Subject: [PATCH] tcp: make cubic the default
Date: Wed, 20 Sep 2006 13:32:58 -0700	[thread overview]
Message-ID: <20060920133258.36ff42ce@localhost.localdomain> (raw)
In-Reply-To: <20060920081704.GA1812@outpost.ds9a.nl>

Change default congestion control used from BIC to the newer CUBIC
which it the successor to BIC but has better properties over long delay links.
