Configuring Redundant Links Between Sites
The Solaris 8 operating environment offers IP multipathing. This feature permits a
Solaris host to group multiple physical network interfaces into a single logical
interface. Redundancy between paths permits transparent operation in the event of a
failure anywhere on the path including failures of network interface cards, links,
switches and routers.
This feature also provides the Sun SNDR software with the transparent means for
surviving link failures. It provides the ability to aggregate bandwidth across the
physical interfaces permitting a pair of ATM 622 Mbit links to operate as one logical
1244 Mbit link with resiliency.
Link Security
Solaris 8 operating environment offers IPsec, the industry standard form of
integrating encryption and authentication mechanisms into standard IP
internetworking. A Solaris 8 host can authenticate and encrypt traffic on a
conversation-by-conversation basis.
Additionally, Sun offers SunScreen
TM
software technology that permits both
encryption and authentication of IP traffic. Coupled with the Sun SNDR software,
SunScreen software can provide an additional level of security to the data being
transmitted between sites. SunScreen software uses public key encryption
technology to guarantee that traffic is strongly encrypted. The public key mechanism
is also used to authenticate that the sender of the traffic is the correct entity.
SunScreen software is normally configured at the edge of the data center network.
Of course, cooperating SunScreen software is required at each data center.
