Reston, VA -- Isocore, the technology validation leader in
next-generation IP and optical networking, today announced the
successful completion of its Fall Leading Edge Code testing event at
which leading vendors from the MPLS, GMPLS, and optical industry
participated.
Vendors participating in the IP/MPLS Leading Edge Code testing
included Agilent (NYSE:A), Alcatel (Paris: CGEP.PA, NYSE: ALA), Avici
Systems (NASDAQ: AVCI), Chiaro Networks, Cisco Systems (NASDAQ: CSCO),
IXIA (NASDAQ: XXIA), Juniper Networks (NASDAQ: JNPR), Redback Networks
(NASDAQ: RBAK), and Spirent Communications (NYSE: SPM). Vendors
participating in the IP-Optical/GMPLS Leading Edge Code testing
included Agilent (NYSE:A), Avici Systems (NASDAQ: AVCI), Cisco Systems
(NASDAQ: CSCO), Fujitsu , Juniper Networks (NASDAQ: JNPR), Spirent
Communications (NYSE: SPM), and Sycamore Networks (NASDAQ: SCMR), and
on-site participation and support by KDDI R&D Laboratories, Inc. and
NTT. |

For the first time in the industry, vendors successfully demonstrated
the delivery of true IPTV solutions across Multicast Layer 3 VPNs (MVPN)
and Virtual Private LAN Services (VPLS), thus maintaining a Quality of
Experience (QoE). Multi-vendor interoperability of IPv6 VPNs across a
fully resilient IPv4 MPLS core was demonstrated to highlight IPv6/IPv4
inter-working for next-generation networks. Triple play services
demonstrated delivery of IPTV, VoIP and Data over a converged network.
Edge devices were tested for IGMP Join/Delay measurements, scaling up
to 100 IPTV channels across the MVPN using PIM-SM and VPLS with IGMP
snooping on the access with set top box emulation. In the IPv4 core,
state-full failover resiliency mechanisms were verified for RSVP-TE
and LDP fast reroute. E-LSPs (Label switch paths carrying several
class types and PHB associated with EXP bits) were setup across LSP
hierarchy and GMPLS enabled optical core. Over 200 simultaneous VoIP
calls were simulated over these LSPs and MOS measurements made to
verify call quality.
Interoperability validation at the optical layer demonstrated
compliance to standardized GMPLS addressing and constraint based path
computation (i.e., CSPF). For the first time, an attempt was made to
evaluate the GMPLS UNI proposals for Layer 1 VPN realization currently
being developed in the Internet Engineering Task Force (IETF) and
successful GMPLS UNI with Ethernet over SONET was tested. The event
verified MPLS to GMPLS migration strategies by demonstrating advanced
MPLS-based Layer 2 VPLS services and Layer 3 VPN (supporting IPv6
customers) carrying IPTV and multicast triple play services across
IP-Optical transport network enabled by using Standards-based GMPLS
control plane protocols. In addition link management protocol (LMP),
OIF-UNI and GMPLS interworking scenarios were also tested.
The results of these testing and other on-going efforts at Isocore
Internetworking Lab will be presented at the 6th Public
interoperability demonstration to be held on October 20 following MPLS
2005 (www.mpls2005.com) at Isocore.
