Handles network connections and hosts multiple services with automation

Juniper Contrail Networking is designed to streamline and integrate networking solutions within OpenStack environments. While Juniper's strategy initially aimed at enhancing system integration, some users have reported challenges with seamless integration, with other platforms like Red Hat and Ubuntu. These integration issues sometimes led to difficulties in diagnosing problems, as they were attributed to Contrail or OpenStack rather than directed to the appropriate support channels. Additionally, concerns were raised about the complexity of involving networking components like MX routers, which often required expertise beyond the scope of software engineers. As a result, users encountered challenges in achieving comprehensive understanding and troubleshooting of networking issues within the Contrail environment.

Session-based routing has reduced WAN costs and delivers faster failovers with app-aware paths

The best features of Juniper Session Smart Router that offer me value are the ones I use daily, including session-based routing and core features that route traffic per session instead of tunnels, giving better performance, seamless failovers, and application-aware path selection. It selects the best link, whether MPLS, broadband, or LTE. It also has built-in zero-trust security which means it controls segmentation without needing a separate VPN setup and advanced visibility and analysis, providing strong insight into traffic, session, and performance. This provides simple branch management. Juniper Session Smart Router has positively impacted my organization by achieving a 30% to 40% reduction in WAN cost, which means less reliance on MPLS. There is also a 40% faster failover with near-zero user impact during link issues, and 20% to 30% less time spent on troubleshooting. Additionally, I experience fewer outages due to dynamic path selection, which facilitates fast branch deployment.

Quotes from Members

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

Pros

"Juniper Contrail Networking is a stable solution."

"Contrail automates the excellent communication between virtual appliances."

"It provides proactive alerting in a single dashboard solution."

"Juniper Contrail Networking is low-cost for small and medium-sized businesses, and Cisco and Palo Alto solutions are more expensive."

"After we finished setting Contrail up, it seemed stable enough. Still, we never tested it in a real environment, so we don't have enough information to say whether it's stable with a given number of users and appliances. We have tested it in a lab environment, but we haven't tested enough to say that the platform is stable."

"After we finished setting Contrail up, it seemed stable enough."

"Because we are talking directly to engineers in the US, the support is usually the best you can possibly get."

"Juniper Session Smart Router has positively impacted my organization by achieving a 30% to 40% reduction in WAN cost, which means less reliance on MPLS, with a 40% faster failover with near-zero user impact during link issues, and 20% to 30% less time spent on troubleshooting, along with fewer outages due to dynamic path selection, which facilitates fast branch deployment."

"The solution is especially Session's smart, application-aware, AI-based."

"They provided us with a customized product according to our requirements."

"Customer service is very prompt."

"As compared to the other major vendors in the SD-WAN market, such as VeloCloud, Cisco, and others, the tunnel-free and secure vector routing technology is its major USP, which gives plenty of room to discuss with the customer why IPSec from 1998 is a bit outdated."

"The best feature is the easiest way to deploy configuration and also back up them, and also to roll back quickly if there's an incident."

"For telecom companies, I think zero-trust segmentation is the way to go because if you allow anything that you do not understand, then it becomes a problem."

Cons

"Concerns were raised about the complexity of involving networking components like MX routers, which often required expertise beyond the scope of software engineers. As a result, users encountered challenges in achieving comprehensive understanding and troubleshooting of networking issues within the Contrail environment."

"Juniper needs to address the market's specific requirements, such as the SME sector, and offer more lower-priced products like a lower-end segment switch."

"Visibility, especially for the top of the platform, is a nightmare. The top was documented incorrectly and really complex to complete. In the end, it worked but only after several weeks of work with the support of a Juniper solution engineer in Holland."

"Juniper Contrail Networking is difficult if you do not have a certificate for Juniper. Juniper is a different type of configuration or operation than Cisco."

"Visibility, especially for the top of the platform, is a nightmare. The top was documented incorrectly and really complex to complete."

"Juniper Contrail Networking is difficult if you do not have a certificate for Juniper. Juniper is a different type of configuration or operation than Cisco."

"Juniper Session Smart Router could improve its documentation to become more competitive. It has very little documentation, and you have to rely mainly so much on support to do something, which I feel should not be that way."

"I found some weaknesses on their hardware. They are sometimes breaking very often."

"The UI of the SSR conductor is the main part where improvements can be done. Today, for every configuration step, you have to do a series of clicks. What we are missing there are wizards. For example, I have two applications, and I want one application to be prioritized against the other. In such a case, a wizard for assigning policies to a service without configuring each step by hand would be very helpful. There should be an overhaul of the GUI of the conductor. The functionality they have got in the Mist portal should be baked into the conductor itself. It would be really great, but as we all know, that won't happen."

"Juniper Session Smart Router could be better in several areas such as the steep learning curve because the session-based model is different from traditional networking."

"Regarding improvement, we still need to see what it can do."

"The UI of the SSR conductor is the main part where improvements can be done. Today, for every configuration step, you have to do a series of clicks."

"Juniper Session Smart Router can improve the integration for Wi-Fi devices and add additional Sassy deployments."

"Juniper Session Smart Router could be better in terms of software performance."

Pricing and Cost Advice

"Juniper Contrail Networking is low-cost for small and medium-sized businesses. Cisco and Palo Alto solutions are more expensive."

"There are many vendors in the wireless market that offer better pricing, solutions, and management skills compared to Juniper."

"It is a simple bandwidth-based license and the orchestration comes bundled with the solution by default."

"We are currently renegotiating the offer for the licenses and the license bundle model. The license for an ISP has to be different from the license for an end customer. This is something we are currently renegotiating with Juniper, but, of course, the pricing for the licensing is always an issue when you want to get more customers."
