Edge STP

<h2 id="edge-stps-at-work">Edge STPs at work</h2>
<p>Unlike traditional STPs, Edge STPs process packet traffic away from the network core, where sensitive applications and customer information reside. They can either perform simple <a href="/facts/Packet_(information_technology)/xCYf8SJu">packet</a> routing or <a href="/facts/Deep_Packet_Inspection/NHd9q9zj">deep packet inspection (DPI)</a> that supports content-based <a href="/facts/Routing/Ml6MVCaC">routing</a>. DPI is a time-consuming and processor-intensive function that can bog down <a href="/facts/Core_network/EondGP5q">core network</a> functions and reduce customer response times. Shifting it to the network edge improves overall <a href="/facts/Network_Performance/ALjfw5Nn">network performance</a>. 
</p><p>Moving functionality to the network edge, companies can add, modify, and expand services without disrupting core network functions. Edge STPs perform a broad range of roles in evolving <a href="/facts/Telecommunications_network/NFCX0STS">telecommunications networks</a>. They include optimizing services such as <a href="/facts/Short_message_service/kacRfW0X">short message service (SMS)</a> for improved performance; providing precise security policies to <a href="/facts/Subnetwork/s1rQsNDv">subnetworks</a>; preventing service interruptions during switch migrations; and connecting server-based applications to switched networks. In the latter scenario, telecommunications companies that are implementing IP subnetworks use Edge STPs to integrate them with their existing SS7 signaling infrastructure.
