Introduction Definition As an application of QoS in VPN services, MPLS HQoS includes hierarchical QoS (HQoS) at the public network side based on the peer PE/VPN instance, and interface-based QoS at the access side of users. MPLS HQoS offers practical QoS solutions to various services in the MPLS VPN. Purpose With the development of Virtual …

IS-IS Traffic Engineering (TE) is an extension of IS-IS to support MPLS TE. As specified in RFC 5305 and RFC 4205, IS-IS TE defines new TLVsand sub-TLVs in IS-IS LSPs to carry TE information, floods LSPs to implement the flooding and synchronization of TE information, and transmits TE information to the CSPF module. IS-IS TE supports MPLS …

If there are no other routes with higher priorities to the target destination, these “equal-cost” routes are used. Packets transmitted to the target destination are sent along different routes and, in this way, …
Continue reading Basic Principles of Load Balancingl MPLS network forwards packet according to the label. But how does label be generated? What mechanism does MPLS adopt to implement data forwarding? l MPLS includes two plane: control plane and data plane. l Control plane’s charge is to generate and maintain routing information and label information. Data plane’s charge is conventional IP packet …
