Ethernet's flexibility, cost effectiveness, and proven interoperability, along with a continuous stream of enhancements have made it a widely adopted form of connectivity -- from data centers and peering at Internet exchange points to the growing trend of metropolitan Ethernet access. The Juniper Networks portfolio of Ethernet interfaces is broad, supporting various port densities of 10/100 Fast Ethernet, Gigabit Ethernet, and 10-Gigabit Ethernet on the M-series and T-series platforms.
Key Features of the PB-4FE-TX
- Available on M40e, M160, M320, T320, and T640 platforms
- 1,024 802.1Q VLANs per port
- 100Base-T support
- Autosensing full or half duplex
Juniper Networks has further enhanced its portfolio with the advent of Ethernet Intelligent Queuing (IQ) Physical Interface Cards (PICs). These advanced PICs are based on the Q Performance Processor (QPP), a custom high-performance ASIC designed to deliver granular per-VLAN quality-of-service (QoS) capabilities along with extensive instrumentation and diagnostics on a per-VLAN and per-MAC address basis.
- Granular per-VLAN QoS such weighted round-robin, strict priority scheduling, RED, WRED, policing, marking, and shaping supports differentiated services and converged applications over a single interface, without compromising performance.
- MAC policing and filtering enables providers to establish peering arrangements without complex routing configurations and also supports additional levels of QoS enforcement.
- VLAN rewrite, tagging, and deleting enables flexible use of VLAN address space to support more customers and services.
- Extensive per-MAC and per-VLAN billing and accounting capabilities are supported by multiple counters for gathering statistics on frames, packets and bytes that are transmitted, received, or dropped, enabling carriers to perform usages based billing for premium QoS and SLA-based services and to provide the visibility needed into network operations to ensure that trends are anticipated to meet increasing demands.
