GNU debugger that enables you to debug your program in C source code level.

GUI

Graphical user interface.

I

IPC

Interprocess communication software mechanism that provides a means to communicate between processes that run in a domain under the Netra DPS Lightweight Runtime Environment (LWRTE) and processes in a domain with a control plane operating system.

Message Block. A data structure that carries packet information.

N

NAK

Negative-Acknowledge is sent by a station to indicate that an error was detected in the previously received block and that the receiver is ready to accept retransmission of that block.

Netra DPS

Netra Data Plane Software Suite. In this document, this suite is also referred to as Netra DPS.

Netra DPS Runtime API

Consists of portable, target-independent abstractions over various operating system facilities such as thread management, heap-based memory management, time management, socket communication, and file descriptor registration and handling.

NIU

P

parked

A parked strand does not consume any pipeline cycles (an inactive strand).

PDSN

The Packet Data Serving Node, or PDSN, is a component of a CDMA2000 mobile network. It acts as the connection point between the Radio Access and IP networks. This component is responsible for managing PPP sessions between the mobile provider core IP network and the mobile station.

U

UDP

User/Universal Datagram Protocol.

UltraSPARC T1

Processor that employs chip multithreading, or CMT, which combines chip multiprocessing (CMP) and hardware multithreading (MT). This processor creates a SPARC V9 processor with up to eight 4-way multithreaded cores for up to 32 simultaneous threads.

UltraSPARC T2

Processor that is the second generation of the CMT processor. In addition to features found in UltraSPARC T1, UltraSPARC T2 dramatically increases processing power by increasing the number of hardware strands in each core. UltraSPARC T2 includes on-chip 10G Ethernet and crypto accelerator.
