Pure IP operates a significant MPLS network spanning from New York to China including 46 cities within China. Colocation facilities are avialable in HongKong, NewYork, Sydney,and London. The MPLS network seamlessly integrates with the Pure IP voice backbone in London,Sydney, Auckland and New York to offer corporates an integrated and secure solution.
MPLS-enabled Wide Area Network (WAN) are network-based solutions that offer more bandwidth for the spend, faster application deployment, lower network operating costs, and more access options than traditional WAN services. Business can now benifit from competitive service Level Agreements on network availability, packet loss, latency, and jitter
MPLS provides networks with a more efficient way to manage applications and move information between locations. With the convergence of voice, video and data applications, business networks face increasing traffic demands. MPLS enables class of service (CoS) tagging and prioritization of network traffic, so administrators may specify which applications should move across the network ahead of others. This function makes an MPLS network especially important to firms that need to ensure the performance of low-latency applications such as Video and their other business-critical functions. MPLS Networking
MPLS gives network operators a great deal of flexibility to divert and route traffic around link failures, congestion, and bottlenecks. From a QoS standpoint, ISPs will better be able to manage different kinds of data streams based on priority and service plan. For instance, those who subscribe to a premium service plan, or those who receive a lot of streaming media or high-bandwidth content can see minimal latency and packet loss. When packets enter a MPLS-based network, Label Edge Routers (LERs) give them a label (identifier). These labels not only contain information based on the routing table entry (i.e., destination, bandwidth, delay, and other metrics), but also refer to the IP header field (source IP address), Layer 4 socket number information, and differentiated service. Once this classification is complete and mapped, different packets are assigned to corresponding Labeled Switch Paths (LSPs), where Label Switch Routers (LSRs) place outgoing labels on the packets. With these LSPs, network operators can divert and route traffic based on data-stream type and Internet-access customer.
