  • Superior TCP acceleration
  • Traffic classification and policing
  • out-of-the-box solution
  • Server redundancy and load-sharing


System Architecture
  • Distributed Performance Enhancing Proxy (dPEP) architecture (RFC 3135)
  • Acting a dPEP server in a point-to-point or star network
  • Based on IP tunneling technology
  • Operates in L3 routing mode (in-path or on-a-stick)
  • Supports asymmetric routing between the EL840 Server and the EL810, EL820 and EL830 Client appliances
  • Linux OS based
  • Built-in CPU watchdog and RAM-usage monitoring
  • Supports built-in redundancy and load sharing

Monitoring Only
  • 1 x serial
  • 2 x PS/2 for keyboard/mouse
  • 4 x USB e.g. for keyboard/mouse
  • 1 x VGA
2 x LAN auto switching 10/100/1000 Base-T Ethernet interface, RJ-45
1 x additional LAN (optional)
  • SSH Access
  • Web based GUI
Authentication and Accounting
  • Server side enforced access control through gateway authentication
  • Forward and return channel traffic accounting
TCP Acceleration
  • Used transport protocol: ETCP (Enhanced Transmission Control Protocol)
  • Fills the available data pipe up to the configured maximum throughput
  • Control traffic reduction through session multiplexing and combined NACK/ ACK technology (compared to SCPS-TP average bandwidth utilization savings: 80 - 95 % of volume and packets on return channel)
  • Packet loss and delay based three-tier congestion control technology
  • SYN ACK spoofing for HTTP traffi c
  • Dynamic RTT based window size adaptations
  • Fast start algorithm
  • Packet aggregation
  • Configurable MTU
  • Tolerates dynamically changing network conditions, packet loss, packet reordering and large data queues
Data Compression
  • Supports on-the-fly TCP payload compression
  • Average compression savings: 25 - 40 %
  • Deflate compression algorithm (RFC 1951)
  • Selective compression based on URL extension and/or MIME type
VPN Support and Security (Optional)
  • Transparent interception of traffic
  • On-the-fly Blowfi sh encryption
  • Available key length: 56 bits (default) up to 448 bits (optional)
  • Hides original end-point information (IP, port, etc.)
  • Automatic encryption key negotiating according to Diffie-Hellman algorithm (RFC 2631)
  • Re-keying on basis of ETCP sessions
Application Acceleration (Optional)
  • Server-to-gateway HTTP prefetching with support for embedded HTML
  • Server-side JavaScript and CSS objects prefetching
  • SMB (CIFS) read-ahead technology
  • POP3 e-mail prefetching
Traffic Policing (Optional)
  • Real-time adaptable traffic policy changes without service interruption and without packet dropping
  • Three-tier rule support, 600 shaping rules configurable
  • Shaping IPv4 unicast and multicast traffic
  • Supports Peak Information Rate (PIR) policies and equal or weighted bandwidth distribution
  • Up to ten configurable traffic priority classes
  • Bandwidth is distributed equally or according to a configured weighting factor
  • Supports IP ToS (Type of Service) transparency or IP ToS injection, classification and shaping of accelerated and encrypted ETCP traffic
Traffic Classification (Optional)
  • Source and/or destination IP address, IP address range or IP subnet
  • Protocol type (TCP, UDP, ICMP, RTP, ESP, AH, GRE, ETCP)
  • Source/destination port or port range (TCP or UDP)
  • IPv4 ToS values
ACM Support (optional)
Supports build-in ACM controller of EL170, EL178, EL470 and EL478
Client Side Component
  • EL810 Mobile PEP-Box® Terminal or
  • EL820 PEP-Box® Terminal or
  • EL830 PEP-Box® Gateway or
  • TL100 TelliNet Client software (installed on third party communication devices)
