2. XDP Technology Core

Our protection platform is built on eXpress Data Path (XDP) technology, providing kernel bypass capabilities that dramatically reduce latency and increase throughput compared to traditional userspace filtering solutions.

⚡Kernel Bypass

XDP processes packets directly in the kernel space, bypassing the traditional network stack for maximum performance. This allows us to filter packets at line rate with minimal CPU overhead.

Sub-microsecond packet processing
Zero-copy packet handling
Hardware offload support

🔍Advanced Filtering

Our XDP programs implement sophisticated filtering logic including stateful connection tracking, rate limiting, and behavioral analysis directly in the kernel.

Multi-layer packet inspection
Dynamic rule compilation
Real-time adaptation

📊Real-Time Analytics

Integrated monitoring and analytics provide instant visibility into traffic patterns, attack vectors, and mitigation effectiveness.

Sub-second metric collection
Flow-based analysis
Automated alerting

2.1 XDP Program Architecture

Our XDP programs are optimized for high-performance packet processing with the following structure:

// NVH Shield XDP Core Architecture
struct nvh_filter_context {
    __u32 src_ip;
    __u32 dst_ip;
    __u16 src_port;
    __u16 dst_port;
    __u8  protocol;
    __u64 timestamp;
    __u32 packet_size;
};

// Main XDP program entry point
SEC("xdp/nvh_shield")
int nvh_ddos_filter(struct xdp_md *ctx) {
    // Extract packet headers
    struct nvh_filter_context filter_ctx;
    
    // Rate limiting check
    if (check_rate_limit(&filter_ctx) == RATE_EXCEEDED) {
        return XDP_DROP;
    }
    
    // Behavioral analysis
    if (analyze_traffic_pattern(&filter_ctx) == MALICIOUS) {
        return XDP_DROP;
    }
    
    // Allow legitimate traffic
    return XDP_PASS;
}
