Free QoE module

Free trial version

Save up to 25% of the bandwidth capacity by prioritizing traffic

Step 1: analyze

Analyze your network with the QoE option. Estimate network load by traffic type and peak load time.

Step 2: prioritize

Classify the traffic on the basis of used protocol with the FastQoS option. Label the services you agree to limit during peak hours, for example, torrents and updates, to be of the lowest priority. Webcasts, web traffic, games, and IP-telephony belong to a higher priority class.

Based on priority classes, the DPI limits the speed of traffic when the inbound traffic approaches the threshold value.

Result

Saves up to 25% uplink capacity and improves service quality during peak hours.

Take care about your subscribers with smart ACL

Step 1: do not limit, control

  • Do not block your subscribers when they run out of money. Allow them to pay debts through available payment systems.
  • Give your subscribers an opportunity to log into public Wi-Fi networks via portal, SMS or Call ID.

Step 2: use the Captive Portal option

Traditional network Access Control Lists (ACL) define service ports or domain names on L3 devices, the services of which can or cannot be accessed. Vas Experts DPI controls traffic up to L7. Meaning that you can restrict or allow access to specific services, applications and websites for certain users or groups of users.

Result

Subscribers will not leave you when they run out of funds, users of public Wi-Fi networks may become your clients, and the load on your tech support will go down.

Secure your subscribers from illegal content

Step 1: choose the connection option

  • In-line: at L2 of the OSI model, between the edge router and the subscriber termination y gateway (BRAS)
  • Mirroring: work with a traffic copy through SPAN ports or optical splitters
  • Asymmetric scheme: only for filtering web traffic based on policy-based routing

Step 2: use different tools

  • Filtering by operator’s list
  • Filtering by URL with non-Latin characters
  • Filtering traffic from proxies and mobile devices
  • Blocking HTTPS traffic on the basis of SSL Common Name and Server Name Indication (SNI)
  • Blocking traffic at nonstandard ports
  • Filtering by specific users
  • Redirecting to the parked page

Result

Illegal traffic blocked 100%.

Time to go for IPv6 with CG-NAT

Step 1: isn’t it time?

There are not enough IPv4 addresses today—people use more than 4.3 billion devices. Time to go for IPv6.

Step 2: carrier-grade NAT

Use the CG-NAT option of the Vas Experts DPI platform as part of a seamless migration strategy to IPv6 and support for Dual Stack. NAT will work simultaneously for IPv4 and IPv6. CG-NAT provides:

  • Full RFC 6888 and RFC 4787 compliance
  • provides transparent operation of P2P protocols (torrents, games)
  • allows to limit the number of TCP and UDP ports for the subscriber (DDoS protection)
  • supports functions of Hairpinning, Paired IP address pooling and Full Cone
  • NAT logging can be exported via IPFIX protocol (NetFlow v10)

Result

No more costs for IPv4 addresses. You will also ensure extra network security without loss of service quality.

Innovate your network with DPI-based BRAS

Step 1: control access

The main task of BRAS service gateway is to authorize subscribers and apply billing plans to them. Registering the first subscriber’s package, BRAS generates a request to the billing system through the Radius server and learns about subscriber’s services. The function works in L3 (IPoE) and L2 (DHCP, PPPoE, ARP) modes.

Step 2: give your network new possibilities

  • Providing Quality of Service (QoS) within the billing plan
  • Controlling Internet access of your subscribers
  • Applying billing plan policies
  • Interacting with the Radius server
  • IPoE, PPPoE authorization
  • Assigning additional billing options
  • Redirecting to Captive Portal
  • Operating on L2 and L3
  • Dual Stack IPv6 / IPv4, Radius CoA support
  • Multi-users: one login is connected with multiple IPs
  • Supporting domain’s whitelists, regardless of IP address
  • Increasing speed for local resources or P2P networks

Step 3: full implementation support

Increase ARPU with no extra costs

Step 1: use extra income tools

  • When a subscriber visits a specific HTTP page, they will be redirected to a special landing page with your offer. The redirection policy can be configured through a convenient graphical interface or CLI.
  • An option to replace or block advertising content. Allows you to selectively change the content of HTTP pages with banner ads, and control subscriber access to the service.

Step 2: maximize advantages

Possible use cases:

  • Monetizing free Wi-Fi access points
  • Social billing plans
  • Providing ad blocking service
  • Replacing third-party banner ads with your own ad

Result

  • Creating an additional subscriber communication channel
  • Polling, notification on service interruptions, payment reminders
  • Increasing income per subscriber due to native ads without making subscribers uncomfortable

Protect your network with Mini-Firewall & Anti-DDoS

Step 1: arm yourself

Use the Mini-Firewall option

  • To prevent hacking users through open system ports
  • To block malicious behavior from subscribers

Use the Anti-DDoS option

  • To protect subscribers from TCP SYN flood
  • To protect subscribers from Fragmented UDP flood
  • To stop a DDoS attack with CAPTCHA

Step 2: simply turn it on

Vas Experts DPI is equipped with a high-performance mechanism against TCP SYN flood and Fragmented UDP flood attacks. The module can process up to 20 million packages per second. The Turing test (CAPTCHA) is used to protect against DDoS. The Mini-Firewall option ensures extra security.

Result

Comfort and safety for your subscribers without the need to purchase additional equipment.

Get to know your subscriber and improve Quality of Experience

Step 1: who is who

Use the Quality of Experience (QoE) option to classify your subscribers, solve their problems and find additional opportunities.

QoE is a software product for collecting statistics and assessing the quality of experience.

Step 2: use QoE for different tasks

  • When setting up the connection, the DPI exports information on delays and losses between the client and the DPI, as well as between the DPI and the host. Round Trip Time (RTT) and TCP Retransmits values help you identify and solve network problems.
  • Fighting resale traffic. The DPI exports unique User-Agent data which is transmitted in the HTTP request. The QoE module aggregates data for each IP (login). For statistical purposes, the subscriber’s NAT includes each device. One household usually has up to 20 unique User-Agents. A bigger number indicates a possible contract violation.
  • Fighting outflow. The DPI exports ClickStream—all HTTP / HTTPS user requests. QoE aggregates data for each IP (login). If your subscriber often visits competing websites, the QoE module will notify you on this, helping you retain the client.
  • Search for Smart TV. The QoE module shows all Smart TV devices, that your subscribers have. You can offer subscribers your own OTT service.

Result

A free QoE Lite option will help you find out who your subscribers are and offer them what they really need.

How FastDPI looks inside

 

Available Options


Quality of Service (QoS)

The Quality of Service (QoS) module enables bandwidth management based on application layer protocols, data flows and bandwidth usage. It saves up to 25% of the bandwidth capacity by prioritizing traffic, which improves the operator’s quality of service in general.

Quality of Experience (QoE)

Quality of Experience (QoE) is a DPI module that gathers statistics and evaluates QoE. The data that it collects are compared with the preset metrics to evaluate the quality of telecom services and Internet connection for a single user. Based on this information, the module initiates steps required to improve the quality of service.

Access Control Lists (ACL)

Access Control List (ACL) is an option in VAS Experts DPI designed to create intelligent access control lists, unlike the standard ACLs. Such ACLs control and manage traffic at higher layers of the OSI model by limiting or allowing access to services, applications and resources. You have control over both—single users and user groups.

CG-NAT

The CG-NAT option enables network address and port translation and provision of a single public IPv4 address to several users. CG-NAT is introduced to deal with IPv4 address exhaustion and simplify transition to IPv6.

The “classic” NAT with port translation on Linux or FreeBSD is a port-restricted NAT that allows inbound connections only on a specific port. As a result, for example, two gaming consoles behind such a NAT gateway won’t be able to communicate with each other, because the port number will be changed. Similarly, it prevents the connection of torrent trackers and other peer-to-peer protocols. CG-NAT addresses these issues by allowing inbound connections on any port.

Example of VAS Experts DPI being used as a NAT gateway with redundancy:

Firewall and Anti-DDoS

VAS Experts DPI comes with a firewall that protects users from being hacked on open ports and blocks any illegal subscriber activity. The firewall protects your network from DoS and malware attacks, improves the quality of service, ensures reliable and secure operations. You can use the firewall together with the QoE module to reveal the perpetrator and the victim and quickly notify users about any suspicious activity.

Marketing and Redirecting

With Marketing and Redirecting, operators receive a tool to notify subscribers about new offers or future network maintenance. When an operator activates the service, instead of being redirected to the home page, the subscriber is redirected to the operator’s information page, which contains all the necessary data.
