Race Communications presents Cisco novelties for campus networks.

Race Communications company presents
new Cisco Systems products
designed for building campus networks on the Russian market.
    The newly developed models 2948, 4000 and 6000
of the popular Catalyst switch family
allow you to create networks with a number of users
    up to 200 or more, and Selsius IP phones simplify
    organization of telephone communication on the scale of the office.

All switch models support
    means of QoS (Quality of Service, quality of service) and
organization of virtual LAN (VLAN), have
    high performance and have a low
price per port. The devices of the Catalyst family
run under the IOS operating system
(Internetworking Operating System), common to all network
    Cisco products, which guarantees full
    compatibility of the new and previously developed


    The Catalyst 2948, 4000 and 6000 switches provide
    duplex data transmission with allocation
    bandwidth for each
    user, preventing packet collision
(collision) in the local network. QoS support allows you to
    use new devices to transfer
    multimedia traffic (voice, data, video) with
the appointment of the necessary quality of service
    for latency-sensitive applications.


    According to Alexander Mikhlin, Race Manager
    Communications for Cisco products, the Catalyst 2948 model,
which performs level 2 switching, is ideal
    suitable for a small office LAN (24-50
users). This switch is available in
a fixed configuration: 48 ports 10/100 Mbit/s
    Ethernet and 2 Gigabit Ethernet ports. On all ports
    aggregation technology is supported
    EtherChannel traffic, bandwidth
    The switching mechanism is 24 Gbit/s.


    More powerful "floor level" switches
    The Catalyst 4000 and 6000 are designed to build
    medium and large networks (50-400 users).
    The 4000 models have a level 2 switching mechanism with
a bandwidth of 24 Gbit/s;
up to 96 ports can be configured in these devices
    10/100 Mbps Ethernet or up to 36 Gigabit Ethernet ports.
    Fault tolerance is achieved by installing
an additional power supply, supporting
UplinkFast/PortFast protocols when connecting
users and Fast/Gigabit EtherChannel when connecting to
the backbone.


    The bandwidth of the switching mechanism
of the 6000 models is from 32 to 256 Gbit/s. These switches
    process up to 200 million packets per second and
    provides service of the 2nd, 3rd and 4th levels.
    The fault-tolerant modular Catalyst 6000 devices
support up to 384 10/100 Mbit/s Ethernet ports and up to 130
Gigabit Ethernet ports.


    The release of a new NetFlow expansion board has also begun
    Feature Card II (NFFC II) for Catalyst 5000 switches, which
    allows you to perform level 3 switching,
    filtering protocols, providing QoS on
    based on the information of the L3 and L2 levels. Models 5000
    it is used to work in networks with a number of users
    100-200 or more.


    Race Communications experts believe that a good
addition to Cisco LAN products will be
    IP phones of the company she recently acquired
    Selsius. By implementing Voice over IP (VoIP, voice over IP) technology,
they will help to telephone a new office or
expand the network of telephone numbers when
    the possibilities of the institutional PBX have been exhausted.
    The IP phone is connected directly to the LAN or
in parallel to the switch port (without occupying the
data port), providing transmission
    voice traffic over an IP network. The phone has built - in
    the voice compression module according to the G.723 algorithm and the Ethernet port.


    "The emergence of new Cisco products implementing
Level 3 switching, QoS management, technology
    VoIP and much more, greatly simplifies
    creation of networks for the transmission of any type of traffic with
minimal costs and a high degree of
    payback," Dmitry Orlov noted,
    Technical Director of Race Communications.
