IP DSCP across the Internet
by Ramy Hashish 08 May '15

Good day all, A simple question, does Internet trust IP DSCP marking? Assume two ASs connected through two tier 1 networks, will the tier one networks trust any DSCP markings done from an AS to the other? Thanks, Ramy

Huawei and ZTE Routers
by Colton Conor 08 May '15

08 May '15

The other thread about the Alcatel-Lucent routers has been pleasantly delightful. Our organization used to believe that Juniper, Cisco, and Brocade were the only true vendors for carrier grade routing, but now we are going to throw Alcatel-Lucent into the mix. ZTE and Huawei, the big chinese vendors, have also been mentioned to us. I know there are large national security issues with using these vendors in the US, but I know Level3 and other large American vendors use Huawei and ZTE in their networks. How do their products perform? How are they compared to Cisco and Juniper on the performance side of the house? Is their pricing really half or less of that of Cisco and Juniper? Is it worth using these vendors or not worth the hassle?

There was an inadvertent DMARC handling setting applied to all posts. This has been corrected. Sorry for the disruption. Andrew Koch

Alcatel-Lucent 7750 Service Router (SR)
by Colton Conor 08 May '15

08 May '15

I was wondering if anyone was using a Alcatel-Lucent 7750 Service Router (SR) in their network? How does this platform compare the the Cisco ASR, Brocade MLXe, and Juniper MX line?
