Amazon (sort of) do this, which is why I cancelled their Video service
here in Johannesburg. It will show you what's in the library, but when
you play it, it will tell you that it's not available for your region.
If they could add the "commercial activism" button, I'd be okay to lose
5 seconds pressing it.

There are too many moving parts for Netflix to reliably build code that
could determine that an HE tunnel is coming from the right place content
owners mandate their media be distributed to. That code would end up
getting unwieldy, taking up too much time and becoming a full-time job.

Since Netflix are sinking more and more cash into their own content
every year, to me, that seems like a better long-term solution.

I wouldn't immediately compare all of those services to Netflix (or even

Re: Europe IP Transit Provider Ideas ?

[Darin Steffl]

Why isn't Hurricane in your mix yet? They have great routes, some of the
lowest pricing available, and they are always easy to reach at the NOC.
They also peer at nearly every IX possible. They're #1 in number of BGP
adjacencies.

It looks like they have 3 or 4 paths in/out of Africa. I'd use their
looking glass tool to check latency and peering.

For aggregation, we haven't bought Cisco switches for anything since
2014, when invested in a bunch of 3650's (they run IOS XE).

We use these purely as Layer 2 switches in low-density applications
where we need copper ports to connect to supporting services, e.g., DNS,
HTTP/HTTPS, TACACS+, RPKI, NMS, e.t.c.

We used the EX4550 for years until their buffers became too small as
customer demand for bandwidth increased. We couldn't find anything in
the Cisco stable that made sense, and Juniper's EX4600 was very strange
when they switched to the ELS Junos code. So we went with Arista's 7208R
in the data centre to replace the EX4550's.

I have no experience with Arista's IP feature set on their switches, but
I hear it is maturing slowly.

Europe IP Transit Provider Ideas ?

[James Braunegg]

Dear Nanog

For those running a AS with multiply POP locations around the world who would 
you recommend as a strong tier 1 transit provider in Europe (good routes to 
Africa would be a bonus)

We currently take full table feeds from Telia, GTT, Cogent, Retn, tisparkle 
(Seabone) we are also looking at adding NTT in the USA and maybe also in Europe 
but any other recommendations ?

Happy to be contacted by transit providers off list, thanks in advance

For Europe, even though it's 10% of our overall traffic, we have been
happy with the top 7 global carriers.

For routing into Africa, I'll unicast you.

Well, these days, with plenty of newer, affordable options coming in on
Broadcom chips, it's safe to say both hardware and software will require
a lot of maturity to be viable against "the establishment".

For Africa, Kenya and South Africa tend to be typical points for initial
build-outs. Nigeria gets attention too.

You want to look at an operator that spreads across more locations than
that to reach as many African networks as possible. The ones that I know
of have Africa as their primary market, but also have presence in Europe.

Re: Layer 3 Switches

[Kevin Burke]

+1 to the software & support

Within the last year we have learned & deployed Juniper & Extreme.  They are 
easily as good or better than the rest of the crowd.

We use Ubiquiti stuff too.  Its good on the edge, less so in the core.  They 
don’t keep a product around long enough to work the bugs out.

I've liked the price of the Ubiquiti switches I've seen, but haven't gotten
to play with them, and based on their EdgeRouter line, am not sure about
their maturity either.

A switch's maturity is much more dependent on hardware while a router is much 
more dependent on software, so I suggest assessing a switch on their own 
merits, regardless of bad experiences with that vendor in the router realm.

I'm going to kick the nest in the other direction now :D ... There
would be no need to massively scale an IGP or worry about running
LDPv4 + LDv6 or SR MPLS if we had put more development time into MPLS
over UDP. I think it's a great technology which solves a lot of
problems and I've been itching to deploy it for ages now, but vendor
support for it is nowhere near the level of MPLS over Ethernet.

Cheers,
James.

It works because SR != MPLS.

SR is a protocol which describes many aspects, such as how traffic
forwarding decisions made at the ingress node to a PSN can be
guaranteed across the PSN, even though the nodes along the PSN path
use per-hop forwarding behaviour and different nodes along the path
have made different forwarding decisions.

When using SR MPLS segment IDs are used as an index into the label
range (SRGB) and so SIDs don't correlate 1:1 to MPLS labels, equally
with SRv6 the segment IDs are encoded as IPv6 addresses and don't
correlate 1:1 to an IPv6 address. There is a venn diagram with an
overlapping section in the middle which is "generic SR" with a bunch
of core features that are supported agnostic of the encoding
mechanism.

Cheers,
James.

Re: Europe IP Transit Provider Ideas ?

[Eric Kuhnke]

For Africa take a look at Liquid Telecoms and WIOCC. If your target market
is more specifically west african, look at the ISPs which have major POPs
in Accra and Lagos.

For east africa, Kenya/Tanzania, and those with good connectivity from
Kenya to Djibouti and into the UAE (via Fujairah).

WIOCC is somewhat of an east african specialist.
