Note

In the current implementation, the “send” and “receive” buffer size for TCP packets is restricted to 64 kilobytes. Due to this limitation, the SBC cannot handle traffic where the product of the TCP packet size (measured in kilobytes) and the processor rate (measured in cycles per second) exceeds 64. For example, if the packet size is 3 kilobytes and the processor rate is 25 cycles per second, the product is 75 - which is greater than the TCP buffer size. If the TCP buffer overflows, the SBC resets the connection. This is particularly important when the packet sizes are large, as in case of packets containing the INFO header that bloats the packet sizes.
