Using NAT configuration, SysMaster can provide secure Internet connectivity to all computers in the Local Area Network requiring just one public IP address, sparing investments on a block of IP addresses and increasing overall network security.
Load balancing of Gateways
Problems associated with Enterprise WAN connectivity
The utilization of multiple ISP up link gateways requires advanced route load balancing and fail over to ensure uninterrupted connectivity of corporate offices and service centers. Current routing protocols are limited in terms of bandwidth aggregation and do not support dynamic weight allocation to gateways. In most cases unavailable routes are not recognized by the access router and thus proper gateway fail over procedure is out of the question.
The SysMaster solution
- Bandwidth Aggregation - supports unlimited number of up link gateways to multiply the overall system throughput;
- Gateway fail over - allows isolation of 'dead gateways' and traffic routing through alternative gateways;
- Global DNS Load Balancing - features stand-alone DNS server that provides scalability and load balancing of inbound (ingress) routes for all web, mail, and other Internet servers;
- Ingress/Egress Load Balancing - provides two-way load balancing services for multiple uplinks such as xDSL, T1, T3, OC-3/12/48 and Ethernet.
- Third-party agent. The information is read by SysMaster from a third-party agent to dynamically allocate new weight to each individual gateway.
- Internal network device utilization monitoring. The device traffic is evaluated against the physical device parameters to provide dynamic aggregated bandwidth management.
- Set of Advanced Rules. SysMaster completely supports advanced object management rules based on traffic volume, time-of-day, device-status checks.
Large enterprises can have multiple xDSL, T1, T3, OC-3/12/48, and Ethernet gateways to access the Internet or implement corporate VPN networks and extranets. In this environment, SysMaster can be used to dynamically aggregate bandwidth and distribute the load of a network (to which it serves as a gateway) among the higher level corporate gateways thus delivering high level of efficiency. In order to effectively match the available resources allocated for each managed gateway, SysMaster assigns a performance weight to each managed gateway which reciprocally reflects the volume of traffic being forwarded through the respective gateway. The SysMaster also actively monitors all available gateways to allow for 'dead gateway discovery', and redirect traffic through alternative gateways.
