2025: ME2001/ME5210S/ME6008
On November 5, 2025, Eltex introduced the next generation of ME backbone routers for carrier and corporate tasks.
According to the company, Eltex ME series backbone routers are a comprehensive solution for large networks of telecom operators and companies. This generation of devices creates a scalable architecture that can cope with increasing bandwidth and fault tolerance requirements.
The next generation ME series of Eltex backbone routers for November 2025 includes three models with different performance and functionality for three levels of IP/MPLS network - access, aggregation and kernel.
ME2001 is the younger model of the line with a fixed set of interfaces, performance - up to 300 Gbps. It is suitable for routing at the IPMPLS access/network level: the junction point of local L2/L3 segments with the trunk, the connection of base stations of mobile operators, including 5G primary traffic routing.
When traffic from multiple such access edge devices needs to be pieced together at one node for further transmission, the ME5210S is connected. Its 920 Gb/s performance and fixed set of performance ports effectively solve aggregation layer problems by collecting traffic streams for transmission to the core of the MPLS network.
ME6008 is a modular chassis-platform with maximum performance of 19,2 Tbit/s for creating a core of trunk networks, where the main volumes of traffic from the entire network flock.
ME6008 provides high-speed switching and aggregated traffic transmission between IP/MPLS network nodes. With eight slots for line interfaces, the port train is flexibly configured for specific deployment tasks. ME6008 has optimal scalability and fault tolerance at the module level. Model for November 2025 in development status.
routers The ME architecture is based on distributed processing of packets, their hardware switching and routing. Each device is based on specialized Control Plane control processors, which work in conjunction with high-speed packet and ASICprocessors TCAM coprocessors with a large table capacity (FIB). A significant amount of buffer memory for all presented ME models helps to smooth out peak loads and ensure high-quality operation of QoS mechanisms.
This architecture provides stable performance even at maximum loads and complex routing configurations.
ME supports a full stack of IPv4 routing protocols/and IPv6 an exhaustive set of MPLS services: LDP (including FRR), mLDP, MPLS pseudowire with PW backup functionality, RSVP-TE, LDPoRSVP, CSC, etc.
MPLS Traffic Engineering provides tools for intelligent load balancing in the network. Explicitly specifying LSP routes will help bypass potential bottlenecks and ensure guaranteed bandwidth for critical services.
For modern multi-service delivery scenarios, EVPN/MPLS and EVPN/VXLAN are useful, which optimize the connection of distributed data centers.
Service quality is implemented at the level of advanced QoS capabilities, including configurable HQoS, for subtle allocation of resources to traffic classes and a guaranteed service level for services.
The deployment of mobile networks, including 5G, has dramatically changed the requirements for synchronization accuracy in telecommunications networks to nanoseconds. In ME, synchronization is implemented using SyncE and IEEE 1588 v2 (PTP) standards, which is critical for the operation of base station equipment.
L2VPN and L3VPN services (L2/L3-MPLS VPN, VPLS, VPWS, BGP/MPLS VPN) provide isolated communication channels with individual quality of service parameters for the needs of corporate clients and operators.
2024: Completion of ME5210S development
On August 12, 2024, Eltex announced that the development of the ME5210S, a trunk router with a fixed number of ports, has been completed, which is a development of the ME5200S model. This device is more compact, has optimized performance, supports time synchronization using the PTPv2 protocol (IEEE 1588v2) and introduces a number of functional changes.
According to the company, the ME5210S model received a more powerful Control Plane processor and an increased amount of RAM up to 64 GB - four times more than the ME5200S. Like other routers in the series, ME5210S is equipped with a packet processor that performs high-speed hardware switching and routing, and a TCAM coprocessor for fast work with routing tables. This ensures optimal switching and routing performance. The packet processor has a performance of 720 MPPS and has a large buffer memory with a capacity of 8 GB, which allows you to cope with outbreaks of network traffic.
The form factor of the case is ME5210S-19, "height 1U. The router takes up half the height of the rack compared to its predecessor, while the depth of the case has increased from 500 mm to 560 mm.
Interfaces: 32 10 Gb/s (SFP +) ports with the ability to work in 1 Gb/s mode, 6 100 Gb/s (QSFP28) ports with the ability to work in 40 Gb/s mode. The number of 100 Gb/s ports is increased by two compared to the previous model. Interface splitting and merging modes are supported: dividing the QSFP28 interface into 4x SFP28 or 4x SFP +; combining four SFP + interfaces into one QSFP +.
ME5210S offers an extensive set of functions, MPLS QoS, implements Traffic Engineering technologies to optimize the use of network resources and load balancing, supports a full protocol stack/, IPv4IPv6 accounts for traffic flows and uploads statistics on Netlow/IPFIX protocols. Thanks to these capabilities, the router can effectively solve a wide range of tasks in large corporate and carrier networks.
Key features:

- QoS: up to 8 queues per logical interface, queue types - Strict Priority (SP/PQ) and Deficit Weighted Round-Robin (DWRR), support for the WRED algorithm, traffic classification based on Ethernet-, IP-and/or MPLS-headers (802.1p, MPLS TC, IP-based DSCP lists), traffic labeling and HACL traffic processing
The ME5210S supports the PTPv2 protocol (IEEE1588v2) used to synchronize the time of network devices. The availability of this feature is critical for time-sensitive applications such as cellular operator backbone networks, grid management networks, etc.
On the front panel of the device there are connectors for connecting sources and receivers of time and frequency synchronization signals: 1PPS In/Out - input and output of time synchronization signals; 10 MHz In/Out - input and output of frequency synchronization signals; ToD - port for transmitting and receiving Time of Day information.
Time synchronization using the IEEE1588v2 protocol works in conjunction with the SyncE synchronization function, providing service redundancy.
The router hardware is equipped with redundant power supplies and cooling fans, which ensures uninterrupted operation of the device even in the event of a failure of one of the components. Hot-swappable power supplies and fans allow for non-disruptive maintenance. The software also implements fault tolerance tools. These include the Graceful Restart feature for routing protocols and the Non-stop forwarding function. The launch of the device into mass production is planned in IV 2024 quarter.
