EL840 PEP-Box Server
The Newtec EL840 PEP-Box® Server is a Performance Enhancing Proxy (PEP) appliance that combines a number of advanced traffic enhancement and shaping functionalities for the server side of point-to-point and point-to-multipoint satellite IP network. The EL840 combines a number of advanced traffic enhancement and shaping functionalities for the server side of point-to-point and point-to-multipoint satellite IP network, such as IP trunking networks. The EL840 PEP-Box® Server is to be used in conjunction with the EL810 Mobile PEP-Box® Terminal, the EL820 PEP-Box® Terminal or the EL830 PEP-Box® Gateway. Alternatively, the EL840 can also be used with the TL100 TelliNet Client software installed on third party communication devices.
TCP and HTTP, the most widely used protocols in the Internet, show very poor performance when being used over high latency and/or lossy networks, such as satellite networks. As a result users experience slow download speed and surfi ng performance. Moreover valuable satellite capacity is not used in the most efficient way.
The ideal solution to overcome such drawbacks is the PEP-Box® Server EL840. The EL840 integrates a traffic enhancement technology that accelerates any TCP based transmissions over high latency networks. At the same time the EL840 Server greatly reduces the TCP data traffic on both forward and return link by means of data compression as well as TCP packet aggregation and session multiplexing. This is achieved by using ETCP (Enhanced TCP) instead of TCP over the satellite link.
The EL840 PEP Box can be used in conjunction with the EL860 VCM/ACM shaper and encapsulator, in networks where the transmission bandwidth is varying dynamically. Thanks to the Cross Layer Optimization capability, the EL840 dynamically adjust its performance according to the changing bandwidth availability. As a result, zero packet loss transmission can be ensured.
The EL840 PEP-Box® Server comes with two additional option packages: A first option package is called Advanced and performs the acceleration of popular protocols such as HTTP, FTP, POP3 and SMB (SMB). The HTTP prefetching technology enhances the web surfing experience to an extent that the download time for a web site can be reduced by more than 70 %, so the user has the impression of surfing via regular DSL or Cable based Internet connections. On top of that, the Advanced option package of the EL840 PEP-Box® Server can secure any data traffic exchanged via the network by building up an encrypted VPN between the hub and the remote sites.
The second option package is called Premium and regroups all the features of the default and Advanced versions in addition to a network policing engine. This engine allows the distribution of the overall available bandwidth among services and end-users according to confi gurable criteria, e.g. prioritization of VoIP traffi c. The Premium version of the EL840 PEP-Box® Server can also be used in networks where the transmission bandwidth is varying, such as DVB-S2 Adaptive Coding and Modulation (ACM) networks. With the Premium option, the EL840 can monitor the modulator (e.g. EL178) and adjust its shaping behavior according to the changing bandwidth availability. As a result zero-packet-loss transmission can be ensured.
A single EL840 appliance supports up to 20 Mbit/s of throughput. For automated fail-over and higher rates, multiple EL840 can be operated in load sharing mode.
The Elevation PEP-Box® appliances are based on the TelliNet and TelliShape of the Tellitec® IP software product family.
