AA-ISA provides, at the AA partition level, traffic volume visibility of the Layer 3 protocols used to transport the different Layer 4 protocols. These include a traffic volume break down of TCP, UDP and Non-TCP-UDP carried by IPv4 and IPv6, DS_Lite, 6to4/6RD, GTP, and Teredo protocols.
Traffic-type statistics are broken down by ‟family” and ‟protocol”:
Family includes IPv4, IPv6, DS-Lite, 6RD/6to4, Teredo, and GTP (IP v4/v6 in v4/v6).
Protocol includes TCP, UDP, and Other.
Therefore, AA-ISA traffic type record provides a collection of 15 sets of traffic volume (bytes) statistics figures, as shown in Table: Families and protocols
| Family | Protocols |
|---|---|
|
IPv4 |
TCP, UDP, Other |
|
IPv6 |
TCP, UDP, Other |
|
DS-Lite |
TCP, UDP, Other (IPv4 tunneled inside IPv6) |
|
6to4/6RD |
TCP, UDP, Other (IPv6 tunneled inside IPv4) |
|
Teredo |
TCP, UDP, Other (IPv6 tunneled inside IPv4 and UDP) |
|
v4inv4GTP |
TCP, UDP, Other (IPv4 tunneled inside IPv4 GTP) |
|
v4inv6GTP |
TCP, UDP, Other (IPv4 tunneled inside IPv6 GTP) |
|
v6inv4GTP |
TCP, UDP, Other (IPv6 tunneled inside IPv4 GTP) |
|
v6inv6GTP |
TCP, UDP, Other (IPv6 tunneled inside IPv6 GTP) |
These statistics are always counted. There is no configuration required to enable/disable tracking. However, the operator has the option to enable/disable export of these statistics via XML.
Table: AA-partition traffic type statistics lists the statistic record fields per AA partition.
