Network

/ˈmʌltiˌkæst/

noun — "sending data to multiple specific recipients simultaneously."

/siː-dʌbəl-juː-ɑːr/

n. “A TCP header flag used to indicate that congestion has been acknowledged and the sender can resume normal transmission.”

/iː-siː-ɛn/

n. “A mechanism in TCP/IP networks for signaling congestion without dropping packets.”

ECN, short for Explicit Congestion Notification, is a feature of modern IP networks that allows routers and endpoints to signal network congestion to senders proactively. Instead of relying solely on packet loss to indicate congestion, ECN marks packets to alert the sender to slow down, improving network efficiency and reducing latency.

/ˌviː-piː-siː/

n. “A logically isolated virtual network in the cloud that allows secure control over networking and resources.”

VPC, short for Virtual Private Cloud, is a service provided by Amazon Web Services (AWS) that lets users create a private, isolated section of the cloud. Within a VPC, you can define IP address ranges, subnets, routing tables, and network gateways, giving fine-grained control over how resources communicate and connect to the internet or other networks.

/iː-siː-iː/

n. “A TCP header flag used to indicate Explicit Congestion Notification.”

In the context of the Transmission Control Protocol (TCP), ECE (short for ECN Echo) is a flag that signals the detection of network congestion without dropping packets. It works in conjunction with Explicit Congestion Notification (ECN) mechanisms to provide more efficient and controlled congestion management.

n. “A TCP control flag indicating that certain data should be treated as urgent.”

In the context of the Transmission Control Protocol (TCP), URG (short for urgent) is a flag used to indicate that some of the transmitted data in a segment is urgent and should be prioritized by the receiving application. The flag works alongside the Urgent Pointer field in the TCP header to specify the position in the data stream where the urgent data ends.

Key characteristics of URG include:

/pʃ/

n. “A TCP control flag that instructs the receiving end to push buffered data to the application immediately.”

In the context of the Transmission Control Protocol (TCP), PSH (short for push) is a flag used to signal that the data being sent should be delivered to the receiving application immediately, without waiting to fill the buffer. This helps reduce latency for time-sensitive communication, ensuring data reaches the application as soon as possible.

Key characteristics of PSH include:

/fɪn/

n. “A control flag in TCP indicating the sender has finished sending data.”

In the context of the Transmission Control Protocol (TCP), FIN (short for finish) is a flag used to signal the termination of a TCP connection. When a device sends a FIN packet, it indicates that it has no more data to transmit, initiating the connection teardown process while allowing any remaining data to be received.

/diː-eɪtʃ-siː-pi-viː-sɪks/

n. “The protocol that automatically assigns IPv6 addresses and settings on a network.”

DHCPv6, short for Dynamic Host Configuration Protocol for IPv6, is a network protocol designed to automatically provide IPv6 addresses and configuration information to devices on an IPv6-enabled network. While similar in purpose to DHCPv4, DHCPv6 is specifically adapted to handle the vast address space and unique features of IPv6.

Key characteristics of DHCPv6 include:

/diː-eɪtʃ-siː-pi-viː-foʊr/

n. “The protocol that automatically hands out IPv4 addresses on a network.”

DHCPv4, short for Dynamic Host Configuration Protocol for IPv4, is a network protocol used to automatically assign IPv4 addresses and other configuration parameters (like subnet mask, default gateway, and DNS servers) to devices on a network. This eliminates the need for manual IP address assignment and ensures efficient address management in networks.

Key characteristics of DHCPv4 include:
