A national IPTV network is only as good as its routing. Anycast, ECMP and BGP are how you send each viewer to the nearest healthy edge — and reroute them in seconds when one fails.
Running edges in Kolkata, Delhi and Mumbai is easy. Getting each viewer to the right one automatically, and moving them when a PoP dies, is the job of three routing tools.
Announce your edge service via anycast from all three metros. A Delhi viewer’s traffic is routed to the Delhi PoP because it’s nearest; a Mumbai viewer to Mumbai. ECMP load-balances within a PoP. If a PoP fails and stops announcing, BGP withdraws the route and users automatically fall to the next-nearest PoP — no DNS change, no manual intervention.
Anycast + BGP give you nearest-PoP routing and automatic failover from the same mechanism: when a PoP stops announcing, the internet just stops sending it traffic. That’s resilience built into the routing, not bolted on top.
This is also how IXP peering is realised: your BGP session at each exchange announces your edge to the regional ISPs peering there, so their subscribers reach you locally and cheaply.
Anycast for stateful sessions needs care — a mid-session reroute can break a connection unless the design is stateless at the edge. Token-validated, stateless edges (which HySky uses) tolerate rerouting cleanly.
