At Cnergee, we are dedicated to pushing the boundaries of network technology. Our Packet-based Multi-session Tunnel Aggregation (PMTA) is a patented, in-house developed technology that revolutionizes how data is transmitted across Wide Area Networks (WANs).
PMTA is not just another networking feature; it’s a complete rethinking of how to optimize performance, security, and reliability. PMTA establishes multiple sessions between multiple SD-WAN links of the Concentrator (hub) and CPE (spoke). It enhances network performance and security through a unique approach to data transmission.
How PMTA Works
PMTA is designed with the understanding that networks are variable and dynamic. Traditional routing protocols are often vulnerable and complex. Here’s how PMTA works to overcome these limitations:
● Packet Segmentation: PMTA breaks down each packet into smaller bits, encrypts these segments, and transports them through multiple sessions using link aggregation.
● Dynamic Adaptation: PMTA dynamically adapts to network conditions, eliminating the complexity associated with traditional dynamic routing protocols. This allows our solution to react to changes in network conditions in real-time, which maximizes the efficiency of data transfer.
● Multiple Sessions, Single Tunnel: PMTA creates multiple sessions within a single tunnel, utilizing aggregated hybrid WAN links, resulting in optimized bandwidth usage and performance.
Advantages of PMTA
PMTA offers several key advantages over traditional SD-WAN solutions:
● True WAN Aggregation: Unlike conventional load balancing methods that only use one WAN link at a time, PMTA uses all available paths simultaneously for each application, maximizing bandwidth and throughput.
● Enhanced Application Performance: PMTA reduces latency and improves application performance, making it ideal for real-time applications like video conferencing and VoIP .
● High Security: Each packet segment is encrypted with 256AES encryption, and keys are rotated every 10 minutes, providing a resilient defense against brute force and quantum computer-based attacks.
● Resilience: PMTA maintains configured Quality of Service (QoS) profiles during failovers, ensuring that critical applications continue to perform optimally.
Simplified Management: PMTA uses a single IP address for all sessions, simplifying network management and reducing configuration complexity.
● Jitter Reduction: By distributing traffic across multiple sessions, PMTA reduces jitter, which significantly enhances the quality of voice and video communication.
● Predictable Performance: PMTA offers consistent performance due to its fixed single-path approach, making it suitable for applications that require stability and consistent latency.
Addressing the Flaws of Traditional SD-WAN
Traditional session-based SD-WAN platforms are based on assumptions that aren’t always true:
● Abundant bandwidth
● Consistent circuit availability
● Predictable network conditions
These assumptions often lead to:
● The need for additional technologies like FEC (Forward Error Correction) to compensate for packet loss.
● Poor performance in shared or over-provisioned networks.
● Increased congestion and bandwidth consumption due to reliance on FEC.
PMTA is designed to address these flaws:
● Avoids FEC: By focusing on efficient packet transmission, PMTA eliminates the need for FEC.
● Optimized for Shared Networks: PMTA is ideal for shared and over-provisioned networks because it dynamically adapts to network conditions.
Advanced Security Features of PMTA
In addition to its performance benefits, PMTA offers advanced security measures:
● Packet Deduplication: By removing duplicate packets, PMTA reduces the risk of data corruption or loss caused by network errors.
● Packet Reordering: By rearranging packets that arrive out of order, PMTA ensures efficient and reliable data transmission.
● Session-wise AES Encryption with Key Lifetime: Data is encrypted per session with AES, and keys are rotated regularly, further enhancing security. Cnergee’s PMTA technology represents a leap forward in SD-WAN solutions. It provides superior performance, security, and reliability, making it a powerful tool for businesses that rely on robust network infrastructure.
