QoS-aware multi-plane routing for future IP-based access networks

Analysis of Practical Aspects of Multi-Plane Routing-Based Load Balancing Approach for Future Link-State Convergent All-IP Access Networks

“…A reference scenario was studied for MPR in [11] and [12] where the RP structure's construct was such that only dedicated RPs (i.e. paths) for every Gateway (GW)-Aggregation Router (AR) pair were considered.…”

“…MPR is comprised of an offline TE method that serves to build logical Routing Planes (RPs) rendering a set of multiple shortest paths between all Ingress -Egress routers ahead of the traffic flow in the network that is then governed by an online TE approach. MPR's online TE approach was initially presented in [11] and [12] serving a practical purpose of an integrated solution of distributing IP sessions over RPs.…”

“…[15] contains a theoretical study of the offline's quality of RPs when extended with internal traffic routing paths subject to hop-constrained optimization. Early practical results with the added internal traffic distributions for one topology are presented in [16] with the readjusted online TE approach as compared with [11] and [12].…”

QoS-aware multi-plane routing method for OSPF-based IP access networks

“…The non-linear cost function [15], [17] shown in (17) illustrates the method to nonlinearly combine additive QoS parameters, such as delay, jitter, reliability, packet loss, into a single cost metric for any path p d n in routing plane n for demand d while the non-additive ones such as bandwidth, as stated previously, is easily dealt with a preprocession step. Let ( : = 0 , 1 , .…”

“…In this paper, we extended and based our work on the research conducted by authors in [14] and [15], in which a link weight assignment algorithm for network planning and a traffic splitting adjustment algorithm have been developed for creating up to five OSPF routing planes on one hand, and then spreading traffic amid them following the rule same path for same flow. Routing plane is an installation of the standard OSPF routing protocol.…”
