Traffic Engineering

Traffic engineering is the set of techniques operators use to optimise how traffic flows through their network, load balancing, MPLS path selection, BGP local preference, and segment routing, so that capacity is used efficiently and SLAs are met. It is a key tool for both performance and resilience, and feeds into capacity planning and DDoS mitigation strategies.

Traffic Engineering in context

Signaling protocols carry the control-plane messages that set up calls, register subscribers and route SMS. SS7, Diameter, GTP-C and SIP are the four dominant families, and interconnect exposure of any of them is treated by GSMA as top-tier telecom risk.

Telecom threats range from opportunistic SMS phishing and SIM swap to nation-state grade location tracking. The common thread is that most attacks exploit the inherited trust model of legacy signaling protocols.

To place Traffic Engineering in the wider telecom-security picture, review Traffic Baselining, Lawful Interception Architecture, DPI, NetFlow / IPFIX / sFlow, Lawful Intercept and Capacity Planning: each entry cross-references back to this page so you can walk the topic in either direction.
