Cedarcom

Multi Protocol Label Switching (MPLS) has become the trend technology for providing virtual private network (VPN) services worldwide. MPLS is being used to engineer the core network more easily and efficiently (traditional MPLS and MPLS traffic engineering), to provide VPN services (MPLS-VPN), and to facilitate quality of service (QoS) across a network core (MPLS-DBP). All major carriers offer MPLS based services like Equant, Infonet, Cable & Wireless, AT&T, BT Ignite, Telia, Telecom Italia, Telefonica, WorldCom, MCI, NTT, Versatel, Teleglobe, etc. For more information, please visit our MPLS site at: www.cedarcom.net/mpls.asp

MPLS Benefits

Cedarcom MPLS network combines the benefits of both layer 2 switched networks and IP layer 3 networks.

A.	Layer 2 networks advantages: security and fast switching. Fast Switching: MPLS backbone routers switch based on MPLS labels, not on IP addresses. This makes switching faster and more efficient.
	-	Security: MPLS networks offer equivalent security by implementing MPLS VPN. MPLS VPN divides every backbone router into multiple virtual routers. This means that every customer has a separate and independent routing table on the provider backbone.
	-	Fast Switching: MPLS backbone routers switch based on MPLS labels, not on IP addresses. This makes switching faster and more efficient.

B.	Layer 3 networks advantages: dynamic networks Layer 3 networks offer extra flexibility and permit dynamic routing to be deployed. In case a remote router becomes unreachable due to a link failure, dynamic protocols ensure that traffic uses another route to get to its destination. All this happens seamlessly without human intervention. MPLS does provide this dynamic feature since it uses MPBGP (Multi-protocol BGP) to generate forwarding tables. Such features are not available in FR or ATM based networks, where all routing is statically configured! Difference between MPLS based services and Frame Relay/ATM/Leased Line based services It is widely considered that FR/ATM/LL based services as reliable but not scalable. MPLS has the best of both worlds: Privacy and Quality of Service of ATM and Frame Relay + Flexibility and Scalability of IP. MPLS based IP-VPNs provide EQUIVALENT security to Frame Relay without requiring the use of Encryption. MPLS based networks compared to Frame-Relay and ATM networks MPLS networks rely on MP-BGP (multi protocol BGP) in order to generate forwarding tables. The combination of MPLS and MPBGP gives Cedarcom the ability to dynamically shift traffic from the main route to an alternate one, in case the main route fails. This is a clear advantage over FR and ATM networks that require human intervention on the backbone, in order to change the statically configured routes. MPLS based services deployed around the World Cedarcom is the ONLY data operator providing MPLS based services in Lebanon. It is the ONLY WIRELESS data operator providing those services in the Middle East. Major worldwide carriers offer MPLS based VPNs and services like: Equant, Infonet, Cable & Wireless, AT&T, BT Ignite, Telia, Telecom Italia, Telefonica, WorldCom, MCI, NTT, Versatel, Teleglobe, etc. Trend in Data Communication in the world MPLS is a reality and taking over the data communication markets. This is what global carriers say: Infonet says MPLS VPNs are winning 60% of the RFPs. Cegetel says 80% of the requested quotes are MPLS. 20% are Frame Relay. Ovum market research forecasts that MPLS VPN will outtake IPSec VPN by more than double.
