TMX 880 MPLS core switch

Product Overview
TMX 880TM is a scalable, high-performance MPLS platform with industry-leading QoS processing capabilities. It is mainly used to transmit various services, such as ATM, frame relay, and IP addresses, in the carrier's core network. Its patented switching structure is used to dynamically support layer 2nd and layer 3rd protocols-including Multi-Protocol Label Switching MPLS), ATM, frame relay, and IP. TMX 880 supports multiple interfaces, allowing service providers to flexibly expand their current network or port to the IP/MPLS backbone network.
TMX 880 is the latest core product of longxun multi-service exchange product series, through the BSTDX-8000/9000, CBX500, GX550, SpringTide? In combination with 7000 IP service switches, service providers can build reliable multi-service networks, all of which run under the common switch software and public network management system.
Service supplier requirements 
In the traditional era, service providers mainly provide frame relay and ATM services to large enterprise customers to obtain most of their high-profit data revenues. As the competitive environment changes (such as the relaxation of long-distance data market control), operators have expanded FR/ATM networks to provide MPLS-based layer-3 IP services. At the same time, broadband services are widely used, and the profits of basic connection services are declining. To survive, service providers need to expand their existing networks and provide value-added services so that their services have obvious advantages. On the other hand, investment by service providers is decreasing, and operating expenditures are increasing. Therefore, any solution must consider these factors.
To meet these requirements, we usually consider three solutions, but each solution has shortcomings:
1. add an ATM switch to the core of the FR/ATM network-the advantage is that it supports multiple businesses and provides strict QoS, but there is a cell tax when transmitting IP services. Considering that the increase in IP traffic is much higher than that of ATM, therefore, the ATM switch may not be a good long-term investment.
2. Add a large router to the core of the FR/ATM network-the advantage is that the IP transmission efficiency is high, but the IP router structure is not suitable for transmitting multi-service traffic and lacks QoS functions.
3. in addition to FR/ATM networks, building a separate IP network-building a separate network is costly and brings about interoperability with existing FR/ATM networks and higher transmission and operation costs. Moreover, the commercial cases of advanced IP services do not prove that the current capital investment is reasonable.
The solutions required by current service providers should be able to smoothly expand their existing FR/ATM networks and provide a transmission platform for future IP businesses. This solution can protect their existing investment, and minimize investment.
Meet the needs of service providers
The TMX 880 MPLS core switch enables service providers:
■ Scalable and profitable Frame Relay and ATM services
■ Deploy the same platform to support IP Services
■ Integrate existing networks to minimize operating costs
TMX 880 uses a group-based switching structure to provide high performance and scalability that cannot be provided by cell-based transmission. In addition, TMX 880 is designed based on the connection-oriented structure to provide high service quality, meet SLA business requirements, and achieve more comprehensive control and faster fault recovery. All of this is based on the unique vswitch hardware and strictly guaranteed QoS of TMX 880. Finally, TMX 880 is managed by Navis, allowing TMX 880 to be seamlessly integrated into existing customer networks, reducing operating costs.

This structure also supports multiple queuing levels to provide the QoS levels required for ATM and frame relay. TMX 880 ensures extremely low latency and latency jitter so that service providers can meet their SLA (SLA requirements ).
Provides rich ATM features
Like an ATM switch, TMX 880 can provide a large number of virtual circuits to support broadband services. TMX 880 fully complies with the multi-vendor interoperability standards and protocols of ATM. It also supports multiple signaling protocols, including VNN and PNNI interconnection, to achieve rapid establishment of virtual circuits.
Greater scalability to achieve optimal efficiency at the core
As service providers expand their networks, they can use the same TMX 880 chassis to expand their networks and reduce investment costs. The switch provides the performance required to increase current network capacity and functionality, including a full range of interfaces from OC-3c/STM-1 to OC-192c/STM-64 and Gigabit Ethernet. TMX 880 supports up to 128 OC-3c/STM-1, 64 OC-12c/STM-4, 64 OC-48c/STM-16 and 16 OC-192c/STM-64 interfaces, provides low latency and extremely high port density within a small footprint. In order to effectively support ATM services on the MPLS core, TMX 880 encapsulates layer-4 and provides cell and grouping modes based on the current standard draft. The Fluid SignalingTMX 880 switch that fully communicates with each other enables seamless integration with multi-service networks by maintaining the unique features of end-to-end ATM QoS in the MPLS core. Vswitch's low latency, hardware queuing mechanism, and support for MPLS Traffic Engineering ensure end-to-end QoS of each virtual circuit, and ensure the bandwidth of the entire MPLS core network. TMX 880 supports multiple layer 2nd and layer 3rd protocols, including MPLS, IP, frame relay, and ATM. When the hybrid business grows and changes, the chassis can be configured to support any combination of these protocols based on each port for flexibility. Lucent has a successful history of connecting multiple signaling systems on a general network: In the ATM Backbone Network, CBX500 enables intercommunication between ATM and FR to expand the FR Access Network Based on BSTDX. The Fluid Signaling feature of TMX 880 enables service providers to support full network transparency on the runtime, transmission, and QoS layers.
Proven carrier-level reliability and performance
In terms of structure, TMX 880 supports public device redundancy and distributed processing, with 99.999% availability for cards, chassis, and power modules. TMX 880 supports redundant routing control processor (RCP) to take over the main processor function when the main processor fails. In addition, the modular operation software of the vswitch can ensure the moderate restart of Open Shortest Path First (OSPF) and Border Gateway Protocol (BGP. In short, these features enable TMX 880 to upgrade software without interrupting services.
TMX 880 can also achieve high availability and Path-level redundancy at the network layer. These features include MPLS fast route reselection, comprehensive tag switching path (LSP) backup, and SONET 1 + 1 Automatic Protection Switching (APS ), the carrier can implement the Routing Protection Scheme Based on the availability level and profit required by the user. Each line card in the TMX 880 switch has a programmable hardware forwarding engine that can be separately configured. The central RCP is responsible for calculating the route and forwarding the route to the corresponding line card distribution. When hybrid services change, this distributed forwarding mode provides scalability, high reliability, and flexibility.
Lucent has helped the world's largest operators build their FR/ATM networks, and we will continue to apply this experience to help them deploy MPLS networks.

Business Application
Expand existing ATM and Frame Relay networks to meet fast-growing traffic requirements
Currently, Frame Relay and ATM networks have been widely deployed by most operators, but these networks are beginning to encounter serious network congestion problems. With its 880 Gbps switching capacity and support for Frame Relay, ATM, and MPLS, TMX is ideal for extending these existing networks. One of the most typical business applications of the TMX 880 switch is to use the core switch to transmit complex multi-service traffic between multiple access devices and end users. This type of application is especially suitable for the existing CBX500/GX550 network, because Navis integration of TMX800 and VNN support functions can provide particularly effective and economical solutions.
As the MPLS Core Fusion, the separate IP address and Frame Relay/ATM networks use the multicast and QoS functions. The TMX 880 switch plays an important role in building a multi-service core of a converged voice and data network. In a network that integrates voice and data, various services are provided to all end users, such as DSL, PSTN, wireless, and next-generation H.323, or SIP. The operational reliability of the TMX 880 switch and its Multi-Service Support for MPLS, ATM, frame relay, and IP address make it flexible and scalable for networks that integrate voice and data.
Connect an independent ATM and IP/MPLS network as a gateway and minimize the number of devices

Currently, the networks of most service providers cannot communicate with each other, while many old operators have achieved growth through mergers and acquisitions, and hope to integrate multiple business networks into a single, seamless, and unified network. TMX 880 is suitable for connecting multiple networks on a single MPLS backbone network, transmitting multiple types of traffic and maintaining ATM-level QoS. By integrating multiple networks, service providers can ensure the uniformity and uniqueness of the traffic in their networks, achieving significant device and operation cost efficiency.
Provides operational QoS to existing networks that provide ATM and IP Services
TMX 880 is a viable option for providing high-speed and high-quality transmission required by ATM and IP services. Especially when it comes with leading access devices such as Lucent's SpringTide? 7000 when the IP service switch is combined with the Lucent Access Point1500/600/300, TMX800 can provide QoS-enabled differential IP service.
