Bell Lab’s Future X Network and Network Function Interconnect

The last major carrier network transformation happened in 2000s when carriers all over the world replaced their multiple network silos comprising TDM, ATM, Frame Relay, and IP etc… for their voice, video and data traffic by a single QoS-enabled networking technology called MPLS. The new QoS-enabled MPLS technology allows a carrier to: Save capex and … Continue reading Bell Lab’s Future X Network and Network Function Interconnect

BGP EVPN and All-Active Multi-Homing Ethernet Segment

BGP MPLS-Based Ethernet VPN or BGP EVPN (RFC 7432) offers more scalable, flexible (e.g., per flow and service load balance) and resilience (e.g., Multi-Home) Overlay layer 2 (L2) and layer 3 (L3) network services than the older TLDP and MP-BGP VPN based L2 and L3 MPLS network services designed in 2000s. BGP EVPN supports the … Continue reading BGP EVPN and All-Active Multi-Homing Ethernet Segment

BGP EVPN NVO and Data Center Interconnect with Nokia 7750 and Juniper MX – Part 1

In my previous blogs, I showed how to provision MPLS-based network services such as ePipe, VPLS and L3VPN (VPRN), which are common network services offered by carriers all over the world. One would note that the L2 epipe and VPLS, and the L3VPN network services have a very different control plane design. For the layer … Continue reading BGP EVPN NVO and Data Center Interconnect with Nokia 7750 and Juniper MX – Part 1
