Case Study: KazTransCom achieves tenfold performance and resilient 10–40Gbps metro aggregation with Extreme Networks

Reliable Infrastructure for One of the Leading Telecommunications Service Providers of Kazakhstan

KazTransCom, one of Kazakhstan’s leading telecommunications service providers with more than 5,000 customers across 13 cities, faced rapidly growing corporate demand that outstripped its legacy aggregation networks. To build metropolitan aggregation rings (10–20 Gbps with headroom to 40 Gbps) across six fast‑growing cities, KazTransCom selected Extreme Networks hardware — deploying Summit x670‑48x, x460‑24x, x440‑24t (and x430‑24t) switches — to replace limited 1–2 Gbps Cisco‑based aggregates and enable a more scalable, resilient topology.

Extreme Networks’ solution used ring topologies with EAPS, Unified MPLS, 802.1ad (QinQ), MPLS/VPLS and IS‑IS to deliver fast convergence and multi‑service flexibility. The deployment reduced ring recovery to ~350–450 ms, supports up to 200,000 users, and boosted network performance more than tenfold while allowing capacity increases without re‑architecting the network. KazTransCom completed testing and rollout rapidly with Extreme Networks’ compatible Summit portfolio and responsive support, enabling immediate service improvements for enterprise customers.
