End-to-End Network Service QoS – Part 1

Before the arrival of MPLS and the advance in silicon technology for ASIC and network processors in early 2000s, many carriers ran multiple single-purpose networks such as TDM, ATM and IP to support their video, voice and data network services. Some enterprises attempted to consolidate their triple-play traffic onto a single IP network. However, due to the silicon technology and QoS … Continue reading End-to-End Network Service QoS – Part 1

MPLS Network Services – Traffic Engineering, Resilience and MTU

In the previous blogs, I showed how to interop among Nokia, Cisco and Juniper routers for different MPLS layers 2 and 3 network services such as ePipe, VPLS and VPRN using GNS3 and EVE-NG network emulators on a PC. The blogs demonstrate the flexibility and cost-effectiveness of network service design and interop using a PC. In … Continue reading MPLS Network Services – Traffic Engineering, Resilience and MTU

MPLS VPLS Interop – Nokia 7750 and Juniper MX on EVE-NG

In the previous blogs, I showed how to interop MPLS ePipe and VPRN network services between Nokia 7750 and Cisco 7200 routers on GNS3 (http://www.gns3.com) on a Windows PC. In this blog, I will show how to config and verify Nokia 7750 and Juniper MX routers for MPLS VPLS (Virtual Private LAN Service) network service interop … Continue reading MPLS VPLS Interop – Nokia 7750 and Juniper MX on EVE-NG

MPLS VPRN (L3 VPN) Interop – Nokia 7750 and Cisco 7200 on GNS3

In the previous blog, I showed how to interop Nokia 7750 and Cisco 7200 with MPLS ePipe Pseudo Wire service all on a PC running GNS3. RSVP-TE and TLDP are used as the signalling protocols to establish the MPLS Transport and Service Tunnels respectively for the MPLS ePipe service. Since ePipe is a layer 2 network … Continue reading MPLS VPRN (L3 VPN) Interop – Nokia 7750 and Cisco 7200 on GNS3

MPLS Pseudowire ePipe Interop – Nokia 7750 and Cisco 7200 on GNS3

Not long ago, network equipment testing involves a lot of coordination with your colleagues to share and wire up the equipment in the lab before any testing can be started. With the popularity of network virtualization, all major vendors now offer virtualized version of their equipment in one form or another and many simple network equipment testing … Continue reading MPLS Pseudowire ePipe Interop – Nokia 7750 and Cisco 7200 on GNS3
