What is Anycast

ScenarioPacket ReplicationReceiver
UnicastUnicastCommunication from a single source to a single receiverNo need for replication
MutilcastMulticastCommunication from a single source to several receiversMultiple copies needed
BroadcastBroadcastCommunication from a single source to all resources within its subnetMultiple copies needed
AnycastAnycastCommunication from a single source to a group of receivers, but the actual receiver is still one, determined by routing protocolNo need for replication

Differences from Ordinary EIP

  • Ordinary EIP: Declared in a single Region, global players need to access across Regions via the public network. High latency, high jitter.

  • Anycast EIP: Declared in multiple Regions, global player users access the UCloud Global backbone network from the nearest point and complete the transmission via the UCloud Global dedicated line. Low latency, low jitter.

Global Acceleration

Outgoing Traffic

  • Transmitted directly to the public network through the source UCloud Global node.

Incoming Traffic

  • Inter-room backhaul: Public network routing uses BGP to select the route, chooses the appropriate room entrance according to the principle of proximity, and sends the traffic to the corresponding POP point of UCloud Global, and then completes the backhaul through the dedicated line.

  • Backhaul in the same room: The public network is routed to the POP point in the same room, and then the backhaul is completed through UVER transmission.
