Comtech Memotec HX-5020C IP Traffic Load Balancing Platform

HX-5020C IP Traffic Load Balancing Platform

The Comtech Memotec HX-5020C IP Load Balancer is designed to operate on high capacity links such as backhaul trunks, and supports thousands of IP flows. It can also operate with N+1 (or N+p) WAN link redundancy. Traffic from the failed link will be redirected on the other remaining operational links. Flows are balanced using IP address(*) and optionally port numbers information to ensure packet flow remain together and continue on existing paths, while providing a good efficiency of the load balancer across the different links for backhaul applications. For the few flows that do not have an IP address (for example, Ethernet ARP request), the HX uses then the Ethernet MAC address to perform the load balancing. In order to maximize the load balancing accuracy and throughput of each individual links, the load balancer monitors each link and takes into account the actual real-time load of each link, allocating new flows based on the link with the maximum capacity available. That information is directly collected from the modems, therefore taking into account the effect of ACM on each individual link (critical when operating in Ka or Ku band, which is commonly the case of HTS satellites).

Key Features

• Enable to scale satellite links in order to match the capacity requirement of high throughput / high capacity backhaul links 
• Compliant operation with PEP appliances providing acceleration and other flow base processing functions 
• Can be integrated with Comtech’s WANOp solution in one single appliance 
• 100% Layer2-Layer3 Transparent (“Wire-like” operation) 
• Jumbo frames and multiple Layer 2 stacks support (VLANs, MPLS, L2 & L3 VPNs) 
• Dual stack IPv4 and IPv6 support 
• Real-time dynamic traffic shaping with ACM enabled Comtech EF DATA modems 
• Plug&play operation – minimal configuration, and no layer 3 IP routing information required 
• High Availability platform (power supply redundancy, 1+1 system redundancy, path redundancy)

Compatible with Advanced VSAT Solutions

The Memotec HX Series products can be added to an Advanced VSAT Solutions network for WAN optimization and application acceleration. The results can be significant improvements in user experience and a reduction by 20-80% in required bandwidth for TCP traffic.
