Networking Scheme for Virtual Private LAN Service(VPLS) Based on Label Distribution Protocol (LDP) over MPLS
Lin Luo · Telecommunication Engineering · 2005
By analyzing the key technologiespseudo wire and Label Distribution Protocol (LDP)to implement the Virtual Private LAN Service (VPLS) in Multi-Protocol Label Switching (MPLS) networks, the authors discover the scale limitation of VPLS based on these technologies, which arises from the full mesh problem. Based on the hierarchical VPLS solution of IETF,the authors discuss two practical networking designs, which connect VPLS networks with different grade, to reduce the amount of pseudo wire, avoid full mesh problem, and improve the scalability of the VPLS networks.
