Key Terms

pam4, link layer retry, credit-based flow control, link layer discover protocol

4 terms

pam4 technical

"high-speed PAM4 and legacy NRZ interfaces"

PAM4 is a digital signaling method that sends information by using four distinct voltage or light levels instead of the usual two, letting each transmitted symbol carry two bits of data. Think of it like a radio knob with four clear positions instead of just on/off; it boosts transmission speed without needing extra wires or spectrum but is harder to read reliably, so it matters to investors because it drives demand for higher-performance chips, better cables and optics, and can affect product costs, margins and upgrade cycles in networking and data-center markets.

link layer retry technical

"Link Layer Retry (LLR)"

A link layer retry is an automatic attempt by a network device to resend a data packet when the first delivery over a local network link fails or isn’t acknowledged. Like a mail carrier trying again after a delivery attempt fails, these retries keep connections reliable but can add delay and reduce overall throughput; investors watch them because high retry rates can signal hardware, firmware, or congestion problems that affect a product’s performance and customer experience.

credit-based flow control technical

"Credit-Based Flow Control (CBFC)"

A network congestion-control method that lets a receiver grant the sender a limited number of “credits” representing how much data the receiver can accept, and the sender can only transmit when it holds enough credits. Like a parking-attendant handing out spaces, it prevents senders from overwhelming receivers and reduces packet loss, latency, and retransmissions; investors see it mentioned because it directly affects a product’s throughput, reliability, and scalability in data-center and storage markets.

link layer discover protocol technical

"Link Layer Discover Protocol (LLDP)"

A Link Layer Discovery Protocol is a network protocol that runs on the data-link (Layer 2) level allowing switches, routers, servers and other devices to advertise their identity, capabilities and connection details to directly connected neighbors. Investors may care because use of this standard improves interoperability, troubleshooting, network inventory and security monitoring, which can affect product compatibility, deployment costs and operational reliability for companies that build or operate IT infrastructure.
