Peering vs transit for DDoS protection: what changes during an attack?

Peering and IP transit do not behave the same way under DDoS pressure. This guide explains the routing, capacity, economic and operational differences for protected networks.

Multi-upstream DDoS protection: why one transit provider is rarely enough

A multi-upstream DDoS design combines several transit providers, routing policies and mitigation layers to reduce single points of failure. This guide explains what it solves and what it does not solve by itself.

Upstream filtering DDoS: stopping attack traffic before it saturates your infrastructure

Upstream DDoS filtering protects a service before the attack reaches the customer port, firewall or server. This guide explains when it is useful, how it differs from blackholing and how to combine it with clean traffic delivery.

IP transit latency: how routing, PoPs and DDoS protection affect performance

IP transit latency is not only a matter of distance. BGP decisions, PoP location, return path, tunnels and mitigation design all influence how users experience a protected service.

How BGP works: prefixes, AS paths, routing decisions and DDoS impact

BGP is the protocol that lets networks announce reachability to each other. Understanding prefixes, AS paths, communities and route preference is essential before buying protected transit.

BGP Blackhole vs BGP FlowSpec: choosing the right DDoS filtering tool

Blackholing saves capacity by sacrificing a destination. FlowSpec can remove attack traffic more precisely, but only when rules are short, measurable and reversible.

Anycast DDoS protection: when it helps, when it does not

Anycast distributes traffic toward several points of presence, but it is not a magic shield. The clean delivery model after mitigation still decides latency, stability and customer experience.

Route hijacking and DDoS: how BGP incidents can turn into outages

A route hijack can divert, intercept or blackhole traffic before packets reach your infrastructure. DDoS planning must include routing security, monitoring and fast withdrawal procedures.

BGP FlowSpec packet length filtering: when size-based DDoS rules help

Packet length filtering can remove repetitive floods with stable sizes, especially UDP reflection or garbage floods. It becomes dangerous when legitimate protocols share the same size profile.

BGP FlowSpec TCP flags: using SYN, ACK and RST matches without breaking real traffic

TCP flags can make FlowSpec rules precise against SYN, ACK or RST floods, but they become risky when they ignore connection state, asymmetric routing and legitimate protocol behavior.

BGP FlowSpec limitations: what it can filter and where it becomes dangerous

BGP FlowSpec is powerful for upstream relief, but it is not a full mitigation engine. Its limits appear around state, context, provider support, rule scope and false-positive risk.

DDoS protection over VXLAN or IPIP: when should you use them?

VXLAN and IPIP do not solve exactly the same clean traffic delivery problem after DDoS mitigation. This guide explains when each one makes sense, which limits matter and how to choose a model that matches your topology, edge design and operations. It also helps compare VXLAN, IPIP, GRE, clean handoff and post-mitigation traffic delivery with an operator-grade architecture, operations and buying logic.
