Advantages and basic features
The throughput of EcoBRAS solution reaches 160 Gbps per unit, surpassing foreign analogues. The device can serve up to 250 thousand simultaneously active subscribers, for whom the rules of connection speed limitation in both directions are established.
The EcoNAT device is transparent to all types of service traffic, including routing protocols: BGP, OSPF, ISIS, STP, LACP, BFD.
EcoBRAS implements a modern approach for connecting IP over Ethernet (IPoE) subscribers. The absence of additional encapsulation (PPTP, PPPoE and others) allows you to increase the reliability of the system, simplify the processing of subscriber traffic and debugging.
The speed limit of traffic to the subscriber is carried out in both directions, independently, in increments of 64 Kbps.
It is possible to create an “Open Garden” with a list of networks available to disconnected subscribers: DNS servers; sites of the company, payment systems, banks and so on.
Assigning services to individual subscribers
To limit the speed of data reception and transmission or redirection to the portal and to charge up a subscriber’s account in EcoBRAS, a system of configurable policies and related services is used, which are a set of actions performed if the source address or session destination falls into the specified ACL. The usual functionality of EcoBRAS involves setting the Access Control List (ACL) of levels 3 and 4 as policies that define the traffic for which the rules of this service are applied. The following operations can be performed as actions: “skip” (with a speed limit), “block”, and “redirect to a given URL”. Using EcoBRAS with URL filtering functions (EcoFilter) also allows you to specify URL lists (white or black) as policies. Up to six services can be simultaneously active for each subscriber, statically defined or dynamically received using the RADIUS protocol. If a subscriber needs to change the set of services or their parameters, this can be done using the RADIUS Change of Authorization (CoA) function.
Integration with billing system
When connected, the IP address and MAC address of the subscriber can be identified using the RADIUS protocol. For unknown subscribers, it is possible to provide a portal redirection service for identification by third-party methods (for example, using SMS). In accordance with the subscriber’s profile, he is assigned a set of services, for each of which the amount of data transmitted and received is taken into account and is transmitted to the billing system in RADIUS Accounting messages. Moreover, the device supports a proprietary protocol for interacting with any billing system (protocol description is available on request). The protocol is based on the PUSH method: the billing system periodically connects to BRAS via TCP and gives a series of text commands. Billing regularly send requests which contracts are entered into on the device and adds missing ones or removes unnecessary ones. At the same time, it is possible to manage a set of subscriber services in real time (as in case with CoA RADIUS), including using several billing systems at the same time. The manufacturer provides services for the integration with any billing system with EcoBRAS using both the open API and the RADIUS protocol.
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.
