 ## Routing via Microsoft global network
 
-When you route your traffic via *Microsoft global network*, traffic is delivered over one of the largest networks on the globe spanning over 130,000 miles of fiber with over 165 edge POPs. The network is well provisioned with multiple redundant fiber paths to ensure exceptionally high reliability and availability. The traffic engineering is managed by a software defined WAN control that ensures low latency path selection for your traffic and offers the premium network performance.

 **Ingress traffic:** The global BGP Anycast announcement ensures ingress traffic enters Microsoft network closest to the user. For example, if a user from Singapore accesses Azure resources hosted in Chicago, USA then traffic is entered into Microsoft global network in Singapore Edge Point Of Presence (PoP) and travels on Microsoft network to the service hosted in Chicago.
 
-**Egress traffic:** The egress traffic follows the same principle. Traffic travels majority of its journey on Microsoft global network and exists closest to the user. For example, if traffic from Azure Chicago is destined to a user from Singapore, then traffic travels on Microsoft network from Chicago to SIngapore, and exits the network in Singapore Edge Point Of Presence (PoP).

-Both ingress and egress traffic stays bulk of the travel on Microsoft global network. This is also called cold potato routing.

 ## Routing over public Internet (ISP network)
 
-The new routing choice **Internet routing** minimizes travel on Microsoft global network, and extensively uses transit ISP network. This cost optimized routing option offers network performance comparable to other cloud providers.

-**Ingress traffic:** The ingress path uses hot potato routing that means that traffic enters Microsoft network closest to the hosted service region. For example, if a user from Singapore accesses Azure resources hosted in Chicago then traffic travels over public internet and enters Microsoft global network in Chicago.
