As cloud computing continues to expand at an unprecedented pace, surpassing even the rapid advancements predicted by Moore’s Law, the demand for scalable infrastructure is skyrocketing. Some estimates suggest annual growth rates as high as 30 times, while others project even more dramatic increases—up to 100 times. To keep up with this explosive growth, cloud data centers are rapidly scaling up, with hundreds or even thousands of servers becoming a standard configuration in the market.
At this scale, the network faces significant challenges. The need for additional switches drives up capital expenses and increases management complexity. To mitigate these rising costs, network disaggregation has emerged as a popular solution. By decoupling switch hardware from the software it runs, businesses can avoid vendor lock-in and opt for in-house or third-party software, reducing costs substantially. However, while this approach addresses immediate financial concerns, it doesn’t fully resolve the ongoing operational expenses tied to managing large numbers of switches.
While network disaggregation offers savings in capital expenditures, it leaves operational costs largely unchanged. The number of switches remains the same, and addressing this complexity is essential to reducing long-term expenses. This brings us to the next phase of innovation: disaggregating ports from the switches that manage them.
Port Extension TechnologyToday, nearly every application we interact with—whether at home or in the workplace—is somehow connected to the cloud. From email services and mobile apps to corporate websites and virtual desktops, everything runs on cloud-based servers. For cloud service providers, this exponential growth presents both immense opportunities and daunting challenges. As demand surges, data centers must expand not only in terms of computing and storage capacity but also in their networking capabilities. This leads to increased costs and heightened complexity in managing these sprawling infrastructures.
In traditional setups, network hardware and software were tightly coupled, meaning purchasing a switch, router, or firewall meant running the vendor’s proprietary software on the hardware. Recognizing this limitation, larger cloud providers began exploring alternatives. They discovered that by using commercial off-the-shelf hardware and developing their own software, they could achieve significant cost savings without sacrificing performance. However, this separation of software from hardware didn’t fully tackle the underlying complexity of network management.
IEEE 802.1BR: Simplifying Network ArchitectureModern cloud data centers typically adopt a tiered architecture, often structured as a fat-tree or leaf-spine topology. Within this framework, racks are connected via Top-of-Rack (ToR) switches to upstream backbone switches. While ToR switches handle basic traffic aggregation tasks, they often require high-end, energy-intensive equipment, leading to elevated costs and maintenance challenges.
The IEEE 802.1BR standard introduces port extension technology aimed at simplifying this architecture. By replacing ToR switches with port extenders, racks can be directly connected to upstream switches, eliminating the need for numerous switches at the rack level. This shift reduces the complexity of switch management and streamlines operations.
Despite its promise, not all current port extenders fully leverage the benefits of the 802.1BR standard due to reliance on outdated components tied to legacy switching products. This limits the potential cost and power advantages of adopting this architecture.
The Future of Network DisaggregationAlthough many existing port extenders support 802.1BR, they often utilize outdated components that don’t fully embrace the standard. Consequently, the full cost and power-saving potential of the new architecture remains unrealized.
Marvell’s Passive Smart Port Extender (PIPE) products are uniquely designed to align with the 802.1BR standard and optimize the architecture. PIPE solutions are compatible with upstream bridge switches from leading OEMs, enabling fanless, cost-effective deployments in cloud data centers. This results in substantial upfront savings and ongoing operational cost reductions. Additionally, power consumption and switch management complexity can be decreased by an order of magnitude.
The first wave of network disaggregation focused on separating switch software from hardware. The 802.1BR port extension architecture represents the next wave, where ports are decoupled from the switches managing them. This modular network approach promises further cost reductions, lower energy consumption, and simplified network management.
As cloud computing continues to evolve, innovations like 802.1BR and advanced port extenders will play critical roles in ensuring efficient, scalable, and cost-effective network infrastructures. The journey toward smarter, more agile networks is just beginning.

Enhanced Article: The Lifeline of Electricity: Understanding Electrical Wires and Cables
Wires and cables stand as fundamental components in constructing the modern world. Like veins in a body, these "Electrical Wires" form the circulatory system of our electric infrastructure, quietly distributing power to residences, businesses, and factories alike.
Understanding the Building Blocks of Electrical Wiring:Fundamentally, "Electrical Cable" and wires are based on a common blueprint: one or more conductors, insulated and then protected by a jacket. Yet, the diversity in conductor sizes, insulation types, and jackets yields a multitude of "Electric Cables," each crafted for particular requirements.
Within the "Building Wires" category- synonymous with house wiring-you'll find types like NM-B and THHN/THWN. These varieties are pivotal to electricity distribution in both homes and commercial buildings, ensuring that power reaches outlets, lighting, and various devices. In contrast, power cables take on the more strenuous task of delivering electricity to industrial machinery due to their thicker conductors and more durable insulation. Meanwhile, AC or armored cables boast an additional metallic protection, making them ideal for industrial applications or burial beneath the surface where physical protection is paramount.
For information transmission, communication cables step into the spotlight. These are designed for data rather than power, with telephone wires, coaxial lines for internet and television, and Ethernet cables for computerized systems.
How to Choose the Right "Electrical Wire" or "Electric Cables":The path to the correct wire for any electrical system involves multiple steps:
Application: Clearly, the role of the "Electric Cable" dictates its construction. Appliances drawing significant power require suitably robust cables capable of safely managing the electric current.
Circuit Type: Given that electrical networks are segmented into circuits with specified roles, each demands a compatible type of "Building Wire". For instance, the "Electrical Wires" used in branch circuits-those directly connected to sockets and illumination-differ from their counterparts in feeder circuits, which essentially guide power from the main distribution point.
Location Requirements: Let's not overlook local building regulations, which often mandate the use of a certain grade or type of "Electrical Cable" depending on the environment-a waterproof solution for damp or subterranean settings, for example.
Adhering to these protocols and understanding the intricacies of "Electrical Wires" and cables guides you towards an informed selection, vital for any sound electrical system. It's through this harmonious blend of technical knowledge and practical application that the lifeline of electricity is maintained.
Generally, Electric Cables are Copper Wire conductor, PVC Insulation, XLPE Insulation or LSOH Insulation and others, with PVC sheath or LSOH Sheath. There are Circular Cable or Flat Cable.
We supply lots of those Wires as per IEC 60227, BS 6004, AS/NZS 5000.2, VDE, SABS and other requirements.
