Transfer CFT 3.6 Users Guide Save PDF Selected topic Selected topic and subtopics All content 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: Global Class Partner Session 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) (SEND/RECV, CFTSEND/CFTRECV, CFTPART, CFTPROT, CFTNET) In server mode, the initial negotiation occurs through the corresponding CFTPROT bandwidth class A partner can be present in two bandwidth classes, but in that case the system will act as if two separated partners exist Related topics About bandwidth control Bandwidth use cases Related Links
