[AFMUG] PTP500 firmware
Looking to upgrade my PTP500’s firmware. Is that dropbox shared firmware folder still available? Or a less than 12-month MAC? Thanks in advance, Scott sc...@velociter.net
Re: [AFMUG] ERPS: G.8032 vs Brocade MRP vs ?
Is bandwidth detection really that important? Can’t you implement port shut-down on your backhauls at/below certain modulation levels?

It’s a tough one. MEF/ITU/IEEE Ethernet standards do have a lot of the mechanisms from SONET that allows you to specify reversion time on circuits to limit damage from flapping. Performant was the only one who seems to have tried to do anything with automated bandwidth detection and making forwarding decisions. Unfortunately it’s such a niche market that I doubt there was an economic case for it. Everyone else just throws fiber and bandwidth at the problem. WISP’s have a somewhat unique problem in that it’s very easy for us to make mesh type backhaul networks yet difficult to logically segment the network at the Ethernet level. G8032.v2 attempts to solve the issue but I don’t think there is a great deal of demand from the bigger carriers for the mesh design given that bigger carriers can just throw another fiber or wavelength at the problem to segregate the network.

Josh- Did your upstream engineer find an alternative solution or pursue a new protocol? Scott From: Af [mailto:af-boun...@afmug.com] On Behalf Of Josh Reynolds via Af Sent: Monday, December 1, 2014 00:08 To: af@afmug.com Subject: Re: [AFMUG] ERPS: G.8032 vs Brocade MRP vs ? Scott, I had been talking to our upstream's primary network engineer a few weeks back. They tested G8032v2 stuff from several vendors, and ended up pulling it completely after a full year of testing. Ring topology is a pretty dead design when "mesh" type options are available with OSPF/IS-IS/MPLS. Some of the things about 8032v2 are nice, but they will also be found in SPB. What we need is for Accedian to sell the continuous-throughput-testing patent they have to another vendor. josh reynolds :: chief information officer spitwspots :: www.spitwspots.com<http://www.spitwspots.com> On 11/30/2014 09:17 PM, Scott Vander Dussen via Af wrote: Seems like the new AFMUG list scraped my PDF attachment off that last email, here's a dropbox link: https://dl.dropboxusercontent.com/u/6582330/WebJunk/ERPS_Towers.pdf Scott -Original Message- From: Af [mailto:af-boun...@afmug.com] On Behalf Of Scott Vander Dussen via Af Sent: Sunday, November 30, 2014 22:11 To: 'AF Cambium List (af@afmug.com<mailto:af@afmug.com>)' Subject: [AFMUG] ERPS: G.8032 vs Brocade MRP vs ?

Re: [AFMUG] ERPS: G.8032 vs Brocade MRP vs ?
Mark- Why Ciena > Brocade? And generally speaking, when Ciena is referring to G.8032 is that assumed it's the second revision? Their chalk talk video is clearly referencing features unique to v2, but the documentation only identifies simply "G.8032". Scott -Original Message- From: Af [mailto:af-boun...@afmug.com] On Behalf Of Mark Radabaugh via Af Sent: Monday, December 1, 2014 05:52 To: af@afmug.com Subject: Re: [AFMUG] ERPS: G.8032 vs Brocade MRP vs ? We are evaluating vendors for this at the moment. Ciena is looking like the winner at the moment, with G.8032 as the loop control topology. So far we have rejected Cisco, Juniper, Performant, Accedian, and Extreme as vendors. To answer Forrest’s question - yes, we do need faster recovery than we can get from MSTP, OSPF, MPLS. While those protocols have worked well, they don’t have the recovery time we want. Other things we are looking for beyond quick recovery time: Carrier Ethernet Services (Metro Ethernet Forum) Ethernet OAM Performance Monitoring (Y.1731) I want to be able to offer carrier type services (NNI, E-Line, E-LAN, E-Tree, E-Access) to other companies over our wireless and fiber network. If you want to sell services to cell companies they are requiring Y.1731 (Performance Monitoring) at the handoff. We already have pieces of this in place over the wireless network using Q-in-Q, but want to extend this further. We currently have one other ISP set up selling services over our wireless network with transparent (to the customer) Ethernet delivery back to the providers network. It’s pretty cool in that they can install customers anywhere on our Canopy network and deliver the Ethernet traffic back to their network. We don’t care what VLAN, IP Addressing, DHCP, or Authentication scheme they are using - it’s just Ethernet.
