Design of mixed MPLS/OSPF routing in IP networks

Dzida, Mateusz ; Zagozdzon, Michal ; Pioro, Michal LU and Tomaszewski, Artur (2006) In Systems Science 32(3). p.55-59
Abstract
In this paper, we address some Internet core network optimization issues related to a combination of Open Shortest Path First (OSPF) and Multi Protocol Label Switching (MPLS) routing protocols. Since MPLS can be combined with any routing protocol there has appeared an idea of coupling IP streams routed via the OSPF protocol and MPLS Label Switched Paths (LSPs) in the same network. One expected advantage behind such a combined routing is to adjust the design stage by allowing some flows to be routed via OSPF while others to be transmitted via MPLS LSPs. In the paper we discuss two routing optimization problems. In the first case, OSPF routing protocol works over logical network with generalized IP links. These links are either standard IP... (More)
In this paper, we address some Internet core network optimization issues related to a combination of Open Shortest Path First (OSPF) and Multi Protocol Label Switching (MPLS) routing protocols. Since MPLS can be combined with any routing protocol there has appeared an idea of coupling IP streams routed via the OSPF protocol and MPLS Label Switched Paths (LSPs) in the same network. One expected advantage behind such a combined routing is to adjust the design stage by allowing some flows to be routed via OSPF while others to be transmitted via MPLS LSPs. In the paper we discuss two routing optimization problems. In the first case, OSPF routing protocol works over logical network with generalized IP links. These links are either standard IP links or IP links established as MPLS LSPs. In the second case, we distinguish two types of demands depending on whether OSPF routing is used or packets are switched by MPLS Label Switch Routers (LSR). We present both problem formulations and discuss the question on how to effectively solve these problems. (Less)
