GSMA Foundry Telco Edge Cloud trial interconnects two MEC platforms

Bridge Alliance, MobiledgeX, Singtel and Telefonica achieved an interconnection between two heterogenous multi-access edge computing (MEC) platforms as part of a GSMA Foundry Telco Edge Cloud trial. 

Bridge Alliance is a group of mobile operators in Asia Pacific, Middle East and Africa.

The hub-to-hub interconnection between the Bridge Alliance Federated Edge Hub (FEH) and MobiledgeX Edge-Cloud platform could allow edge applications to be deployed across different edge platforms and regions served by each hub. 

Singtel’s MEC and Telefonica’s MEC are connected by FEH and MobiledgeX Edge-Cloud platform respectively. With the interconnection, Singtel’s customers will be able to deploy edge applications on Telefonica’s MEC and vice versa, enabling multi-market services delivery across an extended geographical footprint, including Asia and Europe. Customers, developers, and partners can discover, as well as order cross-regional edge resources and deploy applications through a unified interface, ensuring a uniform experience across different networks and markets in these regions. Previously, interconnections were performed between operators on a one-on-one basis, making it difficult to scale the edge coverage.

Dr Ong Geok Chwee, CEO of Bridge Alliance, said, “We’re delighted to achieve this industry-first milestone with MobiledgeX and Telefonica. The implication of such hub-to-hub interconnections is that our member operators’ enterprise customers will be able to offer exciting data-intensive and low latency services in markets beyond our Asian footprint. We believe that this is only the beginning of more cross-regional edge deployments in the industry, which will occur as more of our member operators come on board our FEH, and as more trials between different edge hubs/aggregators are established. We welcome more edge hub partners on board.”

Michael Lochead, SVP of product for MobiledgeX said, “The true promise of edge computing hinges on seamless developer access for high-performance applications that can take advantage of global reach. Today’s announcement represents another major leap toward this goal, demonstrating that operators in disparate regions can choose the edge computing platform that best fits individual market needs while still easily achieving worldwide reach. We are proud to continue advancing edge compute possibilities with our operator partners as meaningful edge service rollouts are prepped for 2022 and beyond.”

AT&T and Intel co-develop advanced RAN pooling

AT&T is collaborating with Intel on an Advanced  base station distributed unit (DU) pooling technology designed to deliver unprecedented levels of elasticity in the RAN. 

AT&T says DU pooling provides the greatest value in C-RAN or Centralized RAN network deployments where RAN baseband equipment from many cell sites are “pooled together” into a “cloud” of general purpose processors in far edge data centers or central offices. Furthermore, through an advanced form of DU pooling called Class II pooling, a single 5G radio can now distribute the baseband processing for each user device in the cell across multiple servers.

DU pooling technology was made possible by combining AT&T’s Open RAN technologies as one of the co-founders of the O-RAN Alliance with Intel’s expertise in general purpose processors and software-based RAN through its FlexRAN software stack running on Intel 3rd generation Intel Xeon Scalable processors. The open standards for communications between radios and DUs that were published by O-RAN enabled its development, and the result is a technology demonstrator implemented on FlexRAN software.

Arista embeds network detection and response into switches

Arista Networks is adding embedded security and packet analysis capabilities to its 720XP series of switches. 

By embedding NDR (Network Detection and Response) capabilities into the Arista EOS-based switches themselves, Arista says it can deliver broader visibility and threat hunting across the modern cognitive campus. 

The new capabilities build on Arista's Autonomous Virtual Assist (AVA) platforms with two key components: AVA Sensors and the AVA Nucleus. AVA Sensors support a variety of form factors from stand-alone appliances and virtual to cloud workloads and now, within campus power over ethernet (PoE) switches. The AVA Sensors analyze the full packet, including application layer data which sets the stage for automated and manual threat hunting. The sensors then transfer the “just right” deep-packet data to the AVA Nucleus, which is offered as both on-premises and SaaS. 

Arista will deliver the capabilities via a switch software upgrade . The company cites minimal impact on switch performance or reliability.

“Network security has been an ongoing challenge for most organizations due to hardware deployments and configuration changes needed at the network infrastructure level. While organizations acknowledge that the network presents a unique vantage point, security teams have been forced to trade off network visibility and ongoing operational costs,” said Rahul Kashyap, Vice President and General Manager of Cybersecurity and CISO at Arista Networks. “By building NDR capabilities into the switching infrastructure itself, Arista enables a built-in, secure network that reduces organizational risk by speeding up both time to detection and time to remediation.”

The new capabilities are expected to be generally available in Q2, 2022, with early trials in March 2022.
