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
Additionally, Sun offers SunScreenTM 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.
