Network Structure in Juniper eye

Bkjia.com comprehensive report] traditional network infrastructure has always adopted a tree structure. the inherent complexity of this architecture greatly limits the performance and scalability required by cloud computing and other IT systems. Therefore, Juniper has been committed to operating multiple devices in the form of a single logical device, thus flattening the network structure and realizing the advantages of such a network architecture.

As a leader in high-performance networks, Juniper has been engaged in this research for more than five years and has used its TX Matrix router and the latest TX Matrix Plus, A maximum of 16 T series vrouters can be connected to a single routing device.

In addition, Juniper can implement high-speed internal connections up to 128 Gbps for users through its cluster switching technology. In addition, up to 10 EX4200 switches can be connected to each other and run as a single logical device.

Layer 3 to Layer 2

Juniper can apply the cluster switching technology to the storage layer of the data center network, so that the traffic between servers in the switching matrix can be directly transmitted from the east to the west using a one-way path, reducing the latency.

Since Juniper has restricted the traffic to the access layer, it can reduce the number of expensive uplinks.

Then, a high-density 10 Gbit line rate switch (such as EX8200) is used to interconnect the configuration of cluster switching, which can effectively eliminate the aggregation layer and flatten the network, and reduced the network level to two layers.

It can be seen that the cluster exchange technology naturally has three major advantages:

1. Low latency: The Juniper cluster exchange technology can directly transmit traffic from the east to the west, thus reducing the latency of Juniper products by 68% to 85% compared with competitors.

2. Simpler: When the storage layer has cluster switching technology, you only need to manage a single Switching Matrix, instead of managing up to 10 individual switches. Juniper can also help reduce the number of interactions between vswitches, which can be reduced by up to 99% ).

3. Low Cost: After the network architecture becomes simpler and flat, the number of switches required will be reduced, and the cost will be greatly reduced. Customers who use Juniper solutions and products can reduce their capital expenditures by up to 35%. In addition, the customer's cost in power consumption, space, cooling, maintenance and management is also reduced. In fact, according to industry analysts, when the number of network layers is reduced to two layers, the flat network can help reduce the cost of data center networks around the world by up to $1 billion.

Taking 1,000 ports as an example, after the customer uses the cluster switching technology, the number of devices managed will be reduced by 83%, and the number of interactions will be reduced by 97%. Therefore, the more online devices a user has, the more benefits the user has.

Juniper has been studying two-tier networks since two years ago, while other vendors have realized the benefits of two-tier structures only now. However, Juniper will not stop moving forward. Just as Juniper has always been a pioneer in innovation in the industry. At present, a new layer-1 network structure has been developed, which is the ultimate goal of the cloud planning Project Stratus.
