The traffic patterns and flows on the network are changing much faster than they were three or five years ago , says Andy Belcher , general manager of the telecom systems division at Hewlett-Packard Co. ( South Queensferry , Scotland ).Internet traffic is fundamentally of a different structure and nature than voice traffic - the PSTN [ public switched telephone network ] is architected for the average , three-minute voice call , but with the Internet , people stay on an open line for hours at a time.The public network was just not architected for that..
Local number portability ( LNP ) also has a critical impact on the network.Once a single number in any given NNX is ported , the carrier must do a database dip for every call to that NNX.LNP isn't widely used yet , but once it's implemented , it puts a significant additional pressure on the network , Belcher says.With database dips , the path of any call could end up being twice as long as it was before , which uses twice as many network resources..
The increasingly competitive business market is another major driver.Emboldened by a choice of carriers , business customers are starting to require service level agreements from their carriers , and demanding rebates if the guarantees are not met.As a result , carriers are more interested in preventing any network disruptions that could end up costing them money or , ultimately , a customer.
