Any recommendations for FXS/FXO hardware with Cisco Unified CME
by Joel M Snyder 11 Feb '15

11 Feb '15

Folks: Since a lot of NSPs are also in the VoIP business, I was wondering if anyone has specific recommendations for low-density (2-8 ports) FXS/FXO hardware that they are using with Cisco PBX devices. (And I guess T1/E1 as well.) I know that typical IOS boxes can take modules/interfaces/whatever to handle FXS/FXO/T1/E1, but I'm trying to put some electrical distance between the Cisco PBX and the phone company to keep environmental problems (lightning, mostly) from blowing up the PBX. Cisco themselves seem to have cancelled almost all of their low-end hardware, leaving us with Sipura/Linksys. I have had good results with Audiocodes+Asterisk, but not in the Cisco PBX environment. Does anyone have boots-on-the-ground knowledge of good analog gateway choices that play very nicely with Cisco PBX? jms -- Joel M Snyder, 1404 East Lind Road, Tucson, AZ, 85719 Senior Partner, Opus One Phone: +1 520 324 0494 jms(a)Opus1.COM http://www.opus1.com/jms

IPv6 allocation plan, security, and 6-to-4 conversion
by Eric Louie 10 Feb '15

10 Feb '15

I'm putting together my first IPv6 allocation plan. The general layout: /48 for customers universally and uniformly /38 for larger regions on an even (/37) boundary /39 for smaller regions on an even (/38) boundary A few /48's for "internal use" to allow us to monitor and maintain systems. For security sake, do I need (am I better off) to "reserve" a "management block" (/39, /40, /41 or something of that nature) that does NOT get advertised into BGP to my upstreams, and use that for my device management and monitoring address space? In other words, make a small "private" address space for management? What are folks doing around that? If I have to do 6-to-4 conversion, is there any way to do that with multiple diverse ISP connections, or am I "restricted" to using one entry/exit point? (If that's true, do I need to allocate a separate block of addresses that would be designated "6 to 4" so they'd always be routed out that one entry/exit point?)

Need recommendations for high-feature, high-density L3 Switch
by Cliff Bowles 10 Feb '15

10 Feb '15

We have some aging infrastructure and need to start budgeting next-gen. * The network has several small routers as individual edges to peers, WAN, SIP services. * It has a couple 6509s as Internet edge (full tables, 2 carriers, no transit, simple policies) * It has some Nexus 7K as an aggregation layer for all the server pods * It has some 6509s as a backbone to interconnect the aggregation layers and inter-site links. * We do run VRFs/MPLS across our backbone with L3, L2 and L1 services. Nothing super fancy, but it's a requirement. Two approaches: 1 - Look at ASR9010 (or something similar) to replace all of the above. Pros: It has the density, it has features, port buffers, seems to have good granular virtualization, seems to have a good reputation amongst heavy users. Cons: It is very expensive fully populated and there is some oversubscription on the higher-density cards. 2 - Look at one solution to consolidate all edge routers and a separate solution to consolidate backbone/aggregation. Pros: Less density required at the edge layers, so a cheaper solution is possible; Not requiring full BGP tables and port buffers at the backbone/agg layer widens the selection a LOT considering the number of vendors with high-feature/high-density L3 switches. Cons: Now we are looking at 4 boxes per data center rather than 2. So... Is there something in the same class as the ASR9000s that also have a good reputation? Will need at least 48 ports of 10G, 24x1Gb, limited oversubscription, good feature sets, not astronomically priced. If we can't find the perfect fit, we will just look at two separate solutions. Also... has anyone used a CSR1000v or Vyatta VM-based solution on something like a Pluribus? I know you can run them on any server, but there are vendors like Pluribus who integrate the server hardware with a full-feature physical switch. (Their E68 is the one we are considering) I'm assuming you aren't going to get anywhere near the features and performance of an ASR9010, but... can you get close? Thanks. CWB

Any suggestions on what to tell ATT to get IPv6 added to a current account and upgrade a 2wire router to 4wire with halfway decent performance and capability? Any and all help would be appreciated. Tom

[request]: host a probe for v6 measurements
by Bajpai, Vaibhav 09 Feb '15

09 Feb '15

Dear NANOG, We are currently looking for volunteers in US with native IPv6 lines to help us in our v6 measurement research. <——------ Background We are interested in measuring IPv6 performance from home. As part of the LEONE project [1], we have developed measurement tests that compare performance over IPv4 and IPv6 to: a) Dual-stacked websites and b) YouTube content delivery network (in collaboration with Aalto University). The tests comes bundled with a LEONE SamKnows probe. [1] http://www.leone-project.eu We currently have ~25 Vantage points (VP). Each VP runs a Leone SamKnows probe. The google map [2] shows where these probes are deployed. As you can see the VP sample is too small (nothing in North America) [2] http://goo.gl/TL4woP <——------ Request: If you receive native IPv6 at home (or know someone who does), it would be great if you can host a LEONE SamKnows probe for us. The probe will run standard SamKnows tests [3] and our IPv6 tests. [3] https://www.samknows.com/tests-and-metrics We prefer measuring from home networks, but are also open to deploying probes within research/academic networks, business lines, or operators labs. <-------- Action: Let me know if you’re interested, and I can share details on how to get the probe to you. We only have limited number of LEONE SamKnows probes. We will process the requests on first come first serve basis. <-------- Research Impact. a) Measuring YouTube from Dual-Stacked Hosts Saba Ahsan, Vaibhav Bajpai, Jörg Ott, Jürgen Schönwälder Passive and Active Measurement Conference (PAM 2015), New York, March 2015. b) Measuring TCP Connection Establishment Times of Dual-Stacked Web Services Vaibhav Bajpai, Jürgen Schönwälder 9th International Conference on Network and Service Management, (CNSM 2013) Zürich, October 2013. 8<——-- Thanks. Thank you so much for helping us in our research activity.
