  • MPLS trap

MPLS MPLS TE
  • Static CR-LSP

  • RSVP-TE

  • RSVP-TE authentication in compliance with relevant standards

  • Auto routing

  • FRR

  • One-to-one backup FRR: an MPLS TE FRR mode. After the detour attribute is configured for the primary tunnel, a detour LSP can be automatically established to protect an LSP on the primary tunnel. The detour LSP is a part of the primary tunnel. When the primary tunnel is established, detour LSPs are automatically established as needed. They are changed or deleted together with the primary tunnel.

  • CR-LSP backup

  • P2MP TE

  • 1:1 protection switching

MPLS

MPLS LDP

  • LDP Remote-LFA FRR

    LDP remote LFA FRR is a supplement to LFA LDP FRR. LFA LDP FRR uses the LFA FRR algorithm that can only protect LDP LSPs in 70% of all scenarios. After the remote LFA technique is implemented, FRR takes effect in more than 96% of all scenarios.

    The LDP module receives the remote LFA FRR next-hop address of a route prefix sent by the RM module. The LDP module uses the carried PQ node address to create an LDP remote peer and sends a Target Hello message to its peer to establish a remote LDP session. The PQ node address is used as a next-hop IP address for a remote-LFA FRR LSP. The actual next-hop IP address and outbound interface name are used to establish an LDP LSP destined for the PQ node. This LDP LSP allows for iteration of the remote LFR LSP.

    On the PQ node, the auto-accept function is configured. This function enables the PQ node to use information in the received Target Hello message to automatically establish a remote LDP peer. The PQ node then sends a Target Hello message to its peer to establish a remote LDP session. Label Mapping messages are then transmitted over the remote LDP session to establish a tunnel.

Segment Routing

SR-TE

Segment routing (SR) is a new Multiprotocol Label Switching (MPLS) technique that uses the extended Interior Gateway Protocol (IGP) protocol and MPLS labels on control and forwarding planes, respectively. A routing segment is represented as an MPLS label on the forwarding plane.

SR-Traffic Engineering (SR-TE) is a new Multiprotocol Label Switching (MPLS) Traffic Engineering (TE) tunneling technique implemented based on an Interior Gateway Protocol (IGP) extension. The controller calculates a path for an SR-TE tunnel and forwards a computed label stack to the ingress configured on a forwarder. The ingress uses the label stack to generate an LSP in the SR-TE tunnel. Therefore, the label stack is used to control the path along which packets are transmitted on a network.

The NE40E supports the following SR-TE functions:

  • Strict label stack
  • Stitching label
  • L2VPN, L3VPN, and LDP over SR-TE
  • Hot standby (HSB) LSP, and BFD for SR-TE LSP

EVPN offers the following benefits:
  • Improved link usage and transmission efficiency: EVPN supports load balancing, fully utilizing network resources and reducing network congestion.

  • Reduced network resource consumption: By deploying RRs on the public network, EVPN decreases the number of logical connections required between PEs on the public network. In addition, EVPN enables PEs to use locally stored MAC addresses to respond to ARP Request messages from connected sites, minimizing the number of broadcast ARP Request messages.

The following deployment models are supported:

  • EVPN E-Line

Packet injection is supported.

Virtual Access IP RAN Virtual Cluster Access

Virtual cluster access centralizes control planes to allow one or two aggregation nodes to control all access nodes on a virtualized network. Multiple network devices are integrated into one device on the control plane.

IP RAN virtual cluster is deployed on the access network that consists of CSGs and AGGs.

On an IP RAN virtualization network, virtual cluster nodes are classified as master or AP. The master provides the virtual control plane, and APs are controlled by the master.

router is a new type of master at the original AGG location. APs are ATN devices at the original CSG locations.

The IP RAN virtual cluster access offers the following benefits:
  • Simplified network planning

    Access ring planes are centralized on AGGs, and the AGGs calculate forwarding paths and allocate entries for the whole network. The primary and backup paths can be calculated without manual planning.

    IP RAN virtual cluster uses IS-IS to calculate routes. Therefore, IP addresses do not need to be configured for CSG interfaces with the virtual cluster enabled, which simplifies IP address planning.

  • Simplified service deployment

    Dynamic protocols (such as RSVP-TE, LDP, and BGP) no longer run on CSGs on the access ring, which significantly simplifies networking and reduces device loads.

  • Simplified O&M and reduced costs

    The plug-and-play is implemented. Adding or deleting an AP requires only the configurations on this AP and the master to be updated, which dramatically reduces manpower costs.

    IP RAN virtual cluster access requires less dynamic protocols. An AP reports only a few alarms (such as link Up/Down alarms), and a master performs centralized reporting and management for virtual cluster alarms (such as LSP Up/Down and PW Up/Down alarms), which facilitates fault locating.

VPN IP hard pipe

IP hard pipe technology strictly isolates soft and hard pipes by reserving hardware, carrying leased line services of high-value customers, reserving service bandwidth, and ensuring low delay for services. IP hard pipe is an IP-based access technology that provides bandwidth guarantee and low delay as well as service-specific granular OAM and SLA monitoring, allowing IP networks to provide leased line access services through high-quality independent pipes.
