Multiprotocol Label Switching (MPLS)
One solution for many protocols. Multiprotocol Label Switching (MPLS) is the key transport technology for both current and future packet and optical networks. Sysmetlab is a leading provider of MPLS software suites, including software protocols for MPLS, MPLS-TP and GMPLS control planes used to build MPLS-enabled networking equipment for core networks, mobile backhaul networks and data center overlay networks. Sysmetlab’s MPLS software suite, along with Sysmetlab’s Intelligent Switching Solution (ISS), allows network equipment manufacturers (NEMs) to accelerate development of feature-rich, easily manageable, scalable and resilient network equipment.
MPLS Implementation
Sysmetlab MPLS implementation is an efficient and portable implementation of the label-switching capability mechanism. It supports Layer 2 VPN, Layer 3 VPN and GMPLS extensions for packet-switched networks, and enables migration of existing IPv4 networks to IPv6, leveraging the VPN Provider Edge (6VPE) approach feature.
MPLS-TP Implementation
Sysmetlab MPLS-TP implementation is a portable implementation of the MPLS-Transport Profile, providing path protection switching, QoS and OAM capabilities to enable end-product traffic engineering, fault management and faster switching capabilities.
