Juniper NETWORKS 3.4.0 Juniper Address Pool Manager хэрэглэгчийн гарын авлага

Juniper Address Pool Manager (APM) is a cloud-native, container-based application running on a Kubernetes cluster that manages address pools in a network.
APM monitors the IPv4 address pools on broadband network gateways (BNGs) in the network.

When the free address utilization drops below a specified threshold on a BNG, APM adds unused prefixes from a centralized pool to the BNG’s address pool.
APM, in cooperation with the BNG, monitors and links address pools in support of dynamic address allocation mechanisms for subscribers.

APM-ийн ашиг тус нь дараах байдалтай байна.

Хаягийн ашиглалтын үр ашгийг сайжруулна

Хяналт, хангамжийг автоматжуулснаар хяналт, хангамжийн нэмэлт зардал, нарийн төвөгтэй байдлыг багасгадаг.
Дутуу ашиглагдаагүй угтваруудыг шаардлагатай усан сангуудад дахин хуваарилах боломжийг олгодог.
Enables APM to work with the BNG CUPS Controller.
These release notes accompany Juniper Address Pool Manager Release 3.4.0

Суурилуулалт

Address Pool manager 3.4.0 installation requires the minimum system requirements listed in this section.
ЖИЧ: The system requirements listed in Table 1 on page 2 are for a single geographically located installation of Address Pool Manager (APM).
For the system requirements of a multiple geographically located, multiple cluster setup, see Address Pool Manager Installation Guide.
APM installs on a Kubernetes cluster comprised of physical or virtual machines (VMs).
APM has been qualified against the single geographical cluster described in Table 1.
For information on how to install APM, see Address Pool Manager Installation Guide.

Кластер

A single cluster with 3 hybrid nodes.

Kubernetes node

The Kubernetes nodes require the following:

• For the operating system, you can use either of the following:

• Ubuntu 22.04 LTS (for a BBE Cloud setup cluster)

• Red Hat Enterprise Linux CoreOS (RHCOS) 4.15 буюу түүнээс дээш хувилбар (OpenShift Контейнер Платформ кластерт зориулсан)

• CPU: 8 or 16 cores.

Use a 16-core node if you plan on running other applications on the cluster (such as the BNG CUPS Controller application).

• Memory: 64 GB

• Storage: 512 GB storage partitioned as 128 GB root (/), 128 GB /var/lib/docker, and 256 GB /mnt/ longhorn(application data

• Kubernetes role: Control plane etcd function and worker node

This specification establishes a cluster that can run APM as well as its companion applications, such as BBE Event Collection and Visualization, and BNG CUPS Controller simultaneously.

Нэмэлт шаардлага

The BNG is a Juniper Networks MX Series router running Junos or a Juniper BNG CUPS Controller (BNG CUPS Controller).

We recommend the following releases:

Junos OS Release 23.4R2-s5 or later
BNG CUPS Controller 24.4R1 or later
For APM, confirm that you have a juniper.net user account with permissions to download the APM software package.
Download and install the APM software from a machine that will not be part of the Kubernetes cluster.

Шинэ болон өөрчлөгдсөн онцлогууд

We have introduced the following new feature in APM 3.4.0.
Support for geographic redundancy—Address Pool Manager can maintain continuous operation across multiple geographically distributed Kubernetes clusters.
By utilizing a multiple cluster architecture managed by Karmada for orchestration and Submariner for inter-cluster networking, APM can failover if a data center outage тохиолддог.

Deleting an entity-match entry does not completely clean up the show apm entity output. PR1874241
An in-service upgrade of the BBE-observer triggers a rollout. As part of an in-service upgrade of the observer microservice, it may appear as if all APM microservices are being upgraded.

The list of container images loaded or pushed in the rollout output indicates that all the microservices are being upgraded, but only the observer microservice is upgraded.
Other container images that are being loaded or pushed are not upgraded. PR1879715
Reverting network load balancer (MetalLB) annotations, followed by performing a rollout, does not reset the external IP address for the APMi.

Товчлох арга зам:

When the external address of the APMi that is bound to a particular IPAddressPool through the network load balancer annotations needs to be reverted to use an auto-assign IPAddressPool by removing the annotations, a stop command, and then a rollout command of APM must be performed.
