c'est quoi ce c/c de sale Mr Vach?

c'est du LaTeX pas compilé c'est tout

merci j'avais vu

c'est moche latex ^^

je préfère le polyuréthane, c'est mieux niveau sensations.
pas d'allergie, plus fin, plus résistant

2.6 Flow Control, Bandwidth Limiting, Traffic Control and Switch buffer Overrun

When involved in IP infrastructure and DDP you will hear phrases such as Flow Control, Bandwidth Limiting, Traffic Control, buffer in switches and buffer overrun.
So some explanation is needed here.
Flow Control is part of the 802.3x protocol and when enabled allows the receiver to report to the sender to hold the next IP packet.
In an uplink situation it can be that each 1GbE port on the switch asks to delay sending a packet resulting in a substantial decrease in 10 GbE bandwidth.
Hence standard Flow Control should be off on the 10 GbE link in a 1 GbE switch with 10 GbE uplink.
Can Bandwidth Limitation (BWL) help to control the bandwidth? BWL is a technology built-in in the iSCSI part of the DDP and schedules iSCSI requests in the iSCSI initiator on the desktop.
The bandwidth is scheduled standard at a 100 ms granularity.
This means that in the situation where you have a 1 GbE switch with 10 GbE uplink the data read requests for example are still transmitted from the DDP at 10 GbE speed.
To give an example suppose the desktop request 1 MB of data.
At 10 GbE it is transmitted from the DDP at 1200 MB/s.
That takes less then 1ms transmission time into the switch and takes 10 ms to get to the desktop.
All much faster then the BWL scheduling is. BWL is there to prevent overloading drive access.
A desktop can take up all the drive access time when they are allowed for example to copy or render at the highest speed possible.
BWL does not help preventing switch buffer overrun.
Traffic Control on the contrary allows packet transmission scheduling on TCP/IPStack level.
This happens on packet scale. Its parameters are set for a particular IP range.
In the situation with the 1 GbE switch with 10 GbE uplink from the onset the packets for each desktop IP address is scheduled at a rate of say 100 MB/s max.
Thereby emulating a 1GbE line. So 1500 byte packages for a particular desktop would be transmitted with 15 us interval instead of 1,5 us interval with other packets interleaved.

2.7 Subnet and VLAN
DDP is a system with mutiple ethernet ports. Just like any computer with multiple ethernet ports each ports needs to have its own unique subnet.
A 6 subnet is defined at the IP address level with the (sub)netmask.
Subnets are transparant for switches and both layer 2 or layer 3 switches can be used with the DDP.
Layer 2 switches have the ability to create VLANs. VLANs are based on the lower level physical MAC address of the ethernet ports.
Both subnets and VLAN can be used simultaneously.
