The ViBE Platform
Built Different. By Design.
ViBE isn't a software overlay on broken protocols. It's a purpose-built networking platform that replaces TCP across the WAN, delivering performance that conventional approaches can never achieve.
Engineered from First Principles
Most SD-WAN platforms begin with the same flawed assumption: that TCP/IP is a given, and the job of the overlay is to make the best of a bad situation. ViBE was designed with a fundamentally different philosophy. Rather than accepting the limitations of a protocol designed in the 1970s for a world of text terminals and batch transfers, ViBE was engineered from the ground up as a complete replacement for TCP across the wide area network. Every component — from QoS to encryption to failover — was purpose-built to work together as a cohesive system, not bolted on as an afterthought.
The key architectural insight is that TCP's problems are not bugs to be patched — they are fundamental design constraints that cannot be overcome by any amount of clever software layered on top. TCP's slow-start algorithm, its window-based flow control, its inability to distinguish between congestion loss and random loss — these are not edge cases. They are the protocol working exactly as designed, in a world that has moved far beyond its original assumptions. ViBE eliminates these constraints entirely by replacing TCP for the WAN portion of every connection, using a proprietary protocol specifically designed for real-time, multi-application, multi-path networking.
Critically, this replacement is completely transparent to endpoints. Clients and servers continue to speak standard TCP — they have no idea that ViBE exists. The CPE device at each site acts as a transparent proxy, terminating TCP connections locally (within sub-millisecond latency) and transporting the data across the WAN using ViBE's proprietary protocol. On the far side, the data exits as standard TCP once again. No client software, no application changes, no driver installations. Every device on the network — from IP phones to POS terminals to laptops — benefits automatically from the moment ViBE is deployed.
Byte-Level Quality of Service
Traditional QoS operates at the packet level. When a voice packet and a data packet compete for the same bandwidth, the system must choose one — and the loser waits. The problem is that packets are blunt instruments. A single data packet might be 1,500 bytes, while a voice packet is just 60 bytes. By reserving bandwidth at the packet level, traditional systems must allocate capacity in large, wasteful chunks. The result is that 20–30% of total available bandwidth is consumed by QoS overhead alone — bandwidth you've paid for but can never use for actual traffic.
ViBE's byte-level QoS operates on a fundamentally different principle. Instead of managing whole packets, ViBE manages the individual bytes within its proprietary tunnel. When a high-priority voice byte needs to be sent, it is inserted into the stream immediately — even if that means interrupting a data transfer mid-packet. The data transfer resumes seamlessly once the voice byte has been dispatched. This means voice traffic receives absolute, unconditional priority without reserving a single byte of bandwidth that isn't actively being used. Every byte of your connection is available for productive traffic, 100% of the time.
The practical impact extends far beyond voice quality. Because byte-level QoS eliminates the need for bandwidth reservation, interactive protocols like POS transactions and SSH sessions remain perfectly responsive even when the link is under heavy load. A user downloading a large file will never notice a POS transaction completing in the background, and the POS terminal will never notice the download. Both operate as if they have the link to themselves — because at the byte level, they effectively do.
TCP Acceleration
TCP was designed in the 1970s with a conservative assumption: if a packet is lost, the network must be congested, so the sender should slow down. This made sense on the early internet, where packet loss almost always meant congestion. On modern networks — especially those involving wireless, satellite, or any real-world internet path — packet loss is routine and rarely indicates actual congestion. Yet TCP still reacts the same way: it halves its sending rate, then slowly ramps back up through its "slow-start" algorithm. At just 1% packet loss, this behaviour can reduce TCP throughput by over 90%. On a satellite link with 500ms of latency, TCP's window-scaling limitations mean you may never reach full line rate at all, regardless of how much bandwidth is available.
ViBE solves this with a transparent TCP proxy architecture. When a client device initiates a TCP connection, it is terminated at the local CPE within sub-millisecond latency — the client believes it has an incredibly fast, loss-free connection to its destination. The CPE then transports the data across the WAN using ViBE's proprietary protocol, which is immune to TCP's slow-start, congestion collapse, and window-scaling problems. On the remote side, the data exits as a standard TCP connection to the destination server. The entire process is invisible to both endpoints.
The performance difference is not incremental — it is transformational. Independent testing by Broadband-Testing demonstrated that ViBE delivers 25 times the throughput of standard TCP under 1% packet loss conditions. On high-latency satellite links with 500ms round-trip time, ViBE achieves 7 times standard TCP throughput. There is no ramp-up period, no slow-start penalty, and no congestion collapse. Every connection operates at full speed from the very first packet, regardless of the underlying link conditions.
RAIN Mode — Redundant Array of Inexpensive Networks
The concept behind RAIN is elegantly simple: if you send the same packet across multiple independent network paths simultaneously, the probability that all copies are lost drops exponentially. ViBE's RAIN mode duplicates every packet across two or more connections — fibre, DSL, cellular, satellite, or any combination. The receiving CPE accepts whichever copy arrives first and discards the duplicates. The result is millisecond-level failover that is completely invisible to users. There are no dropped calls, no broken TCP sessions, no reconnection delays. If one link fails entirely, traffic continues uninterrupted on the surviving path without a single packet being lost.
RAIN's benefits extend beyond simple failover. On a single link experiencing 10% random packet loss — a common scenario on congested or wireless networks — RAIN reduces effective loss to under 1% by providing an independent second chance for every lost packet. For networks experiencing bursty loss patterns (where packets are lost in clusters rather than randomly), ViBE offers a configurable delay parameter that staggers the duplicate packets by a specified number of milliseconds. This ensures that a burst of loss on one path doesn't coincide with the duplicate burst on the other, providing resilience against even the most challenging loss patterns.
The "Inexpensive Networks" in RAIN's name reflects a fundamental economic insight: two cheap, unreliable internet connections combined through RAIN will outperform a single expensive "guaranteed" leased line — at a fraction of the cost. Organisations can replace costly MPLS circuits with commodity broadband and cellular connections, achieving better reliability, better performance, and dramatically lower monthly costs. RAIN turns the economics of networking upside down, making redundancy accessible to organisations of every size.
Intelligent Bonding
Traditional link bonding is fragile. It typically requires matching link speeds, struggles with out-of-order packet delivery, and treats failover as an all-or-nothing event. ViBE's intelligent bonding takes a fundamentally different approach. Any combination of connections can be aggregated into a single high-performance pipe — a 100Mbps fibre line bonded with a 20Mbps DSL and a 5Mbps cellular connection works seamlessly. ViBE dynamically distributes traffic across all available links based on their real-time capacity, latency, and quality, ensuring that every link contributes its full potential without any efficiency loss from speed mismatches.
A critical differentiator is ViBE's elimination of out-of-order packet delivery — the Achilles' heel of most bonding solutions. When packets arrive out of sequence (inevitable when distributed across links with different latencies), TCP interprets this as packet loss and triggers its congestion control mechanisms, destroying performance. ViBE's proprietary protocol handles reordering within the tunnel itself, ensuring that packets are always delivered to the endpoint in the correct sequence. Applications see a single, perfectly ordered stream regardless of how many underlying links are in use.
Failover in ViBE's bonding is dynamic and unidirectional. If the upload quality on a cellular link degrades while download remains healthy, ViBE will stop sending upload traffic on that link while continuing to receive download traffic — maximising the use of every available resource. When link quality recovers, traffic is automatically restored without manual intervention. This continuous, granular monitoring means that a single large data stream can simultaneously utilise all bonded links at their full individual capacities, achieving aggregate throughput that no single connection could provide.
Header Optimisation
Every IP packet carries overhead: 20 bytes of IP header, 8 bytes of UDP header (or 20 bytes for TCP), plus any additional encapsulation layers. For large data transfers, this overhead is negligible — a few percent of total bandwidth at most. But for small-packet protocols like voice, the overhead is devastating. A G.729 voice codec produces just 20 bytes of audio payload per packet. By the time IP, UDP, and RTP headers are added, that 20-byte payload has ballooned to 60 bytes. Add Ethernet framing and the packet reaches 106 bytes on the wire. Over 80% of the bandwidth consumed by that voice call is pure overhead — headers, not audio.
ViBE's header optimisation eliminates this waste entirely within the tunnel. Because ViBE controls both ends of the connection, it can strip redundant headers from packets as they enter the tunnel and restore them perfectly on exit. The IP, UDP, and RTP headers for a voice stream don't change between packets (or change predictably), so there is no need to transmit them repeatedly. Inside the ViBE tunnel, only the essential payload — the actual audio data — is transported, along with a minimal ViBE header that allows reconstruction at the far end.
The bandwidth savings are dramatic. For G.729 voice calls, header optimisation can reduce per-call bandwidth consumption by over 60%, allowing the same link to carry substantially more simultaneous calls. Combined with byte-level QoS, this means that ViBE can support hundreds of concurrent voice calls on bandwidth where conventional approaches manage only dozens. The optimisation is applied transparently and automatically — no configuration is required, and endpoints are completely unaware that their headers have been compressed and restored.
AES-256 Encryption & Traffic Obfuscation
ViBE supports AES-256 encryption across all tunnel traffic, providing defence-grade protection for data in transit. Encryption is available by default but optional — organisations can choose to enable it based on their security requirements and performance trade-offs. When enabled, all traffic within the ViBE tunnel is encrypted end-to-end between CPE devices, ensuring that even if the underlying network is compromised, the data remains unreadable to any observer.
Beyond encryption, ViBE provides a layer of security that traditional VPNs cannot match: traffic obfuscation through multi-path splitting. When bonding is active, ViBE distributes traffic across multiple independent network paths, each potentially using different ISPs, different physical media, and different geographic routes. An attacker monitoring any single path sees only a fragment of the total data stream — a fragment that is already encrypted with AES-256. Reconstructing the complete communication would require simultaneously compromising every network path, a task that is practically impossible in any real-world scenario.
This combination of strong encryption and inherent traffic splitting makes ViBE particularly suited to defence, government, and high-security enterprise deployments. Unlike conventional VPN solutions that send all traffic through a single encrypted tunnel (creating a single point of monitoring), ViBE's architecture makes it fundamentally impossible for any single observer to capture the complete data flow. The security is not just a feature bolted on top — it is an inherent property of the platform's multi-path architecture.
EsP — Estimated Performance
Most network monitoring tools rely on synthetic measurements — periodic ping tests, scheduled speed tests, or SNMP polling intervals — to estimate link quality. These measurements tell you what the link could do in theory, not what it is doing right now. ViBE's EsP (Estimated Performance) engine takes a radically different approach: it derives real-time bandwidth estimates from the actual production traffic flowing through the tunnel. Every packet that traverses the ViBE link contributes to a continuously updated model of the link's true capacity, latency, and loss characteristics. There is no synthetic probing, no wasted bandwidth on test traffic, and no gap between measurement and reality.
EsP feeds directly into ViBE's QoS engine, enabling dynamic, real-time adjustment of traffic priorities based on actual available capacity. If a bonded link's bandwidth drops — due to congestion, a mobile connection moving between towers, or a shared connection being consumed by other users — EsP detects the change within milliseconds and adjusts the QoS parameters accordingly. Priority traffic is protected, best-effort traffic is gracefully throttled, and the transition is invisible to users. When capacity recovers, EsP detects that too, and traffic allocation is restored automatically.
This real-time feedback loop is what allows ViBE to handle congestion gracefully rather than catastrophically. Traditional systems discover congestion only after it has caused packet loss, retransmissions, and degraded user experience. EsP detects the early signs of congestion — subtle changes in inter-packet timing and acknowledgement patterns — and adjusts proactively, before users are affected. The result is a network that adapts continuously and smoothly to changing conditions, maintaining consistent application performance regardless of what is happening on the underlying links.
Deployment Orchestration
Deploying and managing a distributed SD-WAN fabric across dozens or hundreds of sites has traditionally been a complex, error-prone process requiring skilled engineers at every location. ViBE's centralised orchestration platform eliminates this complexity entirely. New CPE devices can be provisioned remotely from a single management console — the administrator defines the site's network topology, QoS policies, and security settings, and the system generates a complete, validated configuration that is pushed to the device automatically. Zero-touch provisioning means a non-technical person at the remote site simply connects the CPE to power and internet, and the device configures itself.
The orchestration platform provides comprehensive network management capabilities beyond simple provisioning. Firewall rules, DHCP configurations, VLAN assignments, and routing policies are all managed centrally and pushed to devices in real time. Configuration changes are validated before deployment, preventing the kind of misconfigurations that cause outages in manually managed networks. Auto-generated configurations ensure consistency across the entire deployment, eliminating the configuration drift that inevitably occurs when devices are managed individually.
For organisations with existing management infrastructure, ViBE's orchestration platform offers full API integration, allowing it to be incorporated into existing NOC workflows, ticketing systems, and automation pipelines. SNMP support provides compatibility with traditional network monitoring tools, while ViBE's own real-time statistics engine delivers granular, per-link, per-application visibility that goes far beyond what SNMP can provide. Every metric — bandwidth utilisation, packet loss, latency, jitter, QoS queue depths, EsP estimates — is available in real time through both the management console and the API.
Protocol Flexibility
ViBE's tunnel transport defaults to UDP for optimal performance, but the platform recognises that network environments vary enormously. Some corporate firewalls block UDP traffic. Some ISPs throttle or shape non-TCP protocols. Some satellite providers only reliably pass ICMP. ViBE adapts to all of these scenarios by supporting multiple tunnel transport protocols — UDP, TCP, and even ICMP — configurable per link and per direction. If UDP is blocked on a particular path, ViBE can encapsulate its tunnel within TCP, passing through even the most restrictive firewalls while still providing its full suite of acceleration and QoS capabilities inside the tunnel.
NAT traversal is handled automatically, allowing ViBE CPE devices to operate behind any NAT configuration without manual port forwarding or firewall rules. The platform supports full Layer 2 transparency, including VLAN tagging, enabling it to bridge remote LANs as if they were directly connected. This Layer 2 capability is essential for applications that rely on broadcast traffic, multicast, or non-IP protocols — scenarios where Layer 3 SD-WAN solutions fail entirely.
ViBE runs on standard Linux, which means it can be deployed on virtually any hardware platform — dedicated appliances, commodity x86 servers, virtual machines, or cloud instances in AWS, Azure, or GCP. There is no vendor lock-in to proprietary hardware. Organisations can deploy ViBE on their existing infrastructure, on low-cost commodity hardware, or on third-party appliances from any manufacturer. This flexibility extends to the operational model: ViBE can be deployed as a customer-premises appliance, as a cloud-hosted virtual appliance, or as a hybrid of both — adapting to the organisation's infrastructure rather than forcing the infrastructure to adapt to it.
