Techniques for troubleshooting IP based telecommunications networks

摘要

Techniques are disclosed for troubleshooting an IP telecommunications network. A network server sends a notification message to a plurality of IP addresses each associated with a customer endpoint. The server receives a notification response from each of the customer endpoint IP addresses and determines a response time for each of the customer endpoint IP addresses. The response times are compared to an expected notification response time and those that exceeded an expected response time are geo-located. Traceroutes are performed to customer endpoint IP addresses in the same geo-located area that exceeded the expected response time. All hops between the server and the customer endpoint IP addresses for each traceroute performed are geo-coded to determine impacted and non-impacted routes between the server and each customer endpoint IP address. IP traffic between the server and a customer endpoint IP address may then be re-routed from an impacted route to a non-impacted route.

1. A method comprising:
in a network based server situated in an Internet Protocol (IP) based packet data network:
sending a notification message to a plurality of IP addresses each associated with a customer endpoint;receiving a notification response from each of the customer endpoint IP addresses;determining a notification response time for each of the customer endpoint IP addresses;comparing the notification response time for each of the customer endpoint IP addresses to an expected notification response time;geo-locating the customer endpoint IP addresses that exceeded an expected notification response time;performing traceroutes to customer endpoint IP addresses in the same geo-located area that exceeded the expected notification response time period;geo-coding all hops between the server and the customer endpoint IP addresses for each traceroute performed to determine impacted and non-impacted routes between the server and each customer endpoint IP address; andre-routing IP traffic between the server and a customer endpoint IP address from an impacted route to a non-impacted route.
