Satellite Simulators
Simulator 3 : v3.1.2 Features Upgrade Available
12/November/2007 19:38
Vocality is pleased to announce some
enhancements to the new SIM3 IP Satellite
simulation product.
• IP Simulation is enhanced with the new IP Scripting feature. This allows parameters such as the error rate, error type and delay to be varied over time and so more closely represent real-world scenarios.
• Packet-based triggers allow the IP Simulation parameters to be automatically changed when packets of particular types occur. So for example, when a particular TOS value, protocol type or address is detected in the data the behaviour of the unit can be changed. This is an extremely powerful feature that allows the SIM3 to operate interactively with the traffic and thereby emulate a network reacting to stimuli.
• The Ethernet MTU (Maximum Transmission Unit) size can now be configured. This allows the unit to simulate the effect of a network with a smaller than standard MTU and to either fragment or discard large packets as a result. Simulation impairments may be applied to the packet fragments - for example, to cause re-sequencing or to discard them.
• A new option “Enqueue Bandwidth”: controls the amount of data buffered on each profile – with the option to overflow to a different profile (or discard) if the bandwidth is exceeded. This allows the simulation of (for example) a network with a limited amount of high-priority bandwidth, where traffic overflows to a lower-quality class when a bandwidth limit is exceeded.
• The IP Simulation bandwidth management options are improved with the option to discard oldest or newest packet(s) if the queue length is exceeded.
• Intelligent fan control – the fan now comes on at power up by default but then turns off until the unit reaches a maximum internal temperature.
• The Vocality TFTP firmware download facility used on the larger rackmount mux/routers is now available on the SIM3, dramatically improving the upgrade time.
