RFC 3522

今天把用于 FreeBSD 7-CURRENT的RFC 3522实现发到邮件列表之后，Mike告诉我，爱立信对Eifel Detection算法拥有专利，并禁止非开源产品无偿使用此专利。

还在老地方。RFC 3522 (Eifel Detection)是一项用于避免TCP中不必要的重传的技术。

关于FreeBSD近期希望完成的网络协议栈方面改进，请参见 Wiki。

I will release third (more or less unstable) release ISO if nothing will prevent me from doing that :-) The latest delphijfork includes several new features, which is tend to exhibit new technologies and possiblities of FreeBSD:

• An implementation of RFC 3522 ported from DragonFlyBSD
• An implementation of Early Retransmission ported from DragonFlyBSD

Also, FreeBSD-CURRENT has several new features, including:

• In progress import of binutils 2.15
• pf 3.5. Including several new features and works better with spamd.
• better ACPI support

I have posted it as rev. 1.5 of <research.delphij.net/freebsd/rfc3522.diff>. Some minor comestic changes has gone into the patchset, as junsu pointed out. I’ll remove the unrelated ones soon.

I have ported Jeffrey Hsu’s RFC3522 implementation in DragonFlyBSD to FreeBSD. Check https://research.delphij.net/freebsd/rfc3522.diff.
