Preseem now supports IPv6

Features

IPv6

Preseem now supports IPv6 for all use cases. This includes the ability to assign subscribers a prefix of arbitrary length.

IPv4 with Prefixes of Arbitrary Length

Previously Preseem modelled subnet assignments to customers as a number of /32 assignments. For example a subscriber who was assigned a /30 would result in four internal /32 mappings. Preseem now supports assigning any prefix length to a subscriber without expanding these into /32 entries internally.

Preseem and Switches in switch centric design

Anyone who follows me knows I am a big fan of switch centric designs. This usually involves a router on a stick paired with a high port count switch. Recently I had a client that installed a Preseem appliance in their network.

Equipment used in this setup
-Dell R710 with a 4 Port SFP+ card running Preseem
-Cisco 3064-X 48 Port switch
-Maxxwave Vengeance router with dual QSF+ card and 4 Port SFP+ card

A visio diagram of how this looks

We have two transport links coming into the switch on the left. These are dumped into VLANs 506 and 507. We then come out of the switch into the Preseem box via 2 SFP+ ports, one for each VLAN. In this case, we just used DAC cables In the future, we can turn these into trunk ports to pass more VLANS through.

The data then leaves the Preseem box over dual SFP fibers directly into the router’s SFP+ ports. If the Preseem appliance fails we have a secondary OSPF/IBGP path from the router’s 40 GIG QSFP down to the switch. This is a bypass in case the Preseem appliance hardware fails.

If you start flowing more than 10 Gigs through a single link you can upgrade to more SFP+ ports into your appliance and a 40 Gig QSFP+ card. You then link the appliance to the spare QSFP port on your router.

j2 Podcast:5g hype, more bandwidth, preseem

Hi this is Justin, it’s Tuesday, July 30th, 2019 and this is the ISP news you need to know.  It’s been quite hot in my office so I haven’t been doing many recordings due to fans and such making it noisy in here.  here are some of the things you need to know.

Think 5G is all hype?

Preseem releases access point paper

https://www.preseem.com/2019/06/wireless-access-point-market-insights/

Unlike spec sheets from manufacturers, Preseem collects real-world data from access points in all kinds of deployments and analyzes statistics at a top level to offer valuable insights. So, as part of our Fixed Wireless Network Report, we calculated wireless access point market insights on market share, connected subscriber count, performance on QoE metrics like latency and much more…
