A

Access Control List (ACL)

Permits or denies incoming connections on

any of the management interfaces. It is an

ordered list of entries, each consisting of an

IP address and an optional wildcard “mask”

defining an IP address range, and a

permit/deny field.

Auto-negotiation

Gigabit Ethernet auto-negotiation allows the

link to synchronize with its peer

automatically.

B

Bump-in-the-wire topology

The SCE Platform physically resides on the

data link between the subscriber side and the

network side, and can both receive and

transmit traffic.

Bypass module

Separated hardware mechanism in SCE

Platforms, that forwards traffic

independently of the status of the rest of the

modules in the platforms.

C

Collection Manager (CM)

A software application that is responsible for

receiving RDRs from SCE Platforms and

processing them.

Command Line Interface (CLI)

One of the management interfaces to the

SCE Platform. It is accessed through a

Telnet session or directly via the console

port on the front panel of the SCE Platform.

Cutoff

Mechanism that cuts the link so that there is

no forwarding of traffic, and the physical

link is forced down (cutoff at layer 1).

D

DDoS Attack Filtering

The aim of DDoS attack filtering is to detect

attacks that occur in the traffic flowing

through the SCE platform, to report such

attacks via management channels, and to

handle these attacks by blocking them, if

configured to do so. In addition, if the

application loaded to the SCE 1000 supports

the ‘subscriber-notification’ feature, a

subscriber whose IP address is associated

with an attack that was identified can be

notified about the attack on-line by the SCE

1000.

There are two main aspects of attack

filtering:

• Attack detection: Detect attacks based

on their common IP address and number

of flows found to/from that IP address.

• Attack handling: Attack flows may be

blocked or processed as usual.
