|
Field |
| Description |
|
|
|
Packet headers |
| Data structure that defines and controls an aggregation of data |
|
| structures, collectively known as a packet. Includes information |
|
| about every packet in the system. |
|
|
|
Particle Pools |
| Data structure that describes a particle and may be chained to other |
|
| particles in a linked list. Includes information about the actual data |
|
| of the packet and other particle headers in this packet if present in |
|
| this packet. |
|
|
|
Particle clone |
| Duplicate particle header that points to a previously allocated |
|
| particle. Differs from a particle header in that a particle clone shares |
|
| the particle with another particle header. |
|
| |
Packet Feature Specific | Scratch pad shared among the features in the packet path, listing | |
Variable (FSV) |
| hangs of the packet header. |
|
|
|
Packet trace |
| Data associated with the packet header to help tracing a packet in |
|
| the system. |
