MS4000 Datasheet - PacketFront Network Products

MetroStar 4000 - DatasheetProduct OverviewThe MS4000 is a Layer 2 access switchdesigned for network edge service control,network aggregation with high-performanceswitching and traffic classification andprioritization to deliver the ultimate userexperience.The MS4000 provides network operators,service providers, city networks, as well assmall and medium sized companies, with aversatile tool for their switching needs. TheMS4000 capability to prioritize and allocatebandwidth fairly between applications providemaximum throughput and responsiveness forservices even when used by many users at thesame time.The MS4000 is filled with features to delivervoice, video and data services and builds on theexperience of over 1,000,000 deployed fiberto-the-homeports of previous generationswitches from PacketFront.The MS4000 can be used in a variety ofnetwork topologies such as• Customer VLAN topology in combination witha Service Router with efficient multicastdistribution and optional RADIUS basedcontrol of ingress traffic,• Service VLAN topology where the MS4000performs service enforcement and a secureMACFF based network• TR-101 topologies with VLAN translation.The MS4000 can even perform PPPoEIntermediate Agent operation to support a mixof DHCP and PPPoE based services on thesame infrastructure.Security features such as IP strict clients canbe used with both dynamic and staticallyassigned addresses to prevent spoofing of IPtraffic.Extendable through the ScriBOS scriptlanguage, the MS4000 behavior can be easilyadapted to fit into a variety of serviceprovisioning solutions using e.g. DHCP orRADIUS to signal service parameters. Industrystandard CLI and SNMP support allows easymanagement and control of MS4000 operation.The MS4000 is available in two models; eitherwith 24 RJ-45 copper (MS4126) or 24 SFP(MS4026) Gigabit Ethernet portsBenefitsAdvanced traffic classification andforwardingThe MS4000 switch silicone has extensivetraffic classification support. The networkprocessor architecture of the MS4000 allowsfurther classification and forwarding usingadvanced algorithms based on Weighted FairQueuing (WFQ) scheduling and shaping. Trafficin both ingress and egress direction can behandled through the NPU in order to overcomethe traditional limitation of hardware queuesand switch silicone rate-limiting. The MS4000performs ingress and egress shaping of trafficresulting in a fair distribution of traffic betweenapplications and flows so that a single sessionor user cannot monopolize the bandwidth of aservice and block all other applications orservices.Fair allocation of traffic is fundamental to asatisfactory end user experience. Even whenend users consume all available bandwidth,applications remain responsive.Multi-rate supportThe SFP ports of the MS4000 support both100 Mbit/s and 1 Gbit/s speeds, which meansthat upgrading access to a fiber network iseasy. In an existing Fast Ethernet network theCustomer gateway (CPE) can continue tooperate at 100Mbit/s when the access switchesare upgraded to the MS4000. Instead of forkliftupgrading all CPEs, each customer canobtain higher speed services when needed. Asimple reconfiguration in the MS4000 instantlyprovides 1 Gbit/s link speed if multi-rate SFPsare used.The 10Gbit/s ports also support 1Gbit/soperation and is fully compatible with both SFPand SFP+ optical modules.Customer and Service VLANtopologiesThe MS4000 can be used in a wide variety ofnetwork topologies and supports:• Ethernet wholesale with C-VLAN and S-VLAN,supporting double-tagging• Customer VLAN topologies with a centralService Router• Service VLAN topologies using DHCPsnooping for end-user and network securityCopyright © PacketFront Network Products AB.
