[lwip-users] Need Help for "Configuration for lwIP"

[GICINDIA]

Hi,
I have done following configurations for lwip but i m not sure whether it is
correct or not.

1st Configuration - Considering MEM_SIZE = TCP_WND + TCP_SND_BUF

#define MEM_SIZE                        (8 * 1024)    
#define TCP_WND                         2048
#define TCP_MSS                         1024
#define TCP_SND_BUF                   (6 * 1024)
#define TCP_SND_QUEUELEN          (4 * (TCP_SND_BUF/TCP_MSS))
#define PBUF_POOL_BUFSIZE               256
#define PBUF_POOL_SIZE              ((TCP_WND + TCP_SND_BUF) /
PBUF_POOL_BUFSIZE) 

2nd Configuration - Considering MEM_SIZE = TCP_SND_BUF + 1024

#define MEM_SIZE                        (7 * 1024)    
#define TCP_WND                         2048
#define TCP_MSS                         1024
#define TCP_SND_BUF                   (6 * 1024)
#define TCP_SND_QUEUELEN          (4 * (TCP_SND_BUF/TCP_MSS))
#define PBUF_POOL_BUFSIZE               256
#define PBUF_POOL_SIZE              ((TCP_WND + TCP_SND_BUF) /
PBUF_POOL_BUFSIZE)

Can any one tell me which configuration (1st or 2nd) is correct one or none
of these?
Please suggest any good document for reference to understand the
configurations for lwip.


Regards,
Asma.
