification. Operators can choose to deploy native FleXGS™ forwarding constructs in the Broadcom switch SDK or map to OpenFlow 1.3+ using Broadcom OpenFlow Data Plane Abstraction (OF-DPA) 2.0 software.
Integrated BroadView™ network instrumentation provides opex-critical network analytics for rapid operator response, including leaf-spine load balancing state, link utilization and health, application flow statistics, network congestion detection, and internal packet probing for flow diagnosis/debug. BroadView™ includes full ecosystem support for switching platforms via northbound SDK APIs to cloud-operating systems, SDN controllers and other third-party agents/applications — giving rise to powerful new network monitoring tools or enhanced capabilities of existing ones.
The StrataXGS® Tomahawk™ and StrataXGS® Trident II series feature SmartSwitch™ technologies designed to break through traditional silicon and system-imposed performance barriers in cloud-scale networking. Increased performance needs for server-to-server and server-to-storage communication are driving the need for fast, fat and flat networks. Dynamic workload placement and the need for granular traffic visibility, load balancing and diagnostics are similarly driving more flexible software defined networks (SDN). The SmartSwitch™ technologies include:
Enables cloud-scale network infrastructure virtualization using advanced Layer 2 over Layer 3 (L2oL3) network virtualization technologies such as VxLAN and NVGRE, delivering up to 4X greater scale
Delivers up to 5X higher packet buffer utilization and burst absorption performance using innovative traffic load-based intelligent and dynamic allocation schemes
Delivers highest Layer 2 and Layer 3 forwarding scale with network topology-based profiling for maximum deployment flexibility
Eliminates polarization and load imbalances in fat-tree networks possessing heavy and diverse traffic patterns
