Methods for Measuring End-to-End Latency and Scaling SMS based Service with Constant E2E


Gopi Krishnan Nambiar


Vol. 13  No. 3  pp. 7-13


SMS is one of the most widely used data applications in the world. Due to its easy availability and low cost, many enterprises have chosen to use SMS as the primary medium for dissemination of information and alerts. During high loads and traffic scenarios, the SMS latency tends to rise exponentially, which is a concerning situation for these enterprises. Two strategies, namely geo affinity based routing and traffic based load balancing have been proposed in this paper for maintaining constant end-to-end latency values under high load scenarios. We have carried out experiments on a live and popular SMS based service in India ‘txtWeb’, measured the end-to-end latency using an Android app and have found the latency remained constant even under increasing loads after these methods were implemented in the txtWeb ecosystem.
