Peeryx Flow Collector：防御の合図は、お客様のネットワークから
sFlow、NetStream、IPFIXの計測データを、PeeryxのオンデマンドDDoS対策につなぐ無料のコレクター。しきい値と対象プレフィックスはお客様が決められます。
通信量の測定とネットワーク運用。
有効な観測には時刻、対象範囲、再現可能な方法が必要です。測定、容量判断、障害対応を結び付け、変更の理由と戻し方を明確にします。
テレメトリーとインライン処理、物理容量の推定と実測ソフトウェア限界を区別します。サンプリング、集計間隔、カウンターの定義によってグラフから判断できる範囲が変わります。

適切な場所から観測する
時刻を合わせてサービス状態とインターフェース・フロー情報を収集します。欠落標本を通信停止と解釈する前に、エクスポーターへの到達性とデータの鮮度を確認します。
速度と経路を同じ条件で比較する
PPS と Gbps の比較には同じパケット長の定義と測定期間を使います。トンネルやフィルター変更を含め、実際の配信・戻り経路で遅延を比較してください。
変更とロールバックを準備する
期待効果、担当者、失敗判定値、戻す操作を記録します。ノード停止時の容量を試験し、切り替え前に障害連絡先を用意します。

DDoS PPS vs Gbps: compare packet pressure without misleading benchmarks
Convert bandwidth and packet rate with explicit Ethernet assumptions, locate the bottleneck and distinguish wire-rate arithmetic from measured filtering capacity.
DDoS protection costs: compare the complete service
Build a comparable DDoS budget across protected transit, filtering software, hardware and game delivery, with clear commit, percentile and overage assumptions.
How to stop a DDoS attack: emergency response, mitigation and clean traffic delivery
A practical guide to stopping a DDoS attack without improvising: identify saturation, protect legitimate users, activate mitigation, choose between blackhole, FlowSpec, protected IP transit, tunnels or reverse proxy delivery, then restore clean traffic safely.
Why low latency still matters under DDoS mitigation
Under attack, staying online is not enough. Useful Anti-DDoS protection must also preserve stable latency, controlled jitter and clean delivery for legitimate traffic.
What to do when your hoster’s Anti-DDoS is no longer enough
When your hoster’s Anti-DDoS is no longer enough, the worst decision is often to migrate in a hurry. This guide explains how to identify the real limit, keep the existing server when possible, then add specialised protection with tunnels, reverse proxy, router VM or protected IP transit.
How to migrate from a hoster Anti-DDoS to specialised protection without changing server
You can upgrade DDoS protection without moving machines, reinstalling services or leaving your current hoster. The goal is to place a specialised network layer in front of the existing infrastructure, filter attacks there, then deliver clean traffic back to the same server.
How to choose an Anti-DDoS provider without getting trapped
Choosing an Anti-DDoS provider should not be reduced to a Tbps number or a promise of unlimited protection. What matters is how traffic enters the mitigation layer, how it is filtered, how clean traffic is delivered back, what visibility you get during an attack and which limits actually exist.
Low-latency DDoS protection in Europe: why Marseille is strategic
For low-latency DDoS protection in Europe, the location of the scrubbing point matters as much as raw capacity. This guide explains why Marseille is strategic for southern France, Iberia, Italy, the Mediterranean and traffic entering Europe from the south.
Anti-DDoS protection for VoIP, gaming, web and latency-sensitive services
VoIP, gaming, interactive web, APIs and real-time services need Anti-DDoS protection built around latency, jitter, false positives and clean traffic delivery. This guide explains how to protect sensitive services without degrading their normal quality.
How to protect a multi-site infrastructure against DDoS attacks
Protecting a multi-site infrastructure against DDoS attacks requires a full architecture: routing, protected IP transit, clean handoff, role segmentation between sites and credible failover paths. This guide helps design multi-site protection that stays usable in real operations.
Buying DDoS protection: an operator’s checklist
Compare the actual traffic path, packet workload, delivery limits and acceptance evidence before committing to a DDoS service or filtering platform.
PPS and Gbit/s: build a network test plan
Define packet sizes, legitimate traffic and measurement points before comparing filtering configurations.
Latency, asymmetric routing and clean traffic: what really matters in anti-DDoS
Capacity alone is not enough. You also need to understand latency, asymmetric routing, clean traffic delivery, Gbps and Mpps to choose a credible and buyable architecture.
DDoS impact on a network: links, routers, queues and customer services
A DDoS attack does not only affect the targeted server: it can saturate links, routers, queues and neighbouring services.
Anti-DDoS latency explained: how mitigation affects real service quality
DDoS mitigation can add latency when routing, filtering or clean traffic delivery are poorly designed. Learn what really matters before choosing a protection model.

Flow Collector はデータ経路外で観測し、許可された保護処理を開始できます。計算ツールはリンク・サーバー容量の計算根拠を示しますが、隔離環境の検証試験を代替しません。
