EL860 ACM Controller, Shaper and Encapsulator
The Newtec EL860 Shaper and Encapsulator is a unique appliance that combines a number of advanced multilevel IP traffi c policing and real time shaping functionalities with an industry leading DVB-S2 IP encapsulator and a DVB-S2 modulation parameter controller. The EL860 enables Constant Coding and Modulation (CCM), Variable Coding and Modulation (VCM) and Adaptive Coding and Modulation (ACM) implementations in the forward link of satellite star services applications, such as IP trunking networks. The EL860 is to be installed in front of a DVB-S2 modulator, at the hub side of such network.
As corporate and private users demand more and more bandwidth, service providers need to apply sophisticated traffic policing and shaping mechanisms in order to ensure that the available bandwidth is distributed in the most appropriate manner among the users of the satellite network.
With the EL860 CSE it is possible to restrict the maximum given peak bandwidth for each user, for groups of users and for groups of remote sites. Moreover, guaranteed bandwidths and weighting factors for the distribution of the overall available bandwidth of a satellite link can be configured with the same granularity. The traffic policing engine also allows the distribution of available bandwidth among services in order to e.g. prioritize VoIP traffic. Both, the hierarchical grouping structures as well as the traffic policing rules can be on-the-fly reconfigured without causing any downtime.
As a unique functionality, the EL860 CSE provides an adaptive traffic shaping engine, which makes it the first choice for shaping the traffic of networks where the throughput of the link is varying over time– as it is the case in DVB-S2 Adaptive Coding and Modulation (ACM) networks.
The EL860 encapsulates the shaped IP traffic in DVB-S2 Base-Band Frames that are ready to be processed by an external DVB-S2 modulator such as the EL170 or EL178.
With its embedded FlexACM controller, the EL860 monitors the signal reception conditions at the FlexACM-enabled remote sites of the network and selects dynamically and automatically the most effi cient modulation and coding parameters for each Base Band Frame. The bandwidth of the satellite link managed by the EL860 is therefore always utilized in the most effi cient manner while the traffi c shaping engine automatically adapts on-the-fl y to the resulting bandwidth variations.
Alternatively, the EL860 can be used in VCM (Variable Coding and Modulation) networks, where different modulation parameters are selected for each destination in a fixed manner. The adaptive traffic shaping of the EL860 will allow a dynamic distribution of the total bandwidth among the remote sites.
The EL860 ACM also supports simpler DVB-S2 modulation modes like CCM (Constant Coding and Modulation), were all data frames are modulated with the same fixed parameters.
For further improvement of the users’ download and web surfing performance the EL860 can be combined with the EL840 PEP-Box® performance enhancer appliance, which delivers a superior set of TCP and application acceleration as well as compression techniques.
