Routers configure their paths based on the Link State Database (LSDB) in order to meet service requirements and Quality of Service (QoS) guarantee. Internet routing can be categorized into intra domain routing and inter domain routing, and QoS should be guaranteed both at the intra and inter domains for end-to-end QoS guarantee. The LSDB can be easily managed and updated at the inter domain routing...
In the Internet, in order to guarantee Quality of Service (QoS), all routers have to manage their Link State Databases (LSDBs) and determine a routing path that satisfies service requirements based on the LSDB. In addition, routing protocols have to provide QoS not only in the intra- domain but also in the inter-domain to enable the end to end QoS guarantee. In the intra-domain routing, it is possible...
Routers determine a routing path considering network topology and link state information for guaranteeing quality of service (QoS). Therefore, it is important that routers should know link state information so as to calculate a routing path. However, if routers generate link state update messages inordinately, their router performance may be reduced due to the processing burden of link state update...
The current Internet protocol (IP)-based networks face tremendous requirements such as quality of service (QoS) guarantees, efficient traffic engineering (TE), network scalability, and high network performance, in accordance with the emergence of diverse Internet services. A constraint-based routing path is determined based on network topology and link state information to guarantee QoS. It is necessary...
