Service Gateway Engine

Due to the flexibility of Eco-solutions, on the basis of one platform, you can get not one, but several functionalities at once:

• CG-NAT logging through Syslog and Netflow v9;
• BRAS — Services Gateway for limitation the access speed to subscribers, disconnecting non-payers with redirecting to the portal (“time to pay” page);
• URL Filtering — filtering subscribers according to the prohibited list, the provision of “children’s Internet” services;
• The EcoDPI solution is designed to analyze packages at the levels up to the application layer (Layer 7) of the OSI model. EcoDPI is able detects traffic from more than 3,000 different applications;
• Quality of Experience — collection of statistics that measure the quality of perception (Quality of Experience, QoE), compiles various metrics for further analysis of user experience and flexible management of the quality of the services provided.

You can purchase any set of functions, for example, CG-NAT + BRAS.

The solution is certified (CCC) and is intended for use on networks of telecom operators and broadband access providers.

All platforms are running at “wire speed” — for packets with an average length of 480 bytes or more.

The EcoSGE solution processes untagged frames and frames with one or two 802.1Q tags.
All 10G ports for subscriber traffic are divided pairs: Inside (LAN) and Outside (WAN). Each pair of LAN + WAN ports is a pseudo-wire: packets arriving on LAN-1 are transmitted to WAN-1, packets arriving on WAN-3 are transmitted to LAN-3 and so on. Packet transfer between different pairs does not occur. Moreover, all data structures — a table of broadcasts, sessions, etc. — are common to the entire device.

Since the device is a bridge, it is connected between two routers (PE and Core) or between two VRFs of the same router.

All or several LAN ports can be combined in a LAG (based on LACP) on the router, similarly for WAN ports. EcoNATDPI transparently passes ARP frames, IP-Multicast, LACP service traffic, and other Ethernet frames into which IP packets are not encapsulated.

The universal EcoSGE platform meets all the requirements for the implementation of the Accessible Internet project (zero-rating), which requires telecom operators to provide free access to socially significant domestic Internet services.

A typical scheme for including EcoSGE in the operator’s network:

Most common EcoSGE installation location is in front of the edge router. However, the EcoSGE connection scheme may differ from the typical one depending on the characteristics of the customer’s network.
