Application specific integrated circuits (ASICs) explained
Application specific integrated circuits (ASICs) are microchip processors specialized to a particular task or application, such as handling networking functions within an enterprise switch.
In enterprise network switches and access points, ASICs handle critical networking tasks such as packet forwarding, traffic management, and security filtering at high speeds. These customized chips are embedded directly into network hardware to process network data rapidly and efficiently, significantly outperforming general-purpose and configurable processors for specific networking functions.
What are the key components of application specific integrated circuits (ASICs)?
- Packet processor: Manages rapid packet forwarding and filtering
- Traffic management engine: Handles traffic prioritization, shaping, and Quality of Service (QoS)
- Buffer memory: Temporarily stores data packets to manage network congestion
- Security modules: Implements network security protocols and inspection
- Management interface: Provides communication pathways for ASIC management and control
What are the benefits of an application specific integrated circuit (ASIC)?
- Increased throughput with full, line-rate performance on outgoing ports and packet forwarding
- Reduced latency with faster processing, packet buffering, and flexible queue configurations
- Greater efficiency that consumes less power and generates less heat for the same workload
- Better reliability with less points of failure due to specialized, streamlined design
- Stronger security with optimized handling of security functions like encryption and anomaly detection
- Enhanced programmability for rapid innovation, instrumentation, automation and telemetry
What are the best practices for application specific integrated circuits (ASICs)?
- Assess network requirements: Clearly define performance, security, and scalability needs before ASIC implementation
- Choose ASIC-equipped hardware wisely: Select network devices with ASICs tailored to specific network workloads and applications
- Regular firmware updates: Ensure the ASIC firmware is consistently updated for optimal performance, compatibility, and security
- Monitor ASIC performance: Continuously monitor ASIC health and efficiency through network analytics and telemetry
- Maintain vendor support and documentation: Stay informed on vendor updates, support policies, and technical documentation to resolve issues promptly and maintain network stability
Why should enterprises care about application specific integrated circuits (ASICs)?
Enterprise network solutions that use an application specific integrated circuit (ASIC) in the design of their products are better positioned to deliver on key strategic outcomes, offering:
- More flexibility to prioritize business requirements and customer requests
- Innovation autonomy to build the right technology for current and future use cases
- Greater agility for accelerated time to market of new and reimagined solutions
- Better uniformity for a consistent and seamless experience across the portfolio
