Network Gateway MPLS Solution

Service providers are constantly facing the challenge of designing an ideal network infrastructure that is flexible enough to meet customers' increasing bandwidth and network access needs. As the support for Multi-Protocol Label Switching (MPLS) is increasingly recognized by the market, the Network is committed to introducing a complete high-performance core and edge MPLS layer-3 Switch and internet router.
VPC supports a wide range of MPLS functions, including: High-Performance MPLS edge and core router functions; fully supports RSVP-TE and LDP signaling; traffic engineering, with OPSF and IS-IS extension; support for flow engineering and Marini drafts on all OC-3c/STM1, OC-12c/IPv4 and OC-48c/ipv16 SONET/SDH ports; using the unique Gigabit Ethernet network and OC-48c Packet over SONET/SDH Network Processor Architecture (NPA) interface, the industry's only line-rate Traffic Engineering and the second-layer vpn of the Marini draft) service; the Marini draft channel can be composed of ports with and without tags, providing great flexibility for the metro network. The Label Switch Path is a strict or loose Label Switch Path) server Load balancer is supported on the main link, secondary link, and hot backup link, which enhances the reliability and flexibility of the MPLS network and extends the support of service quality and service category (QoS/CoS, provides different bandwidth services for different customer service levels.
The network company combines MPLS intelligence and control mechanisms with switching line rate performance to provide a solid network foundation for service providers to build their IP infrastructure, supports current and future solutions. Powered by the core and edge vrouters of MPLS networks and their complete high-performance switching product series, CEN can build a high-capacity network service that will go beyond the "local region ", connect to remote sites across man or wide area networks.
The MPLS solution provides network administrators with tools to adjust networks through traffic engineering, so that system operators can accurately control the consumption of trunk bandwidth. The continuous development of MPLS technology is crucial to the deployment of Virtual Private Networks and end-to-end service quality, it also provides flexibility, reliability, and fault tolerance for the network built on the "Shortest Path" and "best effort transmission" transmission mechanism. The combination of MPLS routers and VPC products with value-added features helps service providers to implement Scalable IP differentiated services. In addition, the configuration and implementation are more convenient and the management capability is stronger.
The MPLS function set provided by the Application Network. Service providers can provide the following services:
1. Traffic Engineering
Traditional routers forward information packets along the shortest path between the source and destination, resulting in super aggregation-some links may be used excessively, and public transmission router points are paralyzed, in general, the utilization rate on the link is too low. The Network Traffic Engineering enables network administrators to clearly guide traffic through the MPLS core. In some cases, a longer LSP may be more efficient because the bandwidth utilization of the path is low. The rich MPLS Traffic Engineering Features of the network agility ensure that the network administrator controls the entire network infrastructure, thereby ensuring effective traffic distribution and improving network efficiency.
2. Guaranteed bandwidth
The MPLS solution of the network agility includes advanced control mechanisms, allowing network administrators to clearly manage and control bandwidth consumption. Service providers can use MPLS to provide Differentiated Services for their customers and ensure end-to-end service quality for a variety of data transmission services, including voice, data, video, and other group-based services.
3. reliable connection
The MPLS implementation solution of the network agility network supports many industry-leading features, so that service providers can ensure network reliability, fault tolerance, and flexibility. Network administrators can achieve comprehensive LSP redundancy, including fast recovery on the primary, secondary, and hot backup links, to prevent customers' applications from time-out or data loss.
4. Ethernet VPN
The network's support for a draft standard of work for the ietf of the Marini draft to describe the second-layer frame transfer method on the MPLS network) enables service providers to be In the MPLS environment, based on VLAN or port-level attributes, we provide users with Ethernet VPN-Transparent LAN Service (TLS ). The network built using the network-based Ethernet VPN product provides attractive solutions for customers who want to change their ATM and Frame Relay services, because not only can provide the same connectivity between the office locations of the enterprise, but also the higher transmission rate and more flexible. Ethernet VPN provides Layer 2 transparency-the customer does not really know the actual transmission device or protocol used by the telecom operator to provide the service-each end of the line can only see its own device on the other end. This allows each customer to run independently and configure the network according to business needs. Customers can run any protocol they think is appropriate without being constrained by service providers.
5. MPLS exclusive, Ethernet intra 
With the powerful functions of MPLS Traffic Engineering, network administrators can establish and maintain an explicit path or channel on the IP trunk that supports MPLS ). Network operators can ensure reliable and fault-tolerant manageable bandwidth services by avoiding faulty links and ensuring the priority of QoS policies and service class CoS. The drafting channel for achieving the Ethernet VPN is built on the MPLS trunk supporting traffic engineering, which can ensure higher network performance, higher data flow validity, and security.
At present, the network has been constantly showing all important aspects of its MPLS Traffic Engineering and Ethernet VPN implementation. The Network has successfully participated in the multi-vendor interoperability test, proving that telecom operators can deploy the network-jie MPLS solution in a multi-vendor environment, it ensures interoperability when introducing next-generation MPLS-based network services.
