4.2.2.3 Window Size: RFC-793 Section 3.1

The window size MUST be treated as an unsigned number, or else large window sizes will appear like negative windows and TCP will not work. It is RECOMMENDED that implementations reserve 32-bit fields for the send and receive window sizes in the connection record and do all window computations with 32 bits.

DISCUSSION:

It is known that the window field in the TCP header is too small for high-speed, long-delay paths. Experimental TCP options have been defined to extend the window size; see for example [TCP:11]. In anticipation of the adoption of such an extension, TCP implementors should treat windows as 32 bits.
