The Service Engine 2 (SE-2) is a high-performance aggregation router for
advanced service enforcement. In a compact form factor, the SE-2 offers up to
24Gbit/s packet processing through its powerful 16-core network processor
(NPU). The system offers a full Layer 2 bridging and Layer 3 routing featureset, allowing it to be used in all common broadband network architectures in
deployment today. The service enforcement features, including shaping,
policing, Quality of Service(QoS) and deep packet inspection can be applied on
both bridged and routed traffic.

The SE-2 provides cost effective
aggregation of all common access
technologies, such as ADSL2+,
xDSL, PON, Ethernet over COAX,
Wireless technology and more. Even
in a network with a mix of different
access technologies, the same
services can be provided on top of
all technologies – a homogenous
service portfolio for the network.
Using the SE-2 the network
operator can deliver a complete mix
of broadband services including
Internet, IP telephony and IPTV.
Service policies defined in the SE-2
are applied to users connected
through the access technology. The
SE-2 allows centralized expensive
BRAS solutions to be replaced by a
much more scalable and distributed
solution.
The SE-2 offers an expansion slot
that can hold an additional port
module to either increase the
number of Gigabit interfaces or to
provide 10Gbit/s uplinks to the
router.
The SE-2 can treat each service
individually, allowing multiple
services to the same end-user at
the same time. Each service can
have individual parameters for
packet filtering, bandwidth shaping
per host, per subnet, per VLAN or
per interface, parameters for QoS,
security and priority. Services can
be bridged or routed, even in
combination, and the same client
host can have multiple services
simultaneously where each service
can have a specific bandwidth and
a customized policy for routing or
bridging.
Using weighted fair queuing (WFQ),
clients receive optimal traffic
distribution between different
destinations.
The SE-2 provides a complete
feature set for network security.
Built in DHCP snooping and server
capabilities are used to enforce
network security and prevent users
from injecting malicious traffic. The
system prevents ARP, MAC and IP
spoofing and ensures Layer 2 traffic
separation between end-users.
The SE-2 also deploys the realtime
protocol monitoring of IPTV, a vital
tool to provide insight into the
quality of multicast IPTV streams in
the broadband network.
The programmable script motor
allows customized and
autonomous service control.
Service conditions and behavior
can be adapted to fit any type of
existing service deployment
structure used by operators.
Existing RADIUS based
mechanisms, used for xDSL,
can be reused by the SE2 which
reduces investment costs in the
OSS system for service providers
when new services are deployed
in the network.
802.1x or DHCP messages
activate a script in the
ASR6000. The script uses
programming logic to determine
what actions to take.
Examples of script actions are:


An authentication request
may be sent to a RADIUS
server, which can respond
with attributes that the
script converts into
configuration para-meters,
such as bandwidth control.
Content of DHCP server
responses can be analysed –
for example if an IPv6 prefix
delegation option is present,
a static route for the prefix
can be installed by the
script.
The SE2 supports the concept of
service templates. A service
template consist of the
configuration commands to activate
for a particular service. When a
trigger packet is received, the SE2
can interact with a central server to
determine which service to activate
for a client and then perform self
activation of configuration
commands. This allows per client
defined service parameters such as
bandwidth and QoS
Particularly in fibre-to-the-home
networks, TV distribution using IP
multicast is increasing. Networks
are deploying hundreds of TV
channels. Typical access switches
have relatively modest packet
buffers and operate at high speeds.
If the multicast source (TV playout)
generates a bursty media stream,
then the combined traffic of unicast
and multicast may cause buffer
exhaustion and packet drop. This is
experienced by the end user as
freezing pictures or even loss of
video.
The SE-2 is able to shape bursty
multicast traffic using the network
processor which will benefit any
switch-based access network
downstream of the ASR because
the traffic pattern of the multicast
stream is evenly distributed.
The SE-2 can also inspect
multicast MPEG streams using the
Realtime Protocol Monitoring
(RPM) feature to measure the
MPEG quality. The RPM feature
supports MPEG over RTP as well as
UDP, and collects and analyzes
metrics at RTP level, Transport
Stream level and Packetized
Elementary Stream level. The errors
detected include:

sequence-error per RTP
multicast group

jitter per RTP multicast
group

missing-sync-byte per TS
multicast group

misaligned per TS multicast
group
Any detected errors can be logged,
read using SNMP, or shown by the
ASR CLI. Each ASR that runs RPM
becomes a probe, capable of
monitoring up to 50 TV channels at
the same time. If an end user
reports a problem with the TV
service, the RPM data provides an
immediate notification if a problem
is seen in the network, and if it
affected the entire network or only
a part of the network. The RPM
data may even help network
engineers to pinpoint the location
of the problem in seconds, instead
of the usual hours, or even days, of
manual troubleshooting.
When used in Layer 3 mode, each
port on the SE-2 can connect to a
different end user. Layer 3 ports
towards a large population normally
require heavy IPv4 subnetting
which rapidly consumes crucial
IPv4 address space.
iBOS contains a set of features
that allows an IPv4 subnet to
be shared among end user
clients connected on different
Layer 3 ports – even across
ASRs! Clients are made to
believe they share a larger
subnet, but any traffic between
clients within the subnet is routed
through and between ASRs. The
result is secure Layer 3 separation
between end users, a routed
topology for easy network
management, and maximum use of
scarce IPv4 address space..
The exhaustion of IPv4 address
space means that IPv6 deployment
is now mandatory in most networks.
The SE2 supports unicast IPv6
forwarding. Policies for traffic
management and QoS also support
IPv6 which means that a client can
use either IPv4 and IPv6, or both.
