Managing bandwidth sessions
This topic describes bandwidth session concepts. For parameter details, see the topic About bandwidth control.
In Transfer CFT, bandwidth control can occur at the following levels:
The use of minimal dynamic control implies that:
- Netbands can be reconfigured dynamically
- Partners can change netbands, but the new class only applies to new transfers
Every session, as shown here, is linked to a partner. Partner are linked to a netband, which can optionally link to a parent netband.
- n= netband
- p = partner
- s = session
Within a class (netband, partner, session), the bandwidth is shared evenly, and is proportionate to its relative rate. This ensures fairness between sessions for a partner, between partners in a netband, and between netbands in a netband. The following rules apply:
- A maximum rate can be specified for a partner, session, or netband level
- Every session and partner in a given bandwidth class (netband) have the same properties: rate, max-rate (in/out)
- A netband can be specified at each level (SEND/RECV, and transfer properties)
