NAT (SNAT) Support
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.
Loadbalancing of Gateways
Problems associated with Enterprise WAN connectivity
The utilization of multiple ISP uplink gateways
requires advanced route loadbalancing and failover 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
failover procedure is out of the question.
The SysMaster solution
SysMaster allows complete bandwidth aggregation,
gateway load balancing (multi-path WRR), and gateway failover. If
any active gateway changes its state to disabled, it is isolated
and removed from rotation. In all cases, only available gateways
are used to route traffic. Furthermore, SysMaster allows dynamic
gateway weight assignment to dynamically manage gateway utilization
and traffic flow without the need to reconfigure routes. SysMaster
is the only router that allows dynamic management of uplink gateways
in corporate and ISP environment.
- Bandwidth Aggregation - supports unlimited
number of uplink gateways to multiply the overall system throughput;
- Gateway Failover - 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.
Unique Functionality
SysMaster is the only router that allows dynamic
route and gateway management to provide complete gateway failover
and static/dynamic loadbalancing. The device can control the weight
assignments for each individual gateway dynamically without manual
intervention. The weight for each gateway to be used for the route
is initially assigned by the network admin, and then (if selected)
dynamically controlled using a third party agent, utilization monitoring,
advanced rules.
- 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.
Traffic Loadbalancing and Failover
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.
Outbound Traffic Loadbalancing and Failover
SysMaster allows dynamic control of all outbound
gateways to isolate disabled routes from traffic routing. Utilizing
proprietary mechanism of WAN device controls and L3/L7 gateway health
checks, the device quickly responds to changed traffic conditions
and dynamically changes weight assignments to its managed uplink
gateways. SysMaster fully supports static and dynamic Weighted Round
Robing (WRR) loadbalancing for outbound traffic on a per session
basis.
Inbound Traffic Loadbalancing and Failover
SysMaster utilizes a proprietary Advanced DNS algorithm
to loadbalance and failover inbound traffic via DNS responses. The
device provides intelligent DNS responses that are based on server
utilization and performance, physical client proximity (via BGP
client), and geographical client location (via proprietary geographical
IP segment database). Utilizing Advanced DNS services, the appliance
allows dynamic global loadbalancing for servers and routes.
Transparent Network Integration
SysMaster supports Route Bridge functionality to
allow transparent integration into existing networks. SysMaster
installation does not require changes in routing tables and gateways
of existing network devices. In many cases, SysMaster will replace
an existing Ethernet cable and act as a transparent router to allow
simplified environment integration.
SysMaster as an Access Router
Delivering extensive set of supported routing protocols
such as RIP, BGP and others, together with the high-performance
packet forwarding, allows system administrators to build solid network
solutions upon the SysMaster Routing/Gateway Module. The QoS module
can be used to add functionality that can be positioned as a highly
flexible edge router supporting DiffServ IP QoS.
