Benefits
Intelligent Multilayer Gigabit Ethernet Switch
ZyXEL GS-4000 Series is an intelligent Gigabit multilayer (L2/L3/L4) Ethernet switch that provides
enterprise-class availability, resilient and redundant architecture with OSPF, VRRP, RSTP and port trunking.
The GS-4000 Series offers many advanced features to make it the preferred choice for real-routing network
in the enterprise. Advanced functionalities like QoS, rate-limiting, rule-based access control lists,
multicasting support, wire-speed, high-performance IP routing and simplified management software
(iStacking) highly improve network operation.
High-Performance Wire-speed Switching and IP Routing
The GS-4000 Series consists of two switches: the GS-4024 with 20-port 100/1000BASE-T RJ-45 and four dual-
personality GbE interface (RJ-45 or SFP), the GS-4012F with 8-port SFP open slots and four dual-personality
GbE interface (RJ-45 or SFP). Base on non-blocking switching architecture, the GS-4000 Series can be
deployed as both an intelligent access layer switch for enterprise wiring closets and as a Layer 3 backbone
switch for SMB networks.
The GS-4000 Series delivers wire-speed full-dynamic IP routing, like OSPF and RIP using a hardware-based IP
routing engine and sophisticated multilayer operating software. In addition to dynamic IP multicast, the GS-
4000 Series supports Distance Vector Multicast Routing Protocol (DVMRP) and Internet Group Management
Protocol (IGMP) snooping to perfectly handle a variety of datagrams making the ZyXEL GS-4000 Series ideal
for today's multi-service network environment.
iFlow - Advanced QoS for Significant Service
The GS-4000 Series works with ZyXEL exclusive iFlow technology, a set of advanced QoS mechanisms,
to insure noteworthy service, and smooth operation via a series of QoS processes to prevent customers'
networks being negatively impacted by network congestion. With intelligent multilayer capability, the GS-
4000 Series offers wire-speed flow control which can classify, police, and prioritize the incoming packets
according to predefined QoS policies. In classification, Differentiated Services Code Point field (DSCP) and
the 802.1p class of service (CoS) field are identified to assess the priority of incoming packets. Classification
and reclassification can be based on criteria as specific as rule-based on IP, MAC addresses, VLAN ID,
TCP/UDP port number, on the other hand, for bandwidth management, the GS-4000 Series is loaded with
powerful traffic management tools. For instance, the GS-4000 Series provides eight priority queues per port
for different types of traffics, allowing administrators to set rule-based rate limiting which takes full
advantage of limited network resources and guarantees the best performance.
