ACX1000 and ACX1100 System Overview

ACX1000 and ACX1100 Universal Metro Router Overview

The ACX1000 and ACX1100 Universal Metro Routers are principally designed to provide superior management for rapid provisioning to the access network. The ACX Series routers support rich Gigabit Ethernet and 10-Gigabit Ethernet capabilities for uplink, along with support for legacy interfaces and Gigabit Ethernet interfaces in a compact form factor that is environmentally hardened and passively cooled. Seamless, end-to-end MPLS can be used to address legacy and emerging requirements to provide the foundation for a converged network that utilizes the same mobile backhaul infrastructure for business or residential services.

The routers are single-board routers with a built-in Routing Engine and one Packet Forwarding Engine. The Packet Forwarding Engine has one “pseudo” Flexible PIC Concentrator (FPC 0). Because there is no switching fabric, the single Packet Forwarding Engine takes care of packet forwarding.

Routing Engine—Provides Layer 3 routing services and network management.
Packet Forwarding Engine—Performs Layer 2 and Layer 3 packet switching, route lookups, and packet forwarding.

The ACX Series router is powered by Junos OS, supporting extensive L2 and L3 features, IP and MPLS with traffic engineering, rich network management, fault management, service monitoring and Operation, Administration, and Maintenance (OAM) capabilities, and an open software development kit (SDK) system that allows providers to customize and integrate operations with their own management systems. For a list of related Junos OS documentation, see https://www.juniper.net/documentation/software/junos/.

As part of the mobile backhaul, the ACX Series router at the cell site and the MX Series router at the aggregation layer provide comprehensive end-to-end Ethernet, MPLS, and OAM features with the one Junos OS running on both platforms.

The compact routers are one rack unit (U; that is, 1.75 in., or 4.45 cm) tall. Several routers can be stacked in a single floor-to-ceiling rack for increased port density per unit of floor space.

The chassis is a rigid sheet metal structure that houses all the other router components. The chassis measures 1.75 in. (4.45 cm) high, 9.4 in. (24 cm) deep, and 17.5 in. (44.5 cm) wide. The outer edges of the mounting brackets extend the width to 19 in. (48 cm) (from the front-mounting brackets to the rear of the chassis). The chassis installs in standard 300-mm deep (or larger) enclosed cabinets, 19-in. equipment racks, or telco open-frame racks.

Benefits of the ACX1000 and ACX1100 Routers

Space efficiency—Conforming to the ETSI 300 specifications, the ACX1000 routers are easy to deploy in environments where rack space and cooling are limited.
Improved operational efficiency with zero-touch deployment (ZTD)—The ACX Series routers support a zero-touch deployment (ZTD) model that significantly reduces the time for any new equipment installation and provisioning, resulting in improved operational efficiency.
Installation flexibility with an environmentally hardened design—Most ACX Series routers are temperature hardened and support passive cooling for outdoor deployments in extreme weather conditions.

ACX1000 Router Description

The ACX1000 routers contain eight T1/E1 ports and twelve Gigabit Ethernet ports, eight of which are RJ-45 ports. The ports labeled COMBO PORTS provide an additional four RJ-45 ports or four Gigabit Ethernet SFP ports. You can use only one set of combination ports at a time.

Figure 1 and Figure 2 show the front and rear views of the ACX1000 router.

Packet Flow on ACX Series Routers

The class-of-service (CoS) architecture for ACX Series routers is in concept similar to that for MX Series routers. The general architecture for ACX Series routers is shown in Figure 7.

Figure 7: ACX Series Router Packet Forwarding and Data Flow

Based on the model, ACX Series routers contain a built-in Routing Engine and Packet Forwarding Engine and can contain both T1/E1 and Gigabit Ethernet Ports.

The Packet Forwarding Engine has one or two “pseudo” Flexible PIC Concentrators. Because there is no switching fabric, the single Packet Forwarding Engine takes care of both ingress and egress packet forwarding.

Fixed classification places all packets in the same forwarding class, or the usual multifield (MF) or behavior aggregate (BA) classifications can be used to treat packets differently. BA classification with firewall filters can be used for classification based on IP precedence, DSCP, IEEE, or other bits in the frame or packet header.

However, the ACX Series routers can also employ multiple BA classifiers on the same physical interface. The physical interfaces do not have to employ the same type of BA classifier. For example, a single physical interface can use classifiers based on IP precedence as well as IEEE 802.1p. If the CoS bits of interest are on the inner VLAN tag of a dual-tagged VLAN interface, the classifier can examine either the inner or outer bits. (By default, the classification is done based on the outer VLAN tag.)

Eight queues per egress port support scheduling using the weighted deficit round- robin (WDRR) mechanism, a form of round-robin queue servicing. The supported priority levels are strict-high and default (low). The ACX Series router architecture supports both weighted random early detect (WRED) and weighted tail drop (WTD).

All CoS features are supported at line rate.

The packet pipeline through an ACX Series router is shown in Figure 8. Note that the rate limiting is done with an integrated architecture along with all other CoS functions. Scheduling and shaping are supported on the output side.

Protocols and Applications Supported by ACX Series Routers

Table 3 contains the first Junos OS Release support for protocols and applications on ACX Series routers. A dash indicates that the protocol or application is not supported.

Note:

The [edit logical-systems logical-system-name] hierarchy level is not supported on ACX Series routers.
The ACX Series routers does not support per-family maximum transmission unit (MTU) configuration. The MTU applied to family inet gets applied to other families as well, even though it can be configured though CLI and visible in show interface extensive output. The only way to use higher MTU for a family is to manipulate the MTU, apply at interface or family inet levels, and let it calculate for each family automatically. MTU values are not limited to 1500 but can range between 256 to 9216.
