NetBSD: Ismét Internet2 Land Speed rekord

En ugy tudom, hogy a Juniper kemenyen hardveres router, es csak az osszetevok monitorozasat, osszehangolasat vegzi a FreeBSD. A route-olast nem szoftveresen csinaljak.

A Juniper azt allitja, hogy a JunOS FreeBSD alapu, de jelentosen atirtak. Arrol nem beszelnek, hogy mennyi kodot adtak vissza a fejlesztoknek. Ami a szomoru, hogy egy arva sor nincs a juniper.net-en arrol, hogy valaha FreeBSD-bol indultak. Persze melyen egy PDF-ben azert megemlitik...

"FreeBSD provides the foundation for the development of a next-generation routing

architecture that has the ability to scale and support the tremendous growth projections for the

Internet. FreeBSD is specifically designed to run on ubiquitous Intel processors. It is very

stable, has a mature networking heritage by virtue of its ancestor running on the Internet since

the early 1970s, and contains a significant code base that can be leveraged in terms of a kernel,

file systems, user accounts, and security.

However, Juniper Networks enhanced and rewrote significant portions of FreeBSD because it

was initially designed to run on host systems supporting a very limited number of network

interfaces. Routers, on the other hand, have significantly more physical interfaces as well as

numerous subinterfaces and a much larger routing table. In addition, the majority of the

networking code was discarded and replaced with industrial-strength implementations that

were capable of withstanding the tremendous stresses imposed by the operational Internet.

The Juniper Networks engineering staff was given the rare opportunity to take their years of

practical Internet routing experience and design a routing architecture from the ground up

without being constrained by the conditions imposed by a legacy routing architecture. This

meant that they could optimize their data structures, plan for a large number of virtual circuits,

and design for efficient storage and searching of huge routing tables. They were free to

implement the latest technology developments supporting traffic engineering and

differentiated service levels and were allowed to place particular emphasis on the design of a

serviceable user interface and a powerful policy definition language."

Ja, akit erdekel a PDF, itt megtalalja.

Nem kerdojeleztem meg, hogy van koze a FreeBSD-hez. Annyit mondtam, hogy _en ugy tudom_, hogy nem a FreeBSD halozati stack route-ol. Mintha valaki azt mondta volna, hogy szoftveresen mar nem lehet ekkora adatmennyiseget route-olni...
