Enabled us to collapse hardware- and software-based solutions into one
The scalability is good for us. The 5440 HW is more than capable of handling our current traffic patterns allowing us to grow and not have to do in-place upgrades in the immediate to near term. It's meeting a small portion of our overall network needs, but provides the solution that we sought out. From a hardware standpoint, it makes up a small fraction of our overall deployment, but the usage behind it is very different from what we utilize our production data center hardware for. As I mentioned, it is just providing outbound NAT-ing for us. As we grow our data center space we would expand its usage and footprint. We typically see changes in traffic due to our organic growth and ramp-up of internal services. We plan to implement the following technologies/strategies in the next three years: keeping up with PFS/ECC encryption standards as they evolve. We may or may not move more applications to public cloud. Also, it's possible we could implement cloud repatriation of applications from public cloud to private data centers.

Routing has supported carrier-grade services and has needed more affordable security options
The features of Juniper MX Series Routers that I find most useful are its nice scalability, redundant power supply, and routing engines. Redundancy is maintained in the router itself, including power redundancy and routing engine redundancy. The routers run mostly all the protocols required for the managed service provider, and security-wise, they also have good features, allowing us to provide IPSec VPN services from the routers. These are the basic, mostly used features that we are utilizing. For Deep Packet Inspection, Juniper MX Series Routers have firewall filters and commands related to routing engine protection, and then packet inspection features are configured. In traffic management with Juniper MX Series Routers, I leverage the policer, shapers, and quality of service parameters for traffic management. I also use OSPF traffic engineering features and MPLS-TE; these are a few features that I employ for traffic management.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"It has freed up a lot of our IP space and has been extremely reliable. We have set it up in a high availability scenario, testing it many times. It has been absolutely perfect in terms of failover."
"We have absolutely seen ROI, as it saved us hundreds of IP addresses, and that's like gold."
"The most valuable features are its ease of use and deployment, and being able to collapse several solutions into a single solution, all contained within a single bit of hardware and software."
"We have been able to take a software NAT solution and a third-party hardware NAT solution and collapse them into a single solution on the A10 HW, saving us up to $250,000 by not having to purchase additional IPv4 number pools."
"It is very easy to use. Both the GUI and CLI interface are consistent, which makes the ease of access throughout various constituencies possible. It's also well-documented and logical."
"Juniper's custom Trio chipset drives their MX routers, offering superior performance. Juniper's design separates the control plane and the forwarding plane, which is a key aspect of their architecture. This separation provides high throughput, maintaining line-rate performance across the MX platform."
"The most valuable feature is the capacity of the throughput for the firewall."
"The functionality and stability are great."
"The most valuable feature is the standard routing protocol."
"Juniper is at the forefront of IT technology."
"The most valuable features for us were related to our transition into MPLS technology, specifically for BPN and VPN services."
"The product is easy to use."
"Since building out the MX-based infrastructure, our core network uptime has been consistently above 99.99%."
 

Cons

"There are a couple of features that they could look to implement, versus the workarounds that they have in place. Regarding IPv4 and IPv6, there are a couple of opportunities in there that they are working on, as well."
"They don't track concurrent port usage. We have to do that in another way and it's not a very clean way. That is something that I know they could do, but they don't."
"We had a bug with an MX104 that we tried to deploy and it kept crashing."
"The third-level customer support coming from Juniper itself could be much better. To get assistance from Juniper, we sometimes have to wait for weeks and months. I don't really appreciate that. Their support should be faster."
"Enhancing the capacity would be a welcome improvement."
"Some of our customers find this product high, as they are comparing to Chinese products."
"Juniper have addressed issues with the MX204, but it still has a limited number of interfaces. Ideally, it should support up to twenty or twenty-four interfaces to better serve smaller service providers. Additionally, the MX304 doesn't support subscriber management, also known as BNG, which I believe should be included."
"The solution could improve by providing better training to allow more sales of the solution in the market."
"One thing that the product can do better is clustering. Rather than just having two of them, it would help if there was one cluster to extend to more notes in the cluster itself."
"In terms of what could be improved, they could extend the software warranty to be for its lifetime, as well. At the moment, the software warranty is limited, I think to one year."
 

Pricing and Cost Advice

"The cost to buy it initially was a single purchase price. This was a cost for the hardware and software, but we got a year of service with it. Annually, we pay them a service fee, but it's not much money."
"The FlexPool consumption-based licensing model has the ability to spin up VMs as needed for NAT, as well as their ADC, which is their load balancing stuff. We are considering that, as that is a pretty attractive feature."
"The price of this solution is better than other competitors, such as Cisco. We receive a lot of discounts which make the price less expensive and attractive."
"$300 to $400 is the hardware cost and for licensing cost, it may be around, for support and all, $100 per year."
"The solution is more expensive compared to other solutions."
"I would rate it around a three. While I'm not deeply involved in pricing discussions, I believe it is comparatively more affordable than Cisco."
"The prices for Juniper MX Series Routers are reasonable."
"I would rate the pricing model a seven out of ten, where one is cheap, and ten is expensive. It is not cheap."
"We have to pay for the device and licensing. The support service requires additional costs."
"The pricing of Juniper MX Series Routers is okay compared to other technologies."
