Ethernet over Copper for Access to VPLS and MPLS Networks
Ethernet over Copper access does not require fiber. But this technology offers excellent scalability for VPLS and MPLS network and Internet access. For the full year 2012, the global Ethernet access device (EAD) market grew 3.5 per cent, to $860 million, with growth slowing as a result of the economy and a drop in carrier spending. “People […]
Why does packet loss seriously hurt application performance over the WAN? How do we address it?
TCP was never optimized for high-bandwidth WANs or interactive applications over the WAN. Packet loss has the greatest impact on the applications performance over the WAN, by design. Why is packet loss such a killer? There are many reasons, most having to do with the nature of how TCP was designed especially how TCP does congestion control/congestion avoidance. The […]
Bursting on an MPLS or VPLS Network
A handful of carriers support bursting on their IP-VPN networks. Bursting can provide a real cost savings benefit to customers. First, it’s a solution for customers who don’t how much bandwidth they need at a given location. Bursting lets these customers add locations to their network at the lowest level of cost commitment. Second, it […]
Why consider VPLS for your WAN
More flexibility and manageability with with VPLS When it comes to rapid change and advancement, companies which can respond quickly to market shifts will benefit from VPLS, a Virtual Private LAN Service (VPLS) solution.

Prices for wholesale IP transit service continue to decline throughout the world. According to new data from TeleGeography’s IP Transit Pricing Service, price declines in most locations accelerated between Q2 2011 and Q2 2012, compared with the longer-term trend. These trends will reduce the cost of local loop or tail-circuits for wide area networks and internet […]
Troubleshooting VPLS and Ethernet Tunnels over MPLS
LSP ping has limited efficiency in troubleshooting both VPLS and point-to-point Ethernet tunnels over MPLS. There are a number of reasons: 1. Ethernet P2P or VPLS is implemented on an additional layer over the LSP; and that is referenced as a psuedowire or Martini tunnel.This additional layer has its own headers and ID. In addition, the psuedowire […]
Bandwidth Demand for International Circuits Grows by 45%
Data from TeleGeography’s Global Bandwidth Research Service reveal that demand for international bandwidth grew 45 percent in 2011, and at a compounded rate of 57 percent annually between 2007 and 2011. Although growth has slowed since 2008, when network capacity increased nearly 70 percent, the pace remains brisk, with aggregate capacity requirements more than doubling every two […]
