Emerging Technologies announces the availability of multi-line load balancing features for it sychronous adapters for FreeBSD, Linux and BSD/OS. The new feature allows up to 8 lines or frame relay DLCIs to be "bundled" together in load balancing or fallback/backup configurations. Load balanced lines are bundled with a simple utility that builds stacks of "pipes" which are automatically balanced within the supplied drivers. Synchronous lines may be balanced along with frame relay dlcis to create simply yet powerful multi-path redundant networks. Individual lines or DLCIs can also be designated as "fallback" only, in which case traffic will be re-routed to those lines only if the primary pipe is out of service. The software also supports "directed" load-balancing, which allows administrators to target traffic from specifc sources to a specific pipe. As an example, an installation with 2 T1 lines could have all of its dial-up traffic routed to one T1 and all local and serial line traffic routed to the other. This can be used to create priority pipes or simply to assign bandwidth on a source by source basis. The next release will allow specific types of traffic to be routed to a particular pipe, such as WEB and FTP traffic to one pipe and TELNET and domain traffic to another. Information about these new features is available at www.etinc.com.
