What are receive buffers?
Receive Buffers: The buffer size of system memory that can be used by the adapter for received packets, which can be increased to help improve the performance of outgoing network traffic, but it consumes system memory.
What is a transmission buffer?
The function of the transmission buffer is to keep the output rate of the encoder fixed. If the buffer starts filling up faster than the transmission rate, it sends a message back to the transform coder to reduce the output from the quantization.
Should I disable priority and VLAN?
Priority & VLAN is automatically enabled when you set up a VLAN on the VLAN tab. You cannot disable tagging because tagging is required for VLANs….Advanced Driver Settings for Intel® Ethernet 10 Gigabit Server Adapters.
| Default | Priority & VLAN Enabled |
|---|---|
| Range | Priority & VLAN Disabled, Priority & VLAN Enabled, Priority Enabled, VLAN Enabled |
Should I enable priority and VLAN?
What should my transmit buffer be?
Look for ‘Receive Buffer’ and ‘Transmit Buffer’ in the list. The recommended size is either 512 or maybe even 1024 – you can go up to 2048 if you have enough RAM to support it. Ensure that the transmit buffer is double the receive buffer. Just remember, that going below 256 will lead to dropped packets.
What does Force Master Mode do?
Some multi-port devices can be forced to master mode. If forced to master mode, the device can either disconnect or downshift to a 100-Mbps link.
Why is my LAN only 100mbps?
This is common. Incidents such as rolling over the cable with an office chair, or stepping on it, or closing a door on it, can all cause a Cat 5e cable to revert to 100 Mbps link speeds when it was previously working at Gigabit speeds. Try different ports on your access point (hub, switch, router).
What happens when TCP receive buffer is full?
If the receive buffer is full and the other end of the TCP connection tries to send additional data, the kernel will refuse to ACK the packets. This is just regular TCP congestion control.
What is TCP buffer?
Simply put, a TCP Receive Window is a buffer on each side of the TCP connection that temporarily holds incoming data. The data in this buffer is sent to the application, clearing more room for incoming data.
What is a transmit/receive buffer?
My understanding of what a transmit/receive buffer is largely related to ethernet systems, where some data is stored in the buffer before the whole data is transmitted.
What is the difference between software buffers and hardware buffers?
There are software buffers and hardware buffers. The UART hardware peripheral has hardware buffers, a rx buffer where received data is waiting to get handled by the program, and a tx buffer where data is waiting for the MCU to transmit it (a tx complete flag will get set). In some MCUs these are just 1 byte large each.
Do I need to increase buffer size?
I’m sure that’s a horribly inaccurate analogy that someone will facepalm at, but its what makes sense to me. oh, and you would probably only need to increase buffer size if you had really heavy network traffic on your computer.
What is a TX buffer in UART?
The UART hardware peripheral has hardware buffers, a rx buffer where received data is waiting to get handled by the program, and a tx buffer where data is waiting for the MCU to transmit it (a tx complete flag will get set). In some MCUs these are just 1 byte large each. Others have a larger rx buffers following a FIFO principle.
