Abstract
Routing protocols are the foundation of the highly connectivity in today’s world.They let the routers exchange information allowing them to select the best routes,based on some criteria, to connect the humankind.SPs usally guarantee their service totheir enterprise customers in the form of Service Level Agreements (SLAs) that specify levels of reliability. Any failure in those SLAs cost money to the ISP. Having a protocol that could converge quickly is thus extremely important. In this thesis, we analyse the LSPs exchange performances of the IS-IS protocol. We show that the exchange is not as fast as what we could expect from a routing protocol. We propose an extension to the protocol to support TCP and exchange LSPs over it. We show that with this extension we can decrease by a factor one hundred the time needed to exchange LSPs.
