Traffic Shaping and TCP Optimization

Viewtify
Why QoS and Traffic Shaping Matter

Critical applications require consistent bandwidth to operate effectively. Relying solely on firewalls for North-South communications can lead to complex rule sets and diminished performance. Implementing a dedicated QoS device like Viewtify allows for more granular policy application in both communication directions. For East-West communications, Viewtify provides internal visibility, preventing bottlenecks and efficiently managing WAN traffic across branches.

Detailed Traffic Classification
Deep Packet Inspection

Effective network control begins with accurate traffic classification. Viewtify enables the creation of classification rules based on various parameters, including:

  • protocol
  • port
  • IP address
  • application
  • VLAN
  • subnet
  • time

 

This ensures precise traffic management tailored to organizational needs 

Comprehensive Network Control
Granular Profiles

Viewtify’s dedicated QoS appliance offers the flexibility to define diverse rules applicable to inbound, outbound, or bidirectional traffic. These rules encompass

  • minimum rate (total)
  • minium rate (%)
  • maximum rate (total)
  • maximum rate (%)
  • priority queues
  • drop policies
  • standard QoS settings

This provides complete control over network traffic.​

Traffic Shaping
Intuitive Multi-level Policy Configuration

Streamline your network traffic control with Viewtify’s intuitive tree-based QoS policy editor. Its user-friendly interface enables quick navigation, effortless creation of child policies, drag-and-drop organization, and reusable templates — all without limits on policy depth. This flexibility empowers organizations to build highly customized QoS hierarchies that match their exact needs.

Viewtify also includes a powerful real-time policy search and simulation tool. Instantly check where any IP address or application is being classified within your policies. This smart feature helps ensure precise traffic control and simplifies troubleshooting, significantly improving overall network management efficiency.

Traffic and Policies Analytics
Rich Set of Out-of-the-box Dashboards

Having accurate network metadata is just the beginning—how you visualize and analyze it makes all the difference.

Viewtify streams all traffic data to Viewtisight, our advanced analytics platform that delivers real-time, interactive dashboards along with powerful capabilities such as:

  • Static and dynamic alerts with anomaly detection

  • High data retention

  • Automated scheduled customized reports

  • Drill-down and filtering capabilities

  • Extensive report types and fully customizable dashboards

  • Correlation with other data sources via Viewtilog: SNMP, NetFlow, Syslog, CDRs, and more

Uncover insights, detect anomalies, and take action—all in one unified interface.

TCP Optimization
Why is it important?

TCP is fundamental to most internet services but can become a bottleneck under suboptimal network conditions such as packet loss, high latency, jitter, or wireless links. Viewtify’s TCP optimization enhances speed by over 100%, particularly in wireless environments, significantly improving network performance.

Unlike solutions that require deployment at multiple sites, Viewtify’s TCP optimization operates effectively with a single device at the central site. By enhancing rather than altering the TCP protocol, it maintains compatibility with encrypted traffic like HTTPS, offering a cost-effective solution for improving internet application performance.​

Viewtify’s TCP optimization employs a transparent proxy mechanism, reducing the time required to receive acknowledgments from communication destinations. This feature is particularly beneficial for service providers, Wireless Internet Service Providers (WISPs), and organizations with centralized internet exits, enhancing data transmission efficiency.

TCP Optimization
Enhanced TCP Stack Performance

Utilizing advanced algorithms, Viewtify’s TCP optimization detects congestion, allowing for more aggressive data transmission when the network is uncongested and appropriate back-off during actual congestion. This approach minimizes the impact of long round-trip times, accelerates recovery from packet loss, and reduces dropped connections, collectively improving user experience.


The effectiveness of Viewtify’s optimization varies based on network quality, wireless connectivity, and content characteristics. Generally, users experience performance improvements ranging from 30% to 150%, with some scenarios exceeding 200%, highlighting Viewtify’s capability to significantly enhance network efficiency.​

Bypass Module
Uninterrupted Network Connectivity

Viewtify deployment is inline, so Viewtinet supplies a passive bypass module for avoiding to have a new point of failure.

  • Failsafe protection: when power fails, the optical-relays ensure that the network flow continues uninterrupted.
  • Heartbeat protection: In the event of an appliance malfunction it bypasses the traffic intended for the Viewtify to the network ports, allowing it to continue to flow.
  • High density and flexibility: the bypass has 4 modules, each module can 2 links of fiber or copper interfaces.

Transparent Deployment
All-in-one architecture

Viewtify appliances are purpose-built to deliver a complete network optimization solution within a single, unified device. Each appliance combines advanced traffic management, customizable QoS policy configuration, and deep visibility through Viewtisight’s integrated reporting engine — all in one compact platform. This unified approach simplifies deployment, reduces hardware footprint, and accelerates time-to-value for IT and network teams.

To ensure seamless operation, the Viewtify bypass module is deployed physically inline with the network. Its role is to automatically direct traffic to the Viewtinet appliance for processing, without interrupting the normal flow of packets. In case of failure or maintenance, the bypass guarantees uninterrupted connectivity by allowing traffic to pass through uninspected — acting as a failsafe layer of protection.

Importantly, the bypass and monitoring interfaces are designed without IP addresses, making the entire deployment completely transparent to the existing network infrastructure. This stealth deployment ensures no disruption to IP routing, no changes to the current topology, and no additional configuration burden for network administrators. Whether it’s for a data center, enterprise WAN, or branch office, Viewtify integrates smoothly into any environment with minimal impact.
