ALOE Transit SBC rev.1*

Target audience:- Any carrier whose network has IP borders with other networks

Reasons for deployment:Improving

- interoperability,

- information security, and

- network reliability

Deployment case:At the point where service provider networks interconnect, a solution for signaling and media control is necessary –

it is ALOE Transit SBC rev.1.

* Product release – October 2011

ALOE Transit SBC rev.1 in the Carrier’s Network

Placed at the border of carrier’s networks, ALOE Transit SBC:

• provides an intelligent interconnection between partners

• performs media anchoring through IP routing

• Allows for more efficient use of network resources

ina single, highly scalable

software platform

Functions

ALOE Transit SBC rev.1 delivers the following functions: Secure entry point into the carrier’s VoIP network

Network topology hiding

Centralized media traffic management

Maintaining SIP-related NAT-bindings

Access Control

Protocol and codec interworking

Key Benefits

• Advanced Routing

• Protocol Interworking

• Distributed Architecture with Centralized Management

• Media Anchoring• Access Control

• Dynamic Transcoding

• Network Security

• Distributed License

• Floating License

Network Security

• Network topology hiding from peering partners for information security (IP-address, etc.)

• Call authorization by IP address/username and password based on data from internal system’s configuration

• Ability to control incoming CPS/RPS value

• Privacy support (presentation/screening indicators, RFC3325/RFC4497/Cisco Remote-Party-id)

• NAT Traversal

Dynamic Transcoding

• Call-by-call transcoding (no need to transcode all calls of a trunk to the same codecs)

• Ability to set codec attributes for better interoperation with vendor’s and customer’s equipment

Access Control

Extensive access control

Only specific units of vendor’s/customer’s equipment can access the network

Internal code and operations are protected from outside influence and malicious attacks

Media Anchoring

Efficient media routing

Better control and knowledge of the RTP quality

(as RTP is anchored to interconnect SBC)

ALOE Transit SBCanchors media traffic at the border switch, so operator’s

internal IP addresses become hidden from the

outer endpoints

Distributed Architecture with Centralized Management

Single management point for geographically distributed system

Efficient load balancing and dynamic redistribution of workload allows for

– Efficient usage of hardware resources

– Increased overall reliability of the system

Zone traffic manager to ensure number translation and network access

Interworking

Multi-protocol support (SIP, H.323) for seamless interoperation with

multi-vendor and multi-protocol VoIP equipment

Protocol repair for smooth interworking

between different interconnect networks

NAT Traversal

Advanced Routing

Dynamic and static routing between interconnect peers

based on a diversity of parameters (ASR, gateway/route load, day of week, time of day, caller ID, etc.)

Routing based on received SIP 300/302 redirect messages

Deployment Case #1: ALOE Transit SBC for Network Security

Business Challenge

A carrier runs a network with a complex structure comprised of several different elements, each of which performs its own tasks.

One of the softswitches in the network has low capacity and can process no more than 100 CPS. Another softswitch is programmed to handle traffic from one particular client.

It is important for the carrier to keep this multivendor complex network structure functioning in case of a DDoS attack. Thus, the carrier’s requirements are the following:

•The network should be well protected from possible DDoS attacks

•The SBC should be able to work with various network elements from different vendors

Deployment Case #1: ALOE Transit SBC for Network Security

Solution from ALOE Systems

By installing ALOE Transit SBC the carrier will provide all network elements with necessary security.

Being the only traffic entry point into the network, ALOE Transit SBC hides the network topology, at the same time making traffic volumes equal for every element of the network by controlling the COS rates and signal protocols.

In case of a DDoS attack on the network only ALOE Transit SBC will be affected, leaving the complex network infrastructure untouched.

Network’s performance can be immediately resumed by running the IP address of the affected SBC on another server where ALOE Transit SBC is installed.

Deployment Case #2: ALOE Transit SBC for Special Routing Policies

Business Challenge

A carrier runs a network with a complex structure comprised of several different elements, each of which performs its own tasks.

The carrier needs to implement a solution for special customer / vendor routing policies in the network to route traffic to a particular interconnect peer.

The carrier’s requirements are the following:

•The specific routing should be performed by a separate element of the network (the existing softswitches should not be reconfigured)

•The structure of the network should remain the same

•The network should not be rebooted

•The issue should be solved with minimal expenses for the carrier

Deployment Case #2: ALOE Transit SBC for Special Routing Policies

Solution from ALOE Systems

A carrier can install ALOE Transit SBC for routing purposes: the product can be used to implement customer / vendor-specific routing policies.

ALOE Transit SBC can route traffic to a particular interconnect partner. Routing traffic to this partner is done through one interface.

Thus by using ALOE Transit SBC the carrier

•does not have to change the network structure;

•does not need to reboot the network;

•can solve the issue of routing traffic to a particular interconnect partner with minimal expenses.
